Integrating Causal and Evolutionary Analysis of Life-History Evolution: Arrival Date in a Long-Distant Migrant
In migratory species, the timing of arrival at the breeding grounds is a life-history trait with major fitness consequences.The optimal arrival date varies from year-to-year, and animals use cues to adjust their arrival dates to match this annual variation.However, which cues they use to time their arrival and whether these cues actually predict th
