Table 3 in The Lyckholm acme of cephalopods - Review of the late Katian (Vormsi-Pirgu regional stages) Ordovician cephalopods of Estonia
收藏资源简介:
Table 3. Observed (S obs), and coverage-extrapolated species richness (qD) of cephalopod samples from Estonia (combined specimens from Teichert (1930) and herein), Saxby shore (combined localities Saxby (N) and Saxby (S)), Vormsi Regional Stage, Hosholm (= Mõisaholm) shore (combined Hosholm shore and Hosholm shore (tower)), Pirgu Regional Stage, and Vohilaid (E), Pirgu Regional Stage. The % of unknown species refers to qD as 100%. Lower (lcl) and upper (ucl) 95% confidence are given for qD. Note the different sample sizes. The Boda Limestone sample of cephalopods of Kröger (2013) is given for comparison. localitysample sizeS obsqD (lcl–ucl)% unknownEstonia total64690127 (76–177)30Saxby shore1473144 (10–78)30Hosholm shore1242736 (0–77)25Vohilaid shore (E)702129 (0–59)28Boda Lst5616580 (62–98)19
表3 为爱沙尼亚地区头足类(cephalopod)样品的观测物种丰富度(S_obs)与覆盖度外推物种丰富度(qD),该数据集整合了泰希尔特(Teichert)1930年的标本与本次研究采集的样品;采样点包括萨克斯比岸(整合萨克斯比北(Saxby (N))与萨克斯比南(Saxby (S))两个采样位点)、沃尔姆西区域阶(Vormsi Regional Stage)的霍什霍尔姆岸(=莫伊萨霍尔姆岸,整合霍什霍尔姆岸与霍什霍尔姆岸(塔台)两个采样位点)、皮尔古区域阶(Pirgu Regional Stage)的沃希莱德东(Vohilaid (E))。未知物种百分比以qD为基准,即占qD的比例。同时给出了qD的95%置信区间下限(lower confidence limit, lcl)与上限(upper confidence limit, ucl)。需注意各采样点的样本量存在差异。本次研究同时引用克罗格(Kröger)2013年报道的博达灰岩(Boda Limestone)头足类样品作为对照。 各采样点详细信息如下: | 采样位点 | 样本量 | 观测物种丰富度(S_obs) | 外推物种丰富度qD(95%置信区间) | 未知物种占比(%) | |------------------------|--------|------------------------|----------------------------------|-------------------| | 爱沙尼亚总计 | 646 | 90 | 127(76–177) | 30 | | 萨克斯比岸 | 147 | 31 | 44(10–78) | 30 | | 霍什霍尔姆岸 | 124 | 27 | 36(0–77) | 25 | | 沃希莱德东岸 | 70 | 21 | 29(0–59) | 28 | | 博达灰岩样品 | 56 | 16 | 58(62–98) | 19 |
