Patterns of variation and evolution at a given site in a genome can be strongly influenced by
the effects of selection at genetically linked sites. In particular, the recombination rates of …

The field of population genomics has grown rapidly in response to the recent advent of
affordable, large-scale sequencing technologies. As opposed to the situation during the …

Background Microbial inhabitants of soils are important to ecosystem and planetary
functions, yet there are large gaps in our knowledge of their diversity and ecology. The …

The relative evolutionary roles of adaptive and non-adaptive processes remain a central
question in population genetics. Resolution of this debate has been difficult as an …

The domestic dog represents one of the most dramatic long-term evolutionary experiments
undertaken by humans. From a large wolf-like progenitor, unparalleled diversity in …

Positive selection occurs when an allele is favored by natural selection. The frequency of the
favored allele increases in the population and due to genetic hitchhiking the neighboring …

A composite likelihood ratio test implemented in the program sweepfinder is a commonly
used method for scanning a genome for recent selective sweeps. sweepfinder uses …

Since the initial description of the genomic patterns expected under models of positive
selection acting on standing genetic variation and on multiple beneficial mutations—so …

Underlying any understanding of the mode, tempo and relative importance of the adaptive
process in the evolution of natural populations is the notion of whether adaptation is …

The interplay of gene flow, genetic drift, and local selective pressure is a dynamic process
that has been well studied from a theoretical perspective over the last century. Wright and …
