Abstract Reducing the rate of species extinctions is one of the great challenges of our time. Understanding patterns in the distribution and frequency of both threatened species and the threatening processes affecting them improves our ability to mitigate threats and prioritize management actions. In this quantitative synthesis of processes threatening Australian at-risk fauna, we find that species are impacted by a median of six threats (range 1–19), though there is considerable variation in numbers of threats among major taxonomic groups. Invasive species, habitat loss, biological resource use, natural systems modification and climate change are the processes most commonly affecting Australian threatened species. We identified an uneven distribution of research knowledge among species, with half of the total number of species-specific peer-reviewed scientific publications associated with only 11 threatened species (2.7%). Furthermore, the number of threats associated with each species was correlated with the research effort for that species, and research effort was correlated with body mass. Hence, there appears to be a research bias towards larger-bodied species, and certain charismatic species, that could result in inferences biased towards these favored species. However, after accounting for these effects we found that for birds, amphibians, reptiles and marine mammals body mass is positively correlated with the number of threats associated with each species. Many threats also co-occur, indicating that threat syndromes may be common.

危及澳大利亚濒危动物群的威胁

摘要 降低物种灭绝的速度是我们这个时代面临的巨大挑战之一。了解受威胁物种的分布和频率模式以及影响它们的威胁过程,可以提高我们减轻威胁和确定管理行动优先级的能力。在这个威胁澳大利亚濒危动物群的过程的定量综合中,我们发现物种受到六种威胁(范围 1-19)的影响,尽管主要分类群之间的威胁数量存在相当大的差异。入侵物种、栖息地丧失、生物资源利用、自然系统改造和气候变化是最常影响澳大利亚受威胁物种的过程。我们发现物种之间的研究知识分布不均,特定物种的同行评审科学出版物总数的一半仅与 11 种受威胁物种有关(2.7%)。此外,与每个物种相关的威胁数量与该物种的研究工作相关,而研究工作与体重相关。因此,似乎对体型较大的物种和某些有魅力的物种存在研究偏见,这可能导致推论偏向于这些受青睐的物种。然而,在考虑到这些影响后,我们发现鸟类、两栖动物、爬行动物和海洋哺乳动物的体重与每个物种相关的威胁数量呈正相关。许多威胁也同时发生,这表明威胁综合症可能很常见。与每个物种相关的威胁数量与该物种的研究工作相关,而研究工作与体重相关。因此,似乎对体型较大的物种和某些有魅力的物种存在研究偏见,这可能导致推论偏向于这些受青睐的物种。然而,在考虑到这些影响后,我们发现对于鸟类、两栖动物、爬行动物和海洋哺乳动物,体重与每个物种相关的威胁数量呈正相关。许多威胁也同时发生,这表明威胁综合症可能很常见。与每个物种相关的威胁数量与该物种的研究工作相关,而研究工作与体重相关。因此,似乎对体型较大的物种和某些有魅力的物种存在研究偏见,这可能导致推论偏向于这些受青睐的物种。然而,在考虑到这些影响后,我们发现鸟类、两栖动物、爬行动物和海洋哺乳动物的体重与每个物种相关的威胁数量呈正相关。许多威胁也同时发生,这表明威胁综合症可能很常见。和某些有魅力的物种,这可能导致推论偏向于这些受青睐的物种。然而,在考虑到这些影响后,我们发现鸟类、两栖动物、爬行动物和海洋哺乳动物的体重与每个物种相关的威胁数量呈正相关。许多威胁也同时发生,这表明威胁综合症可能很常见。和某些有魅力的物种,这可能导致推论偏向于这些受青睐的物种。然而,在考虑到这些影响后,我们发现鸟类、两栖动物、爬行动物和海洋哺乳动物的体重与每个物种相关的威胁数量呈正相关。许多威胁也同时发生,这表明威胁综合症可能很常见。
