Tóm tắt

Over the last decades, many species have been forced to track their shifting climate envelopes, and at the same time man‐induced landscape fragmentation has led to the global decrease of natural habitat availability and connectivity. The interaction between these two co‐occurring global environmental changes might have very strong effects on biodiversity that are still understudied. Species‐specific responses to these environmental changes critically depend on individual dispersal, either to track suitable climatic conditions or to cope with landscape fragmentation. Here we study how dispersal in an ectotherm is affected by interactions between landscape fragmentation and weather conditions. We show that both the emigration rates out of suitable habitats and the topology of the trajectory of dispersing individuals were affected by temperature and landscape fragmentation. The emigration rate was temperature‐dependent in fragmented landscapes, with butterflies emigrating more at high temperatures. The emigration rate was temperature insensitive in more continuous landscapes. Move length was farther at low temperatures and less at high temperatures in fragmented landscapes. Move length was less at low temperatures and farther at high temperatures in more continuous landscapes. To our knowledge only two recent studies have documented patterns of interactions between climate and fragmentation, despite the fact that they are the two main drivers of biodiversity loss worldwide. Here, we go a step further by providing mechanistic explanations to such patterns.
