Photosynthetic and Hydraulic Traits for 12 Tropical Xerophytic Scrub Species

A dataset from a study on 12 tree and shrub species in a tropical xerophytic scrub on Margarita Island, Venezuela. It includes measurements of photosynthetic rate, transpiration, stomatal conductance, carbon and nitrogen isotope ratios in leaves and stems, and stem hydraulic conductivity. The data was authored by Eleinis Ávila-Lovera and last updated on May 7, 2026.

Use Cases

• Testing for coordination between stem hydraulic conductivity and photosynthetic traits based on measured variables like Ks and Aarea.
• Comparing long-term integrated water-use efficiency between leaves and stems based on δ13C isotope data.
• Analyzing variability in economic traits between photosynthetic stems and leaves across species.
• Modeling plant functional strategies for coping with seasonal drought in disturbed tropical ecosystems.

Strengths

• Includes data for 12 distinct tree and shrub species.
• Measures multiple key physiological traits (Aarea, E, gs, δ13C, δ15N, Ks) across two plant organs.
• Focuses on a threatened tropical xerophytic scrub ecosystem, a less-studied biome.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in size (799.3 KB), indicating limited scope.
