In the 1981 water year, bulk precipitation was primarily a solution of dilute H2SO4, and SO42-was the dominant anion in tbroughfall and soil leachates in two eastern Tennessee deciduous forests…. More

Fluxes of carbon dioxide, water vapor and energy were measured above and below a temperate broad-leaved forest and a boreal jack pine (Pinus banksiania Lamb.) forest by the eddy covariance… More

Ecologists are expected to play an important role in future studies of the biosphere/atmosphere exchange of materials associated with the major biogeochemical cycles and climate. Most studies of material exchange… More

The penetration of diffuse sky radiation via canopy opening into a fully-leafed tulip poplar forest was estimated from canopy structure data obtained from canopy photographs and from sky brightness distribution… More

Soil hydraulic properties at eight depths in a Fullerton cherty silt loam (a clayey, kaolinitic, thermic Typic Paleudult) profile were derived from measurements of water content with a calibrated neutron… More

Forests in the south-eastern United States experienced a prolonged dry spell and above-normal temperatures during the 1995 growing season. During this episode, nearly continuous, eddy covariance measurements of carbon dioxide… More

A study of carbon cycling within the floor of a mixed deciduous forest included estimates of litterfall, litter standing crop, root turnover, lateral root standing crop, and measurements of gaseous… More
