Carol Sayuri-Nishisaka publishes MS research on soil nitrous oxide emissions from tropical tree crops in Brazil

In the winter of 2017, the Meredith Research Group had the pleasure of hosting Carol Sayuri-Nishisaka, a MS student with Dr. Acacio Aparecido Navarrete at the Federal University of São Carlos in Sorocaba, Brazil. Carol shared her expertise in quantitative PCR analysis of N2O cycling genes, which we used to study hotspot dynamics of N2O in the Biosphere 2 Tropical Rainforest. We were thrilled to contribute to her manuscript on differences in N2O emissions in tropical tree croplands versus their natural forest counterparts across the wet and dry seasons. Carol considered many soil physicochemical properties alongside N2O-cycling marker genes in her analysis. Especially interesting was Carol’s complementation of field-based insights with soil incubations in the laboratory. This revealed persistent differences in N2O cycling for soils collected in different seasons, even under identical conditions.

Congratulations Carol!
