Traits data from juvenile trees exposed to a 50% reduction in canopy throughfall at the Caxiuan drought experiment, Brazil, 2017
A data set consisting of seventeen functional traits collected on 43 saplings from a Control and 33 saplings from a long-term drought experiment site in a tropical rainforest in NE Amazonia, Brazil. The experiment was designed to exclude 50% of the incoming rainfall to the soil and was conducted over a 1ha area, alongside the experiment there is a control (non- drought plot) of a corresponding size.
The samples were collected in 2017, fifteen years after the start of the experiment on trees with a diameter at breast height (1.3m) of 1-10cm. The purpose of the dataset was to assess if traits relating to plant metabolism (photosynthesis and respiration) and plant hydraulic processes had been significantly altered in trees growing under drought conditions.

Provenance & quality
The data was from August to September (dry season) in 2017. In total twenty species from nine genera were sampled, with replication at genera level on the drought and control plot. For each individual, we collected two branches from the top of the crown, representing the point maximally exposed to light and the 17 traits were measured off these two branches. The quality control processes were trait specific and the related papers detail how this was done.
