This research is focused on the physical, climatological, and human variables that affect the distribution of biodiversity across North America. The goal is to analyze the current physio-climatic envelopes of ecoregions, nature reserves, species and ecological systems, and to compare these ranges to those under hypothesized future climate scenarios. A primary objective is to assess the sensitivity of these conservation planning and management units to the potential effects of climate and land use change. A secondary objective is to develop and test the use of a continuous ecological classification surface as a coarse-filter surrogate and stratification layer for capturing the full range of biodiversity in continental reserve networks. The final objective is to develop an impedance surface and connectivity model to evaluate the ability of species and ecological communities to spatially adapt to climate change.
This research begins by developing a library of detailed physical, human, and climatological spatial data layers presumed to influence the distributions of species and ecological communities across North America. Spatial and multivariate analyses will be conducted on various stacks of gridded data layers to assess and characterize the physio-climatic range of all ecoregions, selected species, nature reserves, and proposed conservation sites across the continent. These results will be compared with the results of similar analyses conducted using several hypothesized climate change scenarios. Statistics and maps will be generated to quantify and illustrate the differences in distribution and representation of physio-climatic envelopes between current and future ecoregions, species ranges, and reserve networks. Finally, an impedance surface and connectivity model will be developed and analyzed to evaluate the ability of species and ecological communities to spatially adapt to climate change.
Results of these analyses will help conservation planners assess the risks of climate and land use change to current reserve networks, and help guide the design and management of future networks.
