We are an integrative research group that uses stable isotopes as a central tool in basic ecological studies (from population to ecosystem levels), but especially that applies this knowledge on environmental assessment and forensic science combining isoscapes with genetics, chemistry, big data, remote sensing and modeling in our research initiatives.

 

We are committed to providing high-quality research on stable isotope data interpretation to further knowledge in the environmental sciences for the Neotropics.

Synergistic impacts of co‐occurring invasive grasses cause persistent effects in the soil‐plant system after selective removal

January, 2020

We conclude that invasive species of the same functional group have similar types of effects in native ecosystems, but the magnitude of the impact was largely dependent on invasive species biomass and cover. Where multiple invasive species are present, research and management of invaded ecosystems should tackle the interacting effects of co-occurring invaders.

Impact of exotic pastures on epigeic arthropod diversity and contribution ofnative and exotic plant sources to their diet in the central Brazilian savanna

December, 2019

Our isotopic models show that woodland savanna ar-thropods feed preferentially on native C3-plant sources, while also showing signs of exotic C4 sources in theirdiet. These outcomes indicate that foraging or dispersal events may occur between habitats since arthropodscaptured in pastures also show signs of native sources in their diet.

Background and the use of isoscapes in the Brazilian context: essential tool for isotope data interpretation and natural resource management

March, 2019

The incorporation of isoscapes may broaden the understanding of mechanisms and processes of major biogeochemical cycles in Brazil, assist in solving crimes, track illicit drug origins, help to detect wild animal trafficking, and increase Brazilian knowledge about the hydrological cycle and animal migration patterns in the Neotropics.
