Abiotic Constraints On The Establishment Of Quercus Seedlings In Grassland
Danner, B. T., Knapp, A. K.

High evaporative demand and periodic drought characterize the growing season in midwestern grasslands relative to deciduous forests of the eastern US, and predicted climatic …

Oxygen Isotope Content Of CO2 in Nocturnal Ecosystem Respiration: 2. Short-Term Dynamics Of Foliar And Soil Component Fluxes In An Old-Growth Ponderosa Pine Forest
Bowling, D. R., McDowell, N. G., Welker, J. M., Bond, B. J., Law, B. E., Ehleringer, J. R.

The oxygen isotope contents (δ18O) of soil, xylem, and leaf water and ecosystem respiration were studied in a ponderosa pine forest during summer 2001. Our goal was to assess whether δ18O of CO2could be used to quantify the relative contributions of soil and foliar respiration to total nocturnal …

Partitioning Of Water Flux In A Sierra Nevada Ponderosa Pine Plantation
Kurpius, M., Panek, J., Nikolov, N., McKay, M., Goldstein, A.

The weather patterns of the west side of the Sierra Nevada Mountains (cold, wet winters and hot, dry summers) strongly influence how water is partitioned between transpiration and evaporation and result in a specific strategy of water use by ponderosa pine trees (Pinus …

Airflows And Turbulent Flux Measurements In Mountainous Terrain: Part 1. Canopy and local effects
Turnipseed, A. A., Anderson, D. E., Blanken, P. D., Baugh, W. M., Monson, R. K.

We have studied the effects of local topography and canopy structure on turbulent flux measurements at a site located in mountainous terrain within a subalpine, coniferous forest. Our primary aim was to determine whether the complex terrain of the site affects the accuracy of eddy flux measurements from a practical perspective. We …

Reduction Of Forest Floor Respiration By Fertilization On Both Carbon Dioxide-Enriched And Reference 17-Year-Old Loblolly Pine Stands
Butnor, J. R., Johnsen, K. H., Oren, R., Katul, G. G.

Elevated atmospheric carbon dioxide (CO2e) increases soil respiration rates in forest, grassland, agricultural and wetland systems as a result of increased …

On Comparison Of Modeled Surface Flux Variations To Aircraft Observations
Song, J., Wesely, M.

Evaluation of models of air–surface exchange is facilitated by an accurate match of areas simulated with those seen by micrometeorological flux measurements. Here, spatial variations in fluxes estimated with the parameterized subgrid-scale surface (PASS) flux model were compared to flux variations seen aboard aircraft above the …

Environmental Controls On Net Ecosystem-Level Carbon Exchange And Productivity In A Central American Tropical Wet Forest
Loescher, H. W., Oberbauer, S. F., Gholz, H. L., Clark, D. B.

Difficulty in balancing the global carbon budget has lead to increased attention on tropical forests, which have been estimated to account for up to one third of global gross primary production. Whether tropical forests are sources, sinks, or neutral with respect to their carbon balance with the atmosphere remains unclear. To address …
