抽象的。在世界许多地区，鹿和野猪等有蹄类动物的活动范围不断扩大，数量不断增加。迫切需要对这些过剩的人口进行监管。对于解决这些过多种群问题的有效扑杀计划，了解动物活动模式的信息至关重要。为了确定影响梅花鹿日常活动模式季节性的因素，我们通过人类干扰较低的日本北海道洞爷湖中之岛的相机陷阱研究了梅花鹿的活动。我们估计了四个时间段（黎明、黄昏、白天和夜间）的活动模式，并评估了每个时段天气条件对活动模式（相机陷阱率）的影响。鹿在黎明、黄昏和夜间的活动呈现出明显的季节规律，9月份为高峰，而白天的活动规律在所有季节都保持不变。 7-10月和7-11月黎明和黄昏的活动分别高于白天。虽然梅花鹿的活动可能会受到天气条件的影响，但没有季节一致性。我们的研究表明，人类干扰可能会减少白天的活动并增加夜间的活动。

Abstract. Ungulate populations such as deer and wild boars have been expanding in range and increasing in number throughout many areas of the world. Regulation of these overabundant populations is urgently needed. For an effective culling program addressing these overabundant populations, it is essential to have information on the activity pattern of animals. To determine the factors affecting seasonality of daily activity pattern in sika deer, we studied deer activity through camera traps on Nakanoshima Island, Lake Toya in Hokkaido, Japan, where human disturbance is low. We estimated activity pattern during four time periods (dawn, dusk, day, and night), and evaluated the effects of weather conditions on activity pattern (camera trap rate) for each period. Deer activity at dawn, dusk and night showed clear seasonal patterns, with peaks in September, while the activity pattern during the day was constant in all seasons. The activity at dawn and dusk tended to be higher than that at day during July–October and July– November, respectively. Although the activity of sika deer may be influenced by weather condition, there was no seasonal consistency. Our study reveals that human disturbance might decrease diurnal activity and increase nocturnal activity.
