Diurnal, seasonal and sex variations in rectal temperature of African giant rats ( Cricetomys gambianus, Waterhouse)

Diurnal, seasonal and sex variations in rectal temperature of African giant rats ( Cricetomys gambianus, Waterhouse)

(1) Rectal temperature ( T r) was measured in captive African giant rats ( Cricetomys gambianus, Waterhouse), live-trapped in the Savannah during the harmattan, hot-dry and rainy seasons with the aim of determining diurnal, seasonal and sex patterns. (2) Mean (±SEM) T r in the morning (37.16±0.04 °C...

Zusammenfassung:(1) Rectal temperature ( T r) was measured in captive African giant rats ( Cricetomys gambianus, Waterhouse), live-trapped in the Savannah during the harmattan, hot-dry and rainy seasons with the aim of determining diurnal, seasonal and sex patterns. (2) Mean (±SEM) T r in the morning (37.16±0.04 °C) was lower ( P0.05) between afternoon and evening T r during the harmattan and rainy seasons, but the difference was significant ( P
