Spatial vision in the purple sea urchin Strongylocentrotus purpuratus (Echinoidea).
Recent evidence that echinoids of the genus Echinometra have moderate visual acuity that appears to be mediated by their spines screening off-axis light suggests that the urchin Strongylocentrotus purpuratus, with its higher spine density, may have even more acute spatial vision. We analyzed the movements of 39 specimens of S. purpuratus after they were placed in the center of a featureless tan...
متن کاملSeasonal variation in the effects of food availability on gametogenesis in the purple urchin (Strongylocentrotus purpuratus)
The amount of food and when it is available affect both the timing of reproduction and the number of gametes produced by purple sea urchins, Strongylocentrotus purpuratus. To investigate this further, the effects of food availability on feeding rates, gonad growth, and gamete development were examined in S. purpuratus collected from the Point Loma kelp forest near San Diego, California, USA (32...
متن کاملExposure to ultraviolet radiation causes proteomic changes in embryos of the purple sea urchin, Strongylocentrotus purpuratus
We performed experiments to determine how environmentally relevant ultraviolet radiation (UVR) affects protein expression during early development in the sea urchin, Strongylocentrotus purpuratus. To model the protein-mediated cell cycle response to UV-irradiation, six batches of embryos were exposed to UVR, monitored for both delays in the first mitotic division and changes in the proteome at ...
متن کاملOcean acidification research in the 'post-genomic' era: Roadmaps from the purple sea urchin Strongylocentrotus purpuratus.
Advances in nucleic acid sequencing technology are removing obstacles that historically prevented use of genomics within ocean change biology. As one of the first marine calcifiers to have its genome sequenced, purple sea urchins (Strongylocentrotus purpuratus) have been the subject of early research exploring genomic responses to ocean acidification, work that points to future experiments and ...
متن کاملRevised estimates of the effects of turbulence on fertilization in the purple sea urchin, Strongylocentrotus purpuratus.
Turbulent water motion can either aid or hinder external fertilization in aquatic organisms. On one hand, turbulence provides the mixing necessary to bring eggs and sperm together; on the other, the forces imposed by turbulent eddies may interfere with the attachment of sperm to eggs and may even damage zygotes. Mead and Denny (1) explored this dichotomy by measuring the efficacy of fertilizati...
