Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release
2021
Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…
Enseignement et recherche sont inséparables
2020
Les politiques publiques françaises concentrent les moyens de recherche sur quelques “sites”, aux dépens de régions entières, creusant les inégalités entre universités dites “d’élite” ou “de masse”. Mais de nombreux travaux empiriques démontrent l’inefficacité d’une telle concentration des moyens.
Physical Performance During the Menopausal Transition and the Role of Physical Activity
2020
Abstract Background To examine longitudinal changes in physical performance during the menopausal transition and the role of physical activity (PA) in these changes. Methods Based on follicle-stimulating hormone levels and bleeding diaries, women (47–55 years) were classified as early (n = 89) and late perimenopausal (n = 143) and followed prospectively until postmenopausal status, with mean duration of 17.5 and 13.8 months, respectively. Physical performance was measured by handgrip force, knee extension torque, vertical jumping height, maximal walking speed, and 6-minute walking distance. Physical activity was self-reported and categorized as inactive, low, medium, and high. Longitudinal …
Defense against predators incurs high reproductive costs for the aposematic moth Arctia plantaginis
2020
Abstract To understand how variation in warning displays evolves and is maintained, we need to understand not only how perceivers of these traits select color and toxicity but also the sources of the genetic and phenotypic variation exposed to selection by them. We studied these aspects in the wood tiger moth Arctia plantaginis, which has two locally co-occurring male color morphs in Europe: yellow and white. When threatened, both morphs produce defensive secretions from their abdomen and from thoracic glands. Abdominal fluid has shown to be more important against invertebrate predators than avian predators, and the defensive secretion of the yellow morph is more effective against ants. Her…

«Cité ou oublié» : les supports de la notoriété des professeurs en sciences de gestion vus à travers Google Scholar
2011
Standards for the evaluation of management scholars lead more and more to exclude forms of scientific production other than the articles published in international scientific journals. The aim of this paper is to test the validity of these norms by analyzing the production of all university professors in management science, based on the «influen- tial» publications in Google Scholar. The articles published in internation- al journals represent only 35 % of in- fluential publications and collect only 40.2 % of citations. Books still repre- sent a very important part and the in- fluence of the different media varies widely across sub-disciplinary fields (finance, marketing, etc.). This articl…
