Phylogenomic history of enigmatic pygmy perches: implications for biogeography, taxonomy and conservation [PDF]

Royal Society Open Science, 2018
Pygmy perches (Percichthyidae) are a group of poorly dispersing freshwater fishes that have a puzzling biogeographic disjunction across southern Australia. Current understanding of pygmy perch phylogenetic relationships suggests past east–west migrations

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Lineage Diversification and Population Dynamics of the Qinghai Toad-Headed Agama (Phrynocephalus vlangalii) on the Qinghai–Tibet Plateau, with Particular Attention to the Northern Slope of the Kunlun–Arjin Mountains

Animals
The Kunlun, Arjin, and Qilian mountain ranges mark the northern edge of the Qinghai–Tibet Plateau (QTP), where rapid uplift and Quaternary glacial cycles have shaped a unique cold desert ecosystem and species distribution.

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

Ecology 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 ...

A statistical phylogeography of influenza A H5N1 [PDF]

Proceedings of the National Academy of Sciences, 2007
The geographic diffusion of highly pathogenic influenza A H5N1 has largely been traced from the perspective of the virus's victims. Birds of a variety of avian orders have been sampled across localities, and their infection has been identified by a general genetic test.

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Considerations and distributional innovations for some taxa of the genus Parapholis (Poaceae) in the Adriatic basin with special reference to Parapholis strigosa, for which a new infraspecific taxon is proposed

Natural History Sciences
The distribution of Parapholis strigosa (Dumort.) C.E.Hubb. in the Adriatic basin has been analysed. After the investigations by Hylander and Runemark, further collections were made, particularly during the years 1991-2002, and in 2017-2018 limited to ...

A novel taxon selection method, aimed at minimizing recombination, clarifies the discovery of a new sub‐population of Helicobacter pylori from Australia

Evolutionary Applications, 2020
We present a novel method for taxon selection, the aim being to minimize problems arising from highly recombinant species such as Helicobacter pylori.
