Dynamics of Adaptive Introgression from Archaic to Modern Humans.

PaleoAnthropology, 2006
Recent evidence from the genomic variation of living people documents genetic contributions from archaic to later modern humans. This evidence of introgression contrasts with earlier findings from single loci that appeared to exclude archaic human ...

Mating behaviour influences the direction and geographic extent of introgression in New Zealand fishing spiders (Dolomedes) [PDF]

Introgression is a highly influential process in evolution, where genes flow between species that are not fully reproductively isolated. Studies on introgression often focus on describing gene transfer and environmental changes that facilitate the ...

Mimetic Butterflies Introgress to Impress

PLoS Genetics, 2012
The extent to which hybridization and the resulting interspecific gene flow (introgression) contribute to adaptation is a matter of great debate. On the one hand, fertile hybrids have the potential to transfer beneficial alleles between species [1] or even to spawn new species [2].

Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

Journal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

A Highly Divergent Mitochondrial Genome in Extant Cape Buffalo From Addo Elephant National Park, South Africa

Ecology and Evolution
The reduced cost of next‐generation sequencing (NGS) has allowed researchers to generate nuclear and mitochondrial genome data to gain deeper insights into the phylogeography, evolutionary history and biology of non‐model species. While the Cape buffalo (

Towards Introgression Between Watermelon (Citrullus lanatus) and Its Wild Relative, Bitter Apple (C. colocynthis)

Horticulturae
The genetic diversity of cultivated crops is limited, largely as a result of domestication bottlenecks and the selective pressures imposed during modern breeding.

Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Hybridization breaks species barriers in long-term coevolution of a cyanobacterial population

eLife
Bacterial species often undergo rampant recombination yet maintain cohesive genomic identity. Ecological differences can generate recombination barriers between species and sustain genomic clusters in the short term.

Climate‐driven niche filtering limits post‐dispersal establishment and genomic introgression in a riverine shrub

Journal of Integrative Plant Biology, EarlyView.
Integrated biogeographic analysis and macroecological insights reveal that habitat differences drive genetic differentiation Debregeasia orientalis C. J. Chen, a dominant riparian shrub distributed across multiple biodiversity hotspots, and different lineages vary greatly in adaptability to future climate.
