Bringing the Hutchinsonian niche into the 21st century: ecological and evolutionary perspectives
RD Holt - Proceedings of the National Academy of …, 2009 - National Acad Sciences
G. Evelyn Hutchinson more than a half century ago proposed that one could characterize the
ecological niche of a species as an abstract mapping of population dynamics onto an
environmental space, the axes of which are abiotic and biotic factors that influence birth and
death rates. If a habitat has conditions within a species9 niche, a population should persist
without immigration from external sources, whereas if conditions are outside the niche, it
faces extinction. Analyses of species9 niches are essential to understanding controls on …
