Saproxylic Beetle Traits Across 28 Veteran Oak Sites

425 saproxylic beetle species from 28 veteran oak sites in 10 European countries, Turkey, and Israel. The dataset provides species-level trait data, including larval trophic group and body length, supporting analyses of taxonomic discovery biases and detection probability. It is associated with a 2025 publication in Insect Conservation and Diversity.

Use Cases

• Analyze body length distributions across larval trophic groups like mycetophagous or xylophagous to study size-based ecological niches.
• Model detection probability for species based on traits such as beetle family and body length.
• Assess Linnean and Wallacean shortfalls by examining taxonomic coverage across the 10-country geographic scope.
• Investigate correlations between larval trophic group categories and beetle family classifications.

Strengths

• Contains trait data for 425 distinct beetle species.
• Samples collected from 28 specific veteran oak sites across 10 countries.
• Includes analytically distinct variables: larval trophic group and body length.
• Associated with a peer-reviewed 2025 publication, ensuring academic rigor.

Limitations

• Small data volume at 25.7 KB, limiting the scale for complex machine learning.
• Unknown row count and column structure, complicating initial data assessment.
• Geographic scope is specific to veteran oak habitats, not representative of all beetle environments.
