Article
The Garâa Sejenane is an ancient lake in northern Tunisia that currently houses a mosaic of temporary wetlands. Comparison of modern pollen data and field vegetation surveys shows both a weak regional pollen signal and the homogenization of pollen assemblages at the scale of the garâa. Despite a hiatus between 19,000 and 2230 cal. BP, fossil pollen...

This study addresses the conservation issues of the hydrophytic vegetation of Garâa Sejenane, the largest natural freshwater wetland in Tunisia. Fifty-five phytosociological relevés reveal the exceptional floristic wealth, including 74 hydrophytes of which 26 are patrimonial species. Multivariate analyses (CA, AHC) differentiate three types of habi...
Article
Les objectifs de ce travail sont d'échantillonner la végétation de champs de céréales adjacents de prairies pâturées pour estimer la composition botanique et la richesse spécifique dans les lisières entre ces deux éco-systèmes. Cinq sites d'études ont été choisis dans le Parc naturel régional du Luberon car ils étaient inclus dans des mesures agri-...
Article
Since the beginning of the 20th century, the concepts of ecotones, ecoclines and edge effects have been discussed from a theoretical point of view. However, there have been very few experimental tests of these ideas, which are sometimes radically different. This study presents data from field experimental researches and determines the status of tra...
Article
Very few studies have been carried out on the ecological restoration of arable weed communities because farmers consider these species as competitors with the cultivated species. However, such restoration projects are interesting to be undertaken in south-eastern France (Parc Naturel Régional du Luberon) because there are still enough of the arable...
Article
Après leur dissémination,les graines peuvent rester viables dans le sol de quelques mois à plusieurs centaines d’années.Ce stock constitue une véritable mémoire séminale de la communauté végétale qui peut être utilisée pour sa restauration quand la végétation de surface a évolué vers d’autres formations végétales. Dans le territoire du Parc naturel...
Article
Dans le territoire du Parc naturel régional du Luberon, p e rsistent de nombreuses exploitations en polyculture-élevage comprenant des troupeaux d'ovins qui pâturent les chaumes après la moisson (estoubles) où directement des céréales de printemps (céréales à pâturer). Des premières observations ayant montré la fo rte richesse de ces champs en espè...

Article
La protection des messicoles (plantes inféodées aux champs de céréales) fait l’objet d’un paradoxe. Alors que les conservateurs d’espaces (Parc naturel régional du Luberon) et d’espèces (Conservatoire botanique national de Porquerolles) les protègent pour leur forte valeur patrimoniale ; les exploitants agricoles, quant à eux, les considèrent comme...
Article
Mineral contents of cereal stubble: the case of an agricultural exploitation in southeastern France (Vaucluse). In south-eastern France, where extensive farming systems still exists, including itinerant livestock keeping, cereal stubbles are used at the end of the grazing season. Nevertheless, little information on the mineral values of this forage...

In south-eastern France, where extensive farming systems still exists, including itinerant livestock keeping, cereal stubbles are used at the end of the grazing season. Nevertheless, little information on the mineral values of this forage is available. For the same grazing system of an agricultural exploitation of the Luberon regional natural park...
Article
Competitive abilities of plants were interpreted by measuring their morphological traits in interspecific competitive cultivation conditions. Measurements were realised by a comparative approach with interspecific cultivation of fourteen arable weeds growing with a domestic species cultivated at a large scale: the winter wheat (Triticum aestivum va...

Article
De nombreuses recherches ont été menées sur la dynamique des mauvaises herbes des grandes cultures car elles entrent en compétition avec les plantes culti-vées pour l'eau, les éléments minéraux, l'espace et la lumière. Les arguments développés pour la protection des espèces adventices des grandes cultures sont essen-tiellement basés sur leur forte...
Article
Studies on the distribution of arable weed species relative to the field boundary have already been performed, although most of these studies have been realised in north-western Europe on intensively managed arable fields. Nevertheless, it is important to examine arable weed communities in more extensive cropping systems to increase our knowledge o...
