Using change trajectories to study the impacts of multi-annual habitat loss on fledgling production in an old forest specialist bird

Abstract The loss and subdivision of habitat into smaller and more spatially isolated units due to human actions has been shown to adversely affect species worldwide. We examined how changes in old forest cover during eight years were associated with the cumulative number of fledged offspring at the...
