Ecological Niche Modeling (ENM)

The workflow offers an extensible framework for analyzing or predicting the impact of environmental changes on the distribution of biodiversity. Especially in combination with data aggregation workflows like the Taxonomic Data Refinement Workflow (DRW), the ENM workflows facilitate the analysis of species distribution patterns over large geo-temporal, taxonomic, and environmental scales. Examples for applications are studies of species adaptations to climate change, dynamic modeling of ecologically related species, identification of regions with accumulated risk for invasion, potential for restoration, or natural protected areas.

ENM Statistical Workflow (ESW)

The ENM statistic workflow (ESW) allows the computation of the extent and intensity of change in species potential distribution through computation of the differences between two raster layers using the R statistical environment (R Core Team 2013). The difference file is computed from two input files (in this case present projection and 2050 projection). The difference between each corresponding raster cell value is computed and stored in the difference file, regardless of the input files’ geographical extent and origin.
