Miocene diversification of a golden‐thread nanmu tree species (Phoebe zhennan, Lauraceae) around the Sichuan Basin shaped by the East Asian monsoon

open access: yesEcology and Evolution, 2020
Understanding the role of climate changes and geography as drivers of population divergence and speciation is a long‐standing goal of evolutionary biology and can inform conservation. In this study, we used restriction site‐associated DNA sequencing (RAD‐

The complete plastid genome of Selaginella erythropus (Selaginellaceae), a species with distinctive giant chloroplasts

open access: yesMitochondrial DNA. Part B. Resources, 2021
The plastid genome of the deep-shade plant Selaginella erythropus, which has highly unusual chloroplasts, was characterized using Illumina pair-end sequencing.

PhyloSuite: An integrated and scalable desktop platform for streamlined molecular sequence data management and evolutionary phylogenetics studies

open access: yesMolecular Ecology Resources, 2019
Multigene and genomic data sets have become commonplace in the field of phylogenetics, but many existing tools are not designed for such data sets, which often makes the analysis time‐consuming and tedious. Here, we present PhyloSuite, a (cross‐platform,

Robust information from phylogenetic trees? [PDF]

open access: yes, 2010
Traditional information criteria approaches can lead to misleading model choice in comparative phylogenetics. I present both these weaknesses and a more robust comparison by likelihood ratio.

Phylogenetic diversity and biodiversity indices on phylogenetic networks [PDF]

open access: yesMathematical Biosciences, 2018
In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their contribution to overall phylogenetic diversity.

Evolution of proteins and proteomes: a phylogenetics approach

open access: yesEvolutionary Bioinformatics, 2005
The study of evolutionary relationships among protein sequences was one of the first applications of bioinformatics. Since then, and accompanying the wealth of biological data produced by genome sequencing and other high-throughput techniques, the use of

First record of Hesperomyces virescens (Laboulbeniales, Ascomycota) on Harmonia axyridis (Coccinellidae, Coleoptera) in Poland

open access: yesActa Mycologica, 2016
Hesperomyces virescens Thaxt. is a fungal parasite of coccinellid beetles. One of its hosts is the invasive harlequin ladybird Harmonia axyridis (Pallas). We present the first records of this combination from Poland.

Conservation Significance of the Rare and Endangered Tree Species, Trigonobalanus doichangensis (Fagaceae)

open access: yesDiversity, 2022
Trigonobalanus doichangensis is a rare and endangered species with important evolutionary value and extremely small populations. We investigated the genetic diversity of T. doichangensis to provide information on its effective preservation.

Molecular phylogenetics of Melastomataceae and Memecylaceae [PDF]

open access: yes, 2001
Melastomataceae are among the most abundant and diversified groups of plants throughout the tropics, but their intrafamily relationships and morphological evolution are poorly understood. Here we report the results of parsimony and maximum likelihood (ML)

Laserocarpum, a new genus of Apiaceae endemic to Greece

open access: yesActa Societatis Botanicorum Poloniae, 2019
Laserpitium pseudomeum is an endemic umbellifer of Greece occurring in the mountains of Sterea Ellas and northern Peloponnese. Molecular data indicate that it is not related to its putative congeners, but instead constitutes an isolated lineage.
