Hybridization as a conservation management tool (2019, background): “Enhancing adaptive potential of a population via hybridization is currently an underutilized management choice due to its perceived risks (Fitzpatrick et al., 2016; Frankham et al., 2011; Hufford & Mazer 2003) and limitations in its existing legal framework (Wayne & Shaffer 2016).”
Genetic factors in threatened species recovery plans on three continents (2016, background): “Outbre eding depression, while apparently less concerning than inbreeding depression because its occurrence is often predictable and its effects are usually mild and/or transient (Frankham et al. 2011), has been raised in some discussions on management policies regarding seed sourcing for restoratio”
GENETIC ISOLATION BY ENVIRONMENT OR DISTANCE: WHICH PATTERN OF GENE FLOW IS MOST COMMON? (2014, background): “Experimental gene flow studies testing various spatial and environmental separation are needed to develop a predictive, contextual framework for the effects of gene flow (Frankham et al. 2011), including the effects of gradient steepness (Bridle et al. 2010).”
A framework for incorporating evolutionary genomics into biodiversity conservation and management (2015, background): “But uniqueness in endangered populations and species is more likely to be a result of drift processes than mutation alone [239] and the risk of outbreeding depression has clearly been overstated [240].”
Genetic rescue of small inbred populations: meta-analysis reveals large and consistent benefits of gene flow. (2015, methodology): “Despite this, only ~ 10–20 genetic rescues have been attempted for conservation purposes (Adams et al. 2011; Frankham et al. 2011), probably a miniscule proportion of the populations that might benefit from outcrossing (Frankham et al.”
Distance, dams and drift: what structures populations of an endangered, benthic stream fish? (2013, background): “partly depend on the factors that produced isolation, and whether they arose from natural or anthropogenic sources (Frankham et al., 2011).”
Bridging the gap: a genetic assessment framework for population‐level threatened plant conservation prioritization and decision‐making (2016, background): “…2014), but in the absence of such studies, it may be appropriate to proceed with caution and take a risk management approach (Byrne et al., 2011; Frankham et al., 2011; Weeks et al., 2011), for example, by establishing new mixed-source populations in isolation from indigenous populations,…”
Implications of different species concepts for conserving biodiversity (2012, background): “However, fixed chromosomal differences and/or adaptation to different environments are good predictors of outbreeding depression if populations are crossed (see Frankham et al., 2011; Sexton et al., 2011).”
Restoring species through reintroductions: strategies for source population selection (2015, background): “…to outbreeding depression or hybrid breakdown (Lesica & Allendorf 1999; Weeks et al. 2011; IUCN 2013; Cochran-Biederman et al. 2015), especially with increasing genetic or environmental distance between the source populations (Montalvo & Ellstrand 2001; Frankham et al. 2011; Hufford et al. 2012).”
Assisted Gene Flow to Facilitate Local Adaptation to Climate Change (2013, background): “Epistatic Incompatibilities Outbreeding depression may result from chromosomal differences between populations that cause partial or complete sterility (Frankham et al. 2011).”
Genetics in conservation management: Revised recommendations for the 50/500 rules, Red List criteria and population viability analyses (2014, background): “For previously connected populations that now have limited gene flow and evidence of genetic erosion, we recommend augmentation of gene flow be considered, provided the risk of outbreeding depression is low (Frankham et al., 2011).”
Hybridization and extinction (2016, background): “Any outbreeding depression must be outweighed by the fitness benefits of hybridization, for example, by compensating for deleterious mutations that have accumulated in an inbred population (Frankham et al. 2011; Whiteley et al. 2015) or locally adaptive immigrant alleles (Aitken and Whitlock 2013).”
The Wayward Dog: Is the Australian native dog or Dingo a distinct species? (2017, background): “The degree of genetic incompatibility between populations tends to be related to the amount of genetic divergence that has occurred as a consequence of genetic drift or selection (e.g. Nosil et al. 2003; Frankham et al. 2011, 2012).”
Assessing the benefits and risks of translocations in changing environments: a genetic perspective (2011, background): “The risk of outbreeding depression, however, should be carefully weighed against the substantial risk that ongoing loss of genetic diversity and inbreeding poses to the long-term persistence of populations (Edmands 2007; Lopez et al. 2009; Frankham et al. 2011), a point we discuss further below.”
