- Description
- Human modification of natural landscapes is a key threatening process contributing to the decline of global biodiversity. Amphibians are particularly vulnerable to this threat, with over a third of species threatened as a direct result. However, some habitat modifications may be less detrimental than others, with some species known to successfully thrive in certain artificial habitats while others undergo further declines. Yet, recognizing how amphibians respond to different habitat modifications remains limited, particularly on a global scale. Herein, we examine the known artificial habitat associations of amphibian species globally, demonstrating artificial habitat use is dependent on their conservation status, life history, taxonomic order, and geographical location. Approximately one-third of all amphibians were found to use artificial habitats, including nearly half of all non-threatened and one-sixth of threatened species, with usage decreasing as conservation status increased. Terrestrial, generalist, and caecilian species were much more likely to use artificial habitats. Non-threatened species were more likely to utilize artificial habitats such as aquaculture ponds, pastureland, canals, excavations, urban areas, and rural gardens. Plantations, heavily degraded former forests, and wastewater treatment areas contained a greater proportion of threatened species, particularly in Afrotropical, Indomalayan, and Oceanian regions. Countries with the most amphibians utilizing artificial habitats were Brazil, Colombia, Peru, Madagascar, and Ecuador. However, the greatest number of threatened species using artificial habitats were found in Mexico, Madagascar, India, Sri Lanka, and China. We highlight the potential value or threat of each artificial habitat type, which may be used to better focus valuable conservation efforts.
