Impacts of ocean warming on echinoderms: A meta‐analysis

open access: yesEcology and Evolution, 2023
Rising ocean temperatures are threatening marine species and populations worldwide, and ectothermic taxa are particularly vulnerable. Echinoderms are an ecologically important phylum of marine ectotherms and shifts in their population dynamics can have ...

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.

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

Genome-wide identification and comparative analysis of Dmrt genes in echinoderms

open access: yesScientific Reports, 2023
The Dmrt (Doublesex-mab3-related transcription factor) gene family is a class of crucial transcription factors characterized by one or several conserved DM (Doublesex/Mab-3) domains.

Advances in the Lower Ordovician of the western Iberian Chain, NE Spain [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The western Iberian Chain of NE Spain represents a lateral prolongation of the West Asturian-Leonese Zone. As other proximal sectors fringing NW Gondwana, the chain comprises a con­formable and continuous Furongian‒Tremadocian transition, comprising a

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.

The echinoderm adhesome

open access: yesDevelopmental Biology, 2006
Although the development of sea urchin embryos has been studied extensively and clearly involves both cell adhesion and cell migration, rather little is known about the adhesion receptors and extracellular matrix molecules involved. The completion of the genome of Strongylocentrotus purpuratus allows a comprehensive survey of the complement of cell ...

Phylogenomic analyses of Echinodermata support the sister groups of Asterozoa and Echinozoa.

open access: yesPLoS ONE, 2015
Echinoderms (sea urchins, sea stars, brittle stars, sea lilies and sea cucumbers) are a group of diverse organisms, second in number within deuterostome species to only the chordates. Echinoderms serve as excellent model systems for developmental biology

Ocean Acidification, but Not Environmental Contaminants, Affects Fertilization Success and Sperm Motility in the Sea Urchin Paracentrotus lividus

open access: yesJournal of Marine Science and Engineering, 2022
Ocean acidification poses an increasing concern for broadcast spawning species that release gametes in the water column where fertilization occurs. Indeed, the functionality of gametes and their interactions may be negatively affected by reduced pH ...
