摘要：掌握蒙古野驴(Equus hemionus)活动节律、活动范围和适宜生境分布,有助于理解蒙古野驴适应环境变化的生存策略。本研究于2021-2023年夏季(6-8月)在卡拉麦里国家公园候选区,利用红外相机技术开展蒙古野驴夏季水源利用规律研究。于2022-2024年,对卡拉麦里国家公园候选区野外放归的6匹蒙古野驴佩带GPS颈圈进行跟踪监测。利用GPS颈圈数据开展蒙古野驴50%和95%Kernel夏季活动范围研究。同时,基于红外相机和GPS颈圈数据,利用BIOMOD2物种分布模型模拟蒙古野驴夏季适宜生境分布,并评估国家公园候选区保护空缺。结果表明:(1)安装在卡拉麦里国家公园候选区的红外相机夏季共记录到5,996张蒙古野驴独立照片。其中,白天2,825张、夜间2,212张、清晨459张、黄昏500张;(2)蒙古野驴在夏季水源利用方面表现出全天活动强度相对稳定的特征,为昼夜兼性动物,夜间活动指数略高于其他时间段,活动高峰出现在23:00至翌日04:00,清晨和黄昏时分活动强度略低;(3)6匹蒙古野驴夏季50%K活动范围为4.98-162.18 km^(2),平均活动范围为76.34±69.36 km^(2);夏季95%K活动范围为27.67-2,117.72 km^(2),平均活动范围为892.95±908.91 km^(2);(4)BIOMOD2模拟结果表明,卡拉麦里国家公园候选区蒙古野驴夏季适宜生境总面积为1.94×10^(4) km^(2),76.97%的适宜生境处于国家公园候选区范围内。本研究初步掌握了卡拉麦里国家公园候选区蒙古野驴夏季利用水源规律、活动范围和适宜生境分布,丰富了行为生态学知识,可为国家公园候选区制定针对蒙古野驴及其栖息地的保护管理对策提供科学依据。
Aims:Understanding the activity patterns,range,and suitable habitat distribution of Equus hemionus is essential for assessing its survival strategies in response to environmental changes.Methods:In this study,we used camera trapping to survey water resource utilization patterns of Equus hemionus during summer season(June to August)from 2021 to 2023 in Kalamaili National Park candidate area.Meanwhile,we studied the kernel activity range of six rescue released Equus hemionus fitted with GPS satellite collars,tracking them from 2022 to 2024 in Kalamaili National Park candidate area.Finally,we combined camera trapping and GPS satellite data,and used the BIOMOD2 model to assess the suitable habitat distribution of species during the summer season,and evaluated the conservation gap within national park candidate area.Results:The results showed that:(1)we obtained 5,996 independent detections of Equus hemionus at water resource during summer season.Among them,2,825 independent-detections were recorded during the daytime,2,212 in the nighttime,459 in the morning and 500 at nightfall.(2)Equus hemionus exhibited random usage of water sites at nighttime(wi=1.32),daytime(wi=0.94),morning(wi=0.98)and nightfall(wi=1.07)in different time periods;the activity index at nighttime was slightly higher than in other three periods,with a peak activity period occurring between 23:00 and 04:00,while activity levels were relatively lower during the morning and nightfall periods;(3)the 50%kernel activity range was 4.98-162.18 km^(2),with a mean of 76.34±69.36 km2;the 95%kernel activity range was 27.67-2,117.72 km^(2) with a mean of 892.95±908.91 km^(2);(4)based on BIOMOD2 models,the suitable habitat area for Equus hemionus in Kalamaili National Park candidate area during summer was 1.94×10^(4) km^(2),with 76.97%of the suitable habitat within national park candidate area boundaries.Conclusion:Our study has preliminarily obtained the water resource utilization patterns,activity range and suitable habitat distribution of Equus hemionus in Kalamaili National Park candidate area.These findings enrich our understanding of behavioral ecology,and provide a scientific basis for developing conservation measures to protect the endangered species and their habitats in national park candidate area.
