Butterfly species vary in sex‐specific sodium accumulation from larval diets

Ecological Entomology, Volume 50, Issue 1, Page 228-234, February 2025.
Male butterflies accumulate more sodium than females in three butterfly species, especially when larvae were exposed to high dietary sodium concentrations. Sodium bioaccumulation occurred mainly in Low Na treatments and bioexcretion was highest in females on High Na diets.

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

Ibis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...

Food web of a tropical high mountain stream: effects of nutrient addition [PDF]

, 2016
In order to define the effect of nutrient enrichment on trophic webs in an Andean mountain stream we performed an experiment using stable isotope ratios (δ15N and δ13C) to analyze different trophic compartments: 1) basal level: CPOM and biofilm; 2 ...

Feeding en route: Prey availability and traits influence prey selection by an avian predator on migration

Journal of Animal Ecology, Volume 93, Issue 9, Page 1176-1191, September 2024.
During fall migration, avivorous raptors and avian prey co‐occur across space and time. We used a novel approach—combining eDNA metabarcoding and eBird data—to investigate predator–prey interactions between an avivorous raptor and co‐occurring avian prey species. This approach revealed prey availability and traits influence raptor‐songbird interactions
