Reduced Offspring Viability Is Associated With Long-Term Stability of a Narrow Avian Hybrid Zone. [PDF]

Ecol Evol
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus). [PDF]

Mol Ecol
ABSTRACT Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations.

Climate and hybridization shape stomatal trait evolution in Populus. [PDF]

New Phytol
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored. [PDF]

New Phytol
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Simulating the efficacy of wolf-dog hybridization management with individual-based modeling. [PDF]

Conserv Biol
In the photo, an introgressed adult wolf–dog in the Northern Apennines, Italy, not far from the city of Bologna. Part of a research program, this male has been sterilized and released back in its own pack with a Global Positioning Collar. Abstract Introgressive hybridization between wolves and dogs is a conservation concern due to its potentially ...

Safeguarding the genetic integrity of native pollinators requires stronger regulations on commercial lines

Ecological Solutions and Evidence, Volume 1, Issue 1, July 2020., 2020
Wild and commercial bumblebees from different subspecies are hybridizing. This genetic introgression is widespread and threatens local adaptations. Stronger regulations are needed to safeguard pollinators' genetic diversity. Abstract Every year more than 1 million commercial bumblebee colonies are deployed in greenhouses worldwide for their pollination

DEVELOPMENT OF NON-TIDAL ADAPTIVE RICE VARIETIES: MOLECULAR MARKER ASSISTED SELECTION OF BC2F1 PROGENIES

Biovalentia: Biological Research Journal, 2022
Submergence stress and drought stress are main abiotic constraints encountered in South Sumatra swampland rice cultivation area. The development of new abiotic stress tolerant varieties through the introgresion of tolerance genes, such as the Sub1 gene (

Floating, Boating and Introgression: Molecular Techniques and the Ancestry of Coconut Palm Populations on Pacific Islands [PDF]

, 2004
It has previously been suggested that the coconut populations of Pacific islands arose by introgression between wild types that disseminated by floating from an ancestral center of origin and domestic types that were brought in small boats from a center ...
