对于许多分类单元来说,全球范围内非本地引入的新记录以接近指数的速度出现。我们对有关非本地爬虫的同行评审出版物进行了系统的审查,评估可用于评估未来入侵风险的信息库,产生836篇相关论文。文献的分类和地理范围也与全球所有已知入侵的已发布数据库进行了比较。我们发现了1,116种爬虫,其中95%出现在少于12项研究中。自2000年以来,几乎所有有关爬虫入侵生态学的文献都出现了,重点是青蛙(58%),特别是甘蔗蟾蜍(莱茵内拉码头)及其在澳大利亚的影响。虽然在海龟和蛇上发表的论文较少,与青蛙相比,研究了这两个群体中更多的物种。在每个Herpetofaunal组中,有少数经过充分研究的物种:R.marina,脉石,非洲爪狼,Trachemysscripta,博伊加·非罗利斯·萨格利斯。大多数研究(416篇论文;50%)都解决了影响,对贸易等方面的研究要少得多(2%)。除了澳大利亚(213项研究),大多数国家很少有关于非本地爬虫的特定地点的同行评审文献(平均每个已建立物种1.1篇论文)。其他例外是关岛,英国,中国,加州和法国,但即使是他们在既定物种中的出版物报道也不均匀。评估和优先考虑入侵物种的新方法,例如《外来分类群环境影响分类》,为风险评估提供了有用的框架,但需要强有力的物种水平研究。全球倡议,类似于全球两栖动物评估,使用这里确定的物种和分类群,需要在应用这些框架所需的广泛地理范围内获得信息水平。对模型物种的扩展研究可用于指示未被研究的分类单元的生产性研究重点。
For many taxa, new records of non-native introductions globally occur at a near exponential rate. We undertook a systematic
review of peer-reviewed publications on non-native herpetofauna, to assess the information base available for assessing risks of future invasions, resulting in 836 relevant papers. The taxonomic and geographic scope of the literature was also compared to a published database of all known invasions globally. We found 1,116 species of herpetofauna, 95% of which were present in fewer than 12 studies. Nearly all literature on the invasion ecology of herpetofauna has appeared since 2000, with a strong focus on
frogs (58%), particularly cane toads (Rhinella marina) and their impacts in Australia. While fewer papers have been published on turtles and snakes, proportionately more species from both these groups have been studied than for
frogs. Within each herpetofaunal group, there are a handful of well-studied species: R. marina, Lithobates catesbeianus, Xenopus laevis, Trachemys scripta, Boiga irregularis and Anolis sagrei. Most research (416 papers; 50%) has addressed impacts, with far fewer studies on aspects like trade (2%). Besides Australia (213 studies), most countries have little location-specific peer-reviewed literature on non-native herpetofauna (on average 1.1 papers per established species). Other exceptions were Guam, the UK, China, California and France, but even their publication coverage across established species was not even. New methods for assessing and prioritizing invasive species such as the Environmental Impact Classification for Alien Taxa provide useful frameworks for risk assessment, but require robust species-level studies. Global initiatives, similar to the Global Amphibian Assessment, using the species and taxonomic groups identified here, are needed to derive the level of information across broad geographic ranges required to apply these frameworks. Expansive studies on model species can be used to indicate productive research foci for understudied taxa.
