The general objective of the project is to recognize the patterns of variability of the stable isotope (δ13C and δ15N) baselines for protein fraction in terrestrial temperate ecosystems: in plants and mammalian herbivores. In particular, the project main focus is checking if more-than-one isotopic baselines may occur within a community (of plants, or of mammalian herbivores) in an ecosystem. Our preliminary data suggests that this may be the case. If this hypothesis will be confirmed, it would mean that several independent baselines should be included in the isotope flux models, even for a single ecosystem.
