Recent interest in the role of ecology in species formation has led to renewed discussion of
the stages in the process of speciation. Although attempts to classify the stages in the …

Species inhabit complex environments and respond to selection imposed by numerous
abiotic and biotic conditions that vary in both space and time. Environmental heterogeneity …

Divergent natural selection promotes local adaptation and can lead to reproductive isolation
of populations in contrasting environments; however, the genetic basis of local adaptation …

Elucidating the factors influencing genetic differentiation is an important task in biology, and
the relative contribution from natural selection and genetic drift has long been debated. In …

The relative contribution of advantageous and neutral mutations to the evolutionary process
is a central problem in evolutionary biology. Current estimates suggest that whereas …

Understanding the population structure and linkage disequilibrium in an association panel
can effectively avoid spurious associations and improve the accuracy in association …

Information on genetic diversity and population structure of elite wheat (Triticum aestivum L.)
breeding lines promotes effective use of genetic resources. We analyzed 205 elite wheat …

The selection and development of a study system for evolutionary and ecological functional
genomics (EEFG) depend on a variety of factors. Here, we present the genus Boechera as …

Abiotic and biotic conditions often vary continuously across the landscape, imposing
divergent selection on local populations. We used a provenance trial approach to examine …

Fitness trade-offs across episodes of selection and environments influence life-history
evolution and adaptive population divergence. Documenting these trade-offs remains …
