Mitogenomic phylogenetic analyses of Leptogorgia virgulata and Leptogorgia hebes (Anthozoa: Octocorallia) from the Gulf of Mexico provides insight on Gorgoniidae divergence between Pacific and Atlantic lineages

Ecology and Evolution, 2019
The use of genetics in recent years has brought to light the need to reevaluate the classification of many gorgonian octocorals. This study focuses on two Leptogorgia species—Leptogorgia virgulata and Leptogorgia hebes—from the northwestern Gulf of ...

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.

Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

Journal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

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
