The management of crop-livestock systems at a territory level: the example of grain legume crops and of monogastric livestock in Burgundy, France
2012
Although cereals and oil seed crops are very developed in Burgundy, the area of grain legumes cultivation is small. Concerning monogastric livestock, the region is characterised by a medium size poultry production focussed on markets under quality and origin signs (SIQO) and a relatively small pig production. Although a tendency of co-location of these productions can be observed (at territory and farm scales) and some animals consume locally-produced proteins, there is no strong functional link between these crops and animal activities. This situation is confirmed by the fact that a significant proportion of produced grain legumes are exported by Burgundy, while large quantities of soybean…

Background: Ectomycorrhizal (ECM) fungi develop a mutualistic symbiotic interaction with the roots of their host plants. During this process, they undergo a series of developmental transitions from the running hyphae in the rhizosphere to the coenocytic hyphae forming finger-like structures within the root apoplastic space. These transitions, which involve profound, symbiosis-associated metabolic changes, also entail a substantial transcriptome reprogramming with coordinated waves of differentially expressed genes. To date, little is known about the key transcriptional regulators driving these changes, and the aim of the present study was to delineate and functionally characterize the trans…

International audience; La preuve de la filiation maternelle, résumée par l’un des adages les plus connus en droit de la famille, Mater semper certa est, a pendant longtemps semblé être une évidence voulue par la nature, donc ne posant que peu de problème juridique, à l’inverse de la paternité. Pourtant, l’évidence a-t-elle toujours été aussi flagrante ? Pourquoi ressentir le besoin de forger un adage ? Quelle fut sa valeur et a-t-il toujours parfaitement reflété la réalité ? Force est de constater que si la maternité est certaine, la preuve de celle-ci se heurte à plusieurs difficultés tant matérielles que processuelles. Il s’agit donc ici de s’interroger sur la place accordée en droit à l…

Biological invasions are recognized as a significant evolutionary factor over short time scales. In particular, their effect is well recorded on the genetic structure of populations, the patterns of phenotypic evolution and the richness of parasite fauna associated to invasive populations. This study aims at quantifying the consequences of a biological invasion according to these three levels (genetical, phenotypical and parasitological) taking as example the Mozambique tilapia Oreochromis mossambicus. This African cichlid is characterized by an unusual conservation status since it is both (i) ranked among the world's worst invasive species due to its global dispersion during the 20th centu…
