Insect Acoustic Richness and Soundscape Metrics from Two Australian Reserves

A dataset containing between- and within-site similarity metrics for two Australian reserves, Hidden Vale and Grandchester. It is based on insect sonotype richness and four acoustic indices calculated from audio clips recorded over five non-consecutive summer nights. The dataset was authored by Felipe do Carmo Jorge and last updated on May 15, 2026.

Use Cases

• Compare multivariate community centroids between sites based on PERMANOVA R² and p-values.
• Test homogeneity of multivariate dispersion between sites using PERMDISP p-values.
• Assess within-site acoustic homogeneity using mean pairwise distances.
• Explore relationships between insect richness (sonotype count) and acoustic indices (ACT, AEI, Hf, Sm).

Strengths

• Includes four distinct acoustic indices (ACT, AEI, Hf, Sm) calculated from the same audio clips.
• Provides specific statistical outputs (PERMANOVA R², p-values; PERMDISP p-values) for hypothesis testing.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• Dataset is very small (5.5 KB), indicating limited scope.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
