| 摘要: |
| 为阐明喀斯特地貌对雉类空间生态位与时间生态位的塑造作用，本研究利用红外相机监测广西雅长兰科植物国家级自然保护区的白鹇(Lophura nycthemera)与黑颈长尾雉(Syrmaticus humiae)的分布位点，并采用物种分布模型(Species Distribution Models,SDMs)与无人机遥感衍生的地表起伏度(Relief Degree of Land Surface,RDLS)进行分析。结果表明：两种雉类在喀斯特生境中均呈现高度破碎化的空间分布，纳入RDLS后，白鹇与黑颈长尾雉的潜在适宜栖息地面积分别减少55.64%和95.26%，且斑块结构连通性显著降低；两种雉类存在显著的日活动节律分化，白鹇白天活动强度均较高，尤其是在7:00—11:00时段，而黑颈长尾雉活动呈双峰模式(6:00—11:00及17:00—20:00)，体现了时间生态位的分化，但月活动强度无显著差异。活动节律的可塑性可能是白鹇广泛分布的基础之一。本研究揭示了在喀斯特地貌下，RDLS不仅制约了两种雉类的分布格局，还导致了其活动模式在时间上的分化，建议在保护管理中充分考虑地形复杂性与物种活动节律。 |

| Abstract: |
| To elucidate the shaping role of karst landforms on the spatial ecology and temporal niches of pheasants,this study monitored Lophura nycthemera and Syrmaticus humiae by using infrared camera traps in the Guangxi Yachang Orchid National Nature Reserve,and analyzed the data by combining Species Distribution Models (SDMs) with UAV-derived Relief Degree of Land Surface (RDLS).The results showed that both pheasant species exhibited highly fragmented spatial distribution patterns within karst habitats.Upon incorporating RDLS,the potential suitable habitat areas for L.nycthemera and S.humiae decreased by 55.64% and 95.26%,respectively,and the patch structural connectivity decreased significantly.There was a significant divergence in the daily activity rhythms of the two pheasant species.The activity Level of L.nycthemera was generally high in the daytime, especially in the period 7:00—11:00,whereas the activity of S.humiae exhibited a bimodal pattern (6:00—11:00 and 17:00—20:00),reflecting temporal niche differentiation.However,no significant difference was observed in monthly activity intensity.This plasticity in activity rhythms may be one of the foundations for the widespread distribution of L.nycthemera.This study reveals that under karst landforms,RDLS not only constrains the distribution patterns of the two pheasant species,but also produces temporal differentiation in their activity patterns.It is recommended that terrain complexity and species activity rhythms should be fully considered in conservation management. |
