| Description: |
International audience ; Climate change is impacting global ecosystems, disrupting important ecosystem functions (Kerner et al. 2023). Climate change is especially dramatic in boreal and alpine systems, leading to upward migratory movements and threating local communities (Kerner et al. 2023; Chowdhury et al. 2025). Butterflies (Lepidoptera) are very vulnerable to climate change, since they respond strongly to climate, present clear phenological cycles with seasonal requirements (e.g., larval plant hosts, pupae refugia, adult nectaring sources), and tend to form specialized relationships with their host plants (Kerner et al. 2023; Chowdhury et al. 2025). In Europe, most Lepidoptera diversity and endemism are concentrated in alpine ecosystems (van Swaay et al. 2025), highlighting the threat of climate change. While multiple studies have assessed the direct effects of temperature on butterfly diversity (Kerner et al. 2023; Chowdhury et al. 2025), climate change effects are spatially variable, and act synergistically with landscape alterations (Kerner et al. 2023; Chowdhury et al. 2025). In our study, we evaluated how climate change, landscape dynamics, and geomorphological factors drive butterfly communities in the Eastern French Pyrenees. We assessed butterfly communities across 137 transects in the Eastern French Pyrenees between 2022 and 2025, and evaluated climate change and landscape dynamics from 1950s to 2020. We used localized climate models to assess climate change, and historic and current orthophotos to evaluate landscape dynamics. We observed significant afforestation in the Pyrenees with mounting treelines and forest densification, which may be associated to climate change but also with the loss of traditional farming practices. Such afforestation is leading to significant, and localized, changes on butterfly taxonomic, phylogenetic, and functional diversity. Areas with more afforestation show increased levels of diversity, in support with local upward migratory movements that may have high extinction ... |
