Session Title: Linking microbial enzymes to ecosystem processes in aquatic ecosystems
website: http://aslo.org/santafe2010/
Mineralization of organic matter by heterotrophic microorganisms creates the trophic base for detritus food webs, drives global carbon and nutrient cycles, and mediates plant production and atmospheric composition. The proximate agents of organic matter decomposition are extracellular enzymes that deconstruct plant and microbial cell walls, depolymerize macromolecules, and ultimately produce soluble substrates for microbial assimilation. At the organismal scale, expression of these activities is controlled by environmental signals linked to substrate availability and population density. At large scales, activities track biogeochemical trends linked to climate and other variables. This session invites papers that use enzymatic approaches to investigate ecological processes on molecular to ecosystem scales. Topics of interest include environmental control of extracellular enzyme activity, enzyme stoichiometry, and enzyme activities in relation to community composition, ecosystem metabolism, and biogeochemical cycles.
