Ecologie moléculaire d'une relation hôte - parasite en contexte insulaire marin. Crabes parasites des oursins spatangues en Mer des Caraïbes
2014
Comparing the population genetic structures of two species documents on the environmental factors and life history traits that shape the dispersal of the individuals. For host-parasite couple, this approach also permits to predict local adaptation of these species. The investigated species in this work are the ectoparasitic crab Dissodactylus primitivus and its sea urchin host Meoma ventricosa, both species being endemic to the Caribbean and neighboring American coasts. Several molecular markers were used, namely microsatellites and cytochrome oxidase I (mitochondrial). Moreover, morphometric analyses (shape) were also done. By studying populations across the Antilles arc and along the Pana…

Cartes et élections : la construction des circonscriptions électorales aux Etats-Unis, entre égalité et équité
2003
Maps and Elections : The Construction of Electoral Districts in the USA. Decennal census-led redistricting in the United States is the occasion for court actions focused nowadays on the political representation of ethnic minorities. Computer tools make possible the building of districts specifically tailored for Blacks or Hispanics, but blatant racial gerrymandering is now rejected by the US Supreme Court. This paper examines the most relevant judicial decisions and describes several local cases.

Diversity and phylogeography of Southern Ocean sea stars (Asteroidea)
2019
How is life distributed on the Southern Ocean sea floor? How can we explain species distribution patterns, their origin and the underpinning drivers? These questions are central to macroecological studies, especially in regions facing fast environmental changes. The main objective of this thesis was to describe and characterise distribution patterns of sea stars species (Echinodermata: Asteroidea) with regards to reproductive strategy (i.e. brooding versus broadcasting), a key life history trait for species dispersal. I tested whether contrasting dispersal abilities between direct developers (brooders) and species with pelagic larvae in their development (broadcasters) result in distinct di…

Les déterminants des compétences sociales des élèves de cycle III
2016
Les différences de réussite à l’école primaire traditionnellement étudiées par les chercheurs en éducation peuvent être analysées à la lumière des compétences et plus particulièrement des compétences sociales. Champ théorique encore en construction, les compétences sociales deviennent tout de même un « incontournable » pour les acteurs du système éducatif et pour la recherche en sciences de l’éducation. Par une approche pluridisciplinaire, cet article propose d’étudier quels sont les déterminants des compétences sociales à l’aide d’indicateurs sociodémographiques et scolaires largement empruntés dans les modèles d’explication des différences de réussite, auxquels sont associées des mesures …
Empirical tests of the multicentric urban models
1999
Since the seventies the effects of city size growth and diversification of economic activities on the multipolarisation of economic activities have questioned the theoretical and empirical appropriateness of the monocentric urban pattern to explain and describe the spatial organization of the modern metropolitan areas. New assumptions were based on multicentric and nonmonocentric urban economics models, which have become the core of new economic geography analysis during the nineties. At the same time, a lot of empirical studies have attempted to describe the urban economic patterns of North American metropolitan areas. Using this empirical literature, the aim of this paper is to propose a …
Towards the observation of Territorial Energy Systems : a geographical design approach for energy territorialisation
2014
Having an effect on a system calls for a thorough knowledge of it. The main goal of this research is toprovide a general framework for the interpretation of geographic information, as well as a methodologicalframework to understand the interrelations between territory and energy in the context of a territorialobservatory. A literature review of energy planning on the one hand and spatial planning on the other revealssimilar developments in the two fields, in particular in terms of decentralisation and environmental concerns.The change of geographical scale chosen for the analysis brings new possibilities for public intervention. Inthis context, therefore, local authorities have a key role t…
