Species delimitation based on diagnosis and monophyly, and its importance for advancing mammalian taxonomy

open access: yesZoological Research, 2018
A recently proposed taxonomic classification of extant ungulates sparked a series of publications that criticize the Phylogenetic Species Concept (PSC) claiming it to be a particularly poor species concept.

First record of Physyphora alceae (Preyssler, 1791) (Diptera, Ulidiidae) from a forensic case in Northern Italy: description of immature stages, DNA barcoding and phylogenetic analysis

open access: yesThe European Zoological Journal, 2021
In forensic entomology the estimation of the minimum postmortem interval and any other evaluation depend on the accuracy of the species identification. Despite the most common species received a lot of attention in the last years, other species belonging

Cowpox virus: What’s in a Name?

open access: yesViruses, 2017
Traditionally, virus taxonomy relied on phenotypic properties; however, a sequence-based virus taxonomy has become essential since the recent requirement of a species to exhibit monophyly.

Bayesian Morphological Clock Methods Resurrect Placoderm Monophyly and Reveal Rapid Early Evolution in Jawed Vertebrates.

open access: yesSystematic Biology, 2016
The phylogeny of early gnathostomes provides an important framework for understanding one of the most significant evolutionary events, the origin and diversification of jawed vertebrates.

Monophyly or Diphyly in the Origin of Whales [PDF]

open access: yesEvolution, 1968
The phyletic unity of the Cetacea is still a matter of dispute. Recently Yablokov (1964; see also Kleinenberg, 1958, 1959) has given well-reasoned arguments that much of the aquatic adaptation of the two recent suborders was evolved separately, from an ancestor without these adaptations.

Phylogeny and taxonomy of the shore-fly tribe Ephydrini with comments on related tribes in Ephydrinae (Diptera: Ephydridae) [PDF]

open access: yesZoologia (Curitiba)
Ephydrini comprises 118 species (plus seven nomina dubia species) that are distributed in all biogeographical regions except Antarctica. The tribe currently includes 13 genera, of which three (Calocoenia Mathis, Ephydra Fallén, Paracoenia Cresson ...

Flatfish monophyly refereed by the relationship of Psettodes in Carangimorphariae

open access: yesBMC Genomics, 2018
BackgroundThe monophyly of flatfishes has not been supported in many molecular phylogenetic studies. The monophyly of Pleuronectoidei, which comprises all but one family of flatfishes, is broadly supported.

Fin whale (Balaenoptera physalus) mitogenomics: A cautionary tale of defining sub-species from mitochondrial sequence monophyly

open access: yesbioRxiv, 2018
Highlights Mitochondrial monophyly is commonly employed to define evolutionary significant units. Monophyly may be caused by insufficient sampling or a recent common ancestor.

Phylogeny of some species of Astragalus (Fabaceae) based on morphological data

open access: yesیافته‌های نوین در علوم زیستی, 2020
The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program.
