Understanding tropical rainforest biodiversity with treefrogs and ecological history

Lush climates alone do not account for the vast biodiversity in tropical rainforests. Research on treefrogs from around the world, covering 123 sites and gathering DNA sequence data for 360 species of treefrogs, has provided a new understanding of biodiversity in tropical rainforests: some groups of treefrogs have existed together in the Amazon Basin for more than 60 million years. A more recent publication supports this finding, noting that forests in Canada and Europe may have much more in common with tropical rainforests than previously believed, but tropical forests have not been subjected to glaciations and mass extinctions, allowing for much greater biodiversity.
