Avian diversity changes in traditional agricultural landscapes of Japan over ten years

Agricultural intensification is a leading cause of biodiversity loss worldwide. However, the traditional agroecosystems are often associated with high avian diversity because of their landscape heterogeneity offering available niches to different bird species. Here, we focused on the temporal changes in taxonomic, functional, and phylogenetic diversity of avian communities from Satoyama traditional agricultural landscapes of Japan. We found significant temporal trends (e.g., increasing) in overall species richness, forest specialist species richness, phylogenetic diversity and phylogenetic relatedness within avian assemblages, regardless of the land use composition surrounding the sites. The simultaneous increase in species richness and phylogenetic relatedness could highlight a process of biotic homogenization, typical of anthropized environments. Avian diversity was also significantly affected by the proportion of water bodies (e.g., increasing functional richness and dispersion, but ..., , # Avian diversity changes in traditional agricultural landscapes of Japan over ten years
