Differing drivers of decline within a migratory metapopulation has implications for future conservation
Abstract Researchers generally ascribe demographic drivers in a single sub‐population and presume they are representative. With this information, practitioners implement blanket conservation measures across metapopulations to reverse declines. However, such approaches may not be appropriate in circu...

Abstract Researchers generally ascribe demographic drivers in a single sub‐population and presume they are representative. With this information, practitioners implement blanket conservation measures across metapopulations to reverse declines. However, such approaches may not be appropriate in circumstances where sub‐populations are spatiotemporally segregated and exposed to different environmental variation. The Greenland White‐fronted Goose, Anser albifrons flavirostris, is an Arctic‐nesting migrant that largely comprises two sub‐populations (delineated by northerly and southerly breeding areas in west Greenland). The metapopulation has declined since 1999 but this trend is only mirrored in one sub‐population and the causes of this disparity are unclear. Here we compare the drivers and trends of productivity in both sub‐populations using population‐ and individual‐level analysis.
