Cropping system dynamics, climate variability, and seed losses among East African smallholder farmers: a retrospective survey.

2014

Abstract Climate variability directly affects traditional low input and rain-fed farming systems, but few studies have paid attention retrospectively to the cropping system’s ability to mitigate climate risk. This study analyzes the impacts of rainfall variability on farmers’ seed variety losses over time, considering changes in smallholder farming systems. The cropping system dynamics, in favoring maize at the expense of sorghum and pearl millet, have induced an increasing risk of seed loss during drought. Combining ecological anthropology and climatology, a retrospective survey asking farmers about the period 1961–2006 was carried out at three altitudinal levels (750, 950, and 1100 m) on …

Résumé des recherches sur les bioagresseurs du riz pluvial

2009

La recherche a été menée sur plusieurs fronts ces dernières campagnes pour la lutte durable contre les bioagresseurs du riz pluvial. Elle s'est orientée vers l'exploitation de la biodiversité des plantes et la recherche de systèmes de culture pour gérer les " vers blancs " ou " scarabées noirs " (Coleoptera, Scarabaeidae), les foreurs de tiges, la pyriculariose et le striga. Les résultats des essais réalisés avec le projet BVlac sur l'utilisation du champignon entomopathogène Metarhizium anisopliae ainsi que les résultats des essais menés avec l'ONG Tafa sur la lutte contre le striga dans différents systèmes de culture seront présentés par ailleurs. Nous rapporterons ici les recherchés mené…

Harnessing the biodiversity value of Central and Eastern European farmland

2015

A large proportion of European biodiversity today depends on habitat provided by low‐intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly the central and eastern new member states have retained relatively large areas of species‐rich farmland, but despite increased investment in nature conservation here in recent years, farmland biodiversity trends appear to be worsening. Although the high biodiversity value of Central and Eastern European farmland has long been reported, the amount of research in the international literature focused on farmland biodiversity in this region remains comparatively ti…

New molecular aspects of regulation of mitochondrial activity by fenofibrate and fasting

2000

Abstract Fenofibrate and fasting are known to regulate several genes involved in lipid metabolism in a similar way. In this study measuring several mitochondrial enzyme activities, we demonstrate that, in contrast to citrate synthase and complex II, cytochrome c oxidase (COX) is a specific target of these two treatments. In mouse liver organelles, Western blot experiments indicated that mitochondrial levels of p43, a mitochondrial T3 receptor, and mitochondrial peroxisome proliferator activated receptor (mt-PPAR), previously described as a dimeric partner of p43 in the organelle, are increased by both fenofibrate and fasting. In addition, in PPARα-deficient mice, this influence was abolishe…

Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

2016

Seuls les 100 premiers auteurs dont les auteurs INRA ont été entrés dans la notice. La liste complète des auteurs et de leurs affiliations est accessible sur la publication.; International audience; In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues…

Musset : la leçon des proverbes

2015

OS nat Axe 4; National audience; L'exemple concret de trois proverbes, un en vers, Les Marrons du feu, et deux en prose Il ne faut jurer de rien et Il faut qu'une porte soit ouverte ou fermée, permet de découvrir le théâtre en liberté que Musset a pratiqué à sa façon en inventant littéralement un nouveau genre littéraire : le proverbe. La gageure poétique et dramatique que tient ici Musset est de défaire le dire pour le refaire à neuf dans sa polyphonie.

Voyage avec Musset

2019

Conférence accompagnée de lectures de nombreux textes de Musset (par Benoit Lepecq); International audience; À quoi rêvent les jeunes filles, Lorenzaccio, mais aussi Le Pélican et... Gamiani ! Venez arpenter l'espace de Musset, de Paris à Venise, en reprenant les plus belles pages de ses œuvres. Haï par Rimbaud, qui le qualifie de “quatorze fois exécrable”, Alfred, avec ses malheurs, mérite bien une séance — dans un fauteuil !

Une philosophie ‘conciliante, paisible et secrète’ ? L’article leibnitzianisme de Diderot et l’Éloge de M. Leibnitz de Fontenelle

2017

International audience; On connaît, ou on croit connaître, la dette massive de l’article leibnitzianisme ou philosophie de Leibnitz (Hist. de la Philosoph.) de 1765 à l’endroit de l’Éloge de M. Leibnitz, prononcé par Fontenelle à l’Académie royale des sciences le 13 novembre 1717, un an presque jour pour jour après la mort de celui-ci. Or l’éloge académique est un genre – genre dont Fontenelle est d’ailleurs probablement le maître – porteur d’enjeux certes philosophiques et historiques mais aussi rhétoriques et institutionnels, qui engagent la personne et la fonction du secrétaire perpétuel parisien et informent son travail de compréhension et de restitution de l’œuvre du savant mort, a for…
