Abstract:The weight of the internal organs and the length of the digestive tract of small mammals are plastic and can be used to approximately indicate the animal adapting to the environment. By comparing the change of internal organs of plateau zokor (Myospalax baileyi) along the altitude gradient, the adaptability of plateau zokor to the environment was assessed on the basis of the morphology and structure. The result showed that the wet heart weight and dry heart weight, dry weight of spleen and lung, wet stomach weight and dry stomach weight, and wet cecum weight of male plateau zokor were significantly positive correlated with the altitude, however, the wet kidney weight, and length of large intestine were significantly negative correlated with the altitude. The fresh heart weight and dry heart weight, fresh weight and dry weight of the lungs, wet stomach weight, fresh cecum weight and cecum length of female plateau zokor were significantly positive correlated with the altitude, and the fresh weight and dry weight of liver, dry spleen weight, dry weight and fresh weight of kidney, and dry large intestine weight, and length of large intestine were significantly negative correlated with the altitude. Therefore, the correlation between the organ and elevation of plateau zokor indicated that this species adopted compensatory adaption against the different living environment, energy demand, oxygen content, and pathogens.
