An evo-devo perspective on the regeneration patterns of continuous arm structures in stellate echinoderms

open access: yesThe European Zoological Journal, 2022
Regeneration is a post-embryonic developmental process common in Metazoa, which, despite obvious taxa-specific differences, can often share common principles and patterns.

Genogeographic clustering to identify cross‐species concordance of spatial genetic patterns

open access: yesDiversity and Distributions, Volume 28, Issue 4, Page 611-623, April 2022., 2022
Abstract Aim While in recent years, there have been considerable advances in discerning spatial genetic patterns within species, the task of identifying common patterns across species is still challenging. Approaches using new data from co‐sampled species permit rigorous statistical analysis but are often limited to a small number of species.

How does eDNA decay affect metabarcoding experiments?

open access: yesEnvironmental DNA, Volume 4, Issue 1, Page 108-116, January 2022., 2022
Ecological interpretations of eDNA metabarcoding data require an explicit understanding of eDNA decay across different study systems and species. Here, we used eDNA metabarcoding of water samples to examine eDNA decay in a wide variety of temperate marine metazoan species. We found the most substantial effects of eDNA decay on diversity occurred within

Sensitivity of a cold‐water coral reef to interannual variability in regional oceanography

open access: yesDiversity and Distributions, Volume 27, Issue 9, Page 1719-1731, September 2021., 2021
Abstract Aim We assessed the effects of regional oceanographic shifts on the macrofaunal biodiversity and biogeography of cold‐water coral reefs (CWCRs). CWCRs are often hotspots of biodiversity and ecosystem services and are in the frontline of exposure to multiple human pressures and climate change.

Deep-sea ophiuroids (Echinodermata: Ophiuroidea: Ophiurida) from the Gulf of Cadiz (NE Atlantic) [PDF]

open access: yes, 2011
The Ophiuroidea collected from mud volcanoes and adjacent bathyal environments from the Gulf of Cadiz are reviewed. Thirteen species from six families—Ophiacanthidae, Ophiactidae, Amphiuridae, Amphilepididae, Ophiuridae and Ophiolepididae— were ...

A new pathogen transmission mechanism in the ocean: the case of sea otter exposure to the land-parasite Toxoplasma gondii. [PDF]

open access: yes, 2013
Toxoplasma gondii is a land-derived parasite that infects humans and marine mammals. Infections are a significant cause of mortality for endangered southern sea otters (Enhydra lutris nereis), but the transmission mechanism is poorly understood.

Discovery of a second SALMFamide gene in the sea urchin Strongylocentrotus purpuratus reveals that L-type and F-type SALMFamide neuropeptides coexist in an echinoderm species [PDF]

open access: yes, 2010

Functional evolution of Ets in echinoderms with focus on the evolution of echinoderm larval skeletons [PDF]

open access: yes, 2010
Convergent evolution of echinoderm pluteus larva was examined from the standpoint of functional evolution of a transcription factor Ets1/2. In sea urchins, Ets1/2 plays a central role in the differentiation of larval skeletogenic mesenchyme cells.

Identification of Fine‐Scale Marine Benthic Ecoclines by Multiple Parallel Ordination

open access: yesJournal of Marine Sciences, Volume 2014, Issue 1, 2014., 2014
The species‐environment relationship is a fundamental structural property of natural ecosystems. Marine sedimentary macrofauna is known to be structured by a range of environmental variables; however, the mechanisms by which environmental variables covary to form complex‐gradients (i.e., groups of intercorrelated environmental variables), and how these
