Abstract
Metabolic rate is a crucial trait shaping organismal physiology,
adaptability, and ecological roles, with extensive studies on its
allometric relationship with body size. Larger organisms have lower
mass-specific metabolic rates, a pattern observed across taxa and
ontogeny. Despite numerous hypotheses, no universally accepted theory
exists on the biological mechanisms of metabolic allometry, particularly
for suborganism-level. We investigated the relationship between
body size and metabolic rate as well as mitochondrial characteristics
in isolated gill tissue of the marine mussel Mytilus edulis. Results indicated that metabolic allometry patterns
observed at the organismal level did not manifest at the tissue level.
Our study also revealed that while the density of mitochondria in
gill tissue did not differ significantly between large and small
individuals, area and perimeter of mitochondrial cross-sections increased
significantly with body mass. This finding contrasts with mammalian
data, suggesting potential phylogenetic differences. Larger mussels
exhibited higher mitochondrial activity, supporting a link between
mitochondrial morphology, activity, and growth rates. Our results
highlight the importance of mitochondria in mollusk metabolism and
growth, warranting further exploration into the mechanisms translating
mitochondrial characteristics into growth rates.
