TL;DR: A quantitative and mechanistic basis for evaluating the potential effects of atmospheric pollutants on physiology and growth of seedlings of loblolly pine, an important timber species in southern commercial forests, was evaluated in laboratory and controlled field studies as mentioned in this paper.

TL;DR: In this paper, the Throughfall Displacement Experiment sustained both increased (+33; wet) and decreased (−33; dry) throughfall into an upland oak forest in Tennessee.

TL;DR: In this paper, the authors incorporated a soil temperature module into a Terrestrial ECOsystem (TECO) model by accounting for surface energy budget, snow dynamics, and heat transfer among soil layers and during freeze-thaw events.

TL;DR: In this article, potential enzyme activity rates were determined across seasons and with depth in peat samples collected from the Marcell Experimental Forest in northern Minnesota, USA, and the temperature dependence, assessed by activation energy, was quantified for three hydrolytic enzymes involved in nutrient cycling at up to 15 temperature points ranging from 2.5°C to 65°C.

TL;DR: In this article, manipulation experiments are used to evaluate the potential impacts of a range of climate change scenarios on highly valued ecosystems, such as ecosystem productivity, biogeochemical cycling, and the availability of water resources.
