Redox Metabolism During Aerial Exposure of the Sea Urchin Echinometra lucunter: An Ecophysiological Perspective

Animals
Intertidal organisms experience daily environmental fluctuations, including changes in temperature, UV radiation, and aerial exposure during low tide, requiring physiological strategies for survival.

Stars in the Silurian sky: Echinoderm holdfasts from the Carnic Alps [PDF]

, 2016
A small collection of echinoderm holdfasts from the Ludlow Cardiola Formation of the Carnic Alps (Austria) contains a wide range of morphologies as a response of environmental adaptation.

Meiofauna Biodiversity and Community Structures in the Barents Sea and Nansen Basin Are Influenced by Benthic Spatiotemporal Heterogeneity

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Benthic meiofauna in the Barents Sea were investigated for spatiotemporal variability and taxonomic composition. ABSTRACT Meiobenthic metazoans occur worldwide and are a cornerstone of aquatic ecosystems. Here, we investigate the composition of meiobenthic communities along a transect in the Barents Sea and Nansen Basin and provide the first ...

Developmental gene regulatory network architecture across 500 million years of echinoderm evolution [PDF]

, 2003
Evolutionary change in morphological features must depend on architectural reorganization of developmental gene regulatory networks (GRNs), just as true conservation of morphological features must imply retention of ancestral developmental GRN features ...

Potential Invasive Indo‐Pacific Acropora in a Coral Reef of Venezuela: A Contribution to Their Morphological and Molecular Knowledge

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.

Geographic Structure Without Co‐Divergence: Genomic Insights Into a Highly Specific Symbiosis Between Siphamia Cardinalfish and Their Bioluminescent Symbiont

Ecology and Evolution, Volume 16, Issue 3, March 2026.
In this study, three cardinalfish species in the genus Siphamia, S. tubifer, S. mossambica, and S. fuscolineata, from locations throughout the hosts' broad Indo‐Pacific distribution were analyzed for patterns of genetic divergence along with their luminous bacterial symbionts.

Bioinformatics analyses of the proteome of Holothuria tubulosa coelomic fluid and the first evidence of primary cilium in coelomocyte cells

Frontiers in Immunology
The holothurian immune system is characterized by complex defense mechanisms that act through humoral and cellular pathways. Coelomocites are the cellular component of coelomic fluid, and they are involved in host defense, stress response, wound healing,

An analysis of the meroplankton assemblages of Station L4 and the development and application of molecular techniques to aid taxonomic resolution. [PDF]

, 2012
Zooplankton data from the 1988-2007 Station L4 time-series were used to determine inter-and intra-annual patterns of meroplankton community change at Station L4, Plymouth, UK.

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Ultrafiltration and Fluid Excretion in Echinoids Involves the Axial Organ with Elimination via the Intestine

Life
Many animals display nephridial structures for the ultrafiltration of metabolic waste. However, a nephridial equivalent and an excretory system are not generally recognized for echinoderms.
