Impacts of habitat loss on migratory shorebird populations and communities at stopover sites in the Yellow Sea

Chi-Yeung (Jimmy) Choi is an applied ecologist with expertise in animal ecology, conservation biology, wetland ecology and environmental management. He studies the relationship between animals and their environment. Current study systems include the ecology of migratory birds, with a focus on their foraging and movement ecology within and between coastal intertidal wetlands. This requires extensive fieldwork in many places ranging from Alaska and East Asia to Australia and New Zealand. The work has led to investigations of diet, habitat use, local movement, population dynamics as well as migration phenology and strategies, often using the latest technology in wildlife tracking and remote sensing. Based on the findings from these studies, long-term habitat quality monitoring, protected area boundary adjustment and integrated natural and artificial management are proposed to improve the habitats for migratory waterbirds. These efforts not only contribute to nature conservation, but also to the restoration of wetland ecosystems on which humans depend.
