Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

Optimizing genetic diversity in Australian Holsteins and Jerseys: A comparative analysis of whole-genome and regional inbreeding depression effects

Journal of Dairy Science
: Homozygosity, which can arise from several genetic mechanisms including inbreeding, is frequently observed in the offspring of related parents. This inbreeding can lead to a reduced performance, owing to a phenomenon known as inbreeding depression ...

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

Animal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

Inbreeding depression for producer-recorded udder, metabolic, and reproductive diseases in US dairy cattle

Journal of Dairy Science
: This study leveraged a growing dataset of producer-recorded phenotypes for mastitis, reproductive diseases (metritis and retained placenta), and metabolic diseases (ketosis, milk fever, and displaced abomasum) to investigate the potential presence of ...

A century of theories of balancing selection

Biological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Trends in genetic diversity and the effect of inbreeding in American Angus cattle under genomic selection

Genetics Selection Evolution, 2021
Background While the adoption of genomic evaluations in livestock has increased genetic gain rates, its effects on genetic diversity and accumulation of inbreeding have raised concerns in cattle populations.

Inbreeding depression and outbreeding depression in plants [PDF]

Heredity, 1996
The genetic mechanism underlying an ‘Optimal outcrossing distance’ in plants (sensu Price and Waser) is discussed. Monte Carlo simulations of a population subdivided as a one-dimensional stepping-stone are used to evaluate possible genetic mechanisms.

Introduced mona monkey Cercopithecus mona is a key predator of bird nests in the endemic‐rich Príncipe Island

Conservation Science and Practice, EarlyView.
Abstract Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal species.

Bottlenecks and inbreeding depression in autotetraploids

Evolution, 2018
Inbreeding depression is dependent on the ploidy of populations and can inhibit the evolution of selfing. While polyploids should generally harbor less inbreeding depression than diploids at equilibrium, it has been unclear whether this pattern holds in non-equilibrium conditions following bottlenecks.
