Galls: Gall size

In MorphoFun/psa: Phenotypic Selection Analysis tools

Description

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:

w

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).

W

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.

gallSizeDiameter_mm

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

year that the data were collected (either 2004 or 2008)

tree

individual identification of the tree that was sampled. Each tree was treated as a separate population.

bagPerReplicate

identication number of the bag/enclosure that was treated as a blocking factor within each tree.

Usage

Galls

Format

data.frame with 14283 observations and 6 variables

Source

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).

# Look at the structure of the data.frame
str(Galls)

# Run a linear regression with wr as the response and the phenotypic traits as the predictors
