Site‐level connectivity identified from multiple sources of movement data to in...
Beal, Martin; Nightingale, Josh; Belo, João R.; Batey, Chris; Belting, Heinrich; Bocher, Pierrick; Burgess, Malcolm; Craft, Taylor B.; Crockford, NicolaMigratory birds depend on a suite of sites across their annual cycles, making them vulnerable to a wide variety of anthropogenic pressures. Current area-based conservation measures have been found inadequate to safeguard migratory birds, in part due to a lack of consideration for the connectivity between sites mediated by the movements of individuals. To address this issue, we develop a network analysis integra...
Seasonal Variation in the Diet of Migratory Shorebirds Wintering in the Bijagós...
Coelho, Ana P.; Lopes, Paula; Rocha, Afonso D.; Barros, Aissa R. de; Piersma, Theunis; Alves, José A.As on intertidal flats across the globe, the migratory shorebirds that spend most of their annual cycle in the Bijagós Archipelago, Guinea-Bissau, feed on macro zoobenthic prey buried in the intertidal soft sediments. Understanding the diet of shorebirds throughout the period of residence in the Bijagós can help to under stand the degree of their trophic flexibility. In this study, we first reconstruct the diet...
High Migratory Survival and Highly Variable Migratory Behavior in Black-Tailed ...
Senner, Nathan R.; Verhoeven, Mo A.; Abad-Gómez, José M.; Alves, José A.; Hooijmeijer, Jos C. E. W.; Howison, Ruth A.; Kentie, RosemarieFew 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 migration is to affect the population dynamics ofmigratory species and how capablemigrantsmay be of responding to changing environmental conditions within their li...
