Changes in agricultural practices and forest fragmentation can have a dramatic effect on landscape connectivity and the dispersal of animals, potentially reducing gene flow within populations. In this study, we assessed the influence of woodland connectivity on gene flow in a traditionally forest-dwelling species--the European roe deer--in a fragmented(More)
Dispersal is a fundamental process in ecology because it influences the dynamics, genetic structure and persistence of populations. Furthermore, understanding the evolutionary causes of dispersal pattern, particularly when they differ between genders, is still a major question in evolutionary ecology. Using a panel of 10 microsatellite loci, we investigated(More)
The "ovarioleukodystrophies" comprise a group of rare leukodystrophies associated with primary or premature ovarian failure. Some of the patients have a variant of "vanishing white matter disease" with mutations in subunits of eukaryotic initiation factor 2B (EIF2B). A 32-year-old woman who developed neurological signs related to an extensive(More)
Beef cow-calf farming systems are assumed to be resilient to biological disturbances that induce variations in herd demography; however, this hypothesis has not been fully investigated to date. Modeling is an interesting approach to study farming system resilience and to evaluate the impact of biological disturbances, taking into account interactions(More)
As previous studies of genetic polymorphism in the mouflon (Ovis gmelini) have not provided any valuable markers for population studies, we tested the capacity of microsatellites to index the genetic diversity of a recently introduced mouflon population. Six pairs of bovine primer amplified microsatellites in mouflon, and all six were polymorphic.(More)
The purpose of this article is to determine how the heterogeneity of the different regulatory frameworks governing genetic laboratories in Australia, France, the United Kingdom, and the United States hinder the international availability of genetic tests. We conclude that a better understanding of the various national standards governing genetic(More)
High aspect ratio, rod-like and single crystal phase GaAs nanowires (NWs) were grown by gold catalyst-assisted hydride vapor phase epitaxy (HVPE). High resolution transmission electron microscopy and micro-Raman spectroscopy revealed polytypism-free zinc blende (ZB) NWs over lengths of several tens of micrometers for a mean diameter of 50 nm.(More)
Officially approved in May 2005, the SPIRAL2 project is under construction at GANIL, with the active participation of French laboratories (CEA, CNRS) and international partners. This new facility is composed of a linear accelerator producing deuteron, proton and heavy ion beams in a wide range of energies and intensities, with two dedicated experimental(More)
Solid state NMR measurements using 13C, 1H and 19F nuclei (MAS, CP-MAS) underline the surface chemistry of nanodiamonds from different synthesis (detonation, high pressure high temperature and shock compression). The comparison of the spin-lattice relaxation times T1 and physicochemical characterization (spin densities of dangling bonds, specific surface(More)
