Species Distribution Modeling
The Relative Impacts of Projected Climate and Land-use Change on Conterminous United States Bird Species from 2001 to 2075
Species distribution modeling was used to assess the relative impacts of climate and land-use change on fifty bird species for the conterminous United States. Species presence data, current and projected land-cover data, current and projected climate data, and topographic data were used in a maximum entropy modeling framework to assess impacts of climate and land-cover on bird distributions for 2001, and for multiple 2075 scenarios.
The following provides access to output data for this assessment, including:
Maxent uses spatially explicit predictor variables (covariates) to score presence likelihood for each pixel. Variables used in this assessment include current (2001) and projected (2075) climate data, current (2001) and projected (2075) land-cover data, and topographic data. The following zip file contains ERDAS .img files for each of the predictor variables used in this assessment, as well as a readme that describes the data.
Tabular data of assessment results are provided in the Excel spreadsheet found below. Information contained in the spreadsheet included all quantitative modeling data used to construct the tables and graphics in the paper. Each spreadsheet page provides the output data used to construct figures 1-5 in the paper. This includes:
