Identifying the demographic pathways linking environmental covariates to population dynamics in an avian migrant. [PDF]

open access: yesEcol Appl
Abstract Understanding and predicting the effects of climate change on populations requires linking the environmental conditions to demographic rates and the demographic rates to population‐level consequences, but often this complete demographic pathway is not studied.
