The complete mitochondrial genome sequence of Stichopus variegatus (Echinodermata: Holothuroidea) and phylogenetic studies of Echinodermata

open access: yesMitochondrial DNA. Part B. Resources, 2019
At present, there exist some confusing issues on the species classification and phylogeny in Echinodermata. In this study, we first determined and described the complete mitochondrial genome of Stichopus variegatus. The complete mitogenome sequence had a

Los equinodermos (Cystoidea. Homalozoa. Stelleroidea. Crinoidea) del Paleozoico Inferior de los Montes de Toledo y Sierra Morena (España)

open access: yesEstudios Geologicos, 1984
Se confirma la presencia de los cistideos Codlocystis y Phlyctocystis en el Llandeilo de España, junto a un Diploporito indeterminado que quizá corresponda a un nuevo género.

The complete mitochondrial genome of the starfish Coscinasterias acutispina Stimpson, 1862 (Echinodermata, Forcipulatida) from the East China Sea

open access: yesMitochondrial DNA. Part B. Resources, 2022
In this study, we determined the first complete mitochondrial genome sequence of Coscinasterias acutispina Stimpson, 1862. The mitogenome was 16,186 bp in length and contained 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes ...

Fatty Acid-Rich Extract from Holothuria atra for Hyperuricemia via Expressions Modulation of GLUT9a and GLUT9b in Rat Model

open access: yesMolecules, 2023
An edible sea cucumber Holothuria atra has been hypothesized to have medicinal benefits against hyperuricemia owing to its bioactive compounds, including mono- and poly-unsaturated fatty acids. Herein, we aimed to investigate the fatty acids-rich extract

Estimation of growth parameters for the exploited sea cucumber Holothuria arguinensis from South Portugal [PDF]

open access: yes, 2018
Understanding how species grow is critical for choosing appropriate fisheries management strategies. Sea cucumbers shrink during periods of aestivation and have naturally flaccid bodies that make measuring growth difficult.

Filling the Silurian gap of solutan echinoderms with the description of new species of Dehmicystis from Spain

open access: yesActa Palaeontologica Polonica, 2023
Solutans were among the most enigmatic pre-radial and asymmetric echinoderms. A new species Dehmicystis ariasi sp. nov. is described from the upper part of the Llagarinos Formation, lower Ludlow (Silurian) of Northwest Spain.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Marine Flora and Fauna of the Northeastern United States Echinodermata: Crinoidea [PDF]

open access: yes, 1990
The crinoid fauna of the continental margin (0-1500 m) of northeastern North America (Georgia to Canada) includes 14 species in 13 genera and 5 families. We introduce the external morphology and natural history of crinoids and include a glossary of terms,

Complete mitochondrial genome analysis of Distolasterias nipon (Echinodermata, Asteroidea, Forcipulatida)

open access: yesMitochondrial DNA. Part B. Resources, 2018
In this study, we determined the complete mitochondrial genome sequences of Distolasterias nipon belonging to the class Asteroidea in the phylum Echinodermata. The complete mitogenome of D. nipon was 16,193 bp in length and consisted of 13 protein-coding
