Population changes in Czech passerines are predicted by their life-history and ecological traits

Abstract

The study used several life history and ecological traits to explain interspecific variability in long-term population trends in Czech passerines. Only two traits affected significantly the population trends: life-history continuum (species with slow strategies increased, species with fast strategies delcined) and dietary niche (insectivorous and omnivorous species increased, seed-eating species declined).
