Best fit values for the different strains fitted to the function 
. Parameter 
is in units of 1/degree Celsius, 
is in units of 1/day. Also shown are decay rates (units of 1/day) for each strain at 5 (
) and 40 (
) degrees Celsius. Numbers in parentheses following each strain indicate the genotype group (see main text). Numbers in parentheses following the other values indicate the rank of this value for each strain (with rank 1 given to the strain with the lowest value, corresponding to better persistence.)
