Paleovegetação da Ilha Grande (Rio de Janeiro) no Holoceno através do estudo de fitólitos e isótopos do carbono (Paleovegetation of Ilha Grande (Rio de Janeiro) in the Holocene through the study of phytoliths and carbon isotopes)

A study of Ilha Grande, Brazil, reveals that the island's vegetation has remained predominantly arboreal and stable over the last 4,000 years, mirroring current conditions. Using phytolith analysis and carbon isotope measurements, researchers found a consistent dominance of C3 plants, indicative of rainforest cover, suggesting long-term bioclimatic equilibrium. While erosion due to high rainfall and relief gradient has altered fossil phytoliths, the study highlights the resilience of Ilha Grande's Atlantic Forest ecosystem under varying environmental pressures.
