Diversidad y funciones ecosistémicas en el desierto del monte

Sumario:Diversity affects ecosystem function because of the differences of species in resource use and requirements. Increasing species numbers may cause a more complete use of resources. Biodiversity losses may cause negative effects on ecosystems, comparable to UV radiation, climate change and increasing CO2.In drylands, characterized by a high temporal variability of resource availability, biodiversity will have crucial effects on resource use, productivity, an stability of ecosystems. We propose that functional and taxonomic diversity affects different processes or ecosystem funcitons, tending to optimize resource use such as water and nutrients, and increase primary productivity. We will evaluate this hypothesis with observational studies in vegetation patches in diversity gradients of the Monte desert. As predictor variables, we will estimate functional and species diversity. As response variables, we will estimate indicators of ecosystem processes related to water and nutrient use, decomposition, fine sediment capture, and primary productivity.
