Brazilian scientists sampled 800 trees across 63 Amazon locations; their atomic fingerprinting model can exclude 92% of the forest when tracing suspicious timber
Wood samples being collected for cellulose isotope analysis. Credit: CENA-USP By analyzing the atomic signatures of 800 trees collected from 63 locations across the Amazon, Brazilian researchers have developed an isotopic mapping model that can rule out 92% of the rainforest when tracing suspected illegal timber.The project, led by Professor Luiz Antonio Martinelli at the…
