PATAGONIAN CLIMATE GRADIENT
In December 2019 I was funded to travel to Argentina to collaborate with Amy Austin and Lucia Vivanco, professors of Ecology at Universidad de Buenos Aires. Dr. Austin has established a climate gradient with paired pine plantation and natural vegetation sites in Patagonia.
We sought to determine the effect of climate and vegetation on leachable metals across a young (<100 yr old), tephra-derived precipitation gradient (250 – 2200 MAP) in the Patagonian Andes region of Argentina.
Previous work at these sites indicated both rainfall and vegetation were significant controls on soil C; we hypothesized that including leachable metals would increase explained variance in the soil C model.’
