Andropogon Gerardi Trait and Drought Response Data from 25 Great Plains Populations

Jack Sytsma's dataset contains data from a greenhouse common garden experiment on the grass Andropogon gerardi. It includes measurements of 17 functional traits from 25 populations sourced across broad temperature and precipitation gradients in the US Great Plains, along with genetic data and experimental drought response data from eight populations. The dataset was last updated on 2026-05-22.

Use Cases

• Modeling the relationship between climate-of-origin and plant functional traits based on precipitation and aridity gradients.
• Analyzing genetic differentiation among populations using genotyped data to understand the heritability of traits.
• Comparing drought response strategies between wet- and dry-adapted populations based on biomass and photosynthesis measurements.
• Validating greenhouse-measured traits against field observations to assess environmental plasticity.

Strengths

• Includes data from 25 distinct populations across a broad climate gradient (4–21°C, 350–1400 mm yr⁻¹).
• Measures 17 functional traits per plant, covering morphology, physiology, and performance.
• Combines trait data with genetic data and experimental drought treatments for eight populations.
• Uses a common garden design to separate genetic and environmental effects on trait variation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset size is listed as 0.0 B, indicating a very limited scope or potential metadata issue.
