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

Genetics 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 ...

Global evolution and phylogeography of Brucella melitensis strains

BMC Genomics, 2018
Brucellosis is a bacterial zoonotic disease. Annually in the world more than 500,000 new cases of brucellosis in humans are registered. In this study, we propose an evolutionary model of the historical distribution of B.

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

Zoologica Scripta, EarlyView.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Candida auris Infection Leading to Nosocomial Transmission, Israel, 2017

Emerging 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.

Phylogeography of Puumala orthohantavirus in Europe

Viruses, 2019
Puumala virus is an RNA virus hosted by the bank vole (Myodes glareolus) and is today present in most European countries. Whilst it is generally accepted that hantaviruses have been tightly co-evolving with their hosts, Puumala virus (PUUV) evolutionary ...

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Prediction of the Spatial Origin of Puumala Virus Infections Using L Segment Sequences Derived from a Generic Screening PCR

Viruses, 2019
To screen diagnostic specimens for the presence of hantavirus genomes or to identify new hantaviruses in nature, the pan-hanta L-PCR assay, a broadly reactive nested reverse transcription polymerase chain reaction (RT-PCR) assay targeting the L segment ...

Evidence for survival of Pleistocene climatic changes in Northern refugia by the land snail Trochoidea geyeri (Soós 1926) (Helicellinae, Stylommatophora) [PDF]

, 2003
The study of organisms with restricted dispersal abilities and presence in the fossil record is particularly adequate to understand the impact of climate changes on the distribution and genetic structure of species.

Genome‐Wide Analysis Successfully Resolves Population Structure Shaped by Recent Divergence in the Endangered Bagrid Catfish Pseudobagrus ichikawai

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Using genome‐wide SNP data, we revealed previously undetected population structure in the endangered bagrid catfish Pseudobagrus ichikawai. Our results suggest that past paleo‐river systems shaped the current genetic connectivity across the Ise Bay area, while low genetic diversity indicates historical bottlenecks and recent inbreeding.
