澳大利亚的无捕食者保护区(安全避难所)成功保护了濒危哺乳动物,但研究表明这些设施对两栖动物、爬行动物、鸟类和无脊椎动物的保护作用并不理想。[1]研究人员检查了123个受威胁物种的已知分布范围,发现目前仅有2个物种——大沙漠蜥蜴和西部沼泽龟——的种群得到现有避难所的保护。[1]
鉴于现有保护区的局限性,研究人员已识别出东澳大利亚的优先建设地点,建议建立专门针对非哺乳动物物种的新避难所。[1]这些优先地点包括维多利亚州阿尔卑斯山、新南威尔士州的雪山和塔斯马尼亚中部高地。[1]新避难所需要采用不同的隔离措施和地形特征,以应对多样化的生态威胁。[1]以绿色和金色钟蛙为例,这个物种同时受到致命真菌和入侵鱼类(蚊子鱼)的双重威胁。[1]
Australia's predator-free sanctuaries have proven effective at protecting endangered mammals, yet research indicates these refuges provide inadequate protection for amphibians, reptiles, birds, and invertebrates.[1] Currently, only two species—the great desert skink and western swamp tortoise—maintain populations within existing sanctuaries.[1]
Researchers examined the known distribution ranges of 123 threatened species across these four animal groups to assess sanctuary effectiveness.[1] The study identified priority locations in eastern Australia for establishing new refuges specifically designed for non-mammalian species, incorporating different isolation measures and terrain features suited to the diverse threats these animals face.[1] Recommended sites include the Victorian Alps, the Snowy Mountains in New South Wales, and the central highlands of Tasmania.[1]
The green and golden bell frog illustrates the complexity of protecting vulnerable wildlife, simultaneously facing threats from a deadly fungus and invasive mosquitofish, demonstrating why existing sanctuaries may not adequately address the multifaceted challenges confronting non-mammalian species.[1]
