N is the number of the frogs sampled for the Tb and db, while n is the number of sampled frogs for each population for Tsel. Thermal precision index (db) and thermal quality index (de) for each population.
Populations where the db index is close to zero indicate that the body temperature is close to the microenvironmental temperature. Likewise, de index near to zero indicates environmental thermal quality is very close to body temperature (Tb). Conversely, if db and de are different from zero, body temperature is far from microenvironmental temperature and thermal quality is not favorable to frogs. db, de, and Tsel are described in Materials and Methods.
