The implementation of regular and relevant evaluations of surveillance systems is critical in improving their effectiveness and their relevance whilst limiting their cost. The complex nature of these systems and the variable contexts in which they are implemented call for the development of flexible evaluation tools. Within this scope, participatory tools have been developed and implemented for the African swine fever (ASF) surveillance system in Corsica (France). The objectives of this pilot study were, firstly, to assess the applicability of participatory approaches within a developed environment involving various stakeholders and, secondly, to define and test methods developed to assess evaluation attributes. Two evaluation attributes were targeted: the acceptability of the surveillance system and its the non-monetary benefits. Individual semi-structured interviews and focus groups were implemented with representatives from every level of the system. Diagramming and scoring tools were used to assess the different elements that compose the definition of acceptability. A contingent valuation method, associated with proportional piling, was used to assess the non-monetary benefits, i.e., the value of sanitary information. Sixteen stakeholders were involved in the process, through 3 focus groups and 8 individual semi-structured interviews. Stakeholders were selected according to their role in the system and to their availability. Results highlighted a moderate acceptability of the system for farmers and hunters and a high acceptability for other representatives (e.g., private veterinarians, local laboratories). Out of the 5 farmers involved in assessing the non-monetary benefits, 3 were interested in sanitary information on ASF. The data collected via participatory approaches enable relevant recommendations to be made, based on the Corsican context, to improve the current surveillance system. [less ▲]

Diet composition and feeding preferences are of critical importance to understand a species' ecology; better knowledge of these matters is necessary for efficient conservation. Few is known on the trophic ecology of Mediterranean cetacean populations and the elusiveness of these organisms limits acquisition of new information. Here, we analysed C and N isotopic ratios of skin biopsies of 17 fin whales Balaenoptera physalus, 15 long-finned pilot whales Globicephala melas and 25 sperm whales Physeter macrocephalus sampled through darting between summer 2010 and 2013 in the North-Western Mediterranean Sea. We subsequently used the SIBER R package to explore isotopic niche parameters as a proxy for trophic niches assessment. Fitting of standard ellipses to each species revealed that no niche overlap between the odontocetes and fin whales was present, in accordance with the lower trophic level of the latter. Moreover, overlap between the isotopic niches of the two odontocetes was limited, confirming resource partitioning between these two species. This could be linked with differences in hunting periods and depths and consequently in prey availability. Bayesian modelling of standard ellipses revealed that the isotopic niche of fin whales was larger than the two odontocetes in over 99.80% of 106 model simulations. It is the first time that such variability is observed in Mediterranean fin whales. This suggests possible exploitation of food items from different trophic levels (krill, small fishes) or from other regions, such as other areas in the Mediterranean Sea and the North-East Atlantic. Modelling also suggested that no meaningful differences were present in the width of isotopic niches of the two odontocetes. The very narrow isotopic niche of pilot whales is in strong contrast with the generalist feeding behaviour this species is believed to have according to literature analysis. Our results open new perspectives on the ecological role of Mediterranean cetaceans. [less ▲]

The communication presents the various requirements imposed to electronic nose to become an instrument of environmental monitoring. Obstacles of the monitoring of real life environmental odours may be classified into three categories: • the final goal of the study, requiring to measure a global odour annoyance and not any gaseous emission, • the analysed sample itself, which is highly variable, due to the process evolution and to the influence of ambient parameters; • and the operating conditions, needing to work far from any building and sometimes at locations not easy to reach. The paper suggests some simple solutions to those problems. [less ▲]

Applying the electronic nose to monitor environmental odours is not straightforward. The instrument must be adapted to the final objectives. It has to pass different steps : suitable sensor selection, right choice of the target when supervised methods are used for data processing, choosing an odour-related dependant variable when using regressions, coping with the variability of environmental odour, taking the sensor drift into account, working only in concentrations above the limit of detection of the sensors, working with a mobile instrument in the field and coping with the ambient parameters.

For few years, the department "Environmental monitoring" at FUL applies the principle of the electronic nose equipped with tin oxide sensors to recognise and to monitor real life malodours in the environment and directly in the field. <br />For such emissions, the gas mixtures are very complex and only their odour should be of interest, and not their chemical composition. <br />Moreover, working in the field implies various constraints. <br />The obstacles of the monitoring of real life environmental odours with an electronic nose can be classified into three main areas : the final goal of the study (measuring an odorous annoyance), the analysed sample itself (influenced by the evolution of the process and of ambient parameters) and the operating conditions (necessity to transport the reference gas and the batteries in the field, influence of air humidity). <br />The paper describes the approach of FUL to the problem with various tests conducted in the field with home-made electronic noses based on tin oxide sensors and with very simple configurations. The conclusions, which can be extrapolated to any other sensor types, are promising, but the sensor performances (sensibility, reproducibility, electrical consumption, drift, etc.) should still be improved before reaching the final goal.

It is common practice to represent by streamfunction the transport field ensuing from the integration - over one horizontal coordinate - of the velocity field predicted by ocean models. This very useful visualization technique requires that the transport field be divergenceless. If this is not the case, it is suggested to extract the divergenceless transport field that is closest to that stemming from the model while verifying the impermeability conditions of the ocean surface and bottom. A variational approach is examined. [less ▲]

To keep up with the increase and diversity of constraints to which our forests are subjected, the forest managers need to have at their disposal a panel of information more and more complete, able to offer objective guidance in making decisions. It is within this context that the Institut Bruxellois de Gestion de l’Environnement (IBGE), an institute responsible for local environmental management, chose to equip itself with a permanent inventory of forestry samples covering amongst it the 1657 ha of the Soignes forest near Brussels. This inventory was conceived and implemented in collaboration with the Gembloux Agricultural University. It is made up of a network of observation points distributed at regular intervals throughout the forest around Brussels. No less than 400 places (circular surfaces) of a few hundred square meters each are distributed within the forest and will be subject to precise and measurable observations at regular intervals (every 4 to 8 years). These measures not only record healthy trees, but also dead trees and the biodiversity they bring, also herbaceous plants, soil conditions, topography, animal wildlife, ... Thanks to a digital database specifically devised for this inventory, the information gathered will be treated and extrapolated to offer forest wide resource data. The continuing acquisition of this detailed information together with its spatial references ensure the completeness of the inventory and will enable an analytical study of its evolution of the different parameters studied. The inventory put in place here will constitute an important source of information to those who take part in the management and more widely to the improvements of our knowledge of the forestry heritage of the region Brussels Capital.

Currently, the Ursidae family includes eight bear species. They represent an unusual family within the order of the Carnivores because of their peculiar physiological adaptations related to hibernation. These physiological features, unique in the animal kingdom, make bear a unique model for medical research in full expansion because of its putative clinical applications. This point will be developed in introduction of this manuscript. Surprisingly, the phylogenetic relationships within the extant Ursid representatives remain unclear. In order to clarify their phylogeny, we sequenced 12 nuclear genes for all the Ursid species (nearly 8 kilobases corresponding to 6 genes implied in the pathway of the thyroid hormones, 3 genes specific to the sexual chromosomes, and 3 other autosomal genes). By concatenating these new data with those available in the sequence databanks, phylogenetic reconstructions (maximum likelihood and bayesian analyses) were carried out on a nuclear DNA dataset of 10 kilobases. It was then possible to refine the phylogeny of the Ursidae family. In addition, based on the study of the genes SRY (Sex determining region of the Y chromosome), ZFX/ZFY (Zinc Finger protein) and AMLX/AMLY (Amelogenine), we developed a reliable method to determine the sex of Ursidae based on the analysis of DNA extracted from non invasive samples such as hairs or faeces. If this tool has obvious implication for the conservation biology of Ursidae (most of the extant species are threatened with extinction), it also opens new prospects in palaeontology. This kind of analysis was indeed applied to samples of fossils of North African brown bears (Ursus arctos). The last chapter of this manuscript illustrates how the palaeogenetics can help palaeontology interpreting the variability of fossil forms. [less ▲]

De nouveaux outils de mesure permettent de quantifier la cinématique et la dynamique articulaire fonctionnelle des athlètes (systèmes optoélectroniques 3D, plateforme de forces, électromyographie, …). Ces données sont importantes dans le sens où elles donnent à l’équipe médicale et sportive des informations objectives sur le geste du sportif dans sa pratique réelle. Elles favorisent la compréhension et l’amélioration de la performance ainsi que la prévention lésionnelle et la détection de situations à risque. Dans le cadre d’un suivi longitudinal des sportifs, ces mesures sont intéressantes pour mettre en place des critères objectifs et spécifiques à l’athlète de retour sur le terrain après une blessure. Ce document a pour objectif de présenter les principaux outils disponibles dans les laboratoires de biomécanique et d’illustrer leurs utilisations à travers 2 exemples : l’influence de la raideur de l’épaule sur la mobilité de l’épaule et l’analyse cinématique du service au tennis.
