Raw data from the Egan et al. (2011) study on phenotypic selection on gall size produced by Belonocnema treatae on a host tree (Quercus fusiformis). These data were downloaded from Dryad and then formatted for use in this R package.
Galls consists of the following variables:
relative fitness, based on the emergence/survivorship of the host-specific gall-former Belonocnema treatae (
BtreataeEmergence) on it host plant (the plateau live oak Quercus fusiformis).
absolute fitness, based on the emergence/survivorship of the host-specific gall-former Belonocnema treatae (
BtreataeEmergence) on it host plant (the plateau live oak Quercus fusiformis). 1 = emerged/survived, 0 = no emergence.
diameter of the galls produced by B. treatae on its host plant, in units of millimeters and measured to the nearest 0.01 mm.
year that the data were collected (either 2004 or 2008)
individual identification of the tree that was sampled. Each tree was treated as a separate population.
identication number of the bag/enclosure that was treated as a blocking factor within each tree.
data.frame with 14283 observations and 6 variables
These data were obtained from the Excel spreadsheet that is available on Dryad: http://datadryad.org/resource/doi:10.5061/dryad.1js1n, and are associated with Egan et al. (2011).
