Carbon dioxide, water vapor, and energy fluxes were measured using eddy covariance (EC) methodology over three adjacent evergreen forests in southern Washington State to identify stand-level age-effects on ecosystem exchange. The sites represent Douglas-fir forest ecosystems at two contrasting successional stages: old-growth (OG) …

Wharton, S., Chasmer, L., Falk, M., Paw U, K.T.
Variability in three Pacific teleconnection patterns are examined to see if net carbon exchange at a low-elevation, old-growth forest is affected by climatic changes associated with these periodicities. Examined are the Pacific Decadal Oscillation (PDO), Pacific/North American Oscillation (PNA) and El Niño-Southern Oscillation …

This study examines how stand age affects ecosystem mass and energy exchange response to seasonal drought in three adjacent Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests. The sites include two early seral (ES) stands (0-15 years old) and an old-growth (OG) (~ 450-500 years old) forest in the Wind River Experiment Forest, …

Krishnan, P., Black, T. A., Jassal, R. S., Chen, B., Nesic, Z.
The seasonal and interannual variability of gross ecosystem photosynthesis (Pg) and
ecosystem respiration (Re), and their relationships to environmental variables and stand
characteristics were used to explain the variation of eddy-covariance-measured net
ecosystem productivity (FNEP) of three different-aged Douglas-fir stands …

Similar nonsteady-state automated chamber systems were used to measure and partition
soil CO2 efflux in contrasting deciduous (trembling aspen) and coniferous (black spruce
and jack pine) stands located within 100km of each other near the southern edge of the
Boreal forest in Canada. The stands were exposed to similar climate …

Recent studies have demonstrated direct methane emission from plant foliage under aerobic conditions, particularly under high ultraviolet (UV) irradiance. We examined the potential importance of this phenomenon in a high-elevation conifer forest using micrometeorological techniques. Vertical profiles of methane and carbon dioxide …

Ecosystem level ozone (O3) fluxes during four different years were examined at a subalpine forest site in the Colorado Rocky Mountains. The local mountain–valley wind system and the proximity of the Denver Metropolitan area leads to high summertime ozone episodes on many afternoons. The timing between these episodes and the ecosystem …
