Abstract

It has been brought to our attention that there was an error in computations for our paper Kulbaba et al. (2019). Specifically, we used aster analyses of records of components of fitness for cohorts representing three populations of Chamaecrista fasciculata, each grown in its home location in 3 years to obtain estimates of mean lifetime fitness and additive genetic variance for fitness. The measure of lifetime fitness was the number of seeds produced per individual seed planted. However, it is not feasible to obtain every fruit before it dehisces and releases its seeds. For this reason and also because in this and many other species fruits may be numerous, it is common practice to obtain seed counts from a subset of fruits. Aster methodology can account for such subsampling of a fitness node, and our aster models did so. The error arose in the process of obtaining estimates of mean fitness and additive genetic variance for fitness. This part of the earlier analysis did not scale up from the subsampled fruits to obtain estimates of the total number of seeds from all the fruits an individual produced. Our reanalysis correcting this error shows that it did not affect our qualitative conclusions, although numerical values differ. We have archived a corrected analysis at https://zenodo.org/record/7013786. ACKNOWLEDGMENTS We thank A. Peschel for discovering this error and informing us of it; we thank F. Shaw for checking the derivative needed for the standard error calculation.
