Perspectives of genomics for genetic conservation of livestock [PDF]

open access: yes, 2011
Genomics provides new opportunities for conservation genetics. Conservation genetics in livestock is based on estimating diversity by pedigree relatedness and managing diversity by choosing those animals that maximize genetic diversity.

Determinants of genetic diversity [PDF]

open access: yesNature Reviews Genetics, 2016
Genetic polymorphism varies among species and within genomes, and has important implications for the evolution and conservation of species. The determinants of this variation have been poorly understood, but population genomic data from a wide range of organisms now make it possible to delineate the underlying evolutionary processes, notably how ...

The Genetic Diversity of the Americas [PDF]

open access: yesAnnual Review of Genomics and Human Genetics, 2017
The history of the Americas involved the encounter of millions of Native Americans, Europeans, and Africans. A variable admixture of these three continental groups has taken place throughout the continent, influenced by demography and a range of social factors.

Chytrid fungus infection in alpine tree frogs is associated with individual heterozygosity and population isolation but not population-genetic diversity [PDF]

open access: yes, 2020
Chytridiomycosis, a disease caused by the emerging fungus Batrachochytrium dendrobatidis (Bd), has been implicated in the decline of over 500 amphibian species.

Maize Germplasm Conservation in Southern California's Urban Gardens: Introduced Diversity Beyond ex situ and in situ Management. [PDF]

open access: yes, 2016
Contemporary germplasm conservation studies largely focus on ex situ and in situ management of diversity within centers of genetic diversity. Transnational migrants who transport and introduce landraces to new locations may catalyze a third type of ...

Global to local genetic diversity indicators of evolutionary potential in tree species within and outside forests [PDF]

open access: yes, 2014
There is a general trend of biodiversity loss at global, regional, national and local levels. To monitor this trend, international policy processes have created a wealth of indicators over the last two decades.

Environmental factors influence both abundance and genetic diversity in a widespread bird species. [PDF]

open access: yes, 2013
Genetic diversity is one of the key evolutionary variables that correlate with population size, being of critical importance for population viability and the persistence of species. Genetic diversity can also have important ecological consequences within

Does habitat stability structure intraspecific genetic diversity? It’s complicated... [PDF]

open access: yes, 2020
Regional phylogeographic studies have long been conducted in the southeastern United States for a variety of species. With some exceptions, many of these studies focus on single species or single clades of organisms, and those considering multiple ...

Recombination and Genetic Diversity

open access: yesTrends in Computational and Applied Mathematics, 2012
In this paper we present a spatial stochastic model for genetic recombination, that answers if diversity is preserved in an infinite population of recombinating individuals distributed spatially. We show that, for finite times, recombination may maintain all the various potential different types, but when time grows infinitely, the diversity of ...

Benefits of host genetic diversity for resistance to infection depend on parasite diversity [PDF]

open access: yes, 2010
Host populations with high genetic diversity are predicted to have lower levels of infection prevalence. This theory assumes that host genetic diversity results in variation in susceptibility and that parasites exhibit variation in infectivity. Empirical
