Adaptive introgression as a driver of local adaptation to climate in European white oaks. [PDF]

New Phytol, 2020
AbstractLatitudinal and elevational gradients provide valuable experimental settings for studies of the potential impact of global warming on forest tree species. The availability of long-term phenological surveys in common garden experiments for traits associated with climate, such as bud flushing, for sessile oaks (Quercus petraea), provides an ideal

Introgression threatens the survival of the critically endangered freshwater crayfish Cherax tenuimanus (Decapoda: Parastacidae) in the wild. [PDF]

PLoS ONE, 2015
Hybridization and genetic introgression following the introduction of exotic species can pose a significant threat to the survival of geographically restricted species.

Genomic consequences of human‐mediated translocations in margin populations of an endangered amphibian

Evolutionary Applications, 2021
Due to their isolated and often fragmented nature, range margin populations are especially vulnerable to rapid environmental change. To maintain genetic diversity and adaptive potential, gene flow from disjunct populations might therefore be crucial to ...

Adaptive introgression underlies polymorphic seasonal camouflage in snowshoe hares [PDF]

Science, 2018
Hybrid camouflage variation Snowshoe hares molt from a brown coat to a white coat in winter. In some populations, however, where winter snow is less extensive, hares molt from a brown coat to a brown coat. Jones et al.

Historical Selection, Adaptation Signatures, and Ambiguity of Introgressions in Wheat

International Journal of Molecular Sciences, 2023
Wheat was one of the crops domesticated in the Fertile Crescent region approximately 10,000 years ago. Despite undergoing recent polyploidization, hull-to-free-thresh transition events, and domestication bottlenecks, wheat is now grown in over 130 countries and accounts for a quarter of the world’s cereal production.

Genetic evidence for hybrid trait speciation in heliconius butterflies. [PDF]

PLoS Genetics, 2010
Homoploid hybrid speciation is the formation of a new hybrid species without change in chromosome number. So far, there has been a lack of direct molecular evidence for hybridization generating novel traits directly involved in animal speciation ...

Hybrids and horizontal transfer: introgression allows adaptive allele discovery [PDF]

Journal of Experimental Botany, 2017
Evolution has devised countless remarkable solutions to diverse challenges. Understanding the mechanistic basis of these solutions provides insights into how biological systems can be subtly tweaked without maladaptive consequences. The knowledge gained from illuminating these mechanisms is equally important to our understanding of fundamental ...

Introgression among North American wild grapes (Vitis) fuels biotic and abiotic adaptation

Genome Biology, 2021
Background Introgressive hybridization can reassort genetic variants into beneficial combinations, permitting adaptation to new ecological niches. To evaluate evolutionary patterns and dynamics that contribute to introgression, we investigate six wild ...

Phylogenomic analyses highlight innovation and introgression in the continental radiations of Fagaceae across the Northern Hemisphere

Nature Communications, 2022
Fagaceae are diverse family including trees of ecological and economic importance. This phylogenomic analysis of nuclear and plastid genomes reconstructs evolutionary history and finds evidence of multiple adaptive introgression events in this important ...
