Food-web graph index data contains node and edge counts for arthropod species in maize fields. The dataset includes arthropod samples collected via pitfall traps, yellow traps, and plant assessments across different maize development stages in 2007-2008. It was authored by Zoltán Pálinkás and is available under an Open Access license.
Use Cases
- Calculate keystone species importance based on the K index described in the summary.
- Analyze trophic link complexity using in-degree and out-degree values for species.
- Compare arthropod community structure across different maize development stages (V8, V12, VT, R3).
- Assess the impact of genetically modified maize events on food-web topology.
- Model weed coverage interactions with arthropod populations across growth stages.
Strengths
- Includes data from three distinct collection methods (pitfall traps, yellow traps, plant assessment) for cross-validation.
- Captures temporal dynamics across five specific maize development stages.
- Provides quantitative keystone species ranking via the K index metric.
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.
