Genomic Divergence of Sympatric Lineages Within Stichopus cf. horrens (Echinodermata: Stichopodidae): Insights on Reproductive Isolation Inferred From SNP Markers [PDF]

open access: yesEcology and Evolution
How reproductive barriers arise in early stages of divergence among broadcast spawning organisms that exist in sympatry remains poorly understood. Reproductively isolated lineages (Clade A and B) of Stichopus cf.

Phylotranscriptomic analysis uncovers a wealth of tissue inhibitor of metalloproteinases variants in echinoderms [PDF]

open access: yesRoyal Society Open Science, 2015
Tissue inhibitors of metalloproteinases (TIMPs) help regulate the extracellular matrix (ECM) in animals, mostly by inhibiting matrix metalloproteinases (MMPs). They are important activators of mutable collagenous tissue (MCT), which have been extensively

Echinoderm Lagerstätten from high-latitude Gondwana – filling the gap in the Ordovician diversification of the phylum [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The phylum Echinodermata is a major component of marine ecosystems since the first appearance of echinoderms in the Cambrian. Like other metazoan phyla, echinoderms underwent two major evolutionary pulses in early Palaeozoic times: the Cambrian Explosion

Complete mitochondrial genome of Henricia pachyderma (Asteroidea, Spinulosida, Echinasteridae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
Next-generation sequencing was used to obtain the complete mitogenome of Henricia pachyderma (Hayashi, ). The mitogenome form was found to be a circular molecule 16,192 bp long with a 57.1% AT bias. Gene arrangement and composition of H.
