Delineating ecologically distinct groups for annual cycle management of a declining shorebird
Journal of Applied Ecology, Volume 62, Issue 5, Page 1152-1165, May 2025.Using measurements of migratory connectivity in concert with expert opinion can define ecologically distinct groups for wildlife management that differ in the environmental conditions they experience across seasons of the annual cycle, which is a key component for understanding and reversing declines of migratory species. Abstract Patterns of migratory

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

La construcción social de la ruta migratoria en la frontera tabasqueña
REVISTA TRACEThis article analyzes migratory routes, not only as the sum of trajectories between two geographical points, rather as a process that involves the construction of social spaces through the mobility, hope and settlement of the migrants. We argue that migratory routes are constructed through widely diverse groups of people involved, such as the migrants,
