Leachingnization and invertebrate feeding. Leaching is defined as the abiotic removal of soluble substances, among them phenolics, carbohydrates and amino acids. The rate of leaching and the composition of leachates are influenced by humidity and temperature experienced by leaves between their detachment fr

Decomposition of Fine Particulate Organic Matterr heterotrophic microorganisms, and as a carrier of nutrients, metals and other chemicals. In streams, FPOM is derived from leaf litter, algae and other organisms by physical, chemical, and biological processes. In addition, FPOM can be formed by the flocculation of dissolved organic matter (DOM). T

Coarse Particulate Organic Matter Budgetsate organic matter (CPOM) budget for a stream, CPOM inputs, outputs and storage can be measured according to methods described in other chapters of this book. The chapter presented here describes two approaches to construct a budget from these data. All budget components (i.e. CPOM storage; vertical

Total Proteinerived from microbial cells and excretions. The first step to estimate protein concentrations is the extraction of protein from leaf litter and any associated microorganisms. Tannins form complexes with proteins, which tend to be stable near neutrality and dissociate with increasing alkalinity or in

Free Amino Acids directly accessible soluble compounds such as amino acids. The concentration of free amino acids in plant litter is dynamic and is significantly affected by degradation patterns and leaching. This chapter describes the procedures for the efficient extraction of free amino acids from plant tissues a

In addition, minor amounts of pectin and protein are also present, but only represent a small fraction to the secondary xylem of plants, which forms the bulk of terrestrial plant biomass and provides a substrate for litter-degrading microorganisms.
