[more ▼] In a rapidly changing world, human activities offer opportunities for many plant species to colonize new areas. Increasingly, it is recognized that colonization can be accompanied by different ecological and evolutionary processes, acting over relatively short periods of time. When populations colonize novel environments, individuals’ phenotypes will depend on a combination of different, non-exclusive processes, including phenotypic plasticity (PP), local adaptation (LA), environmental maternal effects (EME) and genetic drift (GD)(Monty and Mahy 2009b). Despite these processes have long been studied independently, few attempts have been made to simultaneously address the importance of those processes in plant colonization. Here, we present a set of related studies aiming at disentangling the role of PP, LA, EME and GD in Senecio inaequidens (Asteraceae) in southern France, where it was introduced at a single wool-processing site in the late 19th century. We used seeds from populations growing in contrasted climates to explore the phenotypic variation related to climate. We performed several common garden experiments (Monty et al. 2009, Monty and Mahy 2009a, 2010), as well as a reciprocal sowing experiment with gardens under Mediterranean and Pyrenean climates (Monty et al. in revision). We analyzed climatic phenotypic variation in germination, growth, reproduction, leaf physiology and survival. We characterized genetic structure in the studied populations using AFLP. We found consistent genetic differentiation in growth traits but no home-site advantage, thus weak support for LA to climatic conditions. In contrast, genetic differentiation showed a relationship to colonization history. PP in response to climate was observed for most traits, and it played a particularly important role in leaf trait variation. EME mediated by seed mass influenced all but leaf traits under harsh climate. Heavier, earlier-germinating seeds produced larger individuals that eventually produced more flower heads throughout the growing season. However in a milder climate, EME were negligible. Our different studies suggest that phenotypic variation in response to climate depends on various ecological and evolutionary processes associated with geographical zone and life history traits. Therefore, we argue that a “local adaptation vs. phenotypic plasticity” approach, as often considered in the literature, is not sufficient to fully understand what shapes phenotypic variation and genetic architecture of colonizing populations.

[more ▼] Tous les spécialistes du domaine de l’économie régionale s’accordent à reconnaître l’importance des villes sur le développement économique, l’innovation et la création d’emplois. Etonnement, l’importance des villes n’était pourtant pas soulignée explicitement par la liste de questions soumise au printemps 2012 au collège d’experts de la démarche Wallonie 2022. Depuis lors, elle est toutefois régulièrement réapparue, en particulier lors des réunions du groupe de travail chargé de la ligne de force relative à la mobilisation du territoire. Dans cette perspective, il est opportun de mieux cerner comment les dynamiques urbaines sont susceptibles de s’inscrire dans la stratégie « Horizon 2022 », ce que vise précisément cette note structurée en quatre chapitres. Le premier de ces quatre chapitres est dédié au rôle moteur des villes sur le développement économique. Nous y passons en revue les thématiques des économies d’agglomération, de la métropolisation et du rôle de la qualité des centres urbains sur l’attractivité des territoires. Le second chapitre est ensuite consacré aux sujets de l’étalement urbain et de la dégradation des espaces urbains traditionnels. Sans conteste, ces évolutions lourdes sont bien plus problématiques en Wallonie qu’au sein des régions voisines, ce qui ne manque pas d’entraîner de nombreux problèmes qui risquent de devenir de plus en plus difficilement gérables. Au troisième chapitre, nous focalisons notre réflexion sur le sujet de la politique de la ville. Nous y présentons en particulier les dispositifs imaginés en Flandre afin de répondre aux grands enjeux que pose le monde urbain. Au quatrième et dernier chapitre, nous nous appuyons sur les éléments rassemblés dans les trois premières parties du document afin de mettre en avant des pistes de réflexions et de propositions qui pourraient permettre à la dynamique « Horizon 2022 » de prendre le meilleur parti du potentiel urbain de la Wallonie. Ces pistes visent à rencontrer les trois objectifs suivants : mieux intégrer la donne métropolitaine dans l’aménagement stratégique du territoire wallon, développer une politique des villes digne de ce nom et mieux limiter l’étalement urbain.

[more ▼] A subproblem method for solving eddy current finite element is developed to correct the inaccuracies near edges and corners arising from thin shell models. Such models replace thin volume regions by surfaces but neglect border effects in the vicinity of their edges and corners. A thin shell solution, performed by a simplified mesh near the thin structures, serves as a source of a correction problem consisting of the actual volume thin regions alone and concentrating the meshing effort on the thin regions. The general case of multiply connected thin regions is considered.

[more ▼] This paper deals with time-domain homogenisation of multi-turn windings and laminated cores in 2D and 3D finite- element (FE) modelling of rotating electrical machines. Herein the number of additional degrees of freedom (auxiliary field variables) in the homogenised regions can be fixed depending on the extent of the eddy current effects and on the desired accuracy. The homogenisation technique is illustrated and validated by means of a 2D model of a switched reluctance motor. Global quantities, such as the phase impedance, converge very well to those produced by a precise but very expensive 3D model.

[more ▼] Diabrotica virgifera virgifera Le Conte is considered one of the most important pests of corn grown in monoculture. Damage caused by the Western Corn Rootworm is considerable. The attack is produced by larvae and adults, serious affecting the grain production. Following laboratory analyzes may notice a decrease in the values of all track quality indicators for ears harvested from plants attacked by Diabrotica virgifera virgifera compared with the cobs from the healthy plants. Values of fat content of attacked cobs ranged from 2.76 and 4.23%, protein content ranged from 9.1 to 10.6% and starch between 69.7 and 70.5%. The average fat content of the cobs attacked percentage decreased by 11%, protein content by 16% and starch content dropped by less than one percent. [less ▲] Detailed reference viewed: 31 (3 ULg) |
