Water-use efficiency and transpiration across European forests during the Anthropocene
2015
Considering the combined effects of CO2 fertilization and climate change drivers on plant physiology leads to a modest increase in simulated European forest transpiration in spite of the effects of CO2-induced stomatal closure. The Earth’s carbon and hydrologic cycles are intimately coupled by gas exchange through plant stomata1,2,3. However, uncertainties in the magnitude4,5,6 and consequences7,8 of the physiological responses9,10 of plants to elevated CO2 in natural environments hinders modelling of terrestrial water cycling and carbon storage11. Here we use annually resolved long-term δ13C tree-ring measurements across a European forest network to reconstruct the physiologically driven r…
Urban Heat Island and air quality, Dijon, winter 2014-2015.
2016
For the 2014-2015 Winter, thetemperature patterns and the Air Quality measured over the Grand Dijon urban area are studied together.Meteorological conditions favoring the development of an Urban Heat Island (UHI) are distinguished fromthose giving rise to pollution episodes. Winter UHI are next characterized, with radiative situations followedafter the sunset by relatively strong UHI (about 3°C), and days with no insolation during which anthropogenicheat is suspected to produce a small UHI (few tenths of °C).
Discriminating impacts of geomorphological and human factors on vineyard soil erosion (Burgundy, France)
2014
International audience; The Burgundy vineyards have been recognized for the high diversity of Terroirs, controlled by complex interactions between natural features, historical parameters and soil management practices. Vineyards are known to undergo substantial soil loss in comparison with other types of agricultural land. Hydric erosion on vineyards is controlled by complex interactions of natural and anthropogenic factors leading to intra-plot spatial heterogeneities of topsoil at a scale of a metre. Studying the relationship between soils and their degradation is crucial in this situation where soil sustainability is threatened. This study explores the relative influences of historical an…

Predictors of Left Ventricular Hypertrophy in Hypertensive Patients with Normal ECG
2011
Introduction: Early identification of left ventricular hypertrophy (LVH) in hypertensive patients is of great importance for correct stratification of cardiovascular (CV) risk. It is well known that ECGhas low sensibility in detecting LVH, while echocardiography, for organizational difficulties, cannot be performed routinely. Aim: To evaluate the prevalence of LVH and of anomalies of diastolic function in a group of hypertensive patients free of diabetes, CV diseases, and with normal ECG. Methods: We excluded patients with CV diseases, diabetes, chronic kidney disease (CKD), or having ECG-LVH or other ECG anomalies. Then, we enrolled 310 hypertensive patients (mean age 48 years). All enroll…
L’immunità parlamentare nel contesto europeo (CGUE, Grande Sezione, sentenza 6 settembre 2011, C-163/10, Patriciello)
2012
Le immunità parlamentari rappresentano uno dei temi caldi del panorama giuridico contemporaneo, rispetto al quale si confonde il confine tra politica e diritto. Le guarentigie riconosciute ai membri delle Camere, nate in un’epoca in cui il potere Legislativo doveva essere protetto da interferenze altrui, hanno vissuto un periodo di abusi e vengono oggi continuamente messe in discussione. Le ripercussioni di questo vissuto sono profondamente sentite anche in ambito europeo, dove si susseguono interventi giurisprudenziali in materia. Con la sentenza che di seguito verrà esaminata, la Corte di Giustizia dell’Unione ha aggiunto un nuovo tassello al mosaico del sistema delle immunità degli europ…
The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…
2004
One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…
Inversions de température dans le Jura
2018
L'étude des inversions, événements climatiques qui provoquent de nombreux pics de pollution nocifs, est primordiale. Quatorze sites composés de deux stations proches et quatre autres mettant en relation une station de plaine avec une station de montagne permettent d'analyser la fréquence, l'intensité et la durée des inversions locales et régionales. La fréquence moyenne des inversions est élevée lors des tn (50 %) avec des maximums supérieurs à 70% en certains sites et en décembre. L'intensité des inversions tant locales que régionales est faible (respectivement 2°C et 1°C en moyenne). La durée des inversions est faible : 60 % d'entre elles concernent juste la fin de nuit. Parmi les inversi…
