Environmental Controls on Canopy Foliar N Distributions in a Neotropical Lowland

32 Distributions of foliar nutrients across forest canopies can give insight into their plant functional 33 diversity and improve our understanding of biogeochemical cycling. We used airborne remote 34 sensing and Partial Least Squares Regression (PLSR) to quantify canopy foliar nitrogen (N) 35 across ~164 km 2 the mechanisms and feedbacks involved, and how 51 shifts in climate may translate to changes in forest function.
