Shrub-Layer Diversity Is Reduced Yet Overall Productivity Increased with Climate Warming Experimental treatments at DOE’s SPRUCE warming study in northern Minnesota show cumulative changes in peatland shrub-layer vegetation. Summary Project results indicate an overall increase in shrub-layer vegetation suggesting that warmer future climates could enhance productivity of woody peatland vegetation, but at a cost to … Continue reading Shrub-Layer Diversity Is Reduced Yet Overall Productivity Increased with Climate Warming
