Japanese Rhinoceros Beetle Horn Allometry and Shape Data

Norikuni Kumano's dataset supports a study on how pupal temperature affects the sexually selected weapon of the Japanese rhinoceros beetle. It includes individual-level measurements of body size, horn length, longevity, and morph classification, alongside elliptic Fourier analysis files quantifying horn shape. The 309.0 KB collection contains CSV data files and R code to reproduce the original statistical analyses.

Use Cases

• Analyzing the relationship between pupal temperature and horn length-body size allometry based on individual-level measurements.
• Investigating the effect of temperature on male morph frequency and adult longevity using the provided classification and timing data.
• Quantifying changes in horn shape using the provided normalized elliptic Fourier descriptors from dorsal and lateral outlines.
• Reproducing statistical analyses and figures from the original manuscript using the included R script.

Strengths

• Includes the complete R script (Takadama_analysis_code.R) to reproduce all statistical analyses and figures from the manuscript.
• Contains raw data files for individual-level measurements and derived shape analysis descriptors, enabling full replication.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• Column-level documentation is absent; field semantics must be inferred from the description and R code after download.
