An assessment of Allis shad larvae and juvenile tolerance to oxythermic stress
Projections of grapevine phenophases under future climate change scenarios are strategic decision support tools for viticulturists and wine producers. Several phenological models are tested for budburst, flowering, and veraison and for two main grapevine varieties (cv. Touriga Franca and Touriga Nacional) growing in the Douro Demarcated Region. Fou...
Fragmentation acting over geological times confers wide, biogeographical scale, genetic diversity patterns to species, through demographic and natural selection processes. To test the effects of historical fragmentation on the genetic diversity and differentiation of a major European forest tree and to resolve its demographic history, we describe a...
Les sols agricoles représentent près de 66 % des émissions anthropiques de protoxyde d’azote (N2O), 3ème gaz responsable de l’effet de serre additionnel. La variabilité des émissions mesurées au champ est élevée. La structure du sol impacte à la fois la production et le transport du N2O dans le profil de sol. L’objectif de cette thèse était de comp...
Les jardins communs forestiers doivent être suivis, conservés, maintenus, voire étendus avec de nouvelles essences et doivent être bien renseignés et répertoriés dans les plans d’aménagements.Les résultats qui en sont issus doivent être diffusés et portés à la connaissance de tous, comme se proposent de le faire les projets en cours soutenus par le...
Geodetic tools monitor the earth’s deformation and gravity field. They are presently sensitive enough to record subtle changes triggered by hydrological processes, thus providing complementary data to standard hydrological measurements. Among these tools, superconducting gravimeter (SG) have proven useful to unravel groundwater redistribution, whic...
Thermal infrared remote sensing observations have been widely used to provide useful information on surface energy and water stress for estimating evapotranspiration (ET). However, the revisit time of current high spatial resolution (
Background: Grain yield of wheat is greatly associated with the population of wheat spikes, i.e., spike number m(-2). To obtain this index in a reliable and efficient way, it is necessary to count wheat spikes accurately and automatically. Currently computer vision technologies have shown great potential to automate this task effectively in a low-e...
