Transactions 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 ...

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

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

TAXON, 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 ...

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

MonoPhy: a simple R package to find and visualize monophyly issues [PDF]
PeerJ Computer Science, 2016 Background. The monophyly of taxa is an important attribute of a phylogenetic tree. A lack of it may hint at shortcomings of either the tree or the current taxonomy, or can indicate cases of incomplete lineage sorting or horizontal gene transfer ...

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