Species composition, seasonal abundance and population structure of chaetognaths in Admiralty Bay (Antarctic)

open access: yesPolish Polar Research, 2016
Although chaetognaths inhabiting polar ecosystems are relatively well known, there are few reports on their functioning in the Antarctic coastal plankton community. The presented results provide the first comprehensive description of population structure

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.
