Ocelot density estimate comparison.
收藏资源简介:
Study sites where camera-trap surveys in combination with capture-recapture models have been used to estimate ocelot density. Studies are listed chronologically. Density is reported in ocelots per 100 km2. Asterisk (*) indicate that the density is the average of density estimates from more than one surveys in the same area. Method refers to how the effective surveyed area was estimated (HMMDM—buffer width of half the mean maximum distance moved of all animals captured in more than one camera-trap station were added to the survey trapping area; Telemetry—home range size estimates based on radio-tracked animals were used to inform the buffer width added to the survey trapping area, SCR—information on capture history of individuals in combination with spatial information of captures were used to directly estimate density).
本数据集收录了采用红外相机陷阱调查结合捕获-再捕获模型估算虎猫种群密度的研究样地。所有研究按时间顺序排列。种群密度以每100平方千米的虎猫个体数为统计单位。星号(*)代表该密度值为同一区域内多次调查所得密度估计值的平均值。方法项说明有效调查面积的估算方式:HMMDM——将在多个红外相机站位捕获的所有动物的平均最大移动距离的一半作为缓冲带宽度,叠加至调查诱捕区域范围;无线电遥测(Telemetry)——基于无线电追踪动物得到的家域面积估算结果,确定添加至调查诱捕区域的缓冲带宽度;空间捕获-再捕获(SCR)——结合个体捕获历史与捕获位置的空间信息,直接估算种群密度。
