Genetic load: genomic estimates and applications in non-model animals

G Bertorelle, F Raffini, M Bosse, C Bortoluzzi… - Nature Reviews …, 2022 - nature.com

Prevalence and adaptive impact of introgression

NB Edelman, J Mallet - Annual Review of Genetics, 2021 - annualreviews.org
Alleles that introgress between species can influence the evolutionary and ecological fate of

Deleterious variation in natural populations and implications for conservation genetics

J Robinson, CC Kyriazis, SC Yuan… - Annual review of …, 2023 - annualreviews.org

The critically endangered vaquita is not doomed to extinction by inbreeding depression

JA Robinson, CC Kyriazis, SF Nigenda-Morales… - Science, 2022 - science.org
In cases of severe wildlife population decline, a key question is whether recovery efforts will
be impeded by genetic factors, such as inbreeding depression. Decades of excess mortality …

Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation

K Ralls, P Sunnucks, RC Lacy, R Frankham - Biological Conservation, 2020 - Elsevier
Genetic rescue–ameliorating inbreeding depression and restoring genetic diversity of inbred
populations through gene flow-is valuable in wildlife conservation. Empirically validated …

Genomic evidence for inbreeding depression and purging of deleterious genetic variation in Indian tigers

A Khan, K Patel, H Shukla… - Proceedings of the …, 2021 - National Acad Sciences
Increasing habitat fragmentation leads to wild populations becoming small, isolated, and
threatened by inbreeding depression. However, small populations may be able to purge …
