Summary
1. Ecological niche and species distribution models (ENMs and SDMs) are widely used in macroecological studies to investigate the potential geographic distributions of invasive species, the effects of climate change on past, present and future species distributions as well as the evolution of ecological niches. For many of these studies, estimating the similarity of different ENMs and SDMs is critical to evaluate the robustness of models.
2. We implement previously described randomization tests for evaluating the similarity of ENMs and SDMs in a package of three programs/scripts using the Python Programming Language. Our implementation is modular and flexible. It can be used with a variety of existing ENM and SDM algorithms and can be integrated into high-throughput analyses using a command-line shell (e.g. the Bash shell that is found on many Unix-like operating systems).
3. We demonstrate the application of NichePy using distributional data of two Anolis species from Hispaniola. An analysis integrating NichePy and openModeller, including a simple and straight-forward approach to ensemble modelling, is outlined.
