Abstract
Male and female Mongolian gerbils (Meriones unguiculatus) carrying three coat color alleles, agouti, sandy, and black, were tested for 15 min under three cage temperature conditions, warm (35-40 degrees C), neutral (20 degrees C), and cold (0-5 degrees C). A frequency count of scratching, face and body wash, belly/side rubs, and shaking was taken of these animals' activities during the test sessions. Sex differences were not evident but coat color and age temperature affected the belly/side rubs and shaking activities. There were also effects of cage temperature but not coat color on face/body wash and scratching. It appears that animals with these coat color variants manifest disparate patterns of COBS behavior when encountering different thermal environments.
