2. Spatial biodiversity analysesCan help to answer Where are the most diverse or most uniqueresources and why? Are they threatened by land use changes orclimate change? Where should action be taken to most efficientlyconserve diversity or tap useful variation? VisualizationData Field studies Existing records Species distribution modeling can complementThis presentation: Case studies about the uses ofspatial analysis tools on tropical tree species 3. Freely available tools and datasets DIVA-GIS software www.diva-gis.org Special features for analyzing biodiversity data Free spatial data Training manual (Scheldeman & van Zonneveld 2010) w ww.bioversityinternational.org/training/training_materials/gis_ma The Global Biodiversity Information Facility (GBIF) 312,669,756 species records (15 Nov 2011) www.gbif.org WORLDCLIM Current, future and past climate data www.worldclim.org 4.
