Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
, 1987 The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Limnology 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 ...

Methods 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.

A systematic account of the chaetognatha of the Indian coastal waters, with observations on their seasonal fluctuations along the Malabar Coast. [PDF]
, 1952 Material for this investigation was collected mainly from the triweekly plankton hauls from the foreshore and offshore waters, off West Hill, three miles north of Calicut in the Malabar District along the West Coast of India (750 46' E. and 110 17' N.)

Environmental DNA, Volume 7, Issue 5, September–October 2025.We assess the resolution of eDNA metabarcoding for detecting rocky intertidal taxa across three spatial scales—national, regional, and local. Distinct eDNA signals were observed at each scale, with community differences more pronounced at broader scales.
