Resting metabolic rate is repeatable, but does not affect call characteristics, in the gray treefrog Hyla chrysoscelis.

ABSTRACT: Consistent among-individual variation in behavior is widespread and often has consequences for fitness. However, the mechanistic basis of repeatable variation in behavior is less understood. Metabolic rate is a likely candidate to drive repeatability in behavior because energy metabolism can limit behavioral expression. There are competing hypotheses for the relationship (or lack thereof) between levels of maintenance metabolism such as resting metabolic rate (RMR) and the expression of behaviors. On the one hand, RMR may show a negative relationship with behavior if higher RMR limits energy that can be allocated to other processes. On the other hand, RMR may positively correlate with behavior if high RMR leads to greater energy production ability. To test these hypotheses, we examined the
