Photosynthetic Temperature Response for Nine Common Tree Species in Singapore

Nine common tree species planted in Singapore were surveyed for key photosynthetic traits and their short-term temperature response. The dataset, created by Li Ming Rachel Teo and last updated in May 2026, shows a threefold interspecific variation in photosynthetic capacity (Vcmax ranging from 20 to 60 μmol m–2 s–1) and a large discrepancy in temperature sensitivity among species.

Use Cases

• Modeling urban carbon sequestration potential based on species-specific photosynthetic capacity (Vcmax).
• Assessing species suitability for urban cooling projects based on their photosynthetic temperature sensitivity.
• Calibrating or validating photosynthesis models using measured temperature response data for tropical tree species.
• Informing tree selection for Singapore's 'One Million Trees' project and similar initiatives in Southeast Asia.

Strengths

• Provides specific photosynthetic capacity (Vcmax) ranges (20 to 60 μmol m–2 s–1) for nine species.
• Focuses on the nine most popular tree species planted in a major tropical city-state (Singapore).
• Explicitly measures and compares short-term temperature response, a key trait for climate impact modeling.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is very small (19.5 KB), indicating limited scope and likely a small sample size.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
