Climate change is already affecting forest tree populations, as evidenced by increased forest die-off events, background mortality and the northward and upward migration of tree populations. However, forest tree populations may not be able to migrate fast enough to track the unprecedented rate of climate change. In this context, it is thus relevant...
The understanding of the molecular mechanisms that allows the rapid adaptation of mollusks that are vector of parasites, to new environments is important for disease control. Rapid adaptation is difficult to explain by traditional Mendelian genetics and there is strong evidence supporting that epigenetic mechanisms, are behind rapid adaptations in ...
L’étude de la domestication peut nous apporter des informations capitales à la fois sur notre histoire et le développement de nos sociétés, mais également sur l’évolution des espèces et les processus biologiques qui ont mené à la diversité des formes vivantes actuelles. On peut synthétiser le processus de domestication en deux étapes : la mise en r...

Orthoptera are infected by about 60 species of gregarines assigned to the genus Gregarina Dufour, 1828. Among these species, Gregarina garnhami Canning, 1956 from Schistocerca gregaria (Forsskål, 1775) was considered by Lipa et al. in 1996 to be synonymous with Gregarina acridiorum (Léger 1893), a parasite of several orthopteran species including L...
Under environmental stress, previously hidden additive genetic variation can be unmasked and exposed to selection. The amount of hidden variation is expected to be higher for life history traits, which strongly correlate to individual fitness, than for morphological traits, in which fitness effects are more ambiguous. However, no consensual pattern...
Quinoa is a crop originating in the Andes but grown more widely and with the genetic potential for significant further expansion. Due to the phenotypic plasticity of quinoa, varieties need to be assessed across years and multiple locations. To improve comparability among field trials across the globe and to facilitate collaborations, components of ...
To develop dual-purpose varieties, breeders need to improve traits linked both to grain and biomass production. To identify these traits, we studied the phenotypic plasticity of eighteen traits and the performance of ten contrasting sorghum genotypes, used in West Africa. Trials were carried out in a randomized complete blocks design with four repl...
Maritime pine is a major forest tree grown for wood production in Southern Europe. A breeding program for the selection of fast-growing varieties was established in the 1960s, in France. In the context of climate change, the magnitude of phenotypic plasticity is a key issue for the prediction of putative decreases in productivity in the improved ge...
Wild and farmed animals are key elements of natural and managed ecosystems that deliver functions such as pollination, pest control and nutrient cycling within the broader roles they play in contributing to biodiversity and to every category of ecosystem services. They are subjected to global changes with a profound impact on the natural range and ...
