WebWe examined the abundance and distribution of neutrophilic, microaerophilic Fe (II)-oxidizing bacteria (FeOB) in aquatic habitats of a highly weathered, subtropical coastal catchment where Fe biogeochemistry is of environmental significance. Webyfrom Thimijan and Heins, 1983. Solar energy can be transmitted, reflected or absorbed by the atmosphere and the greenhouse covering. The transmitted portion is needed for plant growth, but only a fraction (1 - 5%) is actually utilized by the plant. The remainder is absorbed and re-emitted as thermal radiation
