# Stochastic communities: a mathematical theory of biodiversity

##### By: Dewdney, A. K.

Material type: BookPublisher: Boca Raton CRC Press 2017Description: xiv, 193p. With index.ISBN: 9781138197022.Subject(s): Population biology - Mathematical models | Species diversity - Mathematical models | Stochastic models | EcologyDDC classification: 577 Summary: Stochastic Communities presents a theory of biodiversity by analyzing the distribution of abundances among species in the context of a community. The basis of this theory is a distribution called the "J distribution." This distribution is a pure hyperbola and mathematically implied by the "stochastic species hypothesis" assigning equal probabilities of birth and death within the population of each species over varying periods of time. The J distribution in natural communities has strong empirical support resulting from a meta-study and strong theoretical support from a theorem that is mathematically implied by the stochastic species hypothesis. https://www.crcpress.com/Stochastic-Communities-A-Mathematical-Theory-of-Biodiversity/Dewdney/p/book/9781138197022Item type | Current location | Collection | Call number | Status | Date due | Barcode |
