Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

Journal of Animal Ecology, EarlyView.
Using a spatially explicit model parameterized with GPS telemetry, we show that migratory and resident red deer play distinct roles in nitrogen redistribution across alpine landscapes. Migrants uniquely transport nitrogen upslope and up elevation, linking ecosystem element pools and revealing how the loss of migration alters large‐scale ecosystem ...
