Phylogeographic analysis revealed allopatric distribution pattern and biogeographic processes of the widespread pale chub Opsariichthys acutipinnis-evolans complex (Teleostei: Cyprinidae) in southeastern China

Frontiers in Ecology and Evolution, 2023
Understanding phylogeographic patterns of widespread species can provide insights into their speciation processes and guide the conservation and management measures.

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

Journal of Fish Biology, EarlyView.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Genetic footprints of Quaternary glacial cycles over the patterns of population diversity and structure in three Nacella (Patellogastropoda: Nacellidae) species across the Magellan province in southern South America

Frontiers in Marine Science, 2023
Quaternary glaciations severely altered landscape/seascape at high latitudes and had major consequences on species geographical ranges, population sizes, genetic differentiation and speciation rates.

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 ...

Striking Suture Zone Mismatch Between Nuclear and Mitochondrial Markers in North African Chalcides ocellatus (Squamata: Scincidae)

Zoologica Scripta, EarlyView.
ABSTRACT Linnaean and Wallacean shortfalls remain pervasive even among common and widespread Mediterranean taxa, limiting our understanding of evolutionary history and species boundaries. The Ocellated Skink Chalcides ocellatus complex illustrates this issue, with disputed subspecific taxonomy and deep mitochondrial divergences across North Africa and ...

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

Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

Zoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

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.
