Power Analysis

To estimate how many experimental nests I would need to set up, I carried out a power analysis.. The pilot study was too limited in number of replicates to generate an accurate estimate of the effect size of edge effects, so effect sizes were gathered from a variety of papers who had performed similar experiments \cite{KOTZE_2007,Cooper_1998,Vaaland_Burkey_1993,TEMPLE_1988}. An average was taken which indicated a low effect size (w=0.256), and using the default values of  p = 0.05 and power 0.8, indicated that  showed N=119.8, indicating 120 nests need to be used for the full experiment.
