A chain is as strong as its weakest link: assessing the consequences of habitat loss and degradation in a long-distance migratory shorebird
The conservation of migratory species represents a major challenge, as they use multiple sites, all contributing in varying degrees in sustaining high survival and reproductive success. There is particular concern for shorebirds of the East Asian—Australasian Flyway (EAAF), where declining numbers o...

The conservation of migratory species represents a major challenge, as they use multiple sites, all contributing in varying degrees in sustaining high survival and reproductive success.
