Title: "Species Environmental Matching (SEM) Models for Invasive Species "
Abstract
The National Ecological Observatory Network (NEON) is a continental-scale research platform for discovering and understanding the impacts of climate change, land-use change, invasive species, and other factors on ecology. NEON will gather long-term data on ecological responses of the biosphere to changes in land use and climate and on feedbacks with the geosphere, hydrosphere, and atmosphere. NEON is a national observatory, not a collection of regional observatories. It will consist of distributed sensor networks and experiments, linked by advanced cyberinfrastructure, to record and archive ecological data for at least 30 years. Using standardized protocols and an open data policy, NEON will gather essential data for developing the scientific understanding and theory required to manage the nation’s ecological challenges. The problem is that there are no off-the-shelf protocols for scaling biological data from small study sites to continental scales. Assuming core sample areas and high resolution remote sensing are contained within a 20 km x 20 km area in each domain, the actual data “footprint” sampled represents < 0.3% of the area of the conterminous United States. An innovative, interdisciplinary approach to scaling biodiversity sampling is essential to meet NEON’s challenge of extrapolation from these small core areas up to continental scales. The greatest practical challenge NEON faces is integrating complex sensor networks and field experiments, with detailed observations and measurements of the changing biodiversity and ecosystem function within and across domains to continental scales.
