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.

3RAD‐Guided SNP Discovery for Species Identification and Conservation of the Medicinal Southern African Tree Genus Greyia Hook. & Harv.

Ecology and Evolution, Volume 16, Issue 5, May 2026.
A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...

Assessing Genetic Diversity and Inbreeding Effects in an Endangered Amphibian: Effects of Ecological Restoration and Stochasticity

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluated the genetic health of the endangered Rawlinsonia littlejohni following habitat modification and climatic variability. We identified two genetically distinct sub‐populations separated by limited gene flow, with heterozygosity remaining higher and inbreeding lower in the northern sub‐population containing both natural and constructed

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

Conspecific Scaffold‐Level Genome Assembly Outperforms Heterospecific Chromosome‐Level Assemblies for Assessing Genetic Indicators in a Threatened Marine Fish

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Understanding the genomic architecture of species of conservation concern is essential for fostering effective conservation initiatives. Current biodiversity assessment approaches increasingly incorporate genetic metrics to evaluate the status of species and populations of conservation interest.

Population Genomics Reveals Genetic Diversity, Introgression, and Genetic Differentiation in Tianshan Mountains Western Honeybees (Apis mellifera)

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT The Tianshan Mountains, which host two native subspecies of western honeybees, represent the easternmost natural distribution limit of Apis mellifera. The managed Xinjiang black honeybee (XJ), introduced a century ago and designated as a Chinese National Animal Genetic Resource, has expanded rapidly under anthropogenic management.
