Researchers have been studying the nature of life on Earth and the role of biodiversity. Given the current state of slow biodiversity loss as a variety of species populations are gradually diminishing toward the poles, scientists from the University of Chicago, University of California, Berkeley, and University of California, San Diego try to reconcile two competing ideas that explain this phenomenon in their study published in The American Naturalist.
