Introduction : extent, processes and evolutionary impact of interspecific hybridization in animals [PDF]

, 2008
Since the time of Charles Darwin, studies of interspecific hybridization have been a major focus for evolutionary biologists. Although this phenomenon has often been viewed as problematic in the fields of ecology, taxonomy and systematics, it has become ...

Population genomic monitoring provides insight into conservation status but no correlation with demographic estimates of extinction risk in a threatened trout

Evolutionary Applications, 2022
The current extinction crisis requires effective assessment and monitoring tools. Genetic approaches are appealing given the relative ease of field sampling required to estimate genetic diversity characteristics assumed related to population size ...

Using molecular tools to guide management of invasive alien species: assessing the genetic impact of a recently introduced island bird population [PDF]

, 2015
Aim: Biological invasions are a major threat to island biodiversity and are responsible for a large proportion of species declines and extinctions worldwide.

Species integrity, introgression, and genetic variation across a coral reef fish hybrid zone

Ecology and Evolution, 2020
Hybridization and introgression are evolutionarily significant phenomena breaking down species boundaries. “Hybrid zones” (regions of species overlap and hybridization) enable quantification of hybridization frequency and examination of mechanisms ...

Tracing the footprints of a moving hybrid zone under a demographic history of speciation with gene flow

Evolutionary Applications, 2020
A lack of optimal gene combinations, as well as low levels of genetic diversity, is often associated with the formation of species range margins. Conservation efforts rely on predictive modelling using abiotic variables and assessments of genetic ...

Additive and non-additive epigenetic signatures of natural hybridization between fish species with different mating systems

Epigenetics, 2022
Hybridization is a major source of evolutionary innovation. In plants, epigenetic mechanisms can help to stabilize hybrid genomes and contribute to reproductive isolation, but the relationship between genetic and epigenetic changes in animal hybrids is ...

Genetic evaluation of F2 and F3 interspecific hybrids of mung bean (Vigna radiata L. Wilczek) using retrotransposon‐based insertion polymorphism and sequence‐related amplified polymorphism markers

Indonesian Journal of Biotechnology, 2023
Mung bean (Vigna radiata L. Wilczek) is a self‐pollinating and indispensable pulse crop in Indonesia. While low yield productivity is a major concern, genetic improvement is possible through interspecific hybridization.

Comparative BAC-based mapping in the white-throated sparrow, a novel behavioral genomics model, using interspecies overgo hybridization [PDF]

, 2011
BACKGROUND The genomics era has produced an arsenal of resources from sequenced organisms allowing researchers to target species that do not have comparable mapping and sequence information.

An Immuno-Genetic Hybrid Algorithm

International Journal of Computers Communications & Control, 2009
The construction of artificial systems by drawing inspiration from natural systems is not a new idea. The Artificial Neural Network (ANN) and Genetic Algorithms (GAs) are good examples of successful applications of the biological metaphor to the solution of computational problems.
