摘要

摘要澳大利亚的野猪数量之前已经被估计过了，这是一个有争议的话题。本研究旨在更新先前对澳大利亚野猪丰度的估计(1350万只，95% CI: 350万至2350万只)。20世纪70年代、80年代、90年代、2000年代和2010年代的丰度估计是根据已发表的文献整理的。中间几十年的平均丰度用比值法估计。野猪的平均丰度从20世纪80年代的440万头(95% CI: 240万至630万)到90年代的300万头(95% CI: 230万至370万)，再到21世纪头十年的320万头(95% CI: 240万至400万)不等。所有142项研究的平均密度为1.03头猪km-2。在20世纪80年代到21世纪初，澳大利亚野猪的平均丰度比之前估计的要低得多，也更精确，因此科学家和管理者应该更新他们对丰度估计的使用。密度估计值高于和低于传染性外来疾病建立的阈值宿主密度估计值。

How many feral pigs in Australia? An update

Abstract. The abundance of feral pigs in Australia has been estimated previously and been a topic of some debate. This study aims to update a previous estimate of abundance (13.5 million, 95% CI: 3.5 million to 23.5 million) of feral pigs in Australia. Abundance estimates for the 1970s, 1980s, 1990s, 2000s and 2010s were collated from published literature. Mean abundances in the middle decades were estimated using the ratio method. The average abundance of feral pigs varied from 4.4 million (95% CI: 2.4 million to 6.3 million) in the 1980s, to 3.0 million (95% CI: 2.3 million to 3.7 million) in the 1990s, to 3.2 million (95% CI: 2.4 million to 4.0 million) in the 2000s. Mean density across all 142 studies was 1.03 pigs km–2. The average abundance of feral pigs in Australia during the 1980s to 2000s was much lower and more precise than estimated previously, so scientists and managers should update their use of abundance estimates. Density estimates are above, and below, estimates of threshold host densities for infectious exotic disease establishment.

期刊介绍： Australian Journal of Zoology is an international journal publishing contributions on evolutionary, molecular and comparative zoology. The journal focuses on Australasian fauna but also includes high-quality research from any region that has broader practical or theoretical relevance or that demonstrates a conceptual advance to any aspect of zoology. Subject areas include, but are not limited to: anatomy, physiology, molecular biology, genetics, reproductive biology, developmental biology, parasitology, morphology, behaviour, ecology, zoogeography, systematics and evolution. Australian Journal of Zoology is a valuable resource for professional zoologists, research scientists, resource managers, environmental consultants, students and amateurs interested in any aspect of the scientific study of animals. Australian Journal of Zoology is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
