Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly

Ecological Entomology, EarlyView.
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

Genetic Diversity and Impacts of Stocking on Cyprinus carpio Populations in Türkiye: Insights From Mitochondrial, Nuclear, and Microsatellite Markers

Fisheries Management and Ecology, EarlyView.
ABSTRACT Understanding genetic diversity and population structure is essential for the sustainable management of widely stocked freshwater species such as common carp (Cyprinus carpio). In this study, we conducted a comprehensive genetic assessment of C.

Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.

Genomic measures of inbreeding in the Norwegian–Swedish Coldblooded Trotter and their associations with known QTL for reproduction and health traits

Genetics Selection Evolution, 2019
Background Since the 1950s, the Norwegian–Swedish Coldblooded trotter (NSCT) has been intensively selected for harness racing performance. As a result, the racing performance of the NSCT has improved remarkably; however, this improved racing performance ...

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

Insect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.

Assessing different metrics of pedigree and genomic inbreeding and inbreeding effect on growth, fertility, and feed efficiency traits in a closed-herd Nellore cattle population

BMC Genomics
Background The selection of individuals based on their predicted breeding values and mating of related individuals can increase the proportion of identical-by-descent alleles.

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

Insect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Comprehensive analysis of inbreeding depression across growth, fertility, and survival traits in Limousine beef cattle

Animal
The Italian Limousine cattle population, with approximately 100 000 registered animals in the national herd book, plays a crucial role in the country’s national beef industry, being one of the most widely spread breeds in Italy.

Genomic diversity dynamics in conserved chicken populations are revealed by genome-wide SNPs

BMC Genomics, 2018
Background Maintaining maximum genetic diversity and preserving breed viability in conserved populations necessitates the rigorous evaluation of conservation schemes.
