种群规模和诱捕能力的估计为疫苗效力建模提供信息，并在长期的野生动物疫苗接种活动中进行适应性管理。我们提出了一个分析标记重捕数据从獾疫苗（卡介苗）在爱尔兰的研究。这项研究是有史以来最大规模（755平方公里）的标记-再捕获研究与这个物种。研究区域被划分为三个大致相等大小的区域，每个区域都有类似的调查和捕获工作。平均獾人口规模为671（SD：76）估计使用封闭的亚群模型（CSPM）的基础上，从捕捉会议的整个地区的数据，并与一个单独的乘法模型是一致的。根据相同数据计算的最小存活数量估计值平均比CSpM估计值小49-51%，但当可捕获性较低时，认为这些估计值存在严重负偏倚。人口密度来自CSPM的估计为0.82-1.06獾公里22，并与以前的报告大致一致的邻近地区。在整个群体中，估计平均可捕获性为每次34-35%。到第五次捕获时，79%的成年獾已经被标记过。多变量建模表明獾trappability取决于区域，季节和年龄组的显着差异。在种群中发现了更多的pupar-trap-wareed獾比陷阱快乐獾，但谨慎性与个体的性别，区域或捕获季节无关。现场诱捕效果可以显着不同的网站，季节，年龄或个性，因此监测诱捕性的建议作为适应性管理制度的一部分，在大规模的野生动物疫苗接种计划，以对抗偏见，提高效率。引文：Byrne AW，O 'Keeffe J，绿色S，Sleeman DP，Corner LAL等（2012）欧洲獾（Meles meles）的种群估计和可捕获性：对结核病管理的影响。PLoS ONE 7（12）：e50807. doi：10.1371/journal.pone.0050807
Estimates of population size and trappability inform vaccine efficacy modelling and are required for adaptive management during prolonged wildlife vaccination campaigns. We present an analysis of mark-recapture data from a badger vaccine (Bacille Calmette-Guerin) study in Ireland. This study is the largest scale (755 km 2) mark-recapture study ever undertaken with this species. The study area was divided into three approximately equal-sized zones, each with similar survey and capture effort. A mean badger population size of 671 (SD: 76) was estimated using a closed-subpopulation model (CSpM) based on data from capturing sessions of the entire area and was consistent with a separate multiplicative model. Minimum number alive estimates calculated from the same data were on average 49-51% smaller than the CSpM estimates, but these are considered severely negatively biased when trappability is low. Population densities derived from the CSpM estimates were 0.82-1.06 badgers km 22, and broadly consistent with previous reports for an adjacent area. Mean trappability was estimated to be 34-35% per session across the population. By the fifth capture session, 79% of the adult badgers caught had been marked previously. Multivariable modelling suggested significant differences in badger trappability depending on zone, season and age-class. There were more putatively trap-wary badgers identified in the population than trap-happy badgers, but wariness was not related to individual's sex, zone or season of capture. Live-trapping efficacy can vary significantly amongst sites, seasons, age, or personality, hence monitoring of trappability is recommended as part of an adaptive management regime during large-scale wildlife vaccination programs to counter biases and to improve efficiencies.
