Texto completoUsing Europe data over the 1999 to 2018, we find that analysts generally commit errors in the estimates during sunny days and sunny days are the proxies for positive mood. Further, in cloudy days, the estimates by the analysts are more accurate and cloudy days are proxies for negative mood. Moreover, the inaccuracy in analyst’s estimates changes due to additional factors like financial crisis period, star rating of the analyst and individualism which is a proxy for the cultural traits. In addition, we found that analyst’s estimates are positively biased in a sunny day which is a proxy for the happy mood and negatively biased in a cloudy day which is a proxy for the sad mood. Also, these biases change when additional factors like market cap, IBES recommendation score and uncertainty avoidance which is a proxy for cultural traits are added in the model. However, the inaccuracy and the biases do not change in case of male and female analysts. In fact, it effects at a subconscious level that is impossible for any analyst to realise. Overall, our results are consistent with the concept of cognitive stimulus conceived by mood of the analysts, who make less or more accurate estimates under the influence of positive or negative mindset due to variation in sunlight

Texto completoClimate change may affect spatial and temporal distribution of tuna species due to its impact on lower trophic levels. Hence, the aims of this thesis are (1) to determine the main environmental variables that define tuna habitat (2) to define the ranges of preference, tolerance and avoidance for these variables and (3) to study, at different scales, the effect of environment on spatiotemporal distribution of tuna and billfish of the Atlantic. Generalized additive models (GAM) were carried out to determine the environmental variables defining global tuna habitat. For each species the best model included all environmental variables considered i. E. Temperature, salinity, dissolved oxygen, sea level anomaly, mixed layer depth and chlorophyll. GAMs revealed that for most species surface temperature, dissolved oxygen and sea level anomaly were variables explaining most of CPUE deviance. Besides, the quotient analysis was used to define tuna ranges of preference, tolerance and avoidance for different environmental variables. It appeared that tropical species prefer warmer, less productive, and more oxygenated waters than temperate species. The second part of this thesis revealed that albacore and bluefin tuna seasonal movements to the Bay of Biscay appeared earlier in the 2000s than in the 1960s and 1980s, respectively. The rate of change was 2 and 5. 6 days for decade, respectively. This change was correlated with phenological changes in temperature over the same periods. Moreover, the temperature, latitude of 17 °C isotherm in particular, also showed a correlation with albacore catch latitude in adjacent waters of the Bay of Biscay. It also moved 2. 5 ° northwards over the last 40 years. Lastly, we showed that the late 1980s regime shift of the North Atlantic had an influence on the migration of these two species. Finally, a synthesis of all local studies on tuna and billfish in North and South Atlantic was addressed in a meta-analytic framework. The overall result indicates that species distribution do not correlate with temperature. However, the overall correlation was positive in the northern hemisphere. Species catch latitude showed stronger correlations with the North Atlantic Oscillation and the Southern Oscillation than with temperature. These different results suggest that temperatures could be a factor determining species local distribution whereas some ocean physical processes should be considered in order to understand tuna spatial dynamics across oceans

Texto completoRecently, sources apportionment of Volatile Organic Compounds (VOC) has been the subject of a great numbers of studies, in order to determine their contributions to atmospheric pollution. However, the dynamical behavior of atmosphere, within its micro-meteorological scale, has never been taken into account in the sources-receptor approach, yet it is the main factor to interpret near-field physic-chemical measurements of air pollution, in an urban area under industrial influences. The complexity of such a study area results from not only the emission modes and the various industrial activities, but also the meteorological phenomenon in multi-scale, which influences the dispersion and transport in a small scale (tipically several kilometers). With measurements of 85 VOC (including 23 oxygenated VOC) during several months, we have developed an innovative methodology, associating the results of the PMF (Positive Matrix Factorization) modeling and the meteorological parameters, in order to identify the sources and to understand their dynamical behaviors. By introducing the vertical turbulence for the first time in this kind of analysis, the temperature and the solar radiation, as parameters of factor analyses, two behaviors have been distinguished, leading to identify the emissions near ground and in the upper part of surface layer. In this way, we have labeled the sources according to their nature as well as their emission mode, and we have highlighted the aged air mass containing secondary pollutants

Texto completoThe concept of « ecosystem service », which has been used increasingly since the publication of the Millennium Ecosystem Assessment in 2005, has highlighted the importance of ecosystem’s non-marketed performances. In orchards, ensuring high productivity while preserving natural resources and human health has become a real challenge that could be analyzed with the concept of ecosystem service. Which ecosystem services are delivered in an apple orchard? How to analyze them? What are the relationships - conflicts or synergies – among multiple ecosystem services and how do cropping systems change multiple ecosystem service profiles? This PhD work aims at answering those questions with an innovative approach combining experimental measures, modeling and statistical analysis.Based on a literature review of ecosystem services in orchards, five services were selected: fruit production, nitrogen availability in soil, climate regulation based on the prevention of nitrogen denitrification and on carbon sequestration, maintenance and regulation of water cycle, including water quality, and pest control. We also considered the environmental disturbances caused by the use of pesticides. For each service, we identified the underlying ecosystem functions as well as the agricultural practices and soil and climate conditions affecting these functions. Services and functions were described by one or multiple indicators and quantified using models in the case of (i) nine existing cropping systems on two experimental sites in southeastern France differing in terms of soil and climate conditions, and (ii) 150 virtual cropping systems designed out of the combination of five major agricultural practice levers and their modalities, in identical soil and climate conditions. The two models used were STICS, a generic soil-crop simulation model under the influence of practices which required a parameterization and an evaluation on apple orchards based on experimental measures, and IPSIM, a generic modeling framework simulating the impacts of agricultural practices and local conditions on crop injuries caused by pests. IPSIM was parameterized on apple orchards, based on an important literature review and expert opinions. Model simulations were analyzed with simple statistics in the case of the nine existing cropping systems and with two-table multivariate analyses (principal component analysis with instrumental variables) for virtual cropping systems.Concerning the existing cropping systems, 14 important relationships were identified among ecosystem services, especially conflicts, like the one between nitrogen denitrification or leaching prevention and soil nitrogen availability on the short term, and synergies such as the one between soil humidity or carbon sequestration and nitrogen availability on the short term. These relationships are explained by the underlying ecosystem functions. Comparing service profiles among cropping systems highlighted the impacts of agricultural practices on some services. That way, on a same site, a high planting density increases fruit production and carbon sequestration. An exclusively organic fertilization decreases fruit production through nitrogen stress but also nitrogen leaching in drained water. Furthermore, service profiles are strongly influenced by the soil and climate conditions of each site. These results strengthen the need to explicitly consider the ‘agricultural practices x soil and climate conditions’ interdependence in order to analyze ecosystem services. The results obtained with the virtual cropping systems simulations confirmed those of the existing ones and gave precision on the impacts of fertilization, irrigation and pest control for codling moth, rosy apple aphid and apple scab on ecosystem functions and services

Texto completoThe objective of this work is on one hand to show the vulnerability of forest landscapes in relation to climate variability at the scale of Tanzania and on the other hand to analyze forest dynamics in order to carry out a prospective study of the dynamics of land use in the forest reserves of Pugu and Kazimzumbwi. Analysis of the TRMM data over the period from 2001 to 2013 has allowed revealing a seasonal and inter-annual variability in precipitation across the country. The inter-annual precipitation maps have made it possible to distinguish the years with low rainfall (2003, 2005, 2012 ), the years of high rainfall (2002, 2007, 2006, 2011) and the years of intermediate rainfall (2001, 2007, 2008, 2009, 2013). It has also help to distinguish 11 types of rainfall regimes marked by different patterns of seasonal variability at the scale of Tanzania. There are oppositions between the rainfall regimes of the central savannah region on one hand marked by low annual heights over an important period of seven dry months, also more affected by inter-annual variability, and the northern, southern and eastern forest regions are more humid and presenting low deficits of heights inter-annual rainfall. The sensitivity of plant phenology to rainfall variability has been analyzed by the examination of the spatio-temporal relationships between the standardized vegetation index NDVI-MODIS and rainfall (rain TRMM). The rain / NDVI correlation maps show an opposition between the dry regions of the center marked by savannah landscapes highly vulnerable to rainfall variability and the southern regions of moist forests, mountains and coastal regions, mangrove forests Reacting poorly to this rainfall variability. In the savannah regions of the center, the intensity of rain / NDI dependence is measured by a correlation coefficient of 0.70. A monitoring of the analysis of human pressures on forest reserves was carried out using the example of the Pugu and Kazimzumbwi forests during the period 1995-2015 using SPOT 6 (high resolution) and LANDSAT imagery. The land use classifications were realized from the object oriented method. The forest review shows that in 2015 (55% of which 32% is dense forest), from the two reserves only the reserve of Pugu still preserves nearly the half of its surface in forest while the reserve forest of Kazimzumbwi contains only 5% of its area. Over the entire period studied, the sub-period 2009-2014 was the most critical in terms of forest loss. In fact, within five years the forest reserves of Pugu and Kazimzumbwi have almost lost the double of their area. Based on the increased vulnerability of human pressures in the Pugu and Kazimzumbwi forest reserves and their periphery, a multicriteria analysis has made it possible to identify areas of high and low human pressures. The most vulnerable areas remain those located close to the communication axes and cities. Consequently forest reserves are more vulnerable in their eastern parts, close to major roads and major urban centers such as Pugu and Kazimzumbwi. The use of a model for prospective modeling in 2050 has required the integration of the explanatory variables of the observed changes and the land use maps of 1995 and 2014. The model is validated from a predicted map and a real map. The result shows an exact simulation at 72%, based on this hypothesis of an increase in anthropogenic human pressures on the two forest reserves over time; we have predicted the land use map of 2050 under the effect of explanatory variables. This prospective modeling therefore envisages, by 2050, an expansion and densification of artificial surfaces, notably at the north-eastern periphery of the reserve of Pugu and on the south in the kazimzumbwi reserve. This growth in artificial surfaces will result in a significant decline in existing forest areas within reserves

Texto completoBiomass burning, particularly residential wood burning, is a source of atmospheric particles that contributes significantly to winter PM10 levels globally in Europe. In order to reduce emissions from this source, a large-scale program for the renewal of non-efficient wood-burning appliances, the “Fonds Air Bois” has been launched since 2013 in the Arve Valley. The assessment of its impact on atmospheric concentrations is an issue for future air quality management policies. The research DECOMBIO program (2013-2018) has been proposed to evaluate the impact of this operation on PM10 concentrations from measurements. This DECOMBIO program, which includes these thesis works, was based on the confrontation during 4 winters of continuous measurements of PM10 resulting from biomass burning (noted PM10wb), weather conditions, and emissions variations related to appliances renewal. To answer this challenge, the aim of this thesis was to develop methods to take into account the influence of atmospheric conditions on winter PM10 concentrations and to evaluate the parameters and uncertainties that make it possible to compare the estimated PM10wb emission variations with those of the measured PM10wb concentrations during the 4 winters.This work was based on large datasets of chemical and meteorological measurements made during 4 winters (13-14 to 16-17) at 3 sites in the Arve Valley. In addition, the technical data from wood appliances renewal files was provided to us, allowing us to spatially and temporally estimated reductions of PM10wb emissions from these appliances replacements. The state of atmospheric stability, an essential parameter for determining episodes of temperature inversions, has been continuously monitored thanks to an inexpensive system of sheltered temperature sensors installed along the slopes. These measurements have shown that local weather conditions in these valleys are the primary factor conditioning atmospheric concentrations. An automatic weather types classification has been established, making it possible to overcome this variability and to compare the concentrations for similar atmospheric conditions between the different winters. The innovation of this approach is mainly based on taking into account the degree of influence of meteorological variables and parameters related to the intensity of emissions. A gradual decrease of PM10wb concentrations during winters was thus observed at the 3 sites for certain weather types, a result consolidated by the concomitant decrease in tracer biomass combustion at the mass of PM10. To clarify these results, we were interested in estimating the reduction of PM10 emissions from device replacements at measurement sites and their uncertainties.At the end of this work and of the DECOMBIO program, we have been able to develop and validate several methodological tools applicable in the evaluation of future “fonds air bois” (use of sensors along the slopes, meteorological classification adapted to the quality of the air, estimation of uncertainties on wood appliances renewable emissions). This solid foundation has allowed us to better understand the measurements made on atmospheric PM, and their relationship to emission estimates
