Zinc Sunscreens Affect Development of Strongylocentrotus purpuratus Embryos
… development of California purple sea urchin, <em>Strongylocentrotus purpuratus</em>. Embryos developed in various concentrations of Zn, the sources of which included zinc-containing compounds: ZnO and ZnSO<sub>4</sub>; and ZnO sunscreens: All Good, Badger, and Raw Elements. ZnO sunscreens were …

Effects of Bisphenol-A and Styrene on Fertilization and Development of the Purple Sea Urchin (Strongylocentrotus purpuratus)
… relevant concentrations. Purple sea urchins, <em>Strongylocentrotus purpuratus,</em> from the central coast of California, were utilized to examine effects of BPA and styrene on fertilization success and early development of resulting embryos. Previous research has demonstrated that BPA and …

Comparative analysis of the promoters of the CyI-CyIIa-CyIIb actin gene cluster in the sea urchin Strongylocentrotus purpuratus
Three of the eight actin genes in the sea urchin Strongylocentrotus purpuratus were used for a comparative analysis. The cytoplasmic actin genes CyI, CyIIb and CyIIa are linked in the genome and encode very similar proteins. However, their spatial and temporal expression patterns are differentially …

Effects of ocean acidification combined with multiple stressors on early life stages of the pacific purple sea urchin
… life stages of the Pacific purple sea urchin, Strongylocentrotus purpuratus. Research has suggested that multiple stressors could exacerbate, cancel, or even alleviate the impacts of ocean acidification on echinoderms. This study assessed the combined effects of changes in pCO2 concentrations …

Gut Patterning In Development And Evolution: A Comparative Differential Transcriptomics Approach
… in two echinoderm species, the sea urchin Strongylocentrotus purpuratus and the sea star Patiria miniata, has been studied with the purpose of acquiring further knowledge on the process of gut patterning in the sea urchin larva and to compare it with the sea star embryo, focusing on the …

Ingestion Rates of Five Species of Pacific Northwest Echinoderm Larvae on Natural and Artificial Particles
… and Evasterias troschelii, the sea urchin Strongylocentrotus purpuratus, and the sand dollar Dendraster excentricus, were investigated by assigning larvae to three natural and one artificial diet in the laboratory. The natural algal diets included Dunaliella tertiolecta, Isochrysis galbana …

Phylogenomics of vertebrate serpins
… of serpins from Nematostella vectensis, Strongylocentrotus purpuratus, Ciona intestinalis, four fish species, frog, chicken and mammals were investigated, using gene architecture analyses and stringent criteria for identification of orthologs. With some deviations, all vertebrate serpin …
