Tropical dung beetle morphological traits predict functional traits and show intra-specific differences across land uses

1. Functional traits and functional diversity measures are increasingly being used to examine land use effects on biodiversity and community assembly rules. 2. Morphological traits are frequently derived from a mean value of many individuals, and used directly as functional traits. However, this approach overlooks the importance of intraspecific differences. 3. We collected morphometric data from over 1700 individuals of 12 species of dung beetle to establish whether morphological measurements can be used as predictors of behavioral traits. We also compared morphology among individuals collected from different land uses to identify if intra-specific differences in morphology vary among land use types. 4. We show that leg and eye measurements can be used to predict dung beetle nesting behavior and period of activity, and used this information to confirm the previously unresolved nesting behavior for Synapsis ritsemae. 5. We found intra-specific differences in morphological traits across ...
