Gall Maker Populations and Enemies Over Six Years Across 15 Sites

A six-year study by Denon Start at the University of Toronto tracks over 3,000 individual univoltine gall makers and their enemies from 15 populations. The dataset likely contains records of demography, species interactions, and natural selection before and after an extreme environmental event. It examines how such 'Black Swan' events can increase spatial variation in ecological and evolutionary outcomes.

Use Cases

• Modeling population demography based on gall maker and enemy counts across 15 sites.
• Analyzing changes in species interaction networks following an extreme environmental event.
• Studying spatial variation in natural selection and evolutionary change driven by environmental homogenization.
• Investigating the relationship between environmental drivers and enemy attack rates on gall makers.

Strengths

• Longitudinal data covering a six-year study period.
• Includes over 3,000 individual organisms across 15 distinct populations.
• Focuses on a specific, documented extreme event and its ecological consequences.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
