Plant-Herbivore-Parasitoid Food Webs Across a Forest Edge Gradient in New Zealand

273.9 KB of data on a tritrophic food web comprising plants, herbivores, and parasitoids sampled across habitat edges between native southern beech and non-native pine plantation forests in New Zealand. Guadalupe Peralta published this dataset on figshare in 2026, which also includes interaction data from an experimental herbivore density reduction via aerial insecticide spraying over 20 hectares.

Use Cases

• Modeling edge effects on food web structure based on habitat gradient sampling
• Analyzing tritrophic interaction networks based on plant-herbivore-parasitoid data
• Evaluating the impact of herbivore density reduction via insecticide spraying on parasitoid populations

Strengths

• Includes experimental manipulation data from a 20-hectare insecticide spraying trial
• Sampled across a specific habitat gradient between native beech and plantation pine forests
• Published under the CC-BY-4.0 license, facilitating open reuse

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific New Zealand study sites
