Phenotypic selection on physiological parameters is an underrepresented
topic in studies of evolutionary biology. There is especially a lack of
studies involving invertebrate organisms. We studied the repeatability of
the standard metabolic rate (SMR) and the effect of individual variation
in SMR on the subsequent winter survival in a terrestrial shell-bearing
mollusc, the white-lipped snail (Cepaea hortensis) in mid-Norway. SMR was
measured twice during the autumn and – after an experimental overwintering
at controlled conditions – twice during the following spring. We found a
significant repeatability of SMR over all three time periods tested, with
a clear effect of time, with a high repeatability of 0.56 over 4 days
during spring, 0.44 over 12 days in the autumn and 0.17 over 194 days from
autumn to spring. That SMR is a repeatable physiological trait across the
winter period during which a possible selection might occur, suggests that
SMR could be a potential target of natural selection. We indeed found that
the autumn SMR significantly influenced the probability of survival during
the winter period, with a combination of a positive linear (P = 0.011) and
a quadratic stabilizing (P = 0.001) effect on SMR. Our results hence
support the view that metabolic rate is an important physiological
component influencing the fitness of an organism.
