Spatial correlograms showing the autocorrelation coefficient (r) as a function of distance, 95% confidence intervals surrounding the null hypothesis of a random distribution of feral pigs in north Queensland

Feral pigs occur throughout tropical far north Queensland, Australia and are a significant threat to biodiversity and World Heritage values, agriculture, and are a vector of infectious diseases. One of the constraints on long-lasting, local eradication of feral pigs is the process of reinvasion into recently controlled areas. This study examined the population genetic structure of feral pigs in far north Queensland to identify the extent of movement and the scale at which demographically independent management units (MU) exist. Genetic analysis of 328 feral pigs from the Innisfail to Tully region of tropical Queensland was undertaken. Seven microsatellite loci were screened and Bayesian clustering methods used to infer population clusters. Sequence variation at the mitochondrial DNA control region was examined to identify pig breed. The graphs depict an autocorrelation coefficient (r) as a function of distance: (A) 5 km Distance Class. (B) 10 km Distance Class. (C) 20 km Distance Class.

野生猪种广泛分布于澳大利亚热带远北昆士兰州，其对生物多样性、世界遗产价值、农业构成重大威胁，且为传染病传播的媒介。长期、局部根除野生猪种的一大制约因素是近期已控制的区域内再次入侵的过程。本研究旨在考察远北昆士兰州野生猪种的种群遗传结构，以确定其移动范围及独立管理单元（MU）在人口统计学上的规模。对来自热带昆士兰州Innisfail至Tully区域的328头野生猪进行了遗传分析。筛选了七个微卫星位点，并使用贝叶斯聚类方法推断种群聚类。对线粒体DNA控制区域的序列变异进行了考察，以确定猪种。图表展示了自相关系数（r）随距离的变化：（A）5公里距离类别。（B）10公里距离类别。（C）20公里距离类别。
