Nucleotide sequences of mitochondrial cytochrome b gene for phylogeny of some species of Rodentia

open access: yesBioscience Journal, 2023
Order Rodentia contains approximately half of all living mammalian species. Most of the living species diversity within rodents is within five monophyletic radiations: Hystricognathi, Sciuridae, Geomyoidea, Dipodidae, and Muroidea.

Population genomic analysis of the Speckled Dace species complex identifies three distinct lineages in California

open access: yesTransactions of the American Fisheries Society, Volume 151, Issue 6, Page 695-710, November 2022., 2022
Abstract Objective Speckled Dace Rhinichthys osculus is small cyprinoid fish that is widespread in western North America. In California and elsewhere it is currently treated as a single species with multiple subspecies, many undescribed. However, these subspecies may represent evolutionary lineages that are cryptic species because they cannot be ...

Tip dating supports novel resolutions of controversial relationships among early mammals [PDF]

open access: yes, 2020
The estimation of the timing of major divergences in early mammal evolution is challenging due to conflicting interpretations of key fossil taxa. One contentious group is Haramiyida, the earliest members of which are from the Late Triassic.

Phylogenomics and generic limits of Dypsidinae (Arecaceae), the largest palm radiation in Madagascar

open access: yesTAXON, Volume 71, Issue 6, Page 1170-1195, December 2022., 2022
Abstract With 178 species, palm subtribe Dypsidinae is one of the largest plant radiations on Madagascar. A well‐resolved species‐level phylogeny is required not only to unpick the drivers of this spectacular radiation, but also to define natural and useful generic limits in this taxonomically difficult group.

Molecular phylogeny of Lichen Tiger Moths (Lepidoptera, Erebidae, Arctiinae, Lithosiini): a contribution toward classifying Western Hemisphere genera [PDF]

open access: yesZooKeys, 2022
This study analyzes molecular sequence data from one mitochondrial (COI) and two nuclear (28S, RPS5) genes to test the monophyly of previously proposed subtribes of the Lithosiini (Erebidae: Arctidinae), including subtribal assignment of all North ...

Molecular insights on the conflicting generic boundaries in the Carduncellus‐Carthamus complex (Compositae)

open access: yesTAXON, Volume 71, Issue 6, Page 1268-1286, December 2022., 2022
Abstract The Carthamus‐Carduncellus complex is formed by approximately 50 taxa that are widely distributed throughout the Mediterranean basin and western Asia. The generic delineation of this complex has always been controversial. Currently, there are three widely diverging taxonomical proposals, suggesting that the complex is formed by (1) a single ...

What Is an “Arachnid”? Consensus, Consilience, and Confirmation Bias in the Phylogenetics of Chelicerata

open access: yesDiversity, 2021

Cryptic diversity within the major trypanosomiasis vector Glossina fuscipes revealed by molecular markers [PDF]

open access: yes, 2011
Background: The tsetse fly Glossina fuscipes s.l. is responsible for the transmission of approximately 90% of cases of human African trypanosomiasis (HAT) or sleeping sickness. Three G. fuscipes subspecies have been described, primarily based upon subtle

The early diversification of ray‐finned fishes (Actinopterygii): hypotheses, challenges and future prospects

open access: yesBiological Reviews, Volume 98, Issue 1, Page 284-315, February 2023., 2023
ABSTRACT Actinopterygii makes up half of living vertebrate diversity, and study of fossil members during their Palaeozoic rise to dominance has a long history of descriptive work. Although research interest into Palaeozoic actinopterygians has increased in recent years, broader patterns of diversity and diversity dynamics remain critically understudied.
