Abstract

In the Negev Desert highlands of S Israel, porcupines optimized winter (October-March) activity for minimal exposure to moonlight, but moonlight avoidance waned thereafter and disappeared by late summer (August-September). Rain curtailed activity, but there was no correlation between duration of activity and minimum near-ground temperatures. Individual variation in activity was large in all seasons. Adult-sized animals (14.1 ± 3.0 kg body mass) averaged 7.0 ± 0.4 h surface activity year-round, but this peaked at 9.2 ± 1.3 h in late summer when nearly all night hours were used. In winter, activity averaged 6.7 ± 0.8 h and porcupines were active for longer periods on dark nights than on moonlight nights. -from Authors
