Maintaining ecosystem resilience: functional responses of tree cavity nesters to logging in temperate forests of the Americas

Abstract Logging often reduces taxonomic diversity in forest communities, but little is known about how this biodiversity loss affects the resilience of ecosystem functions. We examined how partial logging and clearcutting of temperate forests influenced functional diversity of birds that nest in tr...
