The origin of herbicide-resistant Chenopodium album: analysis of genetic variation and population structure Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Chenopodium album is a predominantly self-fertilising weed species common in temperate regions of the world that has developed resistance to photosystem II inhibitors. The genetic variation and population structure of eight populations from North West Europe were investigated using 416 amplified fragment length polymorphism (AFLP) markers. The populations were checked for their level of herbicide resistance by pot experiments and the ...
Population structure and genetic diversity of Rhipicephalus microplus in Zimbabwe Instituut voor Tropische Geneeskunde Universiteit Gent
Recently there was an expansion in the geographic range of Rhipicephalus microplus in Zimbabwe. In order to understand gene flow patterns and population structure in this highly invasive and adaptable cattle tick, a population genetics study was carried out. Eighty-seven R. microplus tick samples drawn from 5 distinct populations were genotyped using eight polymorphic microsatellite loci. Genetic diversity (HQ) was high (0.755-0.802) in all ...

Electrocardiographic left ventricular hypertrophy in relation to peripheral and central blood pressure indices in a Nigerian population Universiteit Hasselt KU Leuven
Purpose: Previous studies that addressed whether left ventricular hypertrophy is more closely associated with central than peripheral blood pressure (BP) have been inconsistent. Radial artery wave generated by applanation tonometry and calibrated with brachial BP in 162 adult Nigerians were analysed by using generalized transfer function to derive central BP. Materials and methods: We compared the associations of ECG voltages and left ...
Population genomic structure of the gelatinous zooplankton species Mnemiopsis leidyi in its non-indigenous range in the North Sea. Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Nonindigenous species pose a major threat for coastal and estuarine ecosystems. Risk management requires genetic information to establish appropriate management units and infer introduction and dispersal routes. We investigated one of the most successful marine invaders, the ctenophore Mnemiopsis leidyi, and used genotyping by sequencing (GBS) to explore the spatial population structure in its nonindigenous range in the North Sea. We analyzed ...
Unexpected recovery and non-effects predicted with a mixture toxicity implementation in a population model Universiteit Gent
Current regulations in risk assessment are very substance-based and only regard effects observed in lab-standardized tests on individual organisms. However, in the environment organisms are exposed to mixtures of chemicals that vary in concentration and composition. In addition, effects on individuals will have an effect on populations and higher levels of organisation in the ecosystem. Mechanistic, individual-based models have been proposed to ...
Spatial distribution and general population characteristics of mysid shrimps in the Westerschelde estuary (SW Netherlands) Vlaams Instituut voor de Zee Universiteit Gent
The distribution and general population characteristics of five mysid shrimps were investigated in theperiod 20032005 in the Westerschelde estuary, a tidal temperate estuary situated along the DutchBelgian border. Multivariate analyses revealed that salinity predominantly governs the spatial distribution of Neomysis integer, Gastrosaccus spinifer, Schistomysis kervillei and Schistomysis spiritus while temperature, and to a lesser extent ...
Association of left ventricular structure and function with peripheral blood mitochondrial DNA content in a general population Universiteit Hasselt KU Leuven
Background/objectives: mtDNA content might be an important biomarker in heart disease prediction and to date no population studies are available on the association of mtDNA content with cardiac structure and function. We, therefore, investigated in a general population in cross-sectional and longitudinal studies whether echocardiographic indexes of LV structure and function are associated with mtDNA content measured in peripheral blood cells. ...
