| Arcsin transformation was conducted for all behavioral data before analysis. |
| Prior to any statistical analysis, variables with non-normal distributions were transformed to logarithms, and percentage values were arcsin transformed. |
| Linear regression gave reasonably good fits to the arcsin transformed data from most times and was, therefore, used to facilitate comparison among the data sets. |
| Proportions were converted to a normal distribution before analysis using an arcsin transformation after first correcting for zero values. |
