Third-codon transversion rate-based _Nymphaea_ basal angiosperm phylogeny -- concordance with developmental evidence [PDF]

open access: yes, 2007
Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years.

New Molecular Approach for the Detection of Kinetoplastida Parasites of Medical and Veterinary Interest

open access: yesMicroorganisms, 2020
Kinetoplastids are protozoa containing a range of ubiquitous free_living species−pathogens of invertebrates, vertebrates and even some plants. Some of them are causative agents of canine vector-borne diseases.

Testing use of mitochondrial COI sequences for the identification and phylogenetic analysis of New Zealand caddisflies (Trichoptera) [PDF]

open access: yes, 2009
We tested the hypothesis that cytochrome c oxidase subunit 1 (COI) sequences would successfully discriminate recognised species of New Zealand caddisflies. We further examined whether phylogenetic analyses, based on the COI locus, could recover currently

Unique perfect phylogeny is NP-hard [PDF]

open access: yes, 2010
We answer, in the affirmative, the following question proposed by Mike Steel as a $100 challenge: "Is the following problem NP-hard? Given a ternary phylogenetic X-tree T and a collection Q of quartet subtrees on X, is T the only tree that displays Q ?

The mitochondrial genome of Lamellomphalus manusensis Zhang & Zhang, 2017 (Gastropoda: Neomphalida) from deep-sea hydrothermal vent

open access: yesMitochondrial DNA. Part B. Resources, 2022
We report the nearly complete mitochondrial genome sequence of Lamellomphalus manusensis Zhang and Zhang , a deep-sea snail inhabiting hydrothermal vent. The mitogenome is 15,990 bp in length, has a base composition of A (35.7%), T (33.5%), C (15.4%) and

A probabilistic model for gene content evolution with duplication, loss, and horizontal transfer

open access: yes, 2005
We introduce a Markov model for the evolution of a gene family along a phylogeny. The model includes parameters for the rates of horizontal gene transfer, gene duplication, and gene loss, in addition to branch lengths in the phylogeny. The likelihood for

Taxonomy and phylogeny of the Old World jumping plant-louse genus Paurocephala (Insecta, Hemiptera, Psylloidea) [PDF]

open access: yes, 2002
Fifty-one species are recognized in the genus Paurocephala, with an additional 14 species which remain unnamed. Thirty-five species are described as new, and five species are synonymized: P. pumilae and P. zhejiangensis with P.
