Does harvest affect genetic diversity in grey wolves?

Abstract: Harvest can affect vital rates such as reproduction and survival, but also genetic measures of individual and population health. Grey wolves (Canis lupus) live and breed in groups, and effective population size is a small fraction of total abundance. As a result, genetic diversity of wolves may be particularly sensitive to harvest. We evaluated how harvest affected genetic diversity and relatedness in wolves. We hypothesized that harvest would (a) reduce relatedness of individuals within groups in a subpopulat… Show more

“…Thus, inbreeding avoidance appears to be at least one mechanism maintaining genetic diversity in this population. Observed heterozygosity (0.75; range 0.50–1.00) was similar to that reported by Ausband and Waits (2020; 0.76 43 ) for Idaho’s wolf population although their estimate did not include the 357 pups that I present here. The observed heterozygosity in Idaho’s reintroduced population of wolves was similar to values reported from other recovering wolf populations 44 46 .…”

“…Statewide harvest data from Idaho Department of Fish and Game indicated harvest did increase from 2017 to 2018, however. Genotyping of tissue samples from harvested wolves also indicated the harvest rate increased from 2016 to 2017 (11.2%) to the 2017–2018 season (25.5%; Ausband & Waits, 2020). The available data suggest there were indeed fewer wolves in our study areas in 2018 compared to previous years.…”

“…Our study exemplifies how a high turnover of territorial individuals caused by humans affects age at first reproduction. The overall impact of humans on large carnivore population size [ 23 , 52 ], distribution [ 24 , 67 ], genetic diversity [ 73 ] and reproductive success [ 74 ] through legal harvest and illegal hunting highlights the need of accurate estimates of life-history traits when managing small carnivore populations in human-dominated landscapes.…”
