The evolutionary history of the Arabidopsis arenosa complex : diverse tetraploids mask the Western Carpathian center of species and genetic diversity [PDF]

open access: yes, 2012
The Arabidopsis arenosa complex is closely related to the model plant Arabidopsis thaliana. Species and subspecies in the complex are mainly biennial, predominantly outcrossing, herbaceous, and with a distribution range covering most parts of latitudes ...

Revision of European Brachysira species (Brachysiraceae, Bacillariophyta): III. Species formerly included in the Brachysira serians-complex

open access: yes, 2021
This third paper revising the European Brachysira species deals with Brachysira serians and the closely related B. brebissonii–intermedia complex. The morphology of these species is characterised in greater detail than before based on a combination of ...

The herring gull complex is not a ring species [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Under what circumstances speciation in sexually reproducing animals can occur without geographical disjunction is still controversial. According to the ring-species model, a reproductive barrier may arise through 'isolation by distance' when peripheral populations of a species meet after expanding around some uninhabitable barrier.

Xiphinema krugi, Species Complex or Complex of Cryptic Species?

open access: yesJournal of nematology, 2012
Fourteen morphologically putative populations of X. krugi were clearly separated into four different profiles by RFLP analysis (Alu I and Hinf I), sequencing of the ITS-1 region, and subsequent Maximum Likelihood phylogenetic analyses. These four profiles were further supported by a principal component analysis of morphometric characters that yielded ...

Zoophilic and anthropophilic behaviour in the Anopheles gambiae complex [PDF]

open access: yes
The work included in this thesis arose from a long-standing interest in the possible use of genetic control for one of the most important malaria vectors in Africa, Anopheles gambiae sensu stricto.

Gibberella musae (Fusarium musae) sp. nov., a recently discovered species from banana is sister to F. verticillioides [PDF]

open access: yes, 2011
Several strains of Fusarium isolated from banana were identified previously as F. verticillioides (Sacc.) Nirenberg but described as unable to produce fumonisin.

Expanding Soil Invertebrate Knowledge in Panama: The Genus Lepidocyrtus (Collembola, Entomobryidae) in the Parque Natural Metropolitano as a Study Case

open access: yesInsects
Panama, located in the heart of the Mesoamerican hotspot, harbors an extraordinary species diversity across the Tree of Life. The Collembola species of the genus Lepidocyrtus play an important role in soil biological processes such as decomposition ...

From the Clinical Mycology Laboratory: New Species and Changes in Fungal Taxonomy and Nomenclature

open access: yesJournal of Fungi, 2018
Fungal taxonomy is the branch of mycology by which we classify and group fungi based on similarities or differences. Historically, this was done by morphologic characteristics and other phenotypic traits.

Phylogeny and taxonomy of the Ophiostoma piceae complex and the Dutch elm disease fungi [PDF]

open access: yes, 2001
The Ophiostoma piceae complex forms a monophyletic group of insect-dispersed pyrenomycetes with synnemata (Pesotum) and micronematous (Sporothrix) synanamorphs. Other species of Ophios-toma outside of the O.

Susceptibility testing in Aspergillus species complex [PDF]

open access: yesClinical Microbiology and Infection, 2014
Methods for susceptibility testing of Aspergillus are developed and validated by the European Committee on Antibiotic Susceptibility Testing Subcommittee on Antifungal Susceptibility Testing. Breakpoints for phenotypic antimicrobial susceptibility testing have been determined by breakpoint committees and as part of regulatory processes for the approval
