Why biogeographical hypotheses need a well supported phylogenetic framework: a conceptual evaluation

open access: yesPapéis Avulsos de Zoologia, 2007
A growing number of biogeographical methods have attempted to describe formal means of reconstructing the biogeographical history of the organisms. Whatever the biogeographical method, however, the source of systematic information has to be well worked ...

The plastid and mitochondrial genomes of Vavilovia Formosa (Stev.) Fed. and the phylogeny of related legume genera

open access: yesВавиловский журнал генетики и селекции, 2020
The plastid and mitochondrial genomes of Vavilovia formosa (Stev.) Fed. were assembled on the base of the data of high-throughput sequencing of DNA isolated from a sample from North Osetia, Russia, using Illumina and PacBio platforms.

A taxonomic review of the vampire catfish genus Paracanthopoma Giltay, 1935 (Siluriformes, Trichomycteridae), with descriptions of nine new species and a revised diagnosis of the genus

open access: yesPapéis Avulsos de Zoologia, 2022
A taxonomic revision is presented of the genus Paracanthopoma, probably the least-known vandelliine genus at present. The work is based on most of the material available in museums worldwide and includes a major expansion in the knowledge about the genus.

Morphogenera, monophyly, and macroevolution [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Jablonski and Finarelli (1) suggest that morphogenera, even when they are nonmonophyletic, serve as good representatives for large-scale evolutionary studies. We feel there are two issues that warrant further discussion. First, the test used to evaluate the effect of using nonmonophyletic groups for macroevolutionary studies was not conservative and ...

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.

Review of the Afrotropical subgenus Disneyempis (Diptera: Empididae)

open access: yesEuropean Journal of Entomology, 2000
The Afrotropical subgenus Disneyempis Smith of the genus Empis L. is redescribed and redefined on the basis of three synapomorphies, namely labrum lengthened, male eyes more or less broadly separated on frons with all ommatidia of equal size, female ...

Comparing the usefulness of distance, monophyly and character-based DNA barcoding methods in species identification: a case study of neogastropoda. [PDF]

open access: yesPLoS ONE, 2011
BackgroundDNA barcoding has recently been proposed as a promising tool for the rapid species identification in a wide range of animal taxa. Two broad methods (distance and monophyly-based methods) have been used.

Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]

open access: yes, 2012
Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Multi‐gene phylogeny of North American clear‐winged moths (Lepidoptera: Sesiidae): a foundation for future evolutionary study of a speciose mimicry complex

open access: yesCladistics, Volume 39, Issue 1, Page 1-17, February 2023., 2023
Abstract Sesiids are a diverse group of predominantly diurnal moths, many of which are Batesian mimics of Hymenoptera. However, their diversity and relationships are poorly understood. A multi‐gene phylogenetic analysis of 48 North American sesiid species confirmed the traditional taxonomic tribal ranks, demonstrated the paraphyly of Carmenta and ...
