Species richness and distribution patterns of echinoderms in the southwestern Atlantic Ocean (34-56°S) [PDF]

open access: yesScientia Marina, 2014
The aim of this study was to compile and analyse available historical information on echinoderms in the southwestern Atlantic Ocean in order to make a synthesis of present taxonomical knowledge, to identify patterns of geographical distribution of ...

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.

Genome-wide identification and spatiotemporal expression analysis of cadherin superfamily members in echinoderms [PDF]

open access: yesEvoDevo, 2023
Background Cadherins are calcium-dependent transmembrane cell–cell adhesion proteins that are essential for metazoan development. They consist of three subfamilies: classical cadherins, which bind catenin, protocadherins, which contain 6–7 calcium ...

Environmental Drivers of Mesophotic Echinoderm Assemblages of the Southeastern Pacific Ocean

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

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.

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 ...

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 ...

Draft Genome of the Sea Cucumber Holothuria glaberrima, a Model for the Study of Regeneration

open access: yesFrontiers in Marine Science, 2021
Regeneration is one of the most fascinating and yet least understood biological processes. Echinoderms, one of the closest related invertebrate groups to humans, can contribute to our understanding of the genetic basis of regenerative processes.

Historical aspects of meetings, publication series, and digital resources dedicated to echinoderms

open access: yesZoosystematics and Evolution, 2014
Half a century after the first scientific meeting dedicated to marine spiny-skinned animals (Deuterostomia: Echinodermata) was held in Washington, DC, we take this opportunity to provide information on a number of historical aspects related to the ...
