Generation Length: Often Ignored and Sometimes Misunderstood

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Traditional mathematical models of population genetics have generally assumed discrete generations, but most species have overlapping generations. It is necessary to estimate generation length with overlapping generations for purposes of comparison with discrete‐generation models.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 508-523, July 2026.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Ancestral relationships using metafounders: Finite ancestral populations and across population relationships. [PDF]

, 2022
.Recent use of genomic (marker-based) relationships shows that relationships exist within and across base population (breeds or lines). However, current treatment of pedigree relationships is unable to consider relationships within or across base ...

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

Genomic Structure and Demographic History of the Brown Fur Seal: From the Ice Age to Current Isolation

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Arctocephalus pusillus (the brown fur seal) has historically experienced population fluctuations associated with glacial cycles and anthropogenic exploitation. Previous mitochondrial DNA (mtDNA) and microsatellite analyses suggested a post‐glacial population expansion in A.

Population Genomics Highlight the Vulnerability of Coral‐Dwelling Gobies to Ecological Losses due to Climatic Disturbances

Molecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT Predicting species resilience to climate change generally focuses on species life history and ecology, overlooking genomic changes following disturbances. After consecutive cyclones and heatwaves, coral‐dwelling Gobiodon gobies have experienced extreme population and group size reductions, and slower recovery rates than their coral hosts.

Genomic Offsets Predict Survival With Low Accuracy in a Marine Common Garden

Molecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT Predicting how populations will respond to climate change is an urgent priority in evolutionary and conservation biology. Genetic and environmental influences have long been known to impact responses to shifting climates, giving rise to the development of genomic offset methods that attempt to predict the degree of maladaptation following ...

Short communication: The importance of random effects in detecting purging of inbreeding depression: A model comparison in Pannon White rabbits

Animal
Inbreeding depression (ID) is a well-documented phenomenon associated with reduced fitness and possible extinction. However, ID can be mitigated or even eliminated through the interplay of inbreeding and selection, a process known as purging.
