Primate Sexual Size Dimorphism and Group Competition Across 143 Species

143 species of anthropoid and strepsirrhine primates are analyzed for relationships between sexual size dimorphism, mating system, and spatial competition proxies. The dataset, authored by Cyril C. Grueter and last updated in May 2026, includes files in CSV, R, and other formats totaling 140.4 MB. It supports a study suggesting that between-group competition, measured by home range overlap and encounter rate, is a stronger predictor of male-biased size dimorphism than mating system.

Use Cases

• Test hypotheses about sexual selection proxies based on mating system and spatial competition data.
• Model the relationship between sexual size dimorphism and home range overlap across primate species.
• Analyze the evolutionary pressures of between-group competition on male morphology.
• Conduct comparative phylogenetic analyses using the provided NEX and R files.

Strengths

• Includes data for up to 143 primate species, providing a broad comparative scope.
• Contains multiple file formats (CSV, R, NEX) suitable for different analytical workflows.
• Dataset is openly licensed under CC-BY-4.0 for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Description metadata is limited; actual data quality requires manual inspection after download.
