Microspatial Genetic Differentiation in Natural Populations of ,gists as the predominant means of speciation among sexually reproducing species. This emphasis on how species are adapted to general climatic and geographical variation has often diverted attention from the problems of adaptation to local environmental heterogeneity.

Determinants of Government Receiptsledge of even a few of the environmental cues that initiate a behavioral response can be fundamental for an eventual understanding of gene-environment interaction. However, ecological genetics is derived from fields as profound as phylogenetic histories on the one hand and biogeographic origins on the other.

An Axiomatic Basis for Quantum Mechanics developed at very different levels of organization. Evolution may be quite appropriately viewed either in terms of changes in the phenotypic population, or of changes in frequencies of genetic units. Quite obviously, however, different questions assume importance from those different aspects. One w

In evolutionary theory, natural selection is viewed as producing traits which maximize the fitness of the individuals carrying them relative to the fitness of individuals with alternative traits. The criterion of fitness maximization is

An Economic Analysis of Conflicts Indeed, the generalizations resulting from investigations of intraspecific variation have been canonized as “ecogeographical rules” (Mayr, 1963). The study of geographic variation led to the formulation of the allopatric or geographic model of speciation which is accepted by most evolutionary biolo

https://doi.org/10.1007/978-981-10-5771-7 speciation (Mayr, 1963a; Dobzhansky, 1970) suggests that new species arise in geographically isolated populations through the gradual accumulation of genetic differences. Mayr (1963a) contends that geographic speciation is “the almost exclusive mode of speciation among animals” (p. 481). However, d
