Sea star wasting disease demography and etiology in the brooding sea star Leptasterias spp. [PDF]
PLoS ONE, 2019 Sea star wasting disease (SSWD) describes a suite of disease signs believed to have led to catastrophic die-offs in many asteroid species, beginning in 2013. While most studies have focused on large, easily visible sea stars with widely-dispersing larvae,

Impact of the extinct megaherbivore Steller's sea cow (Hydrodamalis gigas) on kelp forest resilience
Frontiers in Ecology and Evolution, 2022 Giant kelp forests off the west coast of North America are maintained primarily by sea otter (Enhydra lutris) and sunflower sea star (Pycnopodia helianthoides) predation of sea urchins.

RNA expression and disease tolerance are associated with a “keystone mutation” in the ochre sea star Pisaster ochraceus [PDF]
PeerJ, 2017 An overdominant mutation in an intron of the elongation factor 1-α (EF1A) gene in the sea star Pisaster ochraceus has shown itself to mediate tolerance to “sea star wasting disease”, a pandemic that has significantly reduced sea star populations on the ...

Live imaging of echinoderm embryos to illuminate evo-devo
Frontiers in Cell and Developmental Biology, 2022 Echinoderm embryos have been model systems for cell and developmental biology for over 150 years, in good part because of their optical clarity. Discoveries that shaped our understanding of fertilization, cell division and cell differentiation were only ...

Evolution & Development, 2009 SUMMARY The genetic basis for the evolution of development includes genes that encode proteins expressed on the surfaces of sperm and eggs. Previous studies of the sperm acrosomal protein bindin have helped to characterize the adaptive evolution of gamete compatibility and speciation in sea urchins.

Sea stars generate downforce to stay attached to surfaces
Scientific Reports, 2021 Intertidal sea stars often function in environments with extreme hydrodynamic loads that can compromise their ability to remain attached to surfaces. While behavioral responses such as burrowing into sand or sheltering in rock crevices can help minimize ...
