Abstract

Robust estimates of species population abundance are necessary for the success of conservation plans and species management strategies. In the present study, our main objective was described a combination method to estimate of detection probability (P) at hands of estimating population size of adult and subadult individuals N. kaiseri. N. kaiseri is listed as a critically endangered species because of its highly fragmented breeding habitat and also because it occupies a small range during its reproductive period. We did determine P in our study, which would have allowed us to estimate population size, we conducted the visual encounter surveys at various times of morning, noon and afternoon during March until April, which is likely when the detection probability reaches its highest value for three years. The observation possibility of the Lorestan newts is highest in the evening approximately 60% and lowest in the noon about 46% while detection probability in Morning was about 50% (P value ≤ 0.05). We surveyed a total of 55 sites in the southwestern of Iran for N. kaiseri. The Lorestan newts used a considerable variation of Aquatic habitats. Population size of the Lorestan newt (adult and subadult individuals) by P estimated at least 14 709 ± 247. However, these findings suggest that the true population size there is not big. It is essential that we coherent conservation program such as captive management as a stopgap component of an integrated port conservation effort, population of N. kaiseri in small sites could become extinct.

使用综合方法估算Lorestan Newt，Neurergus kaiseri（Schmidt，1952）的种群数量和检测概率

摘要

要成功地实施保护计划和物种管理策略，就必须对物种种群数量进行可靠的估算。在本研究中，我们的主要目的是描述一种组合方法，用于估计成年和次成年个体海豹N. kaiseri的种群规模时的检测概率（P）。凯塞里猪笼草被列为极度濒危物种，因为其栖息地高度零散，而且在繁殖期间其分布范围很小。我们确实确定了P在我们可以估计人口规模的研究中，我们在3月至4月的早晨，中午和下午的不同时间进行了视觉相遇调查，这很可能是当检测概率达到三年来的最高值时。Lorestan ts的观测可能性在傍晚最高，约为60％，在中午最低，约为46％，而早晨的发现概率约为50％（P值≤0.05）。我们对伊朗西南部的凯塞里猪笼草共调查了55个地点。洛雷斯坦new使用了大量的水生生境。洛尔斯坦new（成人和亚成人）的人口规模，按P估计至少为14709±247。但是，这些发现表明那里的真实人口规模并不大。我们必须采取协调一致的保护计划，例如圈养管理，作为综合港口保护工作的权宜之计，小规模地区的开塞利猪笼草种群可能会灭绝。
