Comparing Social Structure and Brain Size in Bat Species

Why do the authors have to control for body size allometry before comparing the relationships between social structure and brain/testes sizes among bat species?

To control for allometry in the species-level analyses, analysis of covariate (ANCOVA) was used with body size treated as a covariate (Pitnick et.al 2006).

Mean Residual Brain Mass and Testes Mass for Bat Species

Explain completely the meaning and interpretation of the mean residual in brain mass and testis mass for bat species relative to the occurrence fo female promiscuity and their mating system?

The main purpose is to produce residuals from regression of 1n brain mass or 1n testis mass on 1n body mass, with regressions executed discretely by family as partial phylogenetic control (Pitnick et.al 2006). .
