Providing evidence for the conservation of a rare forest butterfly: Results from a three-year capture-mark-recapture study

Basic and Applied Ecology, 2023
Species living in spatially structured populations require a network of interconnected habitat patches. Due to changes in forest management, this network of habitat patches has been lost for insect species inhabiting open spots within forests. We studied
