Cosmos (Jan. 5) -- New research at Illinois holds the possibility of solving a known problem in ecology called the “biodiversity paradox,” in which if two species occupy the same ecological niche, one should win out over the other, and result in a decrease in biodiversity. But that theory is disproven by the actual biodiversity observed in nature. Chi Xue and Nigel Goldenfeld of the Carl R. Woese Institute for Genomic Biology at Illinois have developed a mathematical model that more realistically extends and refines the “Kill the Winner” model. Also: Inverse (Jan. 5)
