Parmi les stratégies d'adaptation des villes aux changements climatiques et notamment aux événements de chaleur extrême, la réintroduction de la végétation en ville est une solution intéressante. La végétation, par sa transpiration et son ombrage, a en effet un impact significatif sur le bilan énergétique de l'atmosphère urbaine. Un programme de re...
Fish are sensitive to temperature, but the intergenerational consequences of maternal exposure to high temperature on offspring adaptive behaviour and underlying mechanisms are unknown. Here we show that a thermal maternal stress induces emotional and cognitive disorders in offspring. Thermal stress in mothers triggered the inhibition of fear respo...
The objective of this work is to bring new information about the influence of temperatures (7 C and 20 C) on the equation of state and sol–gel transition behavior of casein micelle dispersions. Casein micelle dispersions have been concentrated and equilibrated at di erent osmotic pressures using equilibrium dialysis at 7 C and 20 C. The osmotic str...
The singular property of shrinkage is used in the packaging sector to wrap products. Polyethylene film products are mostly produced by either blown or cast film extrusion. During processing, under the effect of drawing, the molten polymer is stretched in one or two dimensions according to the cast or blown film extrusion. When the resulting solid f...
Les modèles de cultures sont des outils très utilisé pour prédire le rendement des cultures dans des climats fictifs. Ils permettent d’anticiper les effets du changement climatique et d’autres contraintes et de prévoir des solutions pour améliorer notre agriculture. Mais les modèles actuels n’ont qu’une prise en compte limitée de l’impact de l’hist...

Although plant functional trait combinations reflect ecological trade-offs at the species level, little is known about how this translates to whole communities. Here, the authors show that global trait composition is captured by two main dimensions that are only weakly related to macro-environmental drivers.
Agroforestry practices may be a sound strategy towards agroecological and climate-resilient strategies for grape and wine production but have almost never been referenced. The thesis work participated in the project Vitiforest and focused on the positive interactions/competitions between grapevine and trees through the local impacts of trees on the...
The fungus Ampelomyces quisqualis is a parasite of the powdery mildew Oidium neolycopersici. In this study, we have demonstrated that its protective effect on tomato may not require the maintenance of high level of relative humidity. This result was observed for two levels of temperature: 21°C and 28°C. It contrasts with published literature on the...
