Echinoderm immunity [PDF]

open access: yesInvertebrate Survival Journal, 2010
Echinoderms are exclusively marine animals that, after the chordates, represent the second largest group of deuterostomes. Their diverse species composition and singular ecological niches provide at the same time challenges and rewards when studying the ...

Environmental Drivers of Mesophotic Echinoderm Assemblages of the Southeastern Pacific Ocean [PDF]

open access: yesFrontiers in Marine Science, 2021
Mesophotic ecosystems (50–400 m depth) of the southeastern Pacific have rarely been studied because of the logistical challenges in sampling across this remote zone. This study assessed how oxygen concentrations and other environmental predictors explain

Antero-posterior patterning in the brittle star Amphipholis squamata and the evolution of echinoderm body plans [PDF]

open access: yesEvoDevo
Although the adult pentaradial body plan of echinoderms evolved from a bilateral ancestor, identifying axial homologies between the morphologically divergent echinoderms and their bilaterian relatives has been an enduring problem in zoology.

Live imaging of echinoderm embryos to illuminate evo-devo

open access: yesFrontiers 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 ...

The RNA Virome of Echinoderms [PDF]

open access: yesJournal of General Virology, 2022
Abstract Echinoderms are a phylum of marine invertebrates that include model organisms, keystone species, and animals commercially harvested for seafood. Despite their scientific, ecological, and economic importance, there is little known about the diversity of RNA viruses that infect echinoderms compared to other ...

Large-scale spatial distribution patterns of echinoderms in nearshore rocky habitats. [PDF]

open access: yesPLoS ONE, 2010
This study examined echinoderm assemblages from nearshore rocky habitats for large-scale distribution patterns with specific emphasis on identifying latitudinal trends and large regional hotspots.

Thyroid hormone membrane receptor binding and transcriptional regulation in the sea urchin Strongylocentrotus purpuratus

open access: yesFrontiers in Endocrinology, 2023
Thyroid hormones (THs) are small amino acid derived signaling molecules with broad physiological and developmental functions in animals. Specifically, their function in metamorphic development, ion regulation, angiogenesis and many others have been ...

Effect of Enriched Substrate on the Growth of the Sea Cucumber Holothuria arguinensis Koehler and Vaney, 1906 Juveniles

open access: yesDiversity, 2023
The sea cucumber Holothuria arguinensis (Koehler and Vaney, 1906) presents an increasing commercial value in Asian markets and its exportation depends exclusively on wild stock harvesting.

Symbiotic Life of Echinoderm Larvae

open access: yesFrontiers in Ecology and Evolution, 2020
Echinoderm larvae have served as a fundamental system for understanding development and life history evolution over much of the last century. In the last few decades, our understanding of echinoderm larvae has expanded to the microbiota that they ...

Gene regulation of adult skeletogenesis in starfish and modifications during gene network co-option

open access: yesScientific Reports, 2021
The larval skeleton of the echinoderm is believed to have been acquired through co-option of a pre-existing gene regulatory network (GRN); that is, the mechanism for adult skeleton formation in the echinoderm was deployed in early embryogenesis during ...
