First record of the peacock fly Callopistromyia annulipes (Diptera: Ulidiidae) in Romania [PDF]

open access: yesTravaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, 2020
The peacock fly Callopistromyia annulipes (Macquart, 1855) is recorded for the first time in Romania, from several locations. Its current distribution in Europe and some data regarding the ecology of the species are presented.

PANTHER: Making genome‐scale phylogenetics accessible to all

open access: yesProtein Science, 2021
Phylogenetics is a powerful tool for analyzing protein sequences, by inferring their evolutionary relationships to other proteins. However, phylogenetics analyses can be challenging: they are computationally expensive and must be performed carefully in ...

Omicron variant genome evolution and phylogenetics

open access: yesJournal of Medical Virology, 2021
Following the discovery of the SARS‐CoV‐2 Omicron variant (B.1.1.529), the global COVID‐19 outbreak has resurfaced after appearing to be relentlessly spreading over the past 2 years.

Phylogenetic Comparative Methods on Phylogenetic Networks with Reticulations [PDF]

open access: yesSystematic Biology, 2017
Abstract The goal of phylogenetic comparative methods (PCMs) is to study the distribution of quantitative traits among related species. The observed traits are often seen as the result of a Brownian Motion (BM) along the branches of a phylogenetic tree. Reticulation events such as hybridization, gene flow or horizontal gene transfer, can

Maximum likelihood pandemic-scale phylogenetics

open access: yesbioRxiv, 2022
Phylogenetics has a crucial role in genomic epidemiology. Enabled by unparalleled volumes of genome sequence data generated to study and help contain the COVID-19 pandemic, phylogenetic analyses of SARS-CoV-2 genomes have shed light on the virus’s ...

The first record of Trichocera (Saltrichocera) annulata (Diptera: Trichoceridae) in Romania, with additional data on Trichocera (Saltrichocera) maculipennis [PDF]

open access: yesTravaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, 2020
The Romanian Trichoceridae fauna is poorly known. Trichocera (Saltrichocera) annulata Meigen, 1818 and Trichocera (Saltrichocera) maculipennis Meigen, 1818 are amongst the most widespread species in Europe, but the former species was not recorded from ...

Diverse Host Spectrum and the Parasitic Process in the Pantropical Hemiparasite Cassytha filiformis L. (Lauraceae) in China

open access: yesDiversity, 2023
Many hemiparasites attach to a range of different host species, resulting in complex parasite–host interactions. Comprehensive molecular phylogenies allow the investigation of evolutionary relationships between these host plants. We surveyed the hosts of

Galactic Phylogenetics [PDF]

open access: yesProceedings of the International Astronomical Union, 2017
AbstractPhylogenetics is a widely used concept in evolutionary biology. It is the reconstruction of evolutionary history by building trees that represent branching patterns and sequences. These trees represent shared history, and it is our contention that this approach can be employed in the analysis of Galactic history.

Tangent Phylogenetic PCA [PDF]

open access: yes, 2023
Phylogenetic PCA (p-PCA) is a version of PCA for observations that are leaf nodes of a phylogenetic tree. P-PCA accounts for the fact that such observations are not independent, due to shared evolutionary history. The method works on Euclidean data, but in evolutionary biology there is a need for applying it to data on manifolds, particularly shapes ...
