Phylogenetic relationships of selected European Ennominae (Lepidoptera: Geometridae)

open access: yesEuropean Journal of Entomology, 2011
This study reports the results of a molecular phylogenetic analysis of thirty three species of Ennominae (Lepidoptera: Geometridae). The aim of this analysis was to determine the phylogenetic affinities of 13 European species not previously studied using

On the origin of Halipeurus heraldicus on Round Island petrels: cophylogenetic relationships between petrels and their chewing lice [PDF]

open access: yes, 2010
Lice phylogenetic relationships have often been used to elucidate host relationships and vice versa. In this study, we investigate the louse genus Halipeurus which parasitizes bird hosts in the families Procellariidae, Hydrobatidae and Pelecanoididae ...

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Phylogenetic relationships of the genus Sibynophis (Serpentes: Colubroidea)

open access: yesPapéis Avulsos de Zoologia, 2012
We present the results of the first molecular analysis of the phylogenetic affinities of the Asian colubroid genus Sibynophis. We recovered a sister-group relationship between Sibynophis and the New World Scaphiodontophis.

Student News [PDF]

open access: yes, 2018
Calyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved.

Extremotolerant fungi from alpine rock lichens and their phylogenetic relationships

open access: yesFungal diversity, 2015
Fungi other than the lichen mycobiont frequently co-occur within lichen thalli and on the same rock in harsh environments. In these situations dark-pigmented mycelial structures are commonly observed on lichen thalli, where they persist under the same ...

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Phylogenetic relationships in the family Alloherpesviridae [PDF]

open access: yesDiseases of Aquatic Organisms, 2009
Phylogenetic relationships among herpesviruses (HVs) of mammals, birds, and reptiles have been studied extensively, whereas those among other HVs are relatively unexplored. We have reconstructed the phylogenetic relationships among 13 fish and amphibian HVs using maximum likelihood and Bayesian analyses of amino acid sequences predicted from parts of ...
