Effect of land use, habitat suitability, and hurricanes on the population connectivity of an endemic insular bat

Abstract Urbanization and natural disasters can disrupt landscape connectivity, effectively isolating populations and increasing the risk of local extirpation particularly in island systems. To understand how fragmentation affects corridors among forested areas, we used circuit theory to model the l...
