Distributional shifts driven by Quaternary climatic oscillations have been suggested to cause interspecific hybridization and introgression. In this study, we aimed to test this hypothesis by using population transcriptomes and coalescent modeling of two

Dispersal and gene flow in free-living marine nematodes [PDF]
Dispersal and gene flow determine connectivity among populations, and can be studied through population genetics and phylogeography. We here review the results of such a framework for free-living marine nematodes.

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Targeted gene flow for conservation [PDF]
AbstractAnthropogenic threats often impose strong selection on affected populations, causing rapid evolutionary responses. Unfortunately, these adaptive responses are rarely harnessed for conservation. We suggest that conservation managers pay close attention to adaptive processes and geographic variation, with an eye to using them for conservation ...

Evidence of gene flow between transgenic and non-transgenic maize in Colombia
Maize (Zea mays) is an important crop worldwide and is essential for industry. Many transgenic cultivars of maize have been developed over the years from this species, producing cultivars resistant to herbicides and insects, among other things.

The analysis of gene flow patterns can provide important insights into population dynamics in the context of landscape ecology. In lizards, this approach has been used to evaluate patterns related to climate change, habitat fragmentation, and taxonomic ...

Local adaptation with high gene flow: temperature parameters drive adaptation to altitude in the common frog (Rana temporaria) [PDF]
Both environmental and genetic influences can result in phenotypic variation. Quantifying the relative contributions of local adaptation and phenotypic plasticity to phenotypes is key to understanding the effect of environmental variation on populations.

A Continuous Method for Gene Flow [PDF]
Abstract Most modern population genetics inference methods are based on the coalescence framework. Methods that allow estimating parameters of structured populations commonly insert migration events into the genealogies. For these methods the calculation of the coalescence probability density of a genealogy requires a product over all ...

Diffuse flow environments within basalt- and sediment-based hydrothermal vent ecosystems harbor specialized microbial communities [PDF]
Hydrothermal vents differ both in surface input and subsurface geochemistry. The effects of these differences on their microbial communities are not clear.

Pattern of population structuring between Belgian and Estonian bumblebees [PDF]
Several population genetic studies investigated the extent of gene flow and population connectivity in bumblebees. In general, no restriction in gene flow is considered for mainland populations of common bumblebee species.
