The effects of temperature on nest predation by mammals, birds, and snakes

摘要: Abstract. Understanding how weather influences survival and reproduction is an important component of forecasting climate change will influence wildlife population viability. Nest predation the primary source reproductive failure for passerine birds can in response to temperature. However, it unclear which predator species are responsible such patterns because events rarely observed. We investigated whether temperature influenced predator-specific rates nest by analyzing data from six prior studies conducted between 1997 2010 Texas, Illinois, Missouri that used constant-surveillance video systems identify predators at nests Golden-cheeked Warblers (Setophaga chrysoparia), Blackcapped Vireos (Vireo atricapilla), Indigo Buntings (Passerina cyanea), Acadian Flycatchers (Empidonax virescens). Rates snakes increased as daily maximum temperatures increased, whereas mammals was essentially ...
