资源简介：
Water residence time of ridge-top trees was studied using the deuterium tracer technique combined with sap flow in 2012. Fixed depth sap flow probes were used (2 pairs in each tree) and sap flow was monitored from April to November. Trees were injected with deuterium tracer, and the tracer was measured in leaf condensate on subsequent days. Leaves were sampled regularly by climbing trees and 50-foot-tall scaffolding. Leaves were placed in sealed plastic bags under lamps in greenhouse upon returning to the lab each day and condensate was removed from bags and stored in sealed vials. Condensate was run on a Los Gatos water isotopic analyzer in the lab.
