Showing items 45775 through 45783 of 73379.Energy fluxes, including net radiation, latent heat flux and sensible heat flux were determined on clear days during the vegetative period in four types of land cover: wet meadow, pasture, arable field, and an artificial concrete surface.
Few economic analyses examine land trusts, their decisions, and the land-trust "industry," despite their growing importance.

A dynamic fugacity model was developed to simulate the spatial and seasonal variations of PAHs in Haihe Plain, China. The calculated and measured concentrations exhibited good consistency in magnitude with deviations within a factor of 4 in air and 2 in soil.
Sub-Saharan Africa is large and diverse with regions of food insecurity and high vulnerability to climate change. This project quantifies carbon stocks and fluxes in the humid forest zone of Ghana, as a part of an assessment in West Africa.

Hood Canal, Washington, USA, is a poorly ventilated fjord-like sub-basin of Puget Sound that commonly experiences hypoxia. This study examined the influence of watershed soils, vegetation, physical features, and population density on nitrogen (N) export to Hood Canal from 43 tributaries.
Increases in respiration rates following management activities in croplands are considered a relevant anthropogenic source of CO₂. In this paper, we quantify the impact of management events on cropland respiration fluxes of CO₂ as they occur under current climate and management conditions.
Many tropical wetlands threatened by land use changes, or modifications in hydrological regime require effective management policies and implementation to protect them.
