To compare Tr (Table 1) and various physiological and behavioural variables (Table 2) during the time of FMR measurements a mixed model was used with animal as a random factor to adjust for repeated measurements and month (i.e. FMR measurement periods) as a fixed factor using the MIXED procedure in SAS version 9.4 (SAS, Inst. Inc., Cary, NC).
