2017 data from a long-term drought experiment in a Brazilian tropical rainforest assesses functional traits on 76 saplings. Seventeen traits relating to plant metabolism and hydraulics were collected fifteen years after the experiment's start. The dataset compares 43 saplings from a Control plot with 33 from a 1ha drought plot designed to exclude 50% of incoming rainfall.
Use Cases
- Analyze drought-induced changes in photosynthesis and respiration trait values between Control and drought plot saplings.
- Model relationships between plant hydraulic process traits and long-term throughfall exclusion.
- Compare trait distributions across the 76 sampled juvenile trees with a diameter at breast height of 1-10cm.
Strengths
- Data from a 15-year long-term experimental manipulation (50% throughfall exclusion) in a 1ha tropical rainforest plot.
- Seventeen functional traits measured per sapling, focusing on metabolism and hydraulics.
- Direct comparison between 43 Control and 33 drought-exposed saplings from the same site.
Limitations
- Small sample size of 76 total saplings may limit statistical power for some analyses.
- Single temporal snapshot from 2017; lacks time-series data on trait changes.
- Geographic scope is limited to one experimental site in NE Amazonia, Brazil.
