Activity Rhythms of Coexisting Red Serow and Chinese Serow at Mt. Gaoligong as Identified by Camera Traps.

摘要: Surveying the activity rhythms of sympatric herbivorous mammals is essential for understanding their niche ecology, especially how they partition resources and mechanisms coexistence. Over a five-year period, we conducted infrared camera-trapping to monitor coexisting red serow (Capricornis rubidus) Chinese (C. milneedwardsii milneedwardsii) in remote mountainous region Pianma, Mt. Gaoligong, Yunnan, China. Cameras captured images on 157 179 occasions, respectively. We used circular kernel density models analyze daily temporal variations ensure co-existence. Although overall levels patterns were similar, behavior partitioning among two species occurred during wet season. Compared with serows, serows exhibited less variable levels, patterns, as well feeding vigilance behaviors between seasons. When occasionally ranged together, tended alter pattern while significantly increased level. Red are exploitative competitors but coexist by altering when contact changing season, enabling
