Dietary Differentiation Between Sympatric Ecotypes of Astatotilapia calliptera From Lake Masoko (Kisiba), Tanzania Revealed by Metabarcoding

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Differentiation between sympatric Astatotilapia calliptera ecotypes using dietary metabarcoding reveal presence of resource partitioning. ABSTRACT Sympatric speciation is defined as the formation of new species in the absence of geographic barriers, but the genomic and life history strategy mechanisms underpinning sympatric speciation are still far ...

Bulk and amino acid isotope evidence of supplementary food sources besides euphotic production for a deep-sea coral community in the South China Sea

open access: yesFrontiers in Marine Science
Deep-sea coral communities, rich in various zoobenthos, have been discovered in the South China Sea (SCS) in recent years. Yet little is known about the trophic structure of these communities.

Another Novel Feeding Mode in the Labridae: Juvenile Tuskfish Fan Sand With Vigorous Single Pectoral Fin Swipes

open access: yesMarine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Fishes exhibit a range of feeding modes and strategies to forage in and on sand habitat. Here, we describe a novel feeding mode, whereby small juvenile baldchin groper, Choerodon rubescens (⁓65–100 mm TL), vigorously forward sweeps the benthos with a single pectoral fin to reveal small benthic prey and visually scans the immediate benthos on ...

Animal movement in space and time: the role of thermal barriers and individual variation in modulating predator–prey overlap in stratified lakes

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Animal movements play a crucial role in ecosystem dynamics, regulating numerous functions from nutrient cycling to habitat coupling. Therefore, any factor modulating animal behavior (e.g. physiology and individual preferences in habitat choice) has the potential to influence ecosystem functioning.
