Conservation status of the Hispaniolan Slider, Trachemys decorata, at Lake Trou Caïman, eastern Haiti: first data on an endemic, poorly studied, and …

2022

Hispaniolan Slider (Trachemys decorata) is a freshwater turtle of conservation interest, endemic to the island of Hispaniola. Although the species is known to be threatened with habitat destruction, hybridization with congeneric species, and commercial harvesting, little information is available on natural populations. Here we report the results of a pilot study conducted at Lake Trou Caiman, Haiti. From October 2017 to February 2018, we captured 44 individuals (mostly in areas dominated by cattails, Typhaceae) and had access to 48 additional individuals held in captivity by fishers and local people. Captive individuals were significantly larger than wildcaught ones. Based on individuals wi…

Alien flora of Europe: Species diversity, temporal trends, geographical patterns and research needs

2008

International audience; The paper provides the first estimate of the composition and structure of alien plants occurring in the wild in the European continent, based on the results of the DAISIE project (2004–2008), funded by the 6th Framework Programme of the European Union and aimed at “creating an inventory of invasive species that threaten European terrestrial, freshwater and marine environments”. The plant section of the DAISIE database is based on national checklists from 48 European countries/regions and Israel; for many of them the data were compiled during the project and for some countries DAISIE collected the first comprehensive checklists of alien species, based on primary data …

SOIL MICROBIOLOGICAL QUALITY: STATE OF THE ART AND IMPORTANCE OF MICROBIAL COMMUNITIES FOR FRENCH AGRICULTURAL SOILS

2022

Soils are one of the major reservoirs of biological diversity on our planet, hosting a huge diversity of microorganisms. Numerous studies have demonstrated the role of microbial diversity in soil functions, such as nutrient cycling or pathogen management. Given the key role of soil microorganisms in the regulation of soil ecosystem functions, the environmental factors driving soil microbial diversity need to be understood. In France, we have the opportunity to benefit from a national soil survey (called the French Soil Quality Monitoring Network), which represents one of the most extensive and without a priori soil sampling survey available to date. Through several funded projects, we were …

Du fouillis végétal à l'espace gazonné : structure et typologie des jardins réunionnais de la Ravine des Cabris

2014

International audience; S’intéresser aux jardins de l’île de la Réunion ne procède pas uniquement d’un attrait naturaliste ou esthétique car les jardins sont aussi des espaces de vie qui ont été au centre des préoccupations lors de l’épidémie de chikungunya qui a sévit sur l’île de 2005 à 2006. Les politiques de prévention ont mis l’accent sur le risque que constituait le jardin et il a été rapidement demandé à la population de devenir acteur en agissantsur son environnement et en éliminant les sources potentielles de gîtes. Dans le cadre d'un projet de recherches ANR SEST (2006-2009) « Anthropo-MTV » sur la gestion de l’épidémie de chikungunya les auteurs ont mené une enquête sur les jardi…

Landscape scale and local crop protection intensity affect the abundance of the codling moth and its predation and parasitism in apple orchards

2017

International audience; One important feature that may explain variation in pest abundance and pest biocontrol in crops is the land-use intensity in the landscapes. We report results from three studies in which we tried to address this question by assessing whether amount of semi-natural habitat and/or pesticide use at both local and landscape scales affected the abundance of codling moth, its parasitism and predation of sentinel eggs in commercial apple orchards of south-eastern France. Our results indicate that in this landscape there is indeed a significant effect of the pesticide use intensity at both the local and the landscape scales on these variables

THE FRENCH NATIONAL SOIL QUALITY MONITORING NETWORK (RMQS) AS A SUPPORT FOR MONITORING SOIL BIODIVERSITY: past, present and future programs

2021

Soil biodiversity would represent about 25% of the species on Earth. It is threatened, and although it is essential for human activities, it remains largely unknown. The French National Soil Quality Monitoring Network (RMQS) has a significant impact in removing the grey areas through its programs on soil microorganisms, soil meso and macrofauna, meadow flora, truffles and more recently enzymatic activities. The first distribution maps of bacterial phyla on a national scale and of soil fauna on a regional scale (in Brittany) have been developed. For the white truffle, three new areas of presence have been identified in France. The habitats of the bacteria were also described for the first ti…

Mapping, understanding and predicting soil microbial diversity across France

2018

International audience; Microorganisms are extremely abundant and diverse in soils. Their huge diversity is central in soil functioning regarding the diversity of functions it supports (mineralization, detoxification, stability of soil…) and is more and more studied, especially in a context of increasing pressure on soil resources. Conversely to macroorganisms whose distribution on a wide scale has been studied for over a century, spatial scaling and determinism distribution of soil microorganisms on nationwide scale still needs to be documented, notably to decipher the environmental filters shaping these communities. communities were investigated at the scale of France to characterize thei…

Programme européen en faveur de la consommation de fruits à l’école - présentation : Ce programme européen fondé sur le volontariat prévoit la distribution de fruits et légumes aux écoliers, visant ainsi à encourager les jeunes à adopter des habitudes alimentaires saines. Outre la distribution de fruits et légumes, ce programme demande aux États membres participants de mettre en place des stratégies comprenant des initiatives pédagogiques et des mesures de sensibilisation.Programme européen en faveur de la consommation de fruits à l’école - présentation :Ce programme européen fondé sur le volontariat prévoit la distribution de fruits et légumes aux écoliers, visant ainsi à encourager les je…
