Complex population genetic structure of the bark beetle predator Thanasimus formicarius (L.) (Coleoptera: Cleridae) across its European range

Agricultural and Forest Entomology, EarlyView.
Abstract Thanasimus formicarius (L.) (Coleoptera: Cleridae) is an important bark beetle predator and can reduce bark beetle population densities of some of the most severe forest pests in Europe. We analysed the population genetics and phylogeography of T.

Detection and Characterization of the Fimbrial sfp Cluster in Enterohemorrhagic Escherichia coli O165:H25/NM Isolates from Humans and Cattle [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT The sfp cluster, encoding Sfp fimbriae and located in the large plasmid of sorbitol-fermenting (SF) enterohemorrhagic Escherichia coli (EHEC) O157 (pSFO157), has been considered a unique characteristic of this organism.

Note on a NAHE Variation

, 2011
We present a variation of the NAHE-basis for free fermionic heterotic string models. By rotating some of the boundary conditions of the NAHE periodic/anti-periodic fermions {y^m, \bar{y}^m, w^m, \bar{w}^m,}, for m = 1 to 6, associated with the six ...

Low genetic variation and strong genetic structure across a range of geographical scales in European smelt (Osmerus eperlanus L.)

Journal of Fish Biology, EarlyView.
Abstract Populations of anadromous European smelt (Osmerus eperlanus L.) are declining across its range with mitigation efforts for this ecologically important species hindered by a lack of demographic information. Here, mitochondrial DNA (mtDNA) and microsatellite analyses were used to describe historical and recurrent demographics for the species ...

Rapid Microarray-Based Genotyping of Enterohemorrhagic Escherichia coli Serotype O156:H25/H−/Hnt Isolates from Cattle and Clonal Relationship Analysis [PDF]

Applied and Environmental Microbiology, 2010
ABSTRACT Since enterohemorrhagic Escherichia coli (EHEC) isolates of serogroup O156 have been obtained from human diarrhea patients and asymptomatic carriers, we studied cattle as a potential reservoir for these bacteria. E.

Exploring Ant‐Mollusk Interactions: Insights From Southern Spain

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study reports new data about ant‐mollusk interactions from accidental field observations, a quantitative analysis of the snail shells found in 16 Messor ant nest cleanings, and a qualitative analysis of 51 additional nests of different species. ABSTRACT Ants occupy a great variety of habitats, perform essential ecological roles, and interact with ...

Unraveling the Genetic Diversity and Phylogeography of the “King of Vitamin C” Fruit (Rosa roxburghii Trattinnick) in Chinese Southwest

Ecology and Evolution, Volume 15, Issue 5, May 2025.
The study revealed high genetic diversity within R. roxburghii populations, with Guizhou Province identified as the center of origin and distribution. At least two glacial refugia were present during the Quaternary ice age. The potential distribution model suggests that the suitable habitat for R.

Outbreak of haemolytic uraemic syndrome in Norway caused by stx 2-positive Escherichia coliO103:H25 traced to cured mutton sausages [PDF]

BMC Infectious Diseases, 2008
Abstract Background On 20–21 February 2006, six cases of diarrhoea-associated haemolytic uraemic syndrome (HUS) were reported by paediatricians to the Norwegian Institute of Public Health. We initiated an investigation to identify the etiologic agent and determine the source of the outbreak in order to implement ...
