Interactions between landscape structure and bird mobility traits affect the connectivity of agroecosystem networks

Enhancing functional connectivity is key to achieving a sustainable agroecosystem. There has been an increase in using connectivity metrics to understand how spatial heterogeneity affects dispersal, yet most studies have been single-species focused. Variability in species’ ecological traits, such as...
