本文报告1981年10月上旬在济南郊区的仓库和农村住房内,用格粉板法观察了家鼠的昼夜活动规律。在密度较高又无人干扰的仓库内,17～20时3个小时的踏格数就占昼夜踏格总数的28.1%,为褐家鼠一昼夜活动的最高峰。在住宅内,从20时至次晨4时8个小时的踏格数占昼夜踏格总数的74.5%。小家鼠与褐家鼠同时存在时,小家鼠的活动高峰时间与褐家鼠恰恰相反,7～17时10个小时小家鼠的踏格数占昼夜踏格总数的86.0%,而17时至次晨4时11个小时褐家鼠的踏格数占昼夜踏格总数的78.7%。作者认为,这是小家鼠对褐家鼠存在时的一种适应形式。
This article reports early in early 1981 in the suburbs of Jinan warehouse and rural housing, the use of grid powder law observed house rat circadian rhythm. In the high density and no interference in the warehouse, 17 ~ 20 hours three hours of the number of stride grid accounted for 28.1% of the total number of day and night, Rattus norvegicus for a day and night activities of the highest peak. In the home, the number of treads from 20:00 to 4:00 am at 8:00 am accounted for 74.5% of the total number of day-night strokes. Mus musculus and Rattus norvegicus coexist, Rattus norvegicus activity peak time and Rattus norvegicus exactly the opposite, 7 to 17 o’clock hours 10 hours Mus musculus accounted for 86.0% of the total number of day and night, and 17 When the next morning at 4:11 hours Rattus norvegicus accounted for 78.7% of the total number of day and night. The authors consider this to be a form of adaptation to the presence of Rattus norvegicus.
