Thanks for stopping by! My name is Stefan Schreiber and I am a researcher and environmental data scientist at EnviroStats Solutions Inc. I am interested in plant ecophysiology, the boreal forest, data analysis and visualization.

From: Post-glacial biogeography of trembling aspen inferred from habitat models and genetic variance in quantitative traits

Palaeoclimatic habitat projections for trembling aspen based on the CCM1 general circulation model for (a) 21,000 years before present, (b) 14,000 years before present, (c) 11,000 years before present and (d) 6,000 years before present. The maps were created with ArcGIS v9.3 (http://esri.com).
