Increasing the use of synthetic fertilisers and pesticides in agroecosystems has led to higher crop yields, accompanied by a decline in biodiversity at the levels of field, cropping system and farm. Biodiversity decline has been favoured by changes at landscape level such as regional farm specialisation, increases in field size, and the removal of ...
The present study describes the assimilation of river water level observations and the resulting improvement in flood forecasting. The Kalman Filter algorithm was built on top of a one-dimensional hydraulic model which describes the Saint-Venant equations. The assimilation algorithm folds in two steps: the first one was based on the assumption that...
Cet article analyse les perceptions des conseillers agricoles de la région du sud-ouest de la province de Buenos Aires sur les transformations de leur métier et de leurs compétences. Il apporte une réflexion sur la diversification de l'exercice de ce métier, en rapport avec l'organisation de la profession d'ingénieur agronome qui a toujours tenté, ...
Skin contact has been hypothesized to contribute to human exposure to bisphenol A (BPA). We examinedthe diffusion and metabolism of BPA using viable skin models: human skin explants and short-term culturesof pig ear skin, an alternative model for the study of the fate of xenobiotics following contact exposure.14C-BPA [50–800 nmol] was applied on th...
X-ray tomography is used increasingly to study the macroporosity resulting from earthworm activity. However, macropores are not the only features visible on the images; other zones resulting from bioturbation by earthworms can be detected due to differences in greylevels. Four different soil cores were incubated with two earthworm species at two di...
The authors of the paper are interested in an environmental incentive payment mode for risk-averse contracting farmers. The incitement joins the environmental output produced by the farmer to his effort through an environmental contract reported to be motivating. However, we suppose an environmental output depending on a weather signal and we consi...
• Introduction Stem CO2 efflux (E s) is a significant component of total ecosystem respiration, but there is only scant information on seasonal variations in E s in tropical rainforests and on the main factors explaining these variations. • Methods We conducted a comprehensive 18-month study in French Guiana to try to better understand which enviro...
Terrigenous organic matter (TOM) transfer from a watershed to a lake plays a key role in contaminants fate and greenhouse gazes emission in these aquatic ecosystems. In this study, we linked physiographic and vegetation characteristics of a watershed with TOM nature deposited in lake sediments. TOM was characterized using lignin biomarkers as indic...
