Isotope Space: 
Studying animal niches using bulk stable isotope ratios

At the intersection between community and ecosystem ecology, trophic dynamics studies in aquatic and terrestrial environments seek to trace ecosystems energetic pathways as the food webs components are identified. We are using isotope niches of different bioindicators as a proxy of the complexity of neotropical landscapes. Since trophic interactions are directly or indirectly related to key ecosystem processes, this approach is becoming essential for assessing the global changes impacts on global ecosystems.
