Offspring growth and survivorship in the woodlouse Porcellionides pruinosus
Abstract
Offspring from two groups of female Porcellionides pruinosus (Brandt), a synanthropic woodlouse, were reared individually under laboratory conditions of excess food and constant temperature. Birth weight, which varied both within and between broods, affected survivorship but was not significantly correlated with offspring growth. In both groups offspring size at 101 days was independent of birth weight and there was only a weak relationship between birth weight and offspring survivorship. Analysis of survivorship for offspring in size classes suggested a minimum size threshold for survival, below which few offspring were produced. This size threshold and a strong correlation between fertility and female fitness indicates possible stabilizing selection on offspring size in these animals. Significant intraspecific variation in offspring size would thus be a rapid, potentially adaptive, phenotypic response to environmental conditions where minimum investment requirements to ensure offspring survival are maintained.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
