AnimalTraits

AnimalTraits aggregates standardized, curated measurements of body mass, metabolic rate, and brain size across terrestrial animal taxa to support large-scale comparative analyses in ecology and evolutionary biology.

Key Features:

• Extensive Taxonomic Coverage: Includes tetrapods, arthropods, molluscs, and annelids, covering nearly 2,000 species across approximately 1,000 genera.
• Standardized Data: Records measurements in standardized units while preserving original empirical metrics within each record to allow precise data transformations.
• Rich Metadata: Provides extensive metadata fields to enable filtering and refinement of datasets for targeted analyses.
• Supportive Tools and Scripts: Includes R scripts to aggregate standardized observations into species-level trait values.

Scientific Applications:

• Comparative Studies: Enables cross-species and cross-taxa comparative analyses of body mass, metabolic rate, and brain size to investigate evolutionary patterns, ecological dynamics, and physiological adaptations.
• Ecological Research: Facilitates examination of relationships among body size, metabolic demands, and brain function across environmental contexts.
• Evolutionary Biology: Supports analysis of trait evolution across lineages and the construction of phylogenetic models.

Methodology:

Data are sourced from original empirical publications and standardized into consistent units, and provided R scripts aggregate standardized observations into species-level trait values.
