Temperature and Prey Availability Drive Seasonal Variations in Diet, Abundance and Condition of <i>Forsterygion lapillum</i> Across Two Coastal Habitats. [PDF]

open access: yesEcol Evol
This study investigated how temperature, turbidity and prey availability affect the diet, body condition and abundance of F. lapillum in two coastal ecosystems. Results showed seasonal and spatial variation, with body condition, abundance and gut volume positively correlated with warmer temperatures but not with turbidity.

Validating COI eDNA Metabarcoding Primers for Detection of Subterranean Fauna. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Subterranean ecosystems host a diverse range of ancient fauna, but studying these ecosystems is challenging due to significant sampling difficulties. Environmental DNA (eDNA) metabarcoding offers a promising approach for monitoring subterranean biodiversity, yet issues such as primer bias and non‐target amplification can complicate its ...

Updated checklist and identification of areas of endemism of benthic amphipods (Caprellidea and Gammaridea) from offshore habitats in the SW Gulf of Mexico

open access: yesScientia Marina, 2006
An updated checklist of the benthic amphipods associated with soft bottoms in the SW Gulf of Mexico has been made and the areas of endemism have been identified. Amphipods were collected in a depth interval of 25 to 3700 m during six cruises from 1994 to

Amphipoda

open access: yes, 2020
Amphipoda abundances and diversity A total of 45,721 fauna individuals were counted (42 stations, 3 replicas, 126 samples), of which 2,122 individuals were amphipods (Amphilochidea and Senticaudata) (4.64 % of total macrofauna abundance). The Amphipoda were classified into 25 families and 52 species.
