MIGRATION STOPOVERS AND THE CONSERVATION OF ARCTIC-BREEDING CALIDRIDINE SANDPIPERS

In addition to the energetic cost of transport, birds must find periodic stopovers to rest and refuel and, while there, cope with unfavorable weather, uncertainties of resource abundance and availability, intra- and interspecific competition, and predation pressures, all within the context of unfami...

Description
Summary:In addition to the energetic cost of transport, birds must find periodic stopovers to rest and refuel and, while there, cope with unfavorable weather, uncertainties of resource abundance and availability, intra- and interspecific competition, and predation pressures, all within the context of unfamiliar environments (Moore et al. 1995, 2005). Current threats to the ability of prairie wetland landscapes to provide adequate stopover resources for shorebirds over the next several decades include intensification of agriculture, with concomitant increasing rates of sedimentation and contaminant exposure, and the possibility of climate change with the predicted broad-scale loss of interior wetlands.
