Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

Wildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.

Management of Genetic Diversity in the Era of Genomics

Frontiers in Genetics, 2020
Management of genetic diversity aims to (i) maintain heterozygosity, which ameliorates inbreeding depression and loss of genetic variation at loci that may become of importance in the future; and (ii) avoid genetic drift, which prevents deleterious ...

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, EarlyView.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Lifetime Fitness Costs of Inbreeding and Being Inbred in a Critically Endangered Bird.

Current Biology, 2019
Reduced fitness as a result of inbreeding is a major threat facing many species of conservation concern [1-4]. However, few case studies for assessing the magnitude of inbreeding depression in the wild means that its relative importance as a risk factor ...

First Vasectomy Procedure Successfully Performed on a Southern African Male Giraffe (Giraffa camelopardalis giraffa)

Zoo Biology, EarlyView.
First successful vasectomy in a southern African male giraffe, Giraffa camelopardis giraffa ABSTRACT This study reports the first successful vasectomy on a southern African male giraffe (Giraffa camelopardalis giraffa). The goal of the procedure was to create a teaser male for reproductive studies.

Symposium review: The genomic architecture of inbreeding: How homozygosity affects health and performance.

Journal of Dairy Science, 2019
Inbreeding depression is a growing concern in livestock because it can detrimentally affect animal fitness, health, and production levels. Genomic information can be used to more effectively capture variance in Mendelian sampling, thereby enabling more ...

Eco‐evolutionary dynamics of partially migratory metapopulations in spatially and seasonally varying environments

Journal of Animal Ecology, EarlyView.
Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...

Removing exogenous information using pedigree data

, 2011
Management of certain populations requires the preservation of its pure genetic background. When, for different reasons, undesired alleles are introduced, the original genetic conformation must be recovered.

History and structure of the closed pedigreed population of Icelandic Sheepdogs [PDF]

, 2009
Background - Dog breeds lose genetic diversity because of high selection pressure. Breeding policies aim to minimize kinship and therefore maintain genetic diversity.
