Population size and taxonomic diversity in geologic time: a brief look at two density-dependent models

摘要: Density-dependent models of changes in the population size a fossil species geologic time, or taxonomic diversity group can be formulated using (1) logistic equation model (2) piecewise linear/stochastic ofGrenfell et al. One may test (or at least get an indication) whether not one two types holds for particular estimate diversity) Xt by plotting value as function time plus scattergram Xt+1 versus all pairs estimates {Xt, Xt+1} successive time.
