We review progress in our understanding of the importance of waterbirds as dispersal
vectors of other organisms, and identify priorities for further research. Waterbirds are …

Estimates of population size serve a number of important purposes for species'
conservation. For shorebirds, criteria based on proportions of a given population are used to …

It is now some five years since the publication of the first compilation of all available
information to assess population sizes of all shorebirds in North America (Morrison et al …

Body condition (ie relative mass after correcting for structural size) affects the behaviour of
migrating birds, but how body condition affects migratory performance, timing and fitness is …

Abstract Each May, red knots (Calidris canutus rufa) congregate in Delaware Bay during
their northward migration to feed on horseshoe crab eggs (Limulus polyphemus) and refuel …

Understanding how events during one period of the annual cycle carry over to affect survival
and other fitness components in other periods is essential to understanding migratory bird …

Summary 1 Millions of shorebirds migrate each year through a small number of highly
productive staging areas where they often conflict with fisheries interests. Delaware Bay …

Understanding the biology, constraints of migration, and the yearly movement patterns of
birds is essential to conserving them, particularly in the case of long-distant migrant …

Most migratory shorebird species are declining, some are endangered, and some may be
vulnerable to contaminants on long distance travel between wintering grounds and high …

These 15th Proceedings provide an overview of the ongoing research and management
activities on polar bears in the circumpolar Arctic. Together with the previous 14 …
