Life-History Traits of Two Poplar Defoliators Under Competition and Food Restriction

Laboratory experiment data from 2026 by Zhao Hongting, investigating the coexistence mechanisms of two moth species, Micromelalopha sieversi and Clostera anachoreta. The dataset includes measurements of survival, pupation, growth, fecundity, and feeding behavior under mixed- and single-species rearing with varying food supply. It is shared under a CC-BY-4.0 license as a 243.8 KB XLSX file.

Use Cases

• Modeling population dynamics based on survival and fecundity data under different competition scenarios.
• Analyzing feeding behavior and temporal activity patterns based on light/dark condition experiments.
• Comparing nutritional efficiency and growth rates between insect species and larval instars.
• Investigating the effects of resource availability (ad libitum vs. restricted) on life-history trait trade-offs.

Strengths

• Data from controlled laboratory experiments allows for direct comparison of treatments.
• Includes multiple measured traits: survival, pupation rate, pupal weight, fecundity, developmental duration, and nutritional indices.
• Explicitly compares two competition scenarios (mixed- vs. single-species) and two resource conditions.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 243.8 KB size indicates a limited scope, likely containing summary or aggregated experimental results rather than raw observations.
