At CREAF we study the relationships between the chemical and elemental compositions of species, communities, and soil with basic ecosystem function characteristics (flows of matter and energy, nutrient cycles, and growth strategies) and structure (diversity, characteristics of the trophic network, among others). We also use metabolomic analyses to study how the functioning of organisms or environment (e.g. soil) change under changing environmental conditions. Later, this information can be related with observed changes at different levels: changes in growth, mortality, herbivory, elemental composition and stoichiometric proportions, among others.
Ecotoxicological studies help us understand the relevance of different contaminants for trophic networks in order to evaluate impacts along spatial and temporal gradients. Finally, with metagenomic studies, we study the evolutionary responses of organisms and populations to environmental changes in the short, medium, and long term. This allows the addition of a temporal dimension to our studies, making them more innovative.
