Genomic Diversity and Recombination among Xylella fastidiosa Subspecies

open access: yesApplied and Environmental Microbiology, 2019
Xylella fastidiosa is an important vector-borne plant pathogen. We used a set of 72 genomes that constitutes the largest assembled data set for this bacterial species so far to investigate genetic relationships and the impact of recombination on ...

Revisiting the Andean butterfly Eryphanis zolvizora group (Lepidoptera, Nymphalidae) : one or several species? [PDF]

open access: yes, 2014
Eryphanis zolvizora (Hewitson, 1877) is a rare Andean endemic butterfly, described from Bolivia, which has been historically classified either as a unique species, or as part of a group of three allopatric species from Bolivia, Ecuador and Colombia.

Three subspecies of Pelargonium laevigatum (Geraniaceae)

open access: yesBothalia: African Biodiversity & Conservation, 1995
Pelargonium laevigatum (L. f.) Willd. is a variable species. The macromorphology, anatomy of the leaves, chromosome numbers and geographical distribution of the species were studied, and it is concluded that three subspecies should be distinguished.

Distinct Proteomic Signatures in 16 HDL (High-Density Lipoprotein) Subspecies

open access: yesArteriosclerosis, Thrombosis and Vascular Biology, 2018
Objective— HDL (high-density lipoprotein) in plasma is a heterogeneous group of lipoproteins typically containing apo AI as the principal protein. Most HDLs contain additional proteins from a palate of nearly 100 HDL-associated polypeptides.

Phylogenetic and phenotypic divergence of an insular radiation of birds [PDF]

open access: yes, 2010
Evolutionary divergence of lineages is one of the key mechanisms underpinning large scale patterns in biogeography and biodiversity. Island systems have been highly influential in shaping theories of evolutionary diversification and here I use the ...

Identifying Morphs of the Yellow-Legged Hornet (Vespa velutina) and Other Pests of Quarantine Importance with Geometric Morphometrics

open access: yesDiversity
We assess the accuracy of geometric morphometrics (GMM) for determining the origin of insects of quarantine importance using the Asian hornet (Vespa velutina Lep.1836) as a case study.

Subspecies in the global human gut microbiome

open access: yesMolecular Systems Biology, 2017
Population genomics of prokaryotes has been studied in depth in only a small number of primarily pathogenic bacteria, as genome sequences of isolates of diverse origin are lacking for most species.

Novel Tetraplex Quantitative PCR Assays for Simultaneous Detection and Identification of Xylella fastidiosa Subspecies in Plant Tissues

open access: yesFrontiers in Plant Science, 2019
Xylella fastidiosa (Xf) is an insect-borne bacterium confined to the xylem vessels of plants. This plant pathogen has a broad host range estimated to 560 plant species.

Phylogeography of Dolichophis Populations in the Aegean Region (Squamata: Colubridae) with Taxonomic Remarks

open access: yesDiversity
In this study, we investigate the phylogeographic patterns of Dolichophis species in the Aegean region, aiming to elucidate their genetic diversity and putative historical colonisation routes through mitochondrial and nuclear DNA data.
