Webconcurrent environmental changes are scarce. A synthesis of results from one of the most compre-hensive grassland global change experiments to date, the Jasper Ridge Global Change Experiment, suggests that interactions among climate change drivers are rare and have limited influence on biomass production in the long term (Dukes and others 2005).

WebThe Jasper Ridge Global Change Experiment, a long-term study of grassland responses to climate and at-mospheric changes, was initiated in the autumn of 1997. Eight replicate blocks, each containing four cir-cular plots 2 m in diameter, were established at an annual-dominated grassland site that has remained un-disturbed for >25 yr. Web1 ian. 2010 · Simulated global change experiments at Jasper Ridge have also provided insight into C–nutrient interactions in grasslands. In particular, several field-based experiments have shown that CO 2 doubling does not necessarily simulate productivity of California grasslands; rather, the strength and sign of net primary productivity (NPP) …
