A nomenclature for echinoderm genes [PDF]

open access: yesDatabase, 2021
Abstract Echinoderm embryos and larvae are prominent experimental model systems for studying developmental mechanisms. High-quality, assembled, annotated genome sequences are now available for several echinoderm species, including representatives from most classes.

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

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 ...

Phylogeny of Echinoderm Hemoglobins [PDF]

open access: yesPLOS ONE, 2015
Recent genomic information has revealed that neuroglobin and cytoglobin are the two principal lineages of vertebrate hemoglobins, with the latter encompassing the familiar myoglobin and α-globin/β-globin tetramer hemoglobin, and several minor groups.

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 ...

A Review of Histocytological Events and Molecular Mechanisms Involved in Intestine Regeneration in Holothurians

open access: yesBiology, 2022
Most species of the class Holothuroidea are able to regenerate most of their internal organs following a typical evisceration process, which is a unique mechanism that allows sea cucumbers to survive in adverse environments.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A synthesis of the echinoderm fauna of the Maltese Islands [PDF]

open access: yes, 2006
A review of existing literature records of echinoderms from Malta and a study of a large collection of specimens was carried out between 2000 and 2004 so as to update and produce a validated checklist of echinoderms occurring in Maltese waters. Seventy

Possible Mechanisms of Stiffness Changes Induced by Stiffeners and Softeners in Catch Connective Tissue of Echinoderms

open access: yesMarine Drugs, 2023
The catch connective, or mutable collagenous, tissue of echinoderms changes its mechanical properties in response to stimulation. The body wall dermis of sea cucumbers is a typical catch connective tissue. The dermis assumes three mechanical states: soft,

Plated Cambrian bilaterians reveal the earliest stages of echinoderm evolution [PDF]

open access: yes, 2012
Echinoderms are unique in being pentaradiate, having diverged from the ancestral bilaterian body plan more radically than any other animal phylum. This transformation arises during ontogeny, as echinoderm larvae are initially bilateral, then pass through

Latin America Echinoderm Biodiversity and Biogeography: Patterns and Affinities [PDF]

open access: yes, 2012
We investigated the current patterns of diversity by country and by class of echinoderms, and analyzed their biogeographical, depth, and habitat or substratum affinities, using the database of the appendix of this book.
