Interannual memory effects for spring NDVI in semi-arid South Africa
2008
[1] Almost 20 years of Normalized Difference Vegetative Index (NDVI) and precipitation (PPT) data are analysed to better understand the interannual memory effects on vegetation dynamics observed at regional scales in Southern Africa (SA). The study focuses on a semi-arid region (25°S–31°S; 21°E–26°E) during the austral early summer (September–December). The memory effects are examined using simple statistical approaches (linear correlations and regressions) which require the definition of an early summer vegetation predictand (December NDVI minus September NDVI) and a consistent set of potential predictors (rainfall amount, number of rainy days, rainfall intensity, NDVI and Rain-Use-Efficie…
Vegetation structure and greenness in Central Africa from Modis multi-temporal data.
2013
African forests within the Congo Basin are generally mapped at regional scale as broad-leaved evergreen forests, with a main distinction between terra-firme and swamp forests types. At the same time, commercial forest inventories, as well as national maps, have highlighted a strong spatial heterogeneity of forest types. A detailed vegetation map generated using consistent methods is needed to inform decision makers about spatial forest organisation and theirs relationships with environmental drivers in the context of global change. We propose a multi-temporal remotely sensed data approach to characterize vegetation types using vegetation index annual profiles. The classifications identified…
Pre-imaginal conditioning alters adult sex pheromone response in Drosophila
2018
https://peerj.com/articles/5585/#supplemental-information; International audience; Pheromones are chemical signals that induce innate responses in individuals of the same species that may vary with physiological and developmental state. In Drosophila melanogaster, the most intensively studied pheromone is 11-cis-vaccenyl acetate (cVA), which is synthezised in the male ejaculatory bulb and is transferred to the female during copulation. Among other effects, cVA inhibits male courtship of mated females. We found that male courtship inhibition depends on the amount of cVA and this effect is reduced in male flies derived from eggs covered with low to zero levels of cVA. This effect is not obser…

Contribution de l’analyse de scène auditive à l’analyse de la performance
2017
Disponible sur : http://euromac2017.unistra.fr/wp-content/uploads/2017/05/Ext.-Lalitte-Philippe.pdf. Intervention donnée en Session 13C : Analyser la performance aujourd'hui : enjeux et perspectives; International audience; L’analyse de la performance de musiques savantes écrites des XXe–XXIe siècles pose des problèmes méthodologiques spécifiques à ce répertoire (Lalitte, 2015). Plus que dans un autre répertoire, l’interprète a un rôle particulièrement important pour transmettre à l’auditeur une image auditive (McAdams, 1984) la plus cohérente possible d’œuvres fréquemment qualifiées de perceptivement complexes. Cette constatation est particulièrement cruciale dans la musique polyphonique o…
