Practice-oriented controversies and borrowed epistemic support in current evolutionary biology: phylogeography as a case study. [PDF]
Although there is increasing recognition that theory and practice in science are often inseparably intertwined, discussions of scientific controversies often continue to focus on theory, and not practice or methodologies.

Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

The Intercontinental phylogeography of neustonic daphniids [PDF]
AbstractOrganisms that live at the freshwater surface layer (the neuston) occupy a high energy habitat that is threatened by human activities. Daphniids of the genera Scapholeberis and Megafenestra are adapted to the neuston but are poorly studied for biogeography and diversity. Here we assess the global phylogeography of neustonic daphniids.

Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Bacillus anthracis Phylogeography: New Clues From Kazakhstan, Central Asia
This article describes Bacillus anthracis strains isolated in Kazakhstan since the 1950s until year 2016 from sixty-one independent events associated with anthrax in humans and animals.

Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Human phylogeography and diversity [PDF]
Homo sapiens phylogeography begins with the species’ origin nearly 200 kya in Africa. First signs of the species outside Africa (in Arabia) are from 125 kya. Earliest dates elsewhere are now 100 kya in China, 45 kya in Australia and southern Europe (maybe even 60 kya in Australia), 32 kya in northeast Siberia ...

Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

The high mountain ranges of Western Europe had a profound effect on the biotic recolonization of Europe from glacial refugia. The Alps present a particularly interesting case because they form an absolute barrier to dispersal for most taxa, obstructing ...

Abstract In well‐studied groups of organisms, the taxonomic landscape can be very complex, with several alternative classifications describing diversity within the same set of populations. For example, three hypotheses have previously been proposed to describe the taxonomy of the common and widespread Eurasian Dusky Meadow Brown butterfly, Hyponephele ...
