Between the Poles: Rethinking Global Patterns in Sea Anemone Biodiversity

open access: yesJournal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim To assess global sampling coverage of sea anemones and global species richness across four different spatial resolutions, and analyse these along latitudinal gradients to investigate true bimodality and the extent to which these patterns have been influenced by uneven sampling efforts. Location The study encompasses a global scale.

Repeated hurricane disturbance has minimal impact on shallow coastal infaunal communities

open access: yesEcosphere, Volume 16, Issue 7, July 2025.
Abstract Disturbances are important drivers of seafloor community structure and diversity, especially in sediment infaunal communities with limited mobility. Shallow coastal sediment communities contribute to global nutrient cycling and carbon storage but also experience large‐scale disturbances, including storms.

Reconstructing SALMFamide neuropeptide precursor evolution in the phylum Echinodermata: ophiuroid and crinoid sequence data provide new insights

open access: yesFrontiers in Endocrinology, 2015
The SALMFamides are a family of neuropeptides that act as muscle relaxants in echinoderms. Analysis of genome/transcriptome sequence data from the sea urchin Strongylocentrotus purpuratus (Echinoidea), the sea cucumber Apostichopus japonicus ...

Regeneration in Stellate Echinoderms: Crinoidea, Asteroidea and Ophiuroidea

open access: yes, 2018
Reparative regeneration is defined as the replacement of lost adult body parts and is a phenomenon widespread yet highly variable among animals. This raises the question of which key cellular and molecular mechanisms have to be implemented in order to efficiently and correctly replace entire body parts in any animal. To address this question, different

Morphological diagnoses of higher taxa in Ophiuroidea (Echinodermata) in support of a new classification

open access: yesEuropean Journal of Taxonomy, 2018
A new classification of Ophiuroidea, considering family rank and above, is presented. The new family and superfamily taxa in O’Hara et al. (2017) were proposed to ensure a better readability of the new phylogeny but are unavailable under the provisions ...
