Повний текст джерелаAs the compromise between agriculture and biodiversity is mainly based on land management, and hence space, it is crucial to better understand at which spatial scales this compromise has to be developed. In this thesis, we aim to identify characteristic scales of biodiversity for different groups and levels of biological organization and we study the scale effects that may occur in agriculture-environment-biodiversity relationships. We present four studies, three of which relate to pond ecosystems, and we emphasize the highly valuable functions of these ecosystems in agricultural landscapes. In the first part, we study the effects of analysis scales and of influence scales in amphibian-environment relationships. We show the relevance of combining network-centred strategies of conservation with more localized actions. In the second part, we examine the effects of policy scales in the response of bird biodiversity to crop practices and landscape. These drivers have contrasted influences according to the scales and the species ecological traits. In the third part, we identify characteristic scales of aquatic macroinvertebrates community and we explore hypotheses about the potential processes underlying these patterns. Overall, this thesis highlights the necessity and the chance of compromises for maintaining biodiversity in agricultural landscapes. In particular, we advocate that such compromises can efficiently be designed and achieved only by explicitly accounting for scale effects in the relationships between agriculture, environment and biodiversity

Повний текст джерелаThe quality control of aquatic ecosystems requires tools for continuous and in situ detection as biosensors. This work proposes the development of biosensors for detection of some pollutants families. These tools are based on the measurement of two enzymatic activities in saline and freshwater algal cells. The first step was to find enzymatic activities varying with the presence of pollutants, this was studied in bioassays. Thus, we have shown that Alkaline Phosphatase Activity (APA) is sensitive to heavy metals and phosphates and that the Esterase Activity (AE) is sensitive to some pesticides. These results enabled us to develop different biosensors. For the detection of heavy metals, two conductometric biosensors have been developed. The first, based on the measurement of the APA of freshwater microalgae Chlorella vulgaris (Cv) immobilized by self assembled monolayers, lead to an improvement the repeatability and reproducibility measures as compared to previous works. The second biosensor, based on the same measurement, resulted in the overcoming of the effects of phosphate on Cv APA. For phosphate detection, a conductometric whole algal cells biosensor was developed with a detection limit of 0. 4µM phosphate ions. Finally, for pesticides detection in the marine environment, a conductometric biosensor based on measurement of AE in two marine algae has been developed. The results showed that it is sensitive to the presence of diuron and glyphosate. The biosensors developed in this study, will require same additional testing on natural samples, and then they could be used by managers for decision making

Повний текст джерелаAlthough the persistence of the H5N1 virus in the environment is possible, there is no well-defined and standardized method for the detection of viruses from water, soil or mud. In addition, there is very little data available regarding the role of H5N1 virus in the environment in the tropics. In this work methods of concentration, identification, and quantification of influenza viruses in water, mud and soils have been developed, validated and used to test environmental samples collected following H5N1 outbreaks in Cambodia and to analyze samples obtained during experiments in artificial aquatic biotopes aiming to reproduce as faithfully as possible the characteristics observed in ponds and lakes in Cambodia. The H5N1 viral RNA was detected in 19% of environmental samples. Among these, infectious viral particles were isolated in a single water sample. In experimental systems, the infectious H5N1 virus survived only 4 days in the rain water. But viral RNA persisted up to 20 days in rain water and 7 days in pond and lake water. In mud, infectious viral particles did not survive even viral RNA could persist for at least 2 weeks. Aquatic flora and fauna have no influence on infectious H5N1 virus persistence in water. These organisms seem to concentrate and to passively carry the virus but do not allow virus replication. Our results showed that following outbreaks, the environment is widely contaminated by H5N1 virus and therefore can act as a potential source of human and/or animal contamination. Restricted access to potentially contaminated water should be recommended during outbreak episodes. Monitoring the environment is recommended in the effort to fight against avian influenza and measures including environment disinfection should also be considered

Повний текст джерелаAquatic ecosystems are fragile systems, vital for the biosphere and yet subject to numerous, sometimes significant, anthropogenic pressures. Currently, reliable methods allow the quantification and study of the fate of metallic trace elements (Pb, Zn, Cd, etc.) and many organic micropollutants in water and sediments. For other elements such as rare earths or platinum group elements, which are increasingly used by industry, their quantification remains more complex and even uncertain due to their very low concentrations. Their quantification is practically impossible without the use of preconcentration techniques or the development of specific analytical methods to reduce the spectral interferences linked to interferents present in high concentrations in the environment. This research work has allowed (i) to quantify precisely these elements by inductively coupled plasma mass spectrometry combined with the use of a collision/reaction cell by judiciously choosing the gas and its flow applied in the cell ; (ii) to preconcentrate in situ and then determine concentrations ranging from pg L-1 to ng L-1 for platinum group elements, in areas impacted by human activities (road leaching, Pt-based drug releases), by developing passive sampling techniques called "Diffusive Gradients in thin films (DGTs)" based on the use of two different resins, and (iii) to better understand how some of these elements can be used as tracers of urban discharges, particularly in connection with wastewater treatment plants containing domestic and hospital discharges, in addition to the tracers usually used. To this end, the Marque River served as a pilot site for this prospective study during a period of low water levels. These studies made it possible to determine the current concentrations of rare earths and platinum in environments heavily impacted by human activities, making it possible to monitor their evolution and evaluate their potential impact in the future

Повний текст джерелаPharmaceuticals and their residues belong to the so-called “emerging” pollutants for which no current regulation is applied regarding their presence in the environment. Monitoring the contamination of aquatic resources by these kinds of micropollutants is a necessity in order to anticipate potential effects regarding human health and ecosystems. In this context, data quality (traceability and comparability) is compulsory so as to take better decisions regarding policies to be driven. Psychotropic compounds, which are widely consumed, display a great concern in that field.This thesis aimed at characterizing occurrence of psychotropic compounds in the environment and putting forward metrological tools insuring accuracy, traceability, comparability as well as representativity of the measurement results.To that purpose, a SPE-LC-MS² multi-residue method has been developed for a selection of psychotropic compounds and other commonly consumed drugs. Method limits of quantification were in the range of ng.L-1 which enabled to characterize their occurrence in several surface waters and treated wastewaters. Concurrently, usage of integrative samplers was evaluated and applied on the field in different locations. Occurrence levels of 68 selected compounds were established by implementation of this complementary strategy in aquatic systems. Furthermore, results from measurement campaigns were used to rank studied compounds into a short list of interest. Finally, a reference method using isotopic dilution and mass spectrometry (DI-MS) was developed for the characterization of 24 psychotropic compounds in surface waters. Expanded uncertainties (k=2) inferior to 10% were obtained. Last be not least, implementing this method to environmental analysis emphasized the importance of sampling related uncertainties regarding to global measurement uncertainties

Повний текст джерелаThe conservation of water quality is a major issue in the 21th century in particular with the increase in the human population. Water-treatment plants rejections represent a risk of pollution of the receiving environment, in particular in nitrogen and phosphorus, with fatal effects for the health and the environment. It is to limit this pollution that the vegetated buffer zones (VBZs), systems of infiltration, where water and nutrients retention are expected, were developed. This study has for main objective to better understand the transfers of nutrients in this type of system. The impact of the various compartments - soil, vegetation, microflora- was studied in two VBZs ditches type, situated downstream to vegetated water-treatment plants in service and in an experimental zone with controlled modalities. This study demonstrated the importance of site hydraulic, soil texture and VBZ surface in effectiveness of water and nutrients retention. The impact of microbial compartment depends largely on the hydraulic retention time bonds to VBZ surface and oxygenation rate of the effluent. Vegetation allows microbial activity improvement but its role in nutrients retention and removal is minor because of high quantities brought by effluents. The soil is the major compartment in phosphorus retention, although a rapid saturation of soil phosphorus could limit this potential. These observations demonstrate variability in the effectiveness of VBZ in water and nutrients retention. This variability could be minimized by planning and management measures. The study of nutrients transfers deserve to be further study and extended to all types of VBZ

Повний текст джерелаAquatic environments and their surroundings in arid and semi-arid regions are subjected to strong anthropogenic pressure resulting from agriculture and industrial activities. These unique areas are characterized by natural salinity and drastic seasonal fluctuations. The thesis provides information to better understand the factors shaping the microbial communities assemblages and their adaptation to pollutants under extreme environmental conditions, in order to examine the possibility to define microbial bioindicators. Such microbial bioindicators constitute promising tools for a careful environmental monitoring, which is required to evaluate the ecological status and environmental health of ecosystems in arid and semi-arid regions. In order to decipher the rules governing the assemblages of microbial communities inhabiting soils and sediments in arid and semi-arid zones, we investigated microbial communities around the Ichkeul Lake (Tunisia) and the “Saladas de Bujaraloz-Sástago” (Salineta, Monegros, Spain), two emblematic aquatic RAMSAR ecosystems. Metagenomic approaches, chemical analyses and integrative microbial indexes were combined to determine the relationships between microbial composition and environmental parameters. We identified the impacts of pollutants such as hydrocarbons, pesticides and heavy metals on microbial communities in soils and sediments and characterized microbial community dynamics according to seasonal variations. We defined relevant microbial bioindicators adapted, identified microbial specialists adapted to the environmental conditions, particularly to natural salinity. Finally, this study provides new insight for developing biomonitoring tools, requested for the management and restoration of aquatic ecosystems
