Using Light-Level Geolocation to Investigate the Carry-Over Effects of Long-Distance Migration on the Reproductive Success of Dunlin (Calidris Alpina Hudsonia)
Avian migration strategies can have lasting effects on individual fitness in subsequent seasons. These carry-over effects are difficult to study in migratory species because of the geographical separation between breeding and non-breeding sites. I used light-level geolocation to examine, for the fir...
