Physical effects on the microbial colonization and decomposition of plant litter in an oligotrophic lake were studied in Toolik Lake, Alaska. Colonization, measured by adenosine triphosphate (ATP) analysis, and decomposition, measured by weight loss,

The comparative mineralization of eight polycyclic aromatic compounds in five soils collected from an abandoned coal tar refinery in eastern Ohio was determined. The soils showed differences only in total extractable hydrocarbon content of the soil c

Phosphorus fertilization of a pristine tundra river for four consecutive sum- mers dramatically changed biological processes and populations at all trophic levels. At the primary producer level, both algal biomass and productivity increased and chlor

Manned exploration of Mars may result in the contamination of that planet with terrestrial microbes, a situation requiring assessment of the survival potential of possible contaminating organisms. In this study, the survival of Bacillius subtilis, Az

This work addressed the impact that the rhizosphere has on the biodegradation of foreign organic compounds. This was examined with live plants grown in a sewage sludge amended agricultural soil and a woodlot soil. Microcosms were designed that contai

In Antarctica, there exists a complete microbial ecosystem that lives hidden within the pore spaces of sandstone (cryptoendolithic). Studying microbes within this solid matrix has presented certain technical problems which have been overcome. This ha

A fourth-order arctic river was experimentally enriched with phosphate (7.7 ± 7.0 μ g 1−1) to determine the effect of such a loading (equivalent to a community of 10,000 people) upon the trophically important biofilm. The effect upon a light-grow

The microbial mineralization of [U-14C-ring] linear alkylbenzene sulfonate (LAS) and [U-14C-ethoxylate] linear alcohol ethoxylate (LAE) was examined in 11 soils. These soils differed in their physical-chemical properties and were obtained from geogra
