Starfish (Asteroidea) is one of the biota that make up Bilik Beach, Baluran National Park. The aim research was to determine diversity starfish species in intertidal zone Park, Situbondo Regency, East Java. method used survey method. Data collection carried out by site surveys, determining locations, sampling, observing, and identifying species. Sampling when seawater reached its maximum ebb. l...

We describe an easy and simple way to immobilize the ascending aorta with the Starfish heart positioner during proximal anastomosis in off-pump coronary artery bypass grafting.

Our study focused on the precise reproductive behavior of the starfish Leptasterias polaris (Muller and Troschel) before and during spawning--a subject of much speculation and evident ecological importance. Between the third week of December 1992 and mid-January 1993, we observed spawning in the laboratory that roughly corresponded to field observations in the Lower St. Lawrence Estuary. In exp...

Outbreaks of crown-of-thorns starfish are often attributed to step-changes in larval survivorship following anomalous increases in nutrients and food availability. However, larval growth and development is also influenced by the nutritional condition of spawning females, such that maternal provisioning may offset limitations imposed by limited access to exogenous sources of nutrients during the...

Molluscan pedal peptides (PPs) and arthropod orcokinins (OKs) are prototypes of a family of neuropeptides that have been identified in several phyla. Recently, starfish myorelaxant peptide (SMP) was identified as a PP/OK-type neuropeptide in the starfish Patiria pectinifera (phylum Echinodermata). Furthermore, analysis of transcriptome sequence data from the starfish Asterias rubens revealed tw...

The paper proposed that predation, especially that which prevented spatial monopolization by a competitively dominant species, maintained or enhanced local species diversity. The viewpoint was supported by a controlled field experiment involving starfish removal, and observed subsequent decline in community species richness. [The SCI indicates that this paper has been cited over 275 times since...

Pedal peptide (PP) and orcokinin (OK) are related neuropeptides that were discovered in protostomian invertebrates (mollusks, arthropods). However, analysis of genome/transcriptome sequence data has revealed that PP/OK-type neuropeptides also occur in a deuterostomian phylum-the echinoderms. Furthermore, a PP/OK-type neuropeptide (starfish myorelaxant peptide, SMP) was recently identified as a ...

Sporadic outbreaks of the coral-eating crown-of-thorns starfish are likely to be due, at least in part, to spatial and temporal variation in reproductive and settlement success. For gonochoric and broadcast spawning species such as crown-of-thorns starfish, spawning synchrony is fundamental for achieving high rates of fertilization. Highly synchronized gamete release within and among distinct p...
