Competition and Regional Coexistence
Abstract
A model of the competition between two species is developed which is based on the work of Cohen (1970) and Levins and Culver (1971) and which considers the effect of competition on the colonization and extinction rates of the two species. The results are that in some cases it is possible for one species to exclude another species from a geographic region, but there is no possibility of a "priority effect" where the first species in the region can always exclude the other. Thus the equilibrium level of each species is determined by the parameters of the system and not by the initial conditions. Also, it is possible for two similar species to coexist in a region. A predator can increase the extinction rate of each species and, in some cases, permit coexistence where it would otherwise not be possible.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
