Understanding ecological systems on the global scale will require an increase in preplanned, long-term, multi-site studies. This page describes an example of this type of research- a 10-year, 28-site experiment to test the effect of substrate quality and macroclimate on long-term decomposition and nutrient dynamics.


We would like to thank all of the people who cooperated with this project by putting out the litterbags, and then collecting them every year for 10 years.  We couldn't have done it without you!  The LIDET study was supported by LTER and NSF Ecosystem Studies Grants BSR-8805390, BSR-9180329, and DEB-9806493.
