Human impacts on the biodiversity of amphibians
Biodiversity loss is driven by the combined effects of different processes, such as habitat loss, climate change, pollution, and the spread of alien species. The conservation status of the world’s biodiversity keeps deteriorating and, within vertebrates, amphibians are the group showing both the largest proportion of threatened species and the highest rates of decline. Since the late ‘90s, we monitor amphibian populations across Italy to unravel the ecological factors related to distribution and abundance of different species, assess species’ temporal trends and their drivers, and study life-history and behavioural responses to new challenges delivered by human-mediated alterations of the environment.
