Protecting the biodiversity of the Amazon basin is an immense undertaking, and to its credit the Brazilian government has a set procedure for doing so. However, there are gaps in the process that may prevent the authorities from fully protecting the species that call this place home. To investigate this, a recent study in mongabay.com’s open-access journal Tropical Conservation Science uses as an example the brilliant-thighed frog (Allobates femoralis), a species that is found across the Amazon Basin—including the area surrounding the soon-to-be dammed Xingu River.
