Insect Abundance and Environmental Data from Small Tributaries

44.0 KB of data and R scripts accompany a 2026 Oikos study on how basin context shapes insect fauna in small tributaries. The dataset includes abundance and environmental variables, with analysis focusing on nestedness, beta diversity, and dispersal within dendritic networks. It was authored by Adriano Melo and published under a CC BY 4.0 license.

Use Cases

• Analyze insect abundance patterns in relation to environmental variables from small tributaries.
• Calculate nestedness and beta diversity metrics for insect communities across a dendritic network.
• Model the role of dispersal and confluence effects on insect fauna composition using provided R scripts.
• Investigate how basin context shapes species assemblages in stream ecosystems.

Strengths

• Data is directly linked to a peer-reviewed publication in Oikos from March 2026.
• Includes R scripts for reproducibility of the ecological analyses.
• Dataset is published under a permissive CC BY 4.0 license for reuse.

Limitations

• The dataset is very small at 44.0 KB, indicating limited scope and likely a small sample size.
• Specific column names, row counts, and sample data are unavailable, hindering immediate assessment of structure.
• Geographic location and temporal coverage of the field sampling are not specified.
