Invasion biology and agriculture are intimately related for several reasons and in particular because many agricultural pest species are recent invaders. In this paper we suggest that the reconstruction of invasion routes with population genetics-based methods can address fundamental questions in ecology and practical aspects of the management of biological invasions in agricultural settings. W...
When starting a new collaborative endeavor, it pays to establish upfront how strongly your partners commit to the common goal and what compensation can be expected in case the collaboration is violated. Diverse examples in biological and social contexts have demonstrated the pervasiveness of making prior agreements on posterior compensations, suggesting that this behavior could have been shaped...
introduction and aims: until today human stomach is the only recognized habitat of h. pylori . however, recruitment of dna-based methods has made possible the detection of h. pylori in water and oral cavity, thus suggesting faecal-oral and oral-oral routes for transmission of h. pylori , respectively. in this study yeast has been proposed as a common vector for transmission of h. pylori . thus ...
Magnetic and magnetofluorescent nanoparticles have become important materials for biological applications especially for sensing, separation, and imaging. To achieve target specificity, these nanomaterials are often covalently modified with binding proteins such as antibodies or proteins. Here we report on the creation of nanoparticle libraries that achieve specificity through multivalent modif...
Biological invasions are generally thought to occur after human aided migration to a new range. However, human activities prior to migration may also play a role. We studied here the evolutionary genetics of introduced populations of the invasive ant Wasmannia auropunctata at a worldwide scale. Using microsatellite markers, we reconstructed the main routes of introduction of the species. We fou...
Proteins fold into three-dimensional structures in a funneled energy landscape. This landscape is also used for functional activity. Frustration in this landscape can arise from the competing evolutionary pressures of biological function and reliable folding. Thus, the ensemble of partially folded states can populate multiple routes on this journey to the native state. Although protein folding ...
In this paper we propose a model of visually guided route navigation in ants that captures the known properties of real behaviour whilst retaining mechanistic simplicity and thus biological plausibility. For an ant, the coupling of movement and viewing direction means that a familiar view specifies a familiar direction of movement. Since the views experienced along a habitual route will be more...
The production of effective drugs has continuously been a challenging process for researchers due to the occurrence resistive diseases. Drugs derived from natural product-based compounds as an active scaffold have gained interest in drug development wide range biological properties. Benzoheterodiazepines, product derivative bicyclic chalcones widely reported with various therapeutic potentials....
