Persistence or extinction: Through a mathematical lens
Philadelphia, PA (SPX) Nov 16, 2012
Scientists have estimated that there are 1.7 million species of animals, plants and algae on earth, and new species continue to be discovered. Unfortunately, as new species are found, many are also disappearing, contributing to a net decrease in biodiversity. The more diversity there is in a population, the longer the ecosystem can sustain itself. Hence, biodiversity is key to ecosystem resilience. Disease, destruction of habitats, pollution, chemical and pesticide use, increased UV-B radiation, a ... read more
