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.

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects
Animal Conservation, Volume 27, Issue 5, Page 722-735, October 2024.Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...

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
