A multivariate analysis with direct additive and inbreeding depression load effects

Genetics Selection Evolution, 2019
Background Inbreeding is caused by mating between related individuals and its most common consequence is inbreeding depression. Several studies have detected heterogeneity in inbreeding depression among founder individuals, and recently a procedure for ...

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Inbreeding, inbreeding depression, and infidelity in a cooperatively breeding bird.

Evolution; international journal of organic evolution, 2018
Inbreeding depression plays a major role in shaping mating systems: in particular, inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction in socially monogamous species. This suggestion relies on assumptions that are rarely comprehensively tested: that inbreeding depression is present, that higher kinship between ...

Quantification of human‐caused mortality in an imperiled turtle

Wildlife Biology, EarlyView.
For many threatened and endangered species, the importance of human‐caused mortality relative to other sources has not been quantified, making it difficult to assess the effectiveness of mortality‐reduction strategies. We used radio telemetry data, pooled across studies at protected sites in the US states of Illinois and Wisconsin, to estimate natural ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, EarlyView.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, 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.

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, EarlyView.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Correlation Analysis among the Various Inbreeding Coefficients of Pannon Ka Rabbits

Diversity
In a closed population with a limited population size, mating of related animals is unavoidable. In this study, the genealogy data of a synthetic maternal rabbit breed called Pannon Ka were used to calculate different inbreeding coefficients.

Incestuous sisters: mate preference for brothers over unrelated males in Drosophila melanogaster.

PLoS ONE, 2012
The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny.

All roads lead to infection: A mechanistic model to assess transmission routes of brucellosis in a wild ungulate population

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildlife and domestic populations frequently share diseases with a potential for cross‐species transmission, posing significant threats to animal and human health, economy and biodiversity conservation.
