Project abstract: The soil fauna of a tropical montane rain forest: regulatory forces and functioning in the decomposer system
Project description: The proposed project investigates four topics. (1) The response of bacterial and fungal feeding soil invertebrates to increased nutrient (nitrogen and phosphorus) supply in a montane tropical rain forest in Ecuador along an elevation gradient from 1000 to 3000 m (Nutrient Manipulation Experiment). As representatives of bacterial and fungal feeders Testacea and Oribatida, but with less intensity also Nematoda and Collembola will be investigated. (2) Effects of increased nutrient (nitrogen and phosphorus) supply on the decomposition of litter and roots of representative tree species along an elevation gradient from 1000 to 3000 m. (3) The role of litter diversity for the diversity of bacterial (Testacea) and fungal (Oribatida) feeding soil animals. (4) The genetic variation of two representative species of bacterial (Testacea) and fungal (Oribatida) feeding soil animal species with a temperate to tropical distribution.
