Application of fungal and bacterial production methodologies to decomposing leaves in streams

Article Abstract:

The validity of several methods used in estimating fungal and bacterial production in leaves decomposing in a woodland stream is investigated. Several parameters are considered in the study, including the time of incubation, effect of aeration, concentration of the radiolabeled substrate and acetate incorporation. Results show that the methods can produce accurate estimates of bacterial and fungal growth rates in streams provided all pertinent data are given.

Comparison of fungal activities on wood and leaf litter in unaltered and nutrient-enriched headwater streams

Article Abstract:

The study has quantified and compared fungal biomass, production, assimilation and microbial respiration on leaves and wood both at the substrate scale and at the ecosystem scale on an annual basis. Despite a lower fungal activity on wood than on leaves, fungi are equally important in processing both leaves and wood in streams.

Fungal growth, production, and sporulation during leaf decomposition in two streams

Article Abstract:

The pH and alkalinity of streams may affect the fungal decomposition of leaves in addition to the amount of phosphorus and nitrogen in the water. The leaves of the white oak and yellow poplar decomposed more quickly in a hardwater stream at a pH of 8.0 than in a softwater stream ata pH of 6.7.
