Twelve sites provided nocturnal soundscape recordings used to model sonotype richness against acoustic indices. The dataset contains Generalized Linear Models relating acoustic activity, evenness, spectral entropy, and soundscape saturation to total biophony and insect richness. Author Felipe do Carmo Jorge published the 5.5 KB Excel file on figshare under a CC-BY-4.0 license, last updated in May 2026.
Use Cases
- Modeling relationships between acoustic indices and biological richness based on the described predictor variables (ACT, AEI, Hf, Sm).
- Comparing the predictive power of individual acoustic indices versus a combined interaction effect for insect richness.
- Validating acoustic indices as proxies for biophony richness across different nocturnal soundscapes.
- Analyzing the contribution of insect sonotypes (crickets, grasshoppers, etc.) to overall soundscape biophony.
Strengths
- Includes four distinct acoustic indices (ACT, AEI, Hf, Sm) and a combined interaction effect as model predictors.
- Models two specific response variables: total biophony richness and insect richness.
- Data is openly licensed under CC-BY-4.0, facilitating reuse and redistribution.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The dataset is very small at 5.5 KB, indicating limited scope.
