Uncertainty Analysis of the Dispersal Models used in Species Distribution Modelling

Peer Reviewed Abstract
Optional Fields
Species distribution models (SDMs) are one of the most important GIScience research areas in biogeography and the primary method used to study the potential effects of climate change on speciesí distributions and ranges. However, models rarely incorporate measures of accessibility for future habitat, while the differences among dispersal models that are implemented to achieve this are poorly understood. Here we compare different dispersal models and their implementations for 50 British bird and 29 North American tree species. Our results show that the choice of dispersal model used greatly impacts both the accuracy and uncertainty of projected distributions, and represents an area of important future research.
