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.

APE: Analyses of Phylogenetics and Evolution in R language

open access: yesBioinform., 2004
UNLABELLED Analysis of Phylogenetics and Evolution (APE) is a package written in the R language for use in molecular evolution and phylogenetics. APE provides both utility functions for reading and writing data and manipulating phylogenetic trees, as ...

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.

Relaxed Phylogenetics and Dating with Confidence

open access: yesPLoS Biology, 2006
In phylogenetics, the unrooted model of phylogeny and the strict molecular clock model are two extremes of a continuum. Despite their dominance in phylogenetic inference, it is evident that both are biologically unrealistic and that the real evolutionary

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.

Model selection and model averaging in phylogenetics: advantages of akaike information criterion and bayesian approaches over likelihood ratio tests.

open access: yesSystematic Biology, 2004
Model selection is a topic of special relevance in molecular phylogenetics that affects many, if not all, stages of phylogenetic inference. Here we discuss some fundamental concepts and techniques of model selection in the context of phylogenetics.

Scalable Bayesian phylogenetics

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2022
Recent advances in Bayesian phylogenetics offer substantial computational savings to accommodate increased genomic sampling that challenges traditional inference methods. In this review, we begin with a brief summary of the Bayesian phylogenetic framework, and then conceptualize a variety of methods to improve posterior approximations via Markov chain ...

Phylotranscriptomic insights into a Mesoproterozoic–Neoproterozoic origin and early radiation of green seaweeds (Ulvophyceae)

open access: yesNature Communications, 2022
“Ulvophyceae is a remarkably morphologically and ecologically diverse clade of green algae. Here, the authors reconstruct the Ulvophyceae phylogeny, showing that these algae originated earlier than expected and may have influenced biogeochemical cycles ...
