Degradation of weathered diesel fuel by microorganisms from a contaminated aquifer in aerobic and anaerobic microcosms
Culture-based assessment of the effects of chlorpyrifos on multiple meiobenthic copepods using microcosms of intact estuarine sediments
Impact of elevated ammonium on reproduction in two Hawaiian scleractinian corals with different life history patterns
Persistence of bioluminescent Rhizobium meliloti strains L1 (RecA super(-)) and L33 (RecA super(+)) in non-sterile microcosms depends on the soil type, on the co-cultivation of the host legume alfalfa and on the presence of an indigenous R. meliloti population

Use of temporary pond microcosms for aquatic toxicity testing: Direct and indirect effects of endosulfan on community structure
Effect of exposure regime on the internal distribution of cadmium in Chironomus staegeri larvae (Insecta, Diptera)
By influencing nutrient mineralization in the soil, decomposers may affect the performance of plants and their associated herbivores. The strength of aboveâ€“belowground linkages may therefore depend on the availability of nutrients in ecosystems. We investigated the dependency of decomposer- and leaf-herbivore-mediated changes in plant performance on soil nutrient availability in microcosm systems. In separate treatments, Poa annua was used as host plant for the herbivore and was grown in combination with different herb species: Plantago lanceolata, Trifolium repens, and Sanguisorba minor. At three different levels of nutrient availability, the impact of Collembola (Folsomia candida) and aphids (Rhopalosiphum padi),...
