Performance Variation In Leptasterias Spp. Among Populations And Habitats, Caleb Shaw, Laura Melroy, Janet Bair, Sarah Cohen Aug 2015

Performance Variation In Leptasterias Spp. Among Populations And Habitats, Caleb Shaw, Laura Melroy, Janet Bair, Sarah Cohen

STAR Program Research Presentations

Leptasterias spp. are six rayed sea stars that are found in rocky intertidal habitats ranging from the California coast to Alaska. In central California, Leptasterias spp. can be found in a variety of intertidal habitats in mixed populations. There are multiple clades that represent these populations and it is thought that they may vary behaviorally, including habitat preference. To investigate this individuals were collected from Pigeon Point, San Mateo, CA and characterized into two habitat categories according to where they were found: rocky habitat and pool habitat. To test for behavioral variation among habitats, righting response was used as a …
