Genetic diversity of walking catfish, Clarias macrocephalus, in Thailand and evidence of genetic introgression from introduced farmed C. gariepinus (2004, background): “While contribution of natural interspecific hybridization to evolution of plant and animal taxa had been realized, anthropogenic genetic introgression between species is causing extinction of many taxa by both replacement and genetic mixing (Huxel, 1999; Allendorf et al., 2001).”
Introgression variability among Iberian brown trout Evolutionary Significant Units: the influence of local management and environmental features (2006, background): “Rare alleles contribute little to overall genetic variation, but they may offer unique responses to future evolutionary challenges ( Allendorf et al., 2001; Utter, 2001).”
Hybridization and phylogeography of the Mozambique tilapia Oreochromis mossambicus in southern Africa evidenced by mitochondrial and microsatellite DNA genotyping (2006, background): “Following Allendorf et al. (2001), this hybrid population is of no conservation value.”
The Role of Hybridization in the Evolution of Reef Corals (2006, background): “…they fall outside the framework of conventional species definitions or are interpreted as jeopardizing the persistence of pure native species (e.g., Allendorf et al. 2001) ignore the dynamic nature of species and the potentially integral role that hybridization may play in the founding of lineages.”
The major threats to Atlantic salmon in Norway (2017, positive): “The major impact on Norwegian Atlantic salmon populations is introgression (Allendorf et al., 2001) from escaped farmed Atlantic salmon (Glover et al., 2012, 2013; Karlsson et al., 2016).”
A molecular approach to detect hybridisation between crucian carp (Carassius carassius) and non-indigenous carp species (Carassius spp. and Cyprinus carpio) (2005, background): “Removal of goldfish and hybrids from these populations is likely to be beneficial and habitat improvement could further help decrease rates of hybridisation ( Allendorf et al., 2001 ).”
Local Habitat, Watershed, and Biotic Factors Influencing the Spread of Hybridization between Native Westslope Cutthroat Trout and Introduced Rainbow Trout (2009, background): “clarkii lewisi, threatening this highly divergent subspecies with genomic extinction (Allendorf and Leary 1988; Allendorf et al. 2001).”
Amphibian declines: future directions (2003, methodology): “Genetic markers can help to detect recent hybridization events or interspecific gene flow (reviewed in Allendorf et al., 2001).”
Hybridization between a native and introduced predator of Adelgidae: an unintended result of classical biological control. (2012, background): “A particular hybridization event can range from very little genetic introgression when matings are rare or hybrids have low fitness, to complete admixture when the homogenizing effects of gene flow overwhelm any existing isolating mechanisms (Allendorf et al., 2001).”
Methods for Assessing Fish Populations (2010, background): “Such information is important because it may inform managers of whether hybrid progeny have low survival rates or are infertile, such as hybrids between bull trout and brook trout (Allendorf et al. 2001).”
Host races in plant-feeding insects and their importance in sympatric speciation. (2002, background): “…differences should be considered on an equal par with ‘genetic exchangeability’ (i.e. gene ow) in conservation, and a number of other conservationists have argued that hybridizing or hybridized taxa can be important components of biodiversity worth conserving (e.g. Allendorf et al. 2001).”
Climate change induced hybridization in flying squirrels (2010, background): “The conservation implications of hybridization are not straightforward (Allendorf et al., 2001).”
Status and Conservation of Westslope Cutthroat Trout within the Western United States (2005, background): “2003), and (2) several authors have suggested that conserving slightly introgressed populations was a reasonable strategy to ensure the conservation of local phenotypic, genotypic, and behavioral variation but should be based on local considerations (Dowling and Childs 1992; Allendorf et al. 2001; P”
Genetics and conservation of wolves Canis lupus in Europe (2011, background): “However, their diffusion is poorly known, the biological consequences of introgression are controversial (Anderson et al. 2009) and official guidelines to manage hybrids do not exist (Allendorf et al. 2001).”
Molecular analysis of hybridisation between wild and domestic cats (Felis silvestris) in Portugal: implications for conservation (2008, background): “…of morphological criteria allowing unambiguous distinction between the three forms, along with the particularly challenging identification of hybrids beyond first generation (Daniels et al. 1998; Allendorf et al. 2001), prompted the initiation of genetic studies into diagnostic molecular traits.”
Ecological Impacts of Nonnative Freshwater Fishes (2011, background): “Hybridization and Introgression Hybridization between native and non-native species has been reported in many fish families, leading to growing concerns of extinction risk (Rhymer and Simberloff 1996; Allendorf et al. 2001).”
