Hybridization and introgression in sympatric and allopatric populations of four oak species

open access: yesBMC Plant Biology, 2021
Background Hybridization and introgression are vital sources of novel genetic variation driving diversification during reticulated evolution. Quercus is an important model clade, having extraordinary diverse and abundant members in the Northern ...

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Adaptive introgression during environmental change can weaken reproductive isolation [PDF]

open access: yesNature Climate Change, 2019
AbstractAnthropogenic climate change is an urgent threat to species diversity. One aspect of this threat is the collapse of species reproductive barriers through increased hybridization. The primary mechanism for this collapse is thought to be the weakening of ecologically-mediated reproductive barriers, as demonstrated in many cases of “reverse ...

Introgression drives adaptation to the plateau environment in a subterranean rodent

open access: yesBMC Biology
Background Introgression has repeatedly been shown to play an important role in the adaptation of species to extreme environments, yet how introgression enables rodents with specialized subterranean lifestyle to acclimatize to high altitudes is still ...

Ancient introgression shapes the evolutionary history of a California Channel Island relictual species, island oak (Quercus tomentella)

open access: yesGlobal Ecology and Conservation
Hybridization, a common phenomenon among plants, can result in the exchange of neutral or beneficial genetic loci, potentially leading to adaptive introgression. It is often difficult to know whether the genetic composition of contemporary species is the

Selective sorting of ancestral introgression in maize and teosinte along an elevational cline.

open access: yesPLoS Genetics, 2021
While often deleterious, hybridization can also be a key source of genetic variation and pre-adapted haplotypes, enabling rapid evolution and niche expansion.

Transcriptomic stress responses in Vaccinium spp. F1 hybrids: Implications for temperature‐resilient cranberry breeding using a crop wild relative

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate extremes threaten the sustainability of cranberry production, a culturally and economically important North American crop. This study demonstrates that wild cranberries (Vaccinium oxycoccos) harbor genetic variation that may enhance cold stress resilience when introduced into cultivated cranberry through hybridization.

Breeding for multi‐stress resilience in crops: Myth or possibility?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

Hybrid introgression as a mechanism of rapid evolution and resilience to climate change in a riparian tree species

open access: yesCommunications Biology
Determining whether organisms can undergo adaptive evolution at a pace commensurate with contemporary climate change is critical to understanding and predicting the consequences of such change.

Human‐modified canids in human‐modified landscapes: The evolutionary consequences of hybridization for grey wolves and free‐ranging domestic dogs

open access: yesEvolutionary Applications, 2021
Introgressive hybridization between domestic animals and their wild relatives is an indirect form of human‐induced evolution, altering gene pools and phenotypic traits of wild and domestic populations.
