– Many shorebirds are Nearctic-Neotropical migrants that move from their northern breeding grounds to wintering areas in Central and South America. Shorebirds differ from many other groups of avian migrants by their extremely long and demanding flights, gregariousness, restriction to limited numbers of sites, long lifespans, and low recruitment. Migration monitoring data suggest that population...

Habitat loss and disease are main drivers of global amphibian declines, yet the interaction between them remains largely unexplored. Here we show that paradoxically, habitat loss is negatively associated with occurrence, prevalence, and infection intensity of the chytrid fungus Batrachochytrium dendrobatidis (Bd) in amphibian populations in the tropics. At a large spatial scale, increased habit...
