The measurement of naturally occurring stable isotope ratios of the light elements (C, N, H,
O, S) in animal tissues and associated organic and inorganic fractions of associated …

Accounting for migration and connectivity of mobile species across the annual cycle can
present challenges for conservation and management efforts. The use of stable isotope …

Winter habitat quality can influence breeding phenology and reproductive success of
migratory birds. Using stable isotope ratios of carbon (δ13C) from bird claws and red blood …

Context Maps of C3 and C4 plant abundance and stable carbon isotope values (δ13C)
across terrestrial landscapes are valuable tools in ecology to investigate species distribution …

Background Vector-borne diseases like West Nile virus (WNV) pose a global health
challenge, with rising incidence and distribution. Culex mosquitoes are crucial WNV vectors …

Previous studies have linked winter habitat with subsequent breeding phenology and
physical condition of migratory birds, but few have found delayed effects of winter habitat on …

Conservation efforts directed at population declines for migratory animals must consider
threats occurring at different stages often separated by vast distances. Furthermore …

Carry-over effects from one stage of the annual cycle to subsequent stages can have
profound effects on individual fitness. In migratory birds, much research has been devoted to …

Migratory birds usually respond to climate change by modifying breeding and/or wintering
areas, as well as by reproducing earlier. In addition, changes in winter habitat use or …

Recently, population declines have been reported for many migratory birds. Because of
complex life cycles, determining the causes for such declines is often difficult. Thus …
