Spatial patterns and eco-epidemiological systems – part I: multi-scale spatial modelling of the occurrence of Chagas disease insect vectors

Autor: Emmanuel Roux, Annamaria de Fátima Venâncio, Jean-François Girres, Christine A. Romaña

Publikováno v: Geospatial Health, Vol 6, Iss 1, Pp 41-51 (2011)

Studies that explicitly and specifically take into account the spatial dimension within the study of eco-epidemiological systems remain rare. Our approach of modelling the spatial and/or temporal properties of the entomological and/or epidemiological

Publikováno v: Journal of environmental management. 203(Pt 1)

In addition to causing physical degradation and nutrient depletion, erosion of cultivated soils in the Amazon affects aquatic ecosystems through the release of natural soil mercury (Hg) towards lakes and rivers. While traditional agriculture is gener
