Inbreeding and coancestry trends in Nordic Holstein

, 2022
Increased rates of inbreeding have been observed in several Holstein populations across the world since genomic selection (GS) was implemented into the breeding programs. The objective of this study was to test whether this is also the case in the Nordic Holstein population using pedigree data.

Using of relatedness and heritability in a Eucalyptus benthamii trial for conservation and breeding

Crop Breeding and Applied Biotechnology, 2023
We evaluated the genetic diversity, coancestry and heritability of an E. benthamii trial. The 115 individuals were genotyped (13 SSR) and had their height and diameter at breast height (dbh) measured.

Does Functionality Condition the Population Structure and Genetic Diversity of Endangered Dog Breeds under Island Territorial Isolation?

Animals, 2020
Despite the undefinition of the origins of Ca de Rater (CR) and Ca de Bestiar (CB) dogs, references to these endangered autochthonous breeds highlighted their ratting/pet and shepherding/guard skills for centuries.

Combining Multiple Genetic Estimates of Ne

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Researchers often use multiple genetic methods to estimate contemporary effective population size (Ne), but few formally combine estimates despite potential benefits for increasing precision. Maximising benefits requires an optimal, inverse‐variance weighting scheme.

Change in genetic size of small-closed populations: lessons from a domestic mammal population

Genetics and Molecular Biology, 2010
The aim of this study was to monitor changes in genetic size of a small-closed population of Iranian Zandi sheep, by using pedigree information from animals born between 1991 and 2005.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

Animal Conservation, Volume 29, Issue 2, Page 136-145, April 2026.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

Paternity of Western Gray Whales Feeding Off Sakhalin Island, Russia

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT While understanding mating systems can provide critical insight into a population's long‐term persistence and resilience, such information remains limited for most baleen whales. However, extensive research on the western gray whales that feed off Sakhalin Island, Russia, led to the collection of biopsy samples from 75% of the 207 whales photo‐

Effect of linkage on the control of inbreeding in selection programmes

Genetics Selection Evolution, 2000
Selection and mating methods for controlling inbreeding in selection programmes are based on relationships obtained from pedigrees. The efficiency of these methods has always been tested by studies using genetic models of independent loci. However, under

Pleistocene Divergence and Long‐Term Population Decline in Three Endemic Euphorbia Species of High Conservation Concern From the South‐Western Alps and the Mountains of Corsica and Sardinia

Diversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Understanding the evolutionary history and demographic dynamics of narrow‐ranged endemics is essential for predicting their future under climate change. We investigated the origins, population trajectories, and conservation outlook of three endemic spurges (Euphorbia gayi, E. valliniana, E. variabilis) restricted to the south‐western Alps,
