Actualidades 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.

Ecology and Evolution, Volume 16, Issue 7, July 2026.We use comparative genomic comparisons between species and subspecies in a north temperate fish to examine the relationship between inferred divergence time and extent of reproductive isolation. We found that similar divergence times were associated with dramatically distinct levels of reproductive isolation.

European 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.

Ecology and Evolution, Volume 16, Issue 7, July 2026.The genomic and chromosomal organization of C. nutans was investigated using GISH and ND‐FISH with four oligonucleotide probes. The results showed that repetitive sequence distribution exhibited genome‐specific patterns: the H genome demonstrated high structural stability with low polymorphism, while the St genome showed moderate variation, and the Y ...

, 2018 The cytosolic sulfotransferase (SULT) SULT2A1 is known to mediate the sulfation of DHEA as well as some other hydroxysteroids such as pregnenolone. The present study was designed to investigate how genetic polymorphisms of the human SULT2A1 gene may ...

Genetic characterization of the Balkan endemic species, Merodon desuturinus (Diptera: Syrphidae)
European Journal of Entomology, 2008 Variation of 15 nuclear allozyme genes and a 708 bp fragment of DNA sequence of the mitochondrial cytochrome c oxidase subunit I (COI) gene were surveyed in a population of a hoverfly species, Merodon desuturinus Vujić, Šimić & Radenković, 1995 (Diptera,

Plant 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).

Revista Chilena de Historia Natural, 2002 Pines have been the focus of several studies that estimate population genetic parameters using both allozymes and chloroplast single sequence repeats (SSRs). Also, the genus has also been recently studied using molecular systematics so that we now have a
