Calculate accuracy of temperature regulation
Description
This function determines the degree to which ectotherms experience body temperatures outside their set-point range, better known as the accuracy of temperature regulation (db) as described by Hertz et al. (1993). Descriptive statistics are automatically computed as well.
Usage
calculate_db(tb, tset_low, tset_up)
Arguments
tb |
A vector containing body temperature measurements. |
tset_low |
Lower boundary of a species or population set-point range that was determined through thermal preference trials in a temperature gradient. |
tset_up |
Upper boundary of the set-point range. |
Value
Degree to which ectotherms experience body temperatures outside their set-point range (db), and associated descriptive statistics.
