Assessing habitat quality for conservation using an integrated occurrence‐mortality model
Summary Habitat suitability models are usually produced using species presence or habitat selection, without taking into account the demographic performance of the population considered. These models cannot distinguish between sink and source habitats, causing problems especially for species with lo...

Summary Habitat suitability models are usually produced using species presence or habitat selection, without taking into account the demographic performance of the population considered.
