Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras
Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Invasive species invoke a lifetime of trophic change in native stream fishes
Ecosphere, Volume 16, Issue 6, June 2025.Abstract Trophic interactions operate across the lifetime of an individual organism, yet our understanding of these processes is largely limited to a single life stage or moment in time. Management and conservation implications of this knowledge gap are particularly important, given the mounting number, spread, and ecological impacts of invasive ...
