Appendix B. Methods for meteorological variables.
In all six study plots, we recorded relative humidity and temperature every 10 minutes with a temperature and relative humidity sensor CS215 placed 5 m above the ground under the canopy attached to a CR 1000 data-logger and a 16/32 AM416 channel multiplexer (Campbell Scientific, Logan, Utah). Solar radiation above the canopy was recorded every 10 minutes using a LI200X pyranometer (LICor, Campbell Scientific, UT, USA) and daily precipitation was measured with a 200 mm diameter manual rain gauge NovaLynx Model 260-2510 (NovaLynx Corporation, Auburn, CA); both sensors were located in an open field meteorological station on Barro Colorado Island, 3 km away from the study plots (data provided by the Smithsonian Tropical Research Institute).
