Genetic Diversity in Dutch Sheep Breeds

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT The Netherlands has a rich variety of native sheep breeds, most of them at risk or endangered. We studied the distinctiveness of these breeds, their genetic diversity within and between breeds, and how this diversity is shaped by geography, purpose, history and genetic management practices.

Mitochondrial Markers COI and 16S rRNA for the Molecular Identification of Parrots and Macaws Recovered From Illegal Trafficking in Three Areas of Colombia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We molecularly characterized parrots (Amazona spp.) and macaws (Ara spp.) rescued from illegal trafficking in Colombia using two mitochondrial markers (COI and 16S rRNA). The COI gene showed high resolution for species identification and revealed considerable intraspecific diversity, while 16S rRNA displayed limited taxonomic resolution.

Introgression of trypanotolerance genes

Trypanosomosis is the most widespread parasitic disease of great importance in Africa affecting human and animals. There are breeds of cattle that are trypanotolerant. Trypanotolerance is an ability of these breeds to withstand the effects of trypanosome infections. The disease impedes production in Sub-Saharan Africa. In this thesis, the main focus is

Incomplete lineage sorting and hybridization as sources of gene tree discordance among species of the Geminata clade of Solanum (Solanaceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Discordance among gene trees, including discrepancies with the species tree, is increasingly reported in analyses of phylogenomic data. Such discordance can result from technical issues such as misalignment, paralogy, or model misfit, or from biological processes such as incomplete lineage sorting (ILS), hybridization with introgression, or ...

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Reliable Inference of Phylogenomic Relationship via Assembly‐Based Strategy Accommodating Raw Reads and Proteins

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Phylogenomics is a transformative approach in systematics, conservation biology, and biomedical research, enabling the inference of evolutionary relationships by leveraging hundreds to thousands of genes from genomic or transcriptomic data. However, acquiring high‐quality genomes and transcriptomes necessitates samples with intact DNA and RNA,
