Variation in demographic and physiological attributes of life-history is
thought to fall on one single axis, a phenomenon termed the Pace-of-Life.
A slow Pace-of-Life is characterized by low annual reproduction, long life
span and low metabolic rate, a fast Pace-of-Life by the opposite
characteristics. The existence of a single axis has been attributed to
constraints among physiological mechanisms that are thought to restrict
evolutionary potential. In that case, physiological traits should covary
in the same fashion at the levels of individual organisms and species. We
examined covariation at the levels of individual and subspecies in three
physiological systems (metabolic, endocrine and immune) using four
stonechat subspecies with distinct life-history strategies in a common
garden set-up. We measured basal metabolic rate, corticosterone as
endocrine measure, and six measures of constitutive immunity. Metabolic
rate covaried with two indices of immunity at the individual level, and
with corticosterone concentrations and one index of immunity at the
subspecies level, but not with other measures. The different patterns of
covariation among individuals and among subspecies demonstrate that links
among physiological traits are loose and suggest that these traits can
evolve independent of each other.
