The disease has been observed since 1978 during warmer water periods. Following the 1982-1983 El Nino, the disease and severe sea star population declines were observed, however, quantitative surveys of disease were not conducted. In our 1997 surveys, Asterina miniata and Pisaster giganteus were the species most severely affected; however, the disease was also observed in Astropecten armatus, Dermasterias imbricata, Henricia leviuscula, Mediaster aequalis, Orthasterias koehleri, Pisaster brevispinus, Pisaster ochraceus, and Pycnopodia helianthoides. Three species were not observed with the disease (Henricia sp., Astropecten verrilli, and Luidia foliolata); however, these species were rare. Population declines that might have resulted from disease are apparent in monitoring data from the Channel Islands Research Program and the Channel Islands National Park. Surveys at Catalina Island indicate that population declines occurred in summer and were not the result of winter El Nino -associated events such as storms or increased rainfall. In 1997, wasting disease was observed in other echinoderms (Echinoids, Ophiuroids, and Holothuroids) as well.

Randomly Amplified Polymorphic DNAs (RAPDs), and Polymerase Chain Reaction (PCR), we have begun to examine regions associated with molecular markers in the sea scallop, Placopecten magellanicus. P. magellanicus samples were obtained from several regions off the Northeast Atlantic coast at multiple sites around Georges Bank and from the southeastern Canadian waters. We analyzed samples from both inside & outside of the United States governmental restricted area. Preliminary screening of a Placopecten magellanicus genomic library seems to reveal positive clones using primers made to both Drosophila melanogaster (fruit fly) histone H2A-H2B and to the Pisaster ochraceus (sea star) H3 histone gene. Preliminary comparisons were made with the bay scallop Argopecten irradians. Further analyses should result in the identification of a series of polymorphic regions in both Placopecten magellanicus and Argopecten irradians as well as provide basic molecular biology characterization of the highly conserved histone gene family in mollusks.

AUTHOR(S): Navarrete,-S.A.; Menge,-B.A.; Daley,-B.A. AUTHOR AFFILIATION: Departamento de Ecologia and Estacion Costera de Investigaciones Marinas, Pontificia Universidad Catolica de Chile, Casilla 114-D, Santiago, Chile SOURCE (BIBLIOGRAPHIC CITATION): Ecology 2000 vol. 81, no. 8, pp. 2264-2277 INTERNATIONAL STANDARD NUMBERS: ISSN 0012-9658 PUBLICATION YEAR: 2000 LANGUAGE OF TEXT: English LANGUAGE OF SUMMARIES: English PUBLICATION TYPE: J (Journal-Article) ABSTRACT: Most natural food webs have more than one predator species, and many have trophic interactions among these predators. When a top predator feeds on an intermediate predator and they both feed on a shared basal resource, a phenomenon labeled intraguild predation (IGP), the potential exists for complex food web dynamics due to predation and competitive effects. Here we investigate the relative importance of direct predation vs. competition by a top predator on an intermediate predator. The study system is the rocky intertidal interaction web formed by the predatory seastar Pisaster ochraceus, the predatory whelks Nucella emarginata and N. canaliculata, and a shared resource species, the mussel Mytilus trossulus. Previous experiments documented strong negative effects of Pisaster on mussels and whelks, but the mechanisms responsible for the effects on whelks, whether competition or predation, were not identified. Here we report results of a field experiment that manipulated both Mytilus and Pisaster to determine the short- and longer-term changes in whelk populations. Using a simplified dynamic model for changes in abundance over the initial stages of the experiment, we separated and quantified the top-down effect of direct predation by seastars vs. the bottom-up effects of competition and food limitation. Short-term results were in agreement with longer-term responses. Results suggest that direct and indirect bottom-up influences of mussels were far stronger than predation, and thus, whelk increases in the absence of seastars were due to reduced competition with Pisaster. Large differences between the body sizes of seastars and whelks make it difficult to determine the ultimate nature of the resource under competition between predators. Small mussels may constitute only a food resource for seastars, but to some extent, they also represent a microhabitat for whelks. Differences in the magnitude of the response to mussel manipulations between Nucella species might be due to slight differences in the way the species utilize mussel beds. Some of the predictions of theoretical IGP models regarding coexistence and stability of species may not apply to this interaction web because it includes species with both "open" and "closed" populations, rather than just closed populations as assumed by the models.

Controls consisted of embryos raised at 1 x g (1G) in flight and embryos raised at 1G on the ground. Experimental organisms and controls were fixed on mission days (MD) 3, 4, 5, 6, and 7 and one sample was returned alive. Comparison of the mu G embryos with the 1G in-flight controls and ground controls suggests that there is little difference in size and overall development. Scanning electron microscopic examination of the development of the esophageal musculature showed that the pattern of development and differentiation was normal and was the same in both the in-flight and ground controls. The esophageal muscle cells of specimens returned alive after 10 days in mu G contracted normally. Detailed transmission electron microscopic examination of MD 7 embryos revealed a decreased amount of sarcoplasmic reticulum in the mu G embryos compared with both MD 7 1G in -flight and ground controls. These results suggest that while exposure to mu G may slow muscle differentiation slightly, it has little overall effect on embryos/larvae of up to 7-8 days of development.

Adult Pisaster ochraceus were collected from Point Caution (a wave-protected site) and Mar Vista (a wave-exposed site) on the San Juan Islands. Seastars from the wave-exposed site were larger and had larger pyloric caeca while those from the wave-protected site were smaller with smaller pyloric caeca. Bigger females produced smaller eggs with a low biochemical content/egg and smaller females produced bigger eggs with a high biochemical content/egg. Egg quality and larval food had a significant effect on larval growth, development and survival. Bipinnariae from large eggs were initially bigger with faster developmental rates than those from small eggs. When starved, the numbers of bipinnariae surviving later on in development were higher for those from large eggs than for those from small eggs. When fed, the numbers of larvae surviving was higher for those from small eggs. This suggests that for this species large and small eggs might have equivalent fitness depending on the environmental conditions in which the offspring develop. All bipinnariae responded to food scarcity by changing their form, with those from smaller eggs responding to food scarcity later than those from larger eggs. Starved early bipinnaria stages were longer and wider and fed bipinnariae were narrower and shorter. Wider bipinnariae with larger mouths and stomachs were able to progress to more advanced stages while those with smaller internal structures could not. Thus for this species the mere increase in bipinnaria length and width might be insufficient to ensure continued larval development under food-limiting conditions; changes in internal morphology such as increase in the size of the digestive tract might be necessary.

During the last 10 yr, information on dominant cover was collected from permanent plots at 14 stations around Santa Barbara, Anacapa, Santa Rosa, and San Miguel Islands. While abundances of most organisms remained stable, there were differences between sites. Experimental trample and scrape plots at Anacapa showed slow recovery in the mussel (Mytilus californianus) and rockweed zones (Pelvetia fastigiata/Hesperophycus harveyanus). Accidental clearings by grounding of vessels or buoys at Santa Barbara Island showed rapid recovery. A natural influx of sea stars (Pisaster ochraceus) at Santa Rosa Island caused dramatic declines in the mussel population there. A mass mortality of black abalones (Haliotis cracherodii) was documented. We observed a parkwide decline of more than 90% from 1985 population numbers. While withered and weak abalone were frequently observed, no direct cause for the mass mortality was found.

Field and laboratory experiments showed that a slight decrease in water temperature dramatically reduced the effects of a keystone predator, the sea star Pisaster ochraceus, on its principal prey. Ongoing changes in patterns of cold water upwelling, associated with El Nino events and longer term geophysical changes, may thus have far-reaching impacts on the composition and diversity of these rocky intertidal communities.

Based on treatments with inositol 1,4,5-trisphosphate (IP sub(3)) or caffeine in the presence or absence of low-molecular-weight heparin (a competitive inhibitor of IP sub(3)-sensitive receptors), prophase-arrested oocytes were capable of mobilizing internal stores of bound calcium via IP sub(3)-sensitive or IP sub(3)-insensitive receptors. The amplitudes of the calcium transients elicited by caffeine or IP sub(3) were similar to those obtained at fertilization. However, fertilization-induced transients were significantly more prolonged than were caffeine- or IP sub(3)-mediated transients, which suggests that the kinetics of the calcium transients can be affected by the type of stimulatory agent. In prophase-arrested oocytes that were treated with the maturation-inducing hormone 1-methyladenine (1 -MA), distinct calcium transients were typically lacking prior to germinal vesicle breakdown (GVBD), indicating that nuclear disassembly can occur without marked calcium spikes during meiotic maturation. When subjected to monospermic fertilizations, however, both prophase-arrested and maturing oocytes showed a single, prolonged increase in free calcium that travelled in a wavelike fashion throughout the oocyte at one fourth mu m/s. Compared to the calcium waves of normally developing specimens that were fertilized after GVBD, fertilization waves in prophase-arrested specimens decayed more rapidly and typically lacked a well defined wave front, indicating that the propagation patterns of the waves can differ depending on the state of oocyte maturation. Within 90 min after fertilization, most starfish zygotes began to display repetitive calcium oscillations in "dual -channel" ratioed images obtained using dextran-conjugated forms of the calcium-sensitive fluorochrome Calcium Green and the calcium-insensitive dye Rhodamine. Each transient constituting these oscillations lasted arrow right -3 min and tended to be enhanced in the cortical cytoplasm. Calcium oscillations often preceded nuclear envelope breakdown (neb), anaphase onset, and cleavage furrow formation during the first cell cycle and continued through the first five cleavages in specimens that developed into normal blastulae. In oocytes microinjected with colchicine to arrest cytokinesis, calcium transients also occurred in the absence of cell divisions, indicating that calcium transients can be uncoupled from cytokinesis. In addition, injections of low-molecular-weight heparin - but not the control molecule de-N-sulfated heparin - caused abnormal fertilization-induced calcium dynamics in a dose-dependent fashion and typically abolished marked post-fertilization calcium oscillations, neb, and normal cleavage. Collectively, these imaging analyses reveal that the spatiotemporal patterns of intracellular calcium transients can change during starfish early development and suggest that IP sub(3)-mediated calcium release is involved in producing a complex repertoire of free calcium elevations that may in turn help regulate normal development.

The nature of the 'acceleration' of meiosis was studied using Pisaster ochraceus oocytes. The extent of the acceleration of first polar body formation was found to be completely dependent on the time of fertilization (or artificial activation); fertilization at about 100 min after 1-methyladenine application accelerated meiosis I the most, while earlier or later fertilization resulted in a smaller extent of accelerations of meiosis I. Observation of isolated meiotic spindles and fluorescent visualization of meiotic spindles in whole oocytes showed that progression of meiosis I in Pisaster oocytes pauses transiently at metaphase I for more than 40 min unless they are activated. The activation shortened the duration of metaphase I, which resulted in the acceleration of first polar body formation. A new term 'metaphase pause' is proposed to define this long duration of metaphase I in starfish oocytes.

Pisaster matrix-1 was first observed in endodermal cells of the early gastrula, and shortly thereafter it was secreted into the blastocoel where it accumulated steadily during gastrulation. During the late gastrula stage it also appeared in the extracellular matrix (ECM) of the gut lumen. Immunogold electron microscopy with anti-PM1 revealed that PM1 was found in condensations of ECM associated with blastocoel matrix fibers, in the trans Golgi network, in Golgi-associated vesicles in endoderm and mesenchyme cells and throughout the ECM lining the digestive tract of late gastrula and bipinnaria larvae. When blastula or early gastrula stage embryos were grown in the presence of the PM1 antibody, archenteron elongation, bending and mouth formation failed to occur. Pisaster matrix-1 stained with alcian blue and its assembly could be disrupted with the common inhibitor of O-linked glycosaminoglycan assembly, beta -xyloside but not by tunicamycin. It was not sensitive to enzymes that degrade vertebrate proteoglycans. Pisaster matrix-1 is a large (600 kDa) proteoglycan-like glycosaminoglycan, secreted exclusively by endodermal and/or endodermally derived cells that may be necessary for morphogenesis of the mouth and digestive tract of Pisaster ochraceus embryos/larvae.

Biol. Sci., Univ. California, Santa Barbara, CA 93117-9610, USA SOURCE (BIBLIOGRAPHIC CITATION): ECOL.-MONOGR. 1996 vol. 66, no. 4, pp. 409-429 INTERNATIONAL STANDARD NUMBERS: ISSN 0012-9615 PUBLICATION YEAR: 1996 LANGUAGE OF TEXT: English LANGUAGE OF SUMMARIES: English PUBLICATION TYPE: J (Journal-Article) ENVIRONMENTAL REGIME: M (Marine) ABSTRACT: The application of basic ecological concepts to fields of conservation biology and applied environmental sciences is a healthy sign, but before these concepts are widely used, ecology must provide operational definitions and quantifiable methods. Keystone species and interaction strength are concepts with deep practical and theoretical implications. We studied the strength of predation on mussels (Mytilus trossulus) by the keystone seastar Pisaster ochraceus and the whelks Nucella emarginata and N. canaliculata under different environmental conditions in the Oregon intertidal zone. We attempted to determine: (1) the sensitivity of keystone predation to the presence of other predators in the system; (2) the role of other predators in the presence and absence of a keystone species; and (3) the per capita and population-level variability in interaction strengths of strong (keystone) vs. weak interactors. Predation intensity on mussels was measured by recording the survival of mussels transplanted to areas from which seastars, whelks, or both, had been either manually removed or left undisturbed at natural densities. Whelk experimental units were nested within those for the seastar treatment to account for the much larger body size and greater mobility of seastars. Each combination of seastar and whelk treatment was replicated four times in both wave-exposed and wave-protected habitats of two sites that differed in predator densities, primary productivity, and recruitment and growth rates of prey species. Predation intensity by the keystone predator was strong under all site X wave exposure combinations, and was unaffected by the presence of whelks. Whelks, in contrast, had ecologically important effects on mussel survival in the absence, but not in the presence, of the keystone predator. Population (total) interaction strength between seastars and mussels was 2-10 times stronger than that between whelks and mussels across sites and wave exposures. Per capita interaction strength of seastars was two to three orders of magnitude larger than that of whelks. However, per capita effects of seastars were more variable between sites and wave exposures, probably because simple density values grossly underestimate the ability of mobile predators to localize prey. Such interactive effects and variability in interaction strengths between keystone and weak predators may characterize all keystone predator -dominated systems, but data currently are insufficient to test this proposition. Negative effects of seastars on whelk density were observed <4 mo following initiation of Pisaster removals. Seastars also had a negative effect on whelk sizes, which took longer to appear, after 6 mo of continuous Pisaster removal. Negative effects of seastars on whelks appeared to be stronger in places with higher densities of predators, partially explaining the reduced predation intensity of whelks observed in the presence of seastars. Our results support the idea that in keystone -dominated systems, species other than the keystone species have only minor, if any, effects on the rest of the community, and thus might be cited by some as "redundant species." However, our results also indicate that, after the loss of a keystone species, previously "redundant" species can partially compensate for the reduced predation and adopt a major role in the altered system. Such responses are potentially an important force in stabilizing communities. Further, such possible compensatory capabilities of alternative consumers suggests that, at least for predators, the term "redundant species" conveys an inaccurate image of the potential importance of weak interactors and should be abandoned.

PUBLICATION YEAR: 1995 LANGUAGE OF TEXT: English LANGUAGE OF SUMMARIES: English PUBLICATION TYPE: J (Journal-Article) ENVIRONMENTAL REGIME: M (Marine) ABSTRACT: Specimens of Pisaster ochraceus, an intertidal carnivorous seastar, were collected in northern Puget Sound at Post Point, near Bellingham, Washington, USA, in November 1993, and used in experimentation through September 1994. Ammonium sulfate fractions (60% precipitates) from excised pyloric caeca (digestive glands) possessed beta -glucanase activity directed toward such beta -linked substrates as carboxymethylcellulose (CMC), partially-digested cellulose (cellodextrins) and the synthetic substrate p-nitrophenyl- beta -D-glucoside (PNDG). pH-activity and pH -stability maxima were at pH 6 and 5, respectively. No hydrolytic activity was detectable on native cellulose, native chitin or on cationic-modified celluloses such as DEAE-cellulose. Gel filtration (Sephadex G-100) of this 60% precipitate followed by DEAE-Sephadex column chromatography revealed heterogeneity of beta -glucanase activity, with an indication of up to 11 distinct fractions with variable activity directed toward the substrates indicated above (CMC, cellodextrins and PNDG). These fractions displayed differing ratios of hydrolytic activity on these substrates. None of the isolated fractions displayed activity toward either native cellulose or native chitin. Gut extracts from the edible mussel (Mytilus edulis, a common prey species of P. ochraceus, were shown to possess partially digested cellulose (cellodextrins). These cellodextrins were further degraded by seastar beta -glucanases in vitro. The digestion of the gut contents of ingested prey provides a possible adaptive explanation for the presence of beta -glucanase activity in a carnivore.

Data were assembled from the literature and included two asexual species, Linckia multifora and Nepanthia belcheri; two brooders, Asterina phylactica and Leptasterias hexactis; one species with benthic eggs that does not brood, Asterina gibbosa: one species with lecithotrophic development in the plankton, Patiriella pseudoexigua; and one planktotrophic species. Pisaster ochraceus. A negative correlation was found between first-year survival and adult survival rates which also correlated with mode of reproduction: highest adult survival and lowest hrst-year survival was found for P. ochraceus, the planktotropihic species, and lowest adult survival was coupled with highest lilst-yeal survival in asexual species. A matrix model was developed to explore the metapopulation consequences of different modes of reproduction. Asexual species are similar to species with planktonic larvae that also have long-lived adults in that both are well hisulated from the vagaries of planktonic life one by avoiding the plankton all together and the other by having very low transition probabilities for the first year of life but high transition probabilities for retention of adults hl the population. Species with short-lived adults and planktonic development of larvae are more closely tied to changes in first-year survival rates with respect to over-all dynamics of metapopulations.

The genes for 13 proteins, two rRNAs and 22 tRNAs are organized in an extremely economical fashion, similar to those of other animal mtDNAs, with some of the genes overlapping each other. The gene organization is the same as that for another echinoderm, sea urchin, except for the inversion of a 4.6-kb segment that contains genes for two proteins, 13 tRNAs and the 16S rRNA. Judging from the organization of the protein coding genes, mammalian mtDNAs resemble the sea urchin mtDNA more than that of the starfish. The region around the 3' end of the 12S rRNA gene of the starfish shows a high similarity with those for vertebrates. This region encodes a possible stem and loop structure; similar potential structures occur in this region of vertebrate mtDNAs and also in nonmitochondrial small subunit rRNA. A similar stem and loop structure is also found at the 3' end of the 16S rRNA genes in A. pectinifera, in another starfish Pisaster ochraceus, in vertebrates and in Drosophila, but not in sea urchins. The full sequence data confirm the presumption that AGA/AGG, AUA and AAA codons, respectively, code for serine, isoleucine, and asparagine in the starfish mitochondria, and that AGA/AGG codons are read by tRNA super(S) sub(G) super(e) sub(C) super(r) sub(U), which possesses a truncated dihydrouridine arm, that was previously suggested from a partial mtDNA sequence. The structural characteristics of tRNAs and possible mechanisms for the change in the mitochondrial genetic code are also discussed.

Recent evidence has suggested, however, that the madreporite may be significant in the replenishment of general body fluid. This hypothesis has been tested. The madreporite openings of an intertidal starfish, Pisaster ochraceus, were obstructed with cement, and the animals were used in controlled experiments to compare weight (volume) changes under stable conditions, in response to air drying and recovery, and during adaptations to hyper- and hypoosmotic environments. Over a period of days, normal animals showed positive and negative volume fluctuations of up to about 20% (in part related to posture). Animals with obstructed madreporites generally did not gain weight and were significantly less able to maintain body volume or recover from fluid losses resulting from the stresses applied. The madreporite seemed to contribute little to the initial osmotic responses, but it did participate in subsequent volume readjustments in a hyperosmotic medium that had induced fluid losses. Obstruction of the madreporite did not impede tube foot activity, but may have caused some diversion of general body fluid to the ambulacral system. Rates of seawater uptake through the madreporite of 2.2-2.6 mu l/g/h were calculated from observed maximum mean differences in weight changes.

Yolk granules are thought to provide the developing embryo with nutrients essential for its survival, while other granules contain proteins such as enzymes and extracellular matrix components that are required for fertilization and perhaps for early development. This study uses immunofluorescence and immunogold techniques with two novel monoclonal antibodies against proteins found in egg yolk and cortical granules to study the localizations of these antigens during early starfish (Pisaster ochraceus) development. Partial biochemical characterizations using the anti-yolk antibody have revealed that there are a family of structurally related proteins in oocyte yolk granules and that while the molecular compositions of the yolk proteins change during embryogenesis, their depletion is not significant until the larval stage, suggesting these proteins are not required for early development. In addition, a large immunoreactive protein has been found in the intestine and coelomic fluid, suggesting that, as in other species, the starfish yolk proteins may be derived from a large precursor, such as vitellogenin. Analysis of the anti -cortical granule antibody has revealed that a 120-kDa antigen is stored in cortical granules of unfertilized eggs. Upon egg activation, the cortical granules located in the peripheral egg cytoplasm undergo exocytosis, and the 120-kDa antigen is released into the perivitelline space. However, other granules, which are also labeled by this antibody, remain dispersed throughout the egg cytoplasm and are still present in the early gastrula, where they appear to contribute to the extracellular matrices of the developing embryo. This suggests that starfish cortical granules play a dual function: At fertilization, where they help create a block to polyspermy, and in embryonic development, where they secrete extracellular matrix components.

We investigated variation in interaction strength between the original keystone predator, the seastar Pisaster ochraceus, and its primary prey, mussels (Mytilus californianus and M. trossulus). The study was prompted by differences in community structure at two low zone sites along the central Oregon coast, Boiler Bay (BB) and Strawberry Hill (SH). To test the hypothesis that variation in predation strength explained some of these differences, we examined the seastar-mussel interaction at locations with high and low wave exposure at both sites. Predation intensity varied greatly at all spatial scales. At the two largest spatial scales (10's of kilometres, 100's of metres), differences in both survival of transplanted mussels and prey recolonization depended on variation in seastar abundance with site, wave exposure, prey recruitment and growth, and at SH protected, the extent of sand burial. Variation at the two smallest scales (metres, 10's of metres) was high when seastars were scarce and low when seastars were abundant. Transplanted mussels suffered 100% mortality in 2 wk at wave-exposed SH, but took >52 wk at wave -protected BB. Seastar effects on prey recolonization were detected only at the SH wave-exposed site. Longer term results indicate that, as in Washington state, seastars prevent large adult M. californianus from invading lower intertidal regions, but only at wave-exposed, not wave -protected sites. Thus, three distinct predation regimes were observed: (1) strong keystone predation by seastars at wave-exposed headlands; (2) less-strong diffuse predation by seastars, whelks, and possibly other predators at a wave-protected cove, and (3) weak predation at a wave -protected site buried regularly by sand. Comparable experimental results at four wave-exposed headlands (our two in Oregon and two others in Washington), and similarities between these and communities on other West Coast headlands suggest keystone predation occurs broadly in this system. Results in wave-protected habitats, however, suggest it is not universal. Combining our results with examples from other marine and non-marine habitats suggests a need to consider a broader range of models than just keystone predation.

S1-like immunoreactivity, was found in the larvae of the asteroids Pisaster ochraceus and Asterias rubens (Echinodermata: Asteroidea), originating in the apical region and becoming concentrated as two groups of cells in the dorsal ciliary band, the preoral transverse and adoral ciliary bands in larvae up to the early brachiolarian stage (five weeks). The pattern of serotonin immunoreactivity, although appearing earlier in the apical nerve plexus, is very similar to that of the peptide, with paired groups of immunoreactivity apparent in the dorsal ciliary band. This evidence, together with other recent studies, indicates that this neuropeptide is present in both the larval and adult nervous system, despite the complete reformation of the system at metamorphosis. The close localization of S1 with serotonin may also suggest a possible function for the peptide in larval and adult nervous systems.

Ordinarily, this axis of polarity is revealed by the eccentric germinal vesicle that is displaced toward the animal pole where polar bodies eventually form. In addition, however, the cortex at the animal pole is characterized by a pre-meiotic aster (centrosomes and bundles of microtubules lying within folds of the nuclear envelope), an absence of large, so-called "acidic vacuoles" that occur abundantly everywhere else, a diminished ability to form actin-filled spikes, and local mechanical weakness. These expressions of the A-V axis within the cortex are documented by micrographs. The problem of distinguishing if any feature is an "expression" or a "determinant" of axial differentiation is briefly discussed.

When fixed in the presence of alcian blue the jelly coat is seen to be made up of three regions, an inner layer consisting of a meshwork of fibres, a middle layer of thicker fibres, and a dense outer layer. At fertilization the cortical granules release their contents into the potential space between the vitelline layers and a low fertilization membrane consisting of the vitelline layer and a dense component of the corticle granule is formed. Attempts to identify elements of the hyaline layer by immunofluorescence demonstrated that it appears to bind both antisera and control sera in a nonspecific manner.

Newly settled recruits were observed at high densities subtidally in the channel (mean maximal density = 1.23 x 10 super(4)/m super(2)) and at nearby sites. Subsequent surveys in 1988 to 1991 and size-frequency distributions of adults indicated strong yearly recruitment of P. ochraceus. Recruits of P. ochraceus were found on all available substrata, including hard and soft bottoms and on benthic algae. The initial food of the recruits included newly settled mussels (Mytilus), snails and barnacles. Recruitment of the forcipulate Pycnopodia helianthoides was observed in 1987 to 1989 and in 1991, while recruitment of the spinulosan Dermasterias imbricata occurred only in 1988. High densities of planktonic bipinnaria larvae were found in the bay of Boca del Infierno in late May. We hypothesize that the high density population of adult P. ochraceus found in the channel of Boca del Infierno spawns synchronously and most of the resulting embryos and larvae are retained within the bay.

M. californianus form extensive beds, up to 1 meter deep, in the mid- but not the low intertidal zone. The possibility was explored of opening up the low intertidal zone to mussel production by 1) monitoring the growth of caged mussels in low and mid-intertidal cages and by 2) monitoring the survival of transplanted mussels in low intertidal starfish removal and control plots on the central Oregon coast. The growth rate of mussels was greater in low than in mid- intertidal cages; and greater in wave exposed than in protected cages. After two months the survival of mussels transplanted to the low intertidal was between 50 and 75% in starfish removal plots and between 0% and 75% in control plots. Even though mussels grow better in the low than in the mid- intertidal zone, one would have to remove starfish at least every 2 weeks before permanent mussel beds could be maintained in the low intertidal zone. Since storms make the low intertidal inaccessible during most of the winter, it appears that starfish removal will not be a practical management tool for increasing mussel productivity.

Ten seastar collections from five locations in Alaska, representing five species and three genera in the family Asteridae were analyzed for allozyme variation at 16-25 loci. Three brooding species (Leptasterias polaris, L. epichlora, and L. hexactis) and two broadcast-fertilizing species with long planktonic larval periods (Evasterias troschelii and Pisaster ochraceus) were studied. Population differentiation of L. epichlora (F sub(ST) = .154) was much higher than for P. ochraceus (.005) or E. troschelii (.024). Earlier work in our laboratory found that L. hexactis also showed significant interpopulation differences in allele frequencies (F sub(ST) = .332). Expected heterozygosity was .05 in E. troschelii, .08 in L. polaris, .09 in P. ochraceus, .14 in L. epichlora, and .17 in L. hexactis. Heterozygosity is unrelated to either body size or mode of reproduction in these species.

Embryos appear to be best preserved by freeze substitution and demonstrate a HL consisting of at least six distinct sublayers. Based on staining with anionic dyes, most sublayers appear to contain glycosaminoglycans. Freeze substituted embryos, which were also stained with monoclonal antibodies raised against their ECM, revealed that some molecules are common to all six sublayers, whereas other molecules may be restricted to specific sublayers. This suggests that each sublayer could have a different function.

It has been suggested that cytokines, analogous to vertebrate interleukins, are involved in mediating these responses, though how they may function is not known. Using a mouse thymocyte proliferation assay we confirm that cytokine activity, which can be blocked with antibodies to mammalian IL-1 alpha , can be extracted from coelomic fluid of the starfish Pisaster ochraceus . A subset of starfish coelomocytes in primary culture will readily phagocytose bacteria added to cultures. In a microscopic assay the proportion of coelomocytes that will phagocytose bacteria increases significantly when cultures are treated with recombinant IL-1 alpha , yet the number of phagosomes per cell remains constant. We propose that endogenous interleukins stimulate recruitment of phagocytic cells as part of the non-specific cellular defence mechanism of asteroids.

Time-lapse video recordings reveal that the nucleus lengthens along the animal-vegetal axis of the oocyte directly prior to GVBD. The microtubule-altering drugs also do not affect the time at which GVBD begins or ends. A 10 mu M solution of the microfilament-disrupting drug cytochalasin B (CB), on the other hand, essentially eliminates the pre -GVBD elongation of the nucleus. CB also slightly delays the onset of GVBD and significantly lengthens the time required to complete GVBD. Such studies suggest that: drug-sensitive microtubules are not required for GVBD to proceed in a normal fashion; the pre-GVBD changes in nuclear shape involve microfilament-mediated events; and cytochalasin-induced depolymerization of microfilaments retards the normal timing of GVBD.

The large-meshed network resembles a snood (hair net). Snood fibers form loops and branches throughout the cortex of a premeiotic oocyte, except at the animal pole where they emanate from a nonstaining zone surrounding the centrosomes. Snoods are not colocalized with the cortical arrays of microtubules and are unaffected by drugs that disrupt microtubules or microfilaments. Stimulation of oocyte maturation by 1-methyladenine causes snoods to disappear, presumably by disassembly, about halfway to the time of germinal vesicle breakdown. They do not reappear during meiosis, fertilization, or development to the two-cell stage, and their functional importance, if any, during oogenesis or development remains to be elucidated.

A 44-kDa MBP kinase (p44 super(mpk)) purified from mature sea star oocytes is shown here to be phosphorylated at tyrosine. Antiserum to purified sea star p44 super(mpk) was used to identify antigenically related proteins in Xenopus oocytes. Two tyrosine -phosphorylated 42-kDa proteins (p42) were detected with this antiserum in Xenopus eggs. Xenopus p42 chromatographs with MBP kinase activity on a Mono Q ion-exchange column. Tyrosine phosphorylation of Xenopus p42 approximately parallels MBP kinase activity during meiotic maturation. These results suggest that related MBP kinases are activated during meiotic maturation of Xenopus and sea star oocytes. Previous studies have suggested that Xenopus p42 is related to the mitogen-activated protein (MAP) kinases of cultured mammalian cells. We have cloned a MAP kinase relative from a Xenopus ovary cDNA library and demonstrate that this clone encodes the Xenopus p42 that is tyrosine phosphorylated during oocyte maturation. Comparison of the sequences of Xenopus p42 and a rat MAP kinase (ERK1) and peptide sequences from sea star p44 super(mpk) indicates that these proteins are close relatives.

At 13 degree C, prophase-arrested oocytes of Pisaster ochraceus begin GVBD and rapidly undergo nuclear envelope disassembly about 50 min after addition of the maturation-inducing hormone 1-methyladenine (1-MA). The nuclear lamina of these oocytes, however, remains present for 10-20 min following the vesiculation of the nuclear envelope. Completion of GVBD, as evidenced by a blending of the nuclear contents with the surrounding cytoplasm, occurs within about 15 min after the nuclear lamina has fully depolymerized.

The intron position at codon 150, although present in higher vertebrate actins, has not been reported in actin genes from invertebrates. The presence of 5' and 3' splice junction sequences in the 5' flanking region of the Cy gene suggests the potential for an intron there.

Prey-size preference was positively correlated with predator size. Measurements of the force required to dislodge mussels from the substratum and conspecifics showed an increasing exponential relationship with mussel size. Size selective feeding may be an energy maximizing and time minimizing strategy, where energy gained from choosing larger mussels is balanced against disproportionately increased costs in energy and time of removing large mussels from the substratum.

These enzymes have been partially purified and characterized and display tryptic, chymotryptic and carboxypeptidase A-like activity. The tryptic and chymotryptic enzymes are inactivated by phenylmethylsulfonyl fluoride, indicating that all are serine proteases. Both Trypsins are inhibited by soybean trypsin inhibitor. The chymotrypsin was inhibited by tosyl-L-phenylalanine chloromethyl ketone. Both reagents indicate the involvement of histidine in the active site. The low molecular weight trypsin and the chymotrypsin were able to activate bovine trypsinogen to trypsin, as determined in a modified PAGE electrophoresis with trypsinogen and casein copolymerized in the gel.

The difference in consumption between limpet species appeared to be a function of ability to avoid capture. Laboratory studies showed that N. scutum could outrun the seastar but C. pelta could not. N. scutum has longer cephalic tentacles than C. pelta which appeared to allow an earlier tactile warning of the seastar's presence. Both species were able to sense the seastar at a distance, but they responded differently. N. scutum tended to move away from the predator but C. pelta merely moved a greater distance in the direction it was originally facing. C. pelta is most abundant in the upper intertidal while N. scutum and P. ochraceus are most abundant in the lower intertidal. With better escape mechanisms, N. scutum should be more able to coexist with the seastar than C. pelta and it is suggested that predation pressure may be a possible explanation for the vertical distribution of the limpets.

The microtubules were visualized in cortex preparations by indirect immunofluorescence microscopy using antibodies to tubulin. The cortical array of microtubules is present in all oocytes before and for about 30 min after the application of 1-methyladenine, the hormone that induces oocyte maturation. The presence of microtubules was confirmed by electron microscopy. The microtubules in this array are depolymerized when oocytes are treated with colchicine or nocodozole and are augmented when oocytes are treated with taxol. Dihydrocytochalasin B treatment of the oocytes causes the microtubules to aggregate, presumably by altering a microfilament network also found in the cortex.

Both seastars broadcasted eggs and sperm in late spring and summer at various sites between 1973 and 1975. In Massachusetts, A. vulgaris spawned in June and A. forbesi spawned in July or August, while in Maine, A. vulgaris spawned in July. Reproduction (and growth) in these species is flexible, and depends on prey abundance. Dissection of ripe seastars over a range of sizes indicates that both species reach reproductive maturity at small size, between about 1 and 10 g. These results contrast to those obtained for the west coast seastar, Pisaster ochraceus , in which reproductive maturity is not attained until a size of 70-90 g wet weight, and in which organ cycles seem consistently inversely related.

PUBLICATION YEAR: 1985 LANGUAGE OF TEXT: English LANGUAGE OF SUMMARIES: English PUBLICATION TYPE: J (Journal-Article) ENVIRONMENTAL REGIME: M (Marine) ABSTRACT: Pisaster ochraceus were collected at Post Point, Bellingham, Washington, USA, in 1980. Total protease and tryptic specific activities were measured in pyloric caecal tissues and pyloric duct fluids of fed and starved individuals. Feeding resulted in increased levels of total protease and tryptic activities, and led to an increase in the ratio of total protease to tryptic specific activity in pyloric caecal tissue and a decrease in that ratio in pyloric duct fluid, indicating a release of trypsin into the duct with feeding. Trypsin activity showed little variability in fed seastars, but was quite variable in starving individuals. Total proteolytic activity, unlike that of tryptic activity, was always present in both fed and starved seastars. This may indicate a much broader role of generalized proteases in the cells of the pyloric caecum (e.g. as lysosomal enzymes of absorptive cells) in comparison to tryptic enzymes.

Radial nerve extracts of starfish induce maturation of both ovarian oocytes and follicle-free oocytes of sea cucumbers. The active factor from starfish radial nerve extracts appears to be peptides similar in molecular weight to starfish gonad-stimulating substance (GSS). It was concluded that starfish radial nerve extracts contain a substance(s) which induces maturation of sea cucumber follicle -free oocytes, and sea cucumber oocyte maturation is regulated by substances different from those in starfish.

The cycle of assembly-disassembly of cortical microtubules synchronized to the cycle of nuclear envelope breakdown and reformation and to the mitotic cycle; specifically, cortical microtubules are present when a nucleus is intact (germinal vesicle, female pronucleus, zygote nucleus, blastomere nucleus) and are absent whenever a meiotic or mitotic spindle is present. These findings are discussed in terms of microtuble organizing centers in eggs, possible triggers for microtubule assembly and disassembly, the eccentric location of the germinal vesicle, and the regulation of oocyte maturation and cell division.

As the archenteron begins to bend, the cells in the presumptive mouth region dissociate and migrate into the blastocoele where they become mesenchyme cells. This leaves a defect in the "blind" endodermal tube, which is covered by a basal lamina. Subsequently this exposed basal lamina bulges to form a blister which appears to extend across the blastocoele to make contact with spikelike projections from the future stomodeal region of the ectoderm.

Three major classes of actin-bearing lambda phage clones have been identified on the basis of restriction enzyme mapping and localization of actin coding regions. There are at most six non-allelic actin genes in the sea star genome. Southern blots of restriction enzyme-digested genomic DNA from individual sea stars probed with actin coding sequences indicate extensive polymorphism in actin gene regions. The locations of repetitive sequences within the genomic clones have been mapped. Approx. 1% of cDNA clones prepared from tube foot poly(A) RNA contain actin coding segments. The actin gene(s) from which the tube foot actin transcripts originate have been identified by hybridization with a 460 bp 3' untranslated region from one of the dDNA plasmids. Hybridization of the untranslated region probe with genomic digests demonstrates that there are at least three alleles for the tube foot actin in sea star populations.

Two types of nerve cells occur at regular intervals within the ciliary bands. Type I nerve cells are associated with the axonal tracts, and type II nerve cells, which are ciliated, occur along the edge of the ciliary bands. Two prominent ganglia, which appear as accumulations of nerve cells and neuropile, occur on the lower lip of the larval mouth. Smaller ganglia occur irregularly throughout the ciliary band. Organization of the nervous system and its association with effectors suggest it controls swimming and feeding. Several similarities exist between the nervous systems of larval asteroids, larval echinoids, and adult echinoderms.

Addition of bovine trypsin caused the rate of autoactivation to increase to an extent that is consistent with a system in which the autoactivation occurs in the presence of an inhibitor. An apparent association constant of 22.4 mL/mg was calculated for the binding of the inhibitor to bovine trypsin. The autoactivation process was found to occur after sequentially passing through filtration limits of 300,000 and 50,000 daltons. The evidence presented demonstrates that the activation process cannot be due to a membrane release phenomenon and is consistent with the model for a zymogen autoactivation process.

Cytoplasmic pH was measured by the DMO method, and concurrently, the initiation of maturation was determined by germinal vesicle breakdown (GVBD) and the increase in protein synthesis (percentage incorporation of amino acids). Results that (1) oocyte pH sub(1) rises slightly after initiation of maturation; (2) GVBD is not inhibited by acidifying pH sub(1); and (3) amino acid incorporation can be affected by large changes in pH sub(1), but not by the small pH sub(1) change promoted by maturation. Therefore, activation of GVBD and amino acid incorporation must proceed by mechanisms which do not include changing pH sub(1). These conclusions appear to be true of oocyte activation by fertilization as well, for the pH sub(1) change following insemination is even smaller than during maturation. These results are discussed in terms of mechanisms by which dormancy is controlled.

Adams) exhibits a shore -level size gradient with mean shell size increasing in a down-shore direction. Snails transferred to zones where they do not usually occur migrated back towards their original zone, thus re-establishing a size gradient and implying differential movement among size classes. Light inhibited upward, or caused downward, movement of large snails on vertical surfaces. Small snails were unaffected, ranging higher on illuminated vertical surfaces than large snails. Both sizes exhibited similar distributions in the dark. It is suggested that light is an important factor in the formation and maintenance of Tegula's shore-level size gradient. In response to water-borne chemicals derived from the sea star Pisaster ochraceus (Brandt), large snails moved up vertical surfaces in greater proportion than small. In response to contact with the predator, large snails moved away faster than small and individuals collected from crevices in the field moved away slower than those collected from open rock faces.

Parallel phase contrast, Nomarski and scanning electron microscopy (SEM) illustrate other changes brought about in sperm treated with the calcium ionophore A23187 and NH sub(4)Cl. A complete acrosome reaction is elicited by A23187, including exocytosis of the acrosomal vesicle and formation of a long acrosomal process which is filled with polymerized actin. Considerable actin polymerization is caused by NH sub(4)Cl, but the acrosomal vesicle is not exocytosed. The various patterns of NH sub(4)Cl -mediated polymerization of sperm actin always include bundles which project backward from the actomere and often others which project quite far forward in front of the acrosomal vesicle.

Single-copy super(125)I-DNA was prepared by hydroxyapatite chromatography after renaturation of randomly sheared genomic DNA to C sub(0)t 1000. Egg RNA was extracted by the guanidine-HCI method. The total amount of RNA per egg, 15 ng, was determined by three methods: spectrophotometrically, by isotopic dilution, and colorimetrically. The super(125)I-DNA tracer was hybridized with a large excess of RNA and the amount of DNA-RNA hybrids formed was assayed by hydroxyapatite. At termination of the reaction, which follows pseudo-first-order kinetics, 5.9% of the reactable single -copy DNA mass is present in DNA-RNA hybrids. Assuming asymmetric transcription, this represents 11.8% of the genomic single-copy complexity, or about 4.3 x 10 super(7) nucleotides of diverse sequence. Kinetic analyses indicate that on the order of 2-3% of the maternal RNA mass drives the hybridization reaction, and each single copy sequence is represented approximately 1.7 x 10 super(4) times per egg.

A total of 96,168 individuals belonging to 55 taxa were recorded in the quantitative survey; qualitative scrapings included 136 taxa. The protected outer coast intertidal assemblages were found at all but three stations along the shoreline. The upper midlittoral zone was typically dominated by Chthamalus dalli, C. fissus and Balanus glandula . The lower midlittoral was colonized either by Anthopleura elegantissima-Prionotis lanceolata facies along the outer breakwater or by A. elegantissima-Tetraclita squamosa rubescens facies along the inner breakwater. The mussel bed, which is the characteristic assemblage of the Californian lower midlittoral zone was obscured by the competitors P. lanceolata, T. squamosa rubescens and A. elegantissima , and was thinned out by predators, of which Pisaster ochraceus was the most voracious. Suspension feeders were dominant in the upper midlittoral and producers and grazes in the lower midlittoral. Predators were few in number and restricted to levels below mean lower low water. There was a gradual increase in numbers of intertidal species and individual abundance from level +5 ft (1.5m) to level +1 ft (0.3m) and from shoreline to outer breakwater.

Generally, all four species of gastropod demonstrate a weak to moderate avoidance response to the scent of such predatory seastars as Leptasterias hexactis and Pisaster ochraceus ; whereas direct contact with their soft parts elicits strong and often violent defensive behaviors characterized by shell twisting, propodial rearing which often leads to a loss of contact with the substrate, and somersaulting by metapodial thrusting.

Experimental addition of Pisaster ochraceus- in winter causes changes in the intertidal distribution of T. funebralis- similar to those observed during the summer increase in seastar numbers. It is suggested that these results supplant the hypothesis that lowered prereproductive mortality influences formation and maintenance of vertical size gradients in the lower intertidal zone.

Bending and segmentation of the exogastrulated archenteron with the formation of either single or double coelomic pouches follows the same schedule as the control. In addition, a region of the exogastrular ectoderm, which corresponds to the area of the mouth in controls, undergoes invagination. Early morphogenesis of the archenteron and invagination of the ectoderm during mouth formation appear to be intrinsic properties of these structures. At the time of mouth formation in the controls, a discrete region adjacent to the distal end of the exogastrulated archenteron becomes sticky. Examination of this region shows that the surfaces of the archenteron cells are relatively smooth and that processes of the mesenchyme cells extend between them. The evidence suggests that the mesenchyme cells are responsible for the stickiness, and that they may guide the archenteron and ectoderm into contact and maintain the contact during normal mouth formation.

No pedicellaria response was given in control seawater or when the sea star was downstream. The snail Tegula funebralis responded by moving up vertical surfaces when P. helianthoides or when Pisaster ochraceus were placed upstream. When these sea stars were introduced downstream, the snail's response was not significantly different from that in control seawater. Water collected from an aquarium containing a single sea star was sufficient to trigger the response of S. purpuratus and T. funebralis; the physical presence of the sea star was not essential. This indicated that a chemical stimulus was involved, and the lack of responses when sea stars were downstream argued strongly against the possible additional involvement of visual or vibrational stimuli. S. purpuratus gave stronger pedicellaria responses to water flowing over an active Pycnopodia helianthoides than to water flowing over the same sea star when it was inactive. The significance of the ability to distinguish between actively foraging and inactive predators is discussed, and a mechanism is proposed to explain differences in the amounts of stimulatory chemicals released by active and inactive sea stars.

M.californianus is found on some, but not all, sea mounts. Despite being one of the most characteristic invertebrates in the rocky intertidal zone, it is uncommon or absent in the subtidal area immediately adjacent to large land areas. Scuba dives off Tatoosh Island, Mukkaw Bay, Skagway Rocks, Spike Rock, Umatilla Reef and the north face of Cape Flattery failed to reveal mussel beds. On the other hand, mussels are abundant down to a depth of 24 m at Duncan and Duntze Rocks and were observed to occur to at least 37.5 m. Cover is solid on occupiable substrates at higher levels and diminishes rapidly at depths below 21 m. Pisaster ochraceus a predator of Mytilus in the intertidal zone occurs on Duncan and Duntze rocks but is uncommon. The biological structure, species composition and distribution pattern of these pinnacles is discussed.

The maximum pelagic periods in each class of echinoderms were approximately double other estimates based on cultured larvae. The pelagic periods in these cultures suggest a capacity for extensive dispersal in nature.

As in most asteroids, the paired coelomic pouches of P. ochraceus are formed from outpocketing of the archenteron. Arrays of 50 -angstrom- microfilaments are found in the presumptive coelomic pouch cells at the apex of the archenteron as well as in the filopodia of the mesenchyme cells. Both cell types undergo active movements throughout the entire process. Treatment of embryos with cytochalasin B (CCB) during coelomic pouch formation results in the loss of cell movements and the regression of the coelomic pouches; this is accompanied by the loss of microfilament arrays in both cell types. Cell movements and microfilament arrays reappear on removal of CCB and coelomic pouch formation resumes. Evidence suggests that the microfilaments in the presumptive coelomic pouch cells provide the main force for the outpocketing movement. The major role of the microfilament arrays in the filopodia of the mesenchyme cells associated with the coelomic pouches is to determine the definitive shape and location of the pouches.
