High Migratory Survival and Highly Variable Migratory Behavior in Black-Tailed Godwits

Senner, Nathan R.; Verhoeven, Mo A.; Abad-Gómez, José M.; Alves, Jose; Hooijmeijer, Jos Corstiaan Elbert Wouter; Howison, Ruth A.; Kentie, Rosemarie; Loonstra, A. H.Jelle; Masero, Jose A.; Rocha, Afonso D.; Stager, Maria; Piersma, Theunis (Frontiers Media SA, 2019-04-09)

Few studies have been able to directly measure the seasonal survival rates of migratory species or determine how variable the timing of migration is within individuals and across populations over multiple years. As such, it remains unclear how likely ...
Why Are Whimbrels Not Advancing Their Arrival Dates Into Iceland? Exploring Seasonal and Sex-Specific Variation in Consistency of Individual Timing During the Annual Cycle

Carneiro, Camilo; Gunnarsson, Tomas Gretar; Alves, Jose (Frontiers Media SA, 2019-07-02)

The timing of annual events is key for organisms that exploit seasonal resources, as deviations from optimal timing might result in considerable fitness costs. Under strong time selection, individuals likely have fewer suitable strategies available ...
