Data from: Relative contributions of offspring quality and environmental quality to adult field performance

Determinants of adult performance, such as growth and survival, are
influenced by extrinsic, environmental and intrinsic, phenotypic factors.
The relative importance of extrinsic and intrinsic factors, while
ecologically relevant, is rarely estimated simultaneously. We estimate the
relative contributions of offspring size (intrinsic) and various
environmental factors (extrinsic) on adult performance in the marine
colonial bryozoan Watersipora subtorquata. We used a variance partitioning
approach for both new and previously published data, enabling us to
examine the performance of over 1000 individuals in the field. We found
offspring size to explain relatively little variation in adult
performance. Of the environmental factors taken to account, temporal
variation and an environmental gradient had the strongest influences.
