Phylogeography and Contact Zones of the Common Grass Snake in Poland (Squamata: Natricidae: Natrix natrix)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 209-219, March 2026.
ABSTRACT Until now, the genetic identity of common grass snakes (Natrix natrix) in Poland remained poorly understood. This study presents the first comprehensive phylogeographic analysis for Poland using mitochondrial DNA sequences (cyt b and ND4 + tRNAs) and 13 nuclear microsatellite loci.

First insight of genetic diversity, phylogeographic relationships, and population structure of marine sponge Chondrosia reniformis from the eastern and western Mediterranean coasts of Tunisia

open access: yesEcology and Evolution, 2022
Despite the strategic localization of Tunisia in the Mediterranean Sea, no phylogeographic study on sponges has been investigated along its shores. The demosponge Chondrosia reniformis, descript only morphologically along Tunisian coasts, was chosen to ...

Conservation of the critically endangered frog Telmatobufo bullocki in fragmented temperate forests of Chile : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Conservation Biology at Massey University, Albany, New Zealand [PDF]

open access: yes, 2015
Amphibians are currently facing several threats and are suffering severe population declines and extinction worldwide. Telmatobufo bullocki (Anura: Calyptocephalellidae) is one of the rarest and most endangered amphibian species in Chile's temperate ...

Coalescent-based species delimitation in the sand lizards of the Liolaemus wiegmannii complex (Squamata: Liolaemidae) [PDF]

open access: yes, 2019
Coalescent-based algorithms coupled with the access to genome-wide data have become powerful tools forassessing questions on recent or rapid diversification, as well as delineating species boundaries in the absence of reciprocal monophyly.

Multiple Glacial Refugia and Complex Postglacial Dynamics of Primula sikkimensis (Primuaceae) in the Heterogeneous Qinghai‐Tibet Plateau

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

Testing the Rio Doce as a riverine barrier in shaping the Atlantic rainforest population divergence in the rodent Akodon cursor

open access: yesGenetics and Molecular Biology, 2010
Akodon cursor occurs in dense rainforest from northern (8º S) to southern (26º S) states along the Atlantic coast of Brazil. Previous karyological and molecular data revealed two major clades, one including northern (8-15º S) and the other southern (19 ...

Multilocus Phylogeny of Asiatic Striped Squirrels (Sciuridae, Tamiops) Reveals Their Evolutionary Relationships and Species Limits

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The genus Tamiops has long been underestimated in terms of species diversity due to reliance on seasonal fur coloration. This study integrates mitochondrial whole‐genome and nuclear gene data to identify seven monophyletic lineages, elevating T. maritimus hainanus to independent species status.

Candida auris Infection Leading to Nosocomial Transmission, Israel, 2017

open access: yesEmerging Infectious Diseases, 2018
A patient transferred from South Africa to Israel acquired a Candida auris infection. Phylogenetic analysis showed resemblance of C. auris to isolates from South Africa but not Israel, suggesting travel-associated infection. C.

Age of innovation: Progress in systematic botany in the 20th century

open access: yesTAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Systematic botany can be regarded as the oldest of the botanical sciences, having originated with the ancient Greeks. Although much progress has been achieved in systematic botany over nearly two millennia, in the 20th century, many significant innovations took place in revealing processes of evolution, principles and methods of classification,
