1. Post-maturation growth leading to indeterminate growth patterns is
widespread in nature. However, its adaptive value is unclear. Life history
theory suggests this allocation strategy may be favoured by temporal
pulses in the intensity of mortality and/or the capacity to produce new
tissues. 2. Addressing the origin of indeterminate growth and the
variability of growth patterns, we studied the growth of duck mussels,
Anodonta anatina, a pan-European unionid, in 18 Polish lakes. For each
population the sex, size and age of collected mussels were measured to
estimate Bertalanffy’s growth curve parameters. We integrated information
on A. anatina mortality rates, lake trophy, biofouling by zebra mussels,
Dreissena polymorpha, and the prevalence of parasitic trematode larvae to
identify selective conditions in lakes. 3. We found two sources of
mortality in A. anatina populations, pertaining to adverse effects of
zebra mussel biofouling and trophy state on mussel survival. Additionally,
populations with heavier biofouling presented a smaller abundance of
parasites, indicative of a relationship between filtering intensity and
contraction of water-borne trematode larvae by filtering A. anatina. 4.
Consistently for each sex, populations with a greater trophy-related
mortality were characterized in A. anatina by a smaller asymptotic size
Lmax, indicative of a life history response to mortality risk involving
early maturation at a smaller body size. In all populations, females
featured higher mortality and larger asymptotic size vs. males. 5. Our
findings support a theoretical view that adaptive responses to selection
involve adjustments in the lifetime resource allocation patterns. These
adjustments should be considered drivers of the origin of indeterminate
growth strategy in species taking parental care by offspring brooding in
body cavities.
Duck mussels were sampled from 18 lakes in Poland (18 populations). For
each populations, sex-specific values were calculated: Bertalanffy's
growth curve parameters, overgrowth by zebra mussels, infestation by
trematodes, mortality rates. For each lake also a trophy index was
calculated. Deposited are two datasets. Dataset 1 shows quantitative
measures of the intensity of overgrowth in the studied lakes. Dataset 2
shows population and sex specific values of all studied traits that were
used for hypothesis testing in the paper linked to these datasets.
