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

open access: yesAnimal 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.

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

open access: yesAnimal 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 affecting stayability in Italian Holstein cows

open access: yesJournal of Dairy Science
: Advances in selection and reproduction methods, particularly the implementation of genomic evaluations alongside assisted reproductive technologies, have substantially enhanced productivity and efficiency, notably within specialized dairy cattle ...

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

open access: yesAnimal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

open access: yesAnimal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...

EFFECT OF INBREEDING ON MORTALITY OF CAPTIVE TIGER [PDF]

open access: yesExploratory Animal and Medical Research, 2017
A study was carried out on the captive tigers of Nandankanan zoo, Odisha, India, to conclude any deleterious effect of inbreeding on mortality. A pedigree path analysis of 342 tigers was done to estimate the inbreeding coefficient of each tiger from ...

Tipping the Scales Using Cryopreservation: Modelling the Genetic Value and Management Potential of Integrated Cryopreservation for Threatened Ex‐Situ Pupfish Populations

open access: yesAnimal Conservation, EarlyView.
This graphical abstract depicts the number of additional fish that would be required to achieve 90% genetic diversity for endangered pupfish species housed in EAZA collections, with or without the use of cryopreserved material. ABSTRACT Zoos and aquaria must retain genetic diversity for the species they house if the populations are to remain viable ...

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.
