(Phys.org)—A team of researchers with the University of the Witwatersrand in South Africa has found evidence that suggests the aardvark may face a large decrease in population as the planet heats up due to global warming. In their paper published in the journal Biology Letters, the group describes how they fastened monitors to a group of aardvarks who by happenstance were forced to endure a severe drought—and how the animals fared.
