Research in ecology has traditionally been funded for short periods of time and performed at single sites, conditions not conducive to projects addressing much greater time and geographic scales. NSF's support of an experimental emphasis on long-term ecological research seeks to alleviate this discontinuity and use available research resources more effectively to provide a more stable platform for the ecological sciences.
