Climate-driven changes in forest succession and the influence of management on forest carbon dynamics in the Puget Lowlands of Washington State, USA
Projecting the response of forests to changing climate requires understanding how biotic and abiotic controls on tree growth will change over time. As temperature and interannual precipitation variability increase, the overall forest response is likely to be influenced by species-specific responses to changing climate. Management actions that alter composition and […]
Ecoss does Ecosystem Science in the Park
Water plus soil makes mud, right? It’s definitely mud when it’s on the kitchen table at home. But for the Center for Ecosystem Science and Society (Ecoss), water plus soil makes paint, and it enjoyed centerpiece status on our table in Science in the Park in Flagstaff, last weekend, part […]
Resilience and vulnerability of permafrost to climate change
The resilience and vulnerability of permafrost to climate change depends on complex interactions among topography, water, soil, vegetation, and snow, which allow permafrost to persist at mean annual air temperatures (MAATs) as high as +2 °C and degrade at MAATs as low as –20 °C. To assess these interactions, we compiled existing […]
Greater ecosystem carbon in the Mojave Desert after ten years exposure to elevated CO2
Carbon dioxide is the main greenhouse gas inducing climate change. Increased global CO2 emissions, estimated at 8.4 Pg C yr−1 at present, have accelerated from 1% yr−1during 1990–1999 to 2.5% yr−1 during 2000–2009 (ref. 1). The carbon balance of terrestrial ecosystems is the greatest unknown in the global C budget because […]
