Dendro Training

How does Pinus ponderosa water use before and after the North American Monsoon impact the δ¹⁸O measured in wood cellulose in the American southwest?

In the southwestern U.S. the North American Monsoon (NAM) delivers summer precipitation from July – September and the rest is provided as snowmelt in early spring. Both periods serve as an important water source for plants, but due to the heterogeneous nature of the NAM, not all locations within the region receive precipitation, leading to differences in soil moisture.
