INTRODUCTION M D ODERN population systematics rests on the assumption that species arise when a parent population is divided into geographical fractions, each isolated from the next by physiographic (or biotic) barriers. During such geographic isolation, the daughter populations can accumulate genetic differences, some or all of which reduce their chances of interbreeding freely and effectively. As soon as these differences accumulate to the point where they constitute a reproductive barrier… 

Rapid parapatric speciation on holey adaptive landscapes

It is demonstrated that rapid speciation on the time–scale of hundreds of generations is plausible without the need for extreme founder events, complete geographic isolation, the existence of distinct adaptive peaks or selection for local adaptation, and the plausibility of speciation is enhanced by population subdivision.

EVOLUTION IN PERIPHERAL ISOLATED POPULATIONS: CARPODACUS FINCHES ON THE CALIFORNIA ISLANDS

Analysis of phenetic similarity among populations of the house finch from the California Islands and the western U.S. focuses on barriers to dispersal and the accumulation of morphological differences among populations.

The Edge Effect in Population Genetics

It is suggested here that in two examples from the European fauna (bank voles of the genus Clethrionomys and the snail Cepaea nemoralis) the distinct edge populations are less likely to be relicts than recent developments.

Geographic variation in genetic and demographic performance: new insights from an old biogeographical paradigm

A framework is proposed that integrates species' ecological niche characteristics together with current and past range structure to investigate spatial patterns of genetic and demographic variation across species ranges and disentangle the relative contribution of geographical, ecological and historical processes on the spatial distribution of Genetic and demographic parameters.

EVOLUTIONARY RELATIONSHIPS IN MACROTUS (MAMMALIA: CHIROPTERA) : BIOCHEMICAL VARIATION AND KARYOLOGY

Karyotypic and electrophoretic data suggest that specimens from the Antillean population (Macrotus waterhousii) are conspecific with populations of the southern mainland taxa and the data do not support the centrifugal model of speciation in this genus.

DYNAMICS OF SPECIATION AND DIVERSIFICATION IN A METAPOPULATION

This framework can be used to approach a number of questions such as species‐area distribution, species‐range size distribution, the rate of ecological turnover, asymmetries of range division between sister species, waiting time until speciation and extinction, the relationship between the geographic range size and the probability of speciation, and the relationships between subpopulation‐level parameters and metapopulation‐ level parameters.

The geography and ecology of plant speciation: range overlap and niche divergence in sister species

It is found that plants exhibit strikingly different age-range correlation patterns from those found for animals; the latter broadly support allopatric speciation as the primary mode of speciation.

A biogeographical perspective on ecological systems: some personal reflections

A model of distribution and abundance within a regional community is consistent with much of what the authors know about the interactions between pathogens and their host populations, but testing the model will require the development of a new research programme focused on endemic pathogen effects in natural communities.

BIOLOGY OF ECOLOGICALLY MARGINAL POPULATIONS OF ANTHOXANTHUM ODORATUM. I. PHENETICS AND DYNAMICS

Justification for the evolutionary study of marginal populations can be provided from at least five points of view: (1) peripheral populations are postulated to play a central role in speciation phenomena but in very different ways; (2) they are attributed a major role in 'bursts' of adaptive radiation; and (3) comparison with central populations yields information on selection processes.

CHROMOSOMAL EVOLUTION AND THE MODE OF SPECIATION IN THREE SPECIES OF PEROMYSCUS

This study was designed to yield additional data on the cytogenetics of three species of the Peromyscus maniculatus complex of deer mice in order to evaluate the "centrifugal speciation" model as a viable explanation of the evolutionary origin of the complex.

An outline of the dynamics of animal populations.

The characteristic of balance is sustained and effective compensatory reaction which maintains populations in being in spite of even violent changes in the environment, and which adjusts their densities in general conformity with prevailing conditions.

Modes of Selection

It is concluded with Blum (1951) that evolution took the form at first of decreasing mutability and along with this may have occurred the evolution of stable genic association in cells, and mechanisms of exact duplication of the entire system by mitosis.

Studies on the Origin of Cultivated Plants

The great increase in genetical research and the marked desire of many geneticists to link their studies with other aspects of biology is leading to renewed interest in the taxonomic and geographical history of the authors' common cultivated plants.
