The Barbary striped grass mouse (Lemniscomys Barbarus) has been described as a diurnal and photoperiodic rodent, but no reliable data exist on the daily and seasonal rhythmicity of body temperature (Tb). In this study, Tb patterns were determined in different groups of males maintained in captivity under different regimes of photoperiod. Tb was recorded with surgically implanted iButton temperature loggers. The work shows the existence of a strong and bimodal daily Tb rhythm in this species

... e external synchronizer is the lightdark cycle; it's also confirmed the diurnal and photoperiodic character of this animal. The highest values of Tb were registered during the lightphase in the contrary of nocturnal species. This kind of experimental work corresponds to the theme of the ACMLIS'17 conference by means of, on one side, the use of the temperaturesensitive intraabdominal implants for monitoring core body temperature, an approach of machine learning, and on the other side, the final aim of the work which is to better understand the more complicated and sophisticated of intelligent systems, the central nervous system.

T r possible role of sex steroids in seasonal changes of daily rhythm of Tb. Moreover, because the recording of Tb was continuous throughout the experiment, we also check if daily torpor or hibernation bouts were expressed during prolonged exposure to SP conditions.
