Sperm ultra-structure and spermiogenesis in Syllis krohni (Polychaeta: Syllidae), with some observations on its reproductive biology

open access: yesScientia Marina, 2006
yllidae show a wide spectrum of both reproductive strategies and sperm types. Analysis of their reproductive patterns could drastically change the presently accepted taxonomic hierarchy of the group.

Spatio‐temporal patterns of eukaryotic biodiversity in shallow hard‐bottom communities from the West Antarctic Peninsula revealed by DNA metabarcoding

open access: yesDiversity and Distributions, Volume 29, Issue 7, Page 892-911, July 2023., 2023
Abstract Aim We studied molecular eukaryotic biodiversity patterns in shallow hard‐bottom Antarctic benthic communities using community DNA metabarcoding. Polar ecosystems are extremely exposed to climate change, and benthic macroinvertebrate communities have demonstrated rapid response to a range of natural and anthropogenic pressures.

Predicting diversity in benthic macro‐scale communities associated with mussel matrices in three Pacific ecoregions

open access: yesMarine Ecology, Volume 44, Issue 2, April 2023., 2023
Abstract Marine mussels are ubiquitous and their tough byssal threads allow for the formation of expansive, age‐aggregated mats known as mussel matrices which can host marine invertebrates and algal macro‐benthic communities playing an important role in food‐web dynamics.
