Globalisation of the live pet trade facilitates major pathways for the transport and introduction of invasive alien species across longer distances and at higher frequencies than previously possible. Moreover, the unsustainable trade of species is a major driver for the over-exploitation of wild populations. Australia minimises the biosecurity and conservation risk of the international pet trade by implementing highly stringent regulations on the live import and keeping of alien pets beyond its international CITES obligations. However, the public desire to possess prohibited alien pets has never been quantified and represents a number of species that could be acquired illegally or legally under different future legislative conditions. As such, highly desirable species represent an ongoing conservation threat and biosecurity risk via the pet-release invasion pathway. We aimed to characterise the Australian desire for illegal alien pets and investigate potential sources of external information that can be utilised to predict future desire. Using public live import enquiry records from the Australian Commonwealth Department of Agriculture, Water and the Environment as a proxy for alien pet desire, we tested for differences in the proportion of species with threatened listings and records of invasions, after accounting for taxonomy. Additionally, we used a United States of America (U.S.) live imports dataset to infer pet demand in another Western market with less stringent regulations and determined whether species highly desired in Australia had higher U.S. trade demand than would be expected by chance. The Australian public desire for alien pets is heavily and significantly biased towards species threatened with extinction, species popular in the U.S. trade and species with a history of successful invasions. Not only does this indicate the potential impacts of pet desire on invasion risk and the conservation of threatened species, but we also highlight the potential role of the U.S. trade as an effective predictor for Australian desire. Our research emphasises the value of novel datasets in building predictive capacity for improved biosecurity awareness.

澳大利亚的外来宠物的愿望清单:所需外来和非法宠物物种的生物安全性和保护意义

活宠物贸易的全球化为跨界运输和引入外来入侵物种提供了较以往更大的主要途径。此外,物种的不可持续贸易是野生种群过度开发的主要原因。澳大利亚通过实施对活体进口和饲养外来宠物的严格规定,将国际宠物贸易的生物安全性和保护风险降到最低,这超出了其国际CITES义务。但是,公众对于拥有被禁止的外来宠物的渴望从未被量化,它代表了在不同的未来立法条件下可以非法或合法获得的许多物种。因此,高度可取的物种通过宠物释放入侵途径表现出持续的保护威胁和生物安全风险。我们旨在表征澳大利亚人对非法外来宠物的需求,并调查可用于预测未来需求的外部信息的潜在来源。我们使用澳大利亚联邦农业,水和环境部的公开进口实时查询记录作为外来宠物欲望的替代物,在考虑了分类法之后,我们测试了濒危物种和入侵记录的物种比例差异。此外,我们使用美国活体进口数据集推断法规要求不那么严格的另一个西方市场的宠物需求,并确定了澳大利亚高度需求的物种是否具有更高的美国 贸易需求超出了偶然的预期。澳大利亚公众对外来宠物的渴望在很大程度上严重威胁了濒临灭绝的物种,在美国贸易中流行的物种以及具有成功入侵史的物种。这不仅表明宠物需求对入侵风险和受威胁物种的保护的潜在影响,而且我们还强调了美国贸易作为澳大利亚需求的有效预测因素的潜在作用。我们的研究强调新型数据集在建立预测能力以提高生物安全意识方面的价值。这不仅表明宠物需求对入侵风险和受威胁物种的保护的潜在影响,而且我们还强调了美国贸易作为澳大利亚需求的有效预测因素的潜在作用。我们的研究强调新型数据集在建立预测能力以提高生物安全意识方面的价值。这不仅表明宠物需求对入侵风险和受威胁物种的保护的潜在影响,而且我们还强调了美国贸易作为澳大利亚需求的有效预测因素的潜在作用。我们的研究强调新型数据集在增强生物安全意识的预测能力中的价值。
