Genetic variation in the brooding brittle-star: a global hybrid polyploid complex? [PDF]

open access: yesRoyal Society Open Science
The widespread and abundant brooding brittle-star (Amphipholis squamata) is a simultaneous hermaphrodite with a complex mitochondrial phylogeography of multiple divergent overlapping mtDNA lineages, high levels of inbreeding or clonality and unusual ...

Antero-posterior patterning in the brittle star Amphipholis squamata and the evolution of echinoderm body plans [PDF]

open access: yesEvoDevo
Although the adult pentaradial body plan of echinoderms evolved from a bilateral ancestor, identifying axial homologies between the morphologically divergent echinoderms and their bilaterian relatives has been an enduring problem in zoology.

Comparison of the complete mitochondrial genome of Phyllophorus liuwutiensis (Echinodermata: Holothuroidea: Phyllophoridae) to that of other sea cucumbers. [PDF]

open access: yesFEBS Open Bio, 2020
In this paper, we analyzed the mitochondrial genome of Phyllophorus liuwutiensis. We examined genome composition, base composition, codon usage of protein‐coding genes and gene arrangement. In addition, we compared the gene arrangements of six echinoderms, revealing that the gene order of P. liuwutiensis was a new arrangement.

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 ...
