AMPK an energy sensor involved in male fertility control – FERTiNERGY
In birds and mammals (including humans), nutrition and energy metabolism strongly influence reproduction. In agronomy and more particularly in poultry, the intense selection of chickens for meat production promotes rapid muscle development and leads to have a negative energy balance that affects fer
Distribution and consequences of heritable viruses in host-parasitoid communities – viromics
Most insects are hosts to bacterial symbiont. These symbiont may deeply affect the phenotype of the insects in various ways. Nowadays, we begin to have a satisfactorily view of their diversity, their phenotypic effects (ranging from parasitism to mutualism), and circulation in insect communities. In
The effects of climate change on parasites: toward an integrative and predictive approach – INCLIMPAR
A common wisdom holds that parasites will spread extensively, and will expand their geographic range northward as climate will go warmer. Although expansion range of parasites might greatly affect wildlife, predictions concerning animals and plants parasites are mostly conceptual. Moreover, the asso
Communal nutrition in ants – NUTRIANTS
The proposed work on nutrition and social organization in ants addresses a question that has long been recognized, but rarely studied: how are the collective nutritional needs of a colony regulated through the actions of their individual members? The main strength of the proposal is the rigorous stu
Evolutionary dynamics and genetic basis of dominance : sporophytic self-incompatibility in the Brassicaceae as a case study. – BRASSIDOM
Dominance, the genetic phenomenon whereby one of the two alleles at a diploid locus is masked at the phenotypic level, is one of the earliest observations of classical genetics, yet also one whose genetic basis and evolution remain poorly understood. Dominance modifiers, i.e. genetic elements contro
Estimation of Maternal effects On the sustainability of large pelagic populaTIONs – EMOTION
There is now a general recognition of the fishing overcapacity in all world oceans and of the necessity to reducing exploitation rates to rebuild marine resources. While fisheries science has focused in the last decades on developing more realistic population dynamics models, the collection of data
Evolutionary consequences of Natural Enemies in Major biological Invasions : the role of parasites in the invasion success of two commensal rodents – ENEMI
ENEMI project aims at deciphering the role of parasitism and of associated immunological changes in the success of two major biological invasions currently ongoing in Senegal. These invasions involve rodent species acting as potential reservoirs of several human diseases, the black rat Rattus rattus
Microbial communities associated with the marine degradation of wood – MICADO
Considerable amounts of wood and plant material can be exported punctually by flooding rivers under the Mediterranean climate, contributing significantly to the transport of organic matter across the continental-marine interface. The export of that terrigenous organic material will rise globally in
Are emerging Infectious Disease determinant of socially structured Population evolution? The case of Ebola-Gorilla system. – IDiPop
To understand the impact of infectious diseases on the viability of threatened populations, the project focuses on the analysis of populations of Western lowland gorillas in Congo that experienced Ebola outbreaks and were monitored before and after the epizooties. The project focuses on two main obj
Functional relationships between Cyanobacteria and Bacteria: dynamic of the phycosphere and internal N recycling – PHYCOCYANO
The main goal of this project is a functional analysis of the bacterial communities associated with N2- fixing and non N2-fixing Cyanobacteria in lake. We are studying: (1) the genetic diversity and the metabolic activities of the bacterial communities, during a diel cycle with a metatranscriptomic
Epigenetic Natural varIation in Arabidopsis – ENIgmA
Nous cherchons à mieux caractériser cette nouvelle forme de variabilité pour pouvoir dans un second temps l’exploiter à des fins d’amélioration variétale. L’objectif est de pouvoir déterminer dans quelle mesure les épiallèles peuvent être transmis à la descendance sur plusieurs générations et donc s
GLOBAL AND REGIONAL ENVIRONMENTAL CHANGES AND EFFECTS ON CORAL REEF BIODIVERSITY AND RESILIENCE – LIVE AND LET DIE
We aim to test the effects of regional and global environmental change on larval recruitment. We will focus on the most pervasive threats on coral reefs: the effects of sedimentation rate increases, ocean acidification and COTS. Finally, we will measure the effects of a regional environmental change
Evo-devo of the diversification and loss of dentition in Birds – PIAFS
Today none of the 11,000 species of birds has teeth, and none of the fossil birds known since the beginning of the Cenozoic (66 million years ago: K-Pg extinction crisis) either. However, most species of birds had teeth earlier, at the time of dinosaurs, the Mesozoic, as well as almost all vertebrat
Characterisation of the mineralosphere bacterial communities and genes involved in the mineral weathering process in forest soils. – BACTOWEATHER
Unlike farmland, forests growing on acidic soils are among the terrestrial ecosystems that are least influenced or amended by man. Forests developed on acidic soils are characterized by an important stock of inorganic nutrients entrapped in poorly weatherable soil minerals. Aside from the contributi
