Modeling long‐term population viability to inform recovery of a functionally extinct urban Blanding's turtle population

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
We used a population viability analysis to evaluate the influence of headstarting on recovery of the Rouge National Urban Park Blanding's turtle population. Completing the remaining 12 years of the 20‐year headstarting program is projected to approximately double population size relative to no further supplementation.

Mothers Matter Most: Maternal, but Not Paternal, Age and Inbreeding Affect Nestling Telomere Length in a Wild Passerine. [PDF]

Mol Ecol
ABSTRACT Early‐life telomere length can be an integrated and accessible biomarker of lifetime fitness. Telomere length can result from complex interactions between heritable genetic variation, inherited gametic variation and accumulated environmental effects acting on individuals and parents.

Multidisciplinary Evaluation of a 10‐Year Restoration Program for Two Endangered Atlantic Salmon (Salmo salar) Populations

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Supportive breeding programs are widely implemented to counteract demographic collapse in threatened populations. Their long‐term success, however, depends on maintaining genetic diversity while ensuring that released individuals contribute effectively to wild populations.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Maximizing Genetic Response in Breeding Schemes of Dairy Cattle with Constraints on Variance of Response

, 1994
Predicted genetic progress in dairy cattle breeding schemes was maximized with the variances of selection responses constrained, i.e., restricted effective population sizes. This restriction would also lead to schemes with acceptable rates of inbreeding (

Estimation of the Inbreeding Coefficient through Use of Genomic Data

, 2003
Many linkage studies are performed in inbred populations, either small isolated populations or large populations with a long tradition of marriages between relatives. In such populations, there exist very complex genealogies with unknown loops. Therefore,

Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 535-559, July 2026.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A, creating matrix AΓ. Commonly metafounders are defined based on the available information of the animal (e.g., country, sex, breed) similar to unknown parent

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 ...

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 602-612, July 2026.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

Journal of Applied Entomology, Volume 150, Issue 6, Page 736-742, July 2026.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.
