Flowcytometric and Allozymic Studies on the Korean Dandelion (Taraxacum, Asteraceae), With Special Reference to the Hybrid Origin of Taraxacum coreanum Nakai

open access: yesPlant Species Biology, Volume 41, Issue 4, July 2026.
We found that the Korean tetraploid Taraxacum coreanum (Co) shows fixed heterozygosity at two dimeric enzyme loci, sod‐1 (aaab) and mdh‐1 (bddd). Allele‐specific comparisons indicate that sod‐1 ‘a’ and mdh‐1 ‘d’ are characteristic of the triploid T. mongolicum (Mo) whereas the ‘b’ alleles at both loci match Korean diploids (e.g., T. hallaisanense, Ha).

Allozyme variation in Czech populations of the invasive spiny-cheek crayfish Orconectes limosus (Cambaridae) [PDF]

open access: yesKnowledge and Management of Aquatic Ecosystems, 2009
The North American spiny-cheek crayfish, Orconectes limosus, was most probably introduced into Europe only once, in 1890. The size of the founding population was just 90 individuals.

A Practical Framework for GT‐Seq Panel Optimization

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Genotyping‐in‐thousands by sequencing (GT‐seq) panels are powerful tools in ecological, evolutionary and conservation genomics, yet the optimization process critical for robust and reproducible genotyping remains poorly formalized. Here, we present an iterative workflow for GT‐seq panel optimization that emphasizes systematic refinement ...

Genomic Insights Into Population Structure and Demographic History of White Anglerfish (Lophius piscatorius) Throughout Its Range

open access: yesEvolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Understanding population structure and clarifying species boundaries are essential for the sustainable management of exploited marine species. Although genomic resources for shallow‐water taxa have expanded rapidly, open‐water species remain comparatively understudied.

GENETIC VARIABILITY IN THE MAGDALENA RIVER TURTLE, PODOCNEMIS LEWYANA (DUMÉRIL, 1852), IN THE MOMPOS DEPRESSION, COLOMBIA VARIABILIDAD GENÉTICA DE LA TORTUGA DEL RÍO MAGDALENA, PODOCNEMIS LEWYANA (DUMÉRIL, 1852), EN LA DEPRESIÓN MOMPOSINA, COLOMBIA

open access: yesActualidades Biológicas, 2008
Two populations of the endangered Magdalena River turtle, Podocnemis lewyana, separated by 55 km in the Mompos Depression were sampled to quantify levels of genetic variation and inspect for evidence of genetic structure.

Characterizing the Distribution of Oncorhynchus mykiss Genetic Diversity in the Klamath River Basin Before Dam Removal

open access: yesEvolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Genetic assessments serve as powerful tools to evaluate the effects of anthropogenic habitat fragmentation on natural populations. In the Klamath River Basin, construction of four dams from 1912 to 1962 had a profound impact on the distribution of anadromous fishes, blocking access to over 751 river kilometers of critical habitat.

ALLOZYME DIVERSITY IN THEOBROMA CACAO

open access: yesHortScience, 1993
Theobroma cacao is a morphologically diverse species. To understand variation within species, gene diversity estimates for a germplasm collection were calculated from allozyme data. Of nine enzymes assayed, six enzymes encoded by nine loci were found to be polymorphic.

Phylogeny of Cutthroat Trout (Oncorhynchus clarkii) Based on Full Mitochondrial Genomes With Comments on Species Delimitation and Taxonomy

open access: yesEvolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Despite the important role that species concepts and taxonomy play in understanding the evolution of species, taxonomists have struggled to describe the relationship between many organisms. Here, using Cutthroat Trout as a case study, we illustrate how full mitochondrial genomes and broad taxonomic sampling can provide further insight on ...

Phylogenetic relationships among social parasites and their hosts in the ant tribe Tetramoriini (Hymenoptera: Formicidae)

open access: yesEuropean Journal of Entomology, 2000
The phylogenetic relationships among Palaearctic species of the ant genus Tetramorium and its social parasites of the genera Strongylognathtus, Anergates and Teletomyrmex, were investigated electrophoretically at 21 presumptive enzyme loci.
