Species‐specific ‘resistance’ to impacts, such as accelerated climate change, and ‘resilience’ (if pressures are released), have important implications for long‐term persistence. There have been some reports that species’ traits may be related to resistance and resilience. We sought to determine whether guild membership, ecological versatility or life‐history traits of woodland birds were related to species’ resistance and resilience in the face of high‐amplitude climatic fluctuations over two decades. There were four extensive survey programmes in temperate woodlands in Victoria, Australia, spanning the longest, most intense drought on record in the region (Big Dry: 1996–2010), a short, intense wet period (Big Wet: 2010–2012) and a return to very dry conditions (post‐Big Wet: 2012–2016). We used species‐specific reporting rates (RRs) to identify species having low resistance to the Big Dry, high resilience (recovery) during the Big Wet and low resistance over the whole survey period (1996–2016). Species falling into these three groups were compared with species not showing those responses, and the contrasting groups evaluated for systematic differences in ecological and life‐history traits. Neither ecological nor life‐history traits accounted for much variation in the three contrasts, suggesting that Big Dry‐ and overall‐resistant species and Big Wet‐resilient species were not coherent subsets of the terrestrial avifaunas. Given that species’ traits were not related to vulnerability or to immunity from climatic pressures, we probably need to concentrate on species directly rather than groups defined by common life‐history or ecological traits. Moreover, it almost certainly will be more useful to focus conservation management on reducing pervasive, manageable pressures (e.g. natural resource extraction, land‐use change, reductions of greenhouse gas emissions), which is likely to provide assemblage‐wide benefits for birds and other taxa.

生态和生活史特征对鸟类对高振幅气候波动的脆弱性影响不大

特定物种对影响的“抵抗力”，例如加速的气候变化和“适应力”（如果释放压力），对长期持久性具有重要意义。有报道说，物种的性状可能与抗性和复原力有关。我们试图确定面对二十多年的高幅气候波动，林地鸟类的行会成员资格，生态多样性或生活史特征是否与物种的抵抗力和复原力有关。在澳大利亚维多利亚州的温带林地中，有四个广泛的调查项目，涵盖了该地区有记录以来最长，最强烈的干旱（大干旱：1996–2010），短暂而强烈的湿润时期（大潮湿：2010–2012）和恢复到非常干燥的条件（大湿后：2012-2016年）。我们使用特定物种的报告率（RRs）来识别对大干旱抵抗力低，在大潮湿时期具有高复原力（恢复）且在整个调查期间（1996-2016）低抵抗力的物种。将属于这三类的物种与未表现出这些响应的物种进行比较，对比组评估了生态和生活史特征的系统差异。在这三个对比中，生态特征和生活史特征都没有引起很大的差异，这表明，大的抗旱和总体抗性物种以及大的抗湿性物种不是陆地鸟类的连贯子集。鉴于物种的特征与脆弱性或不受气候压力的影响无关，我们可能需要直接关注物种，而不是根据共同的生活史或生态特征定义的群体。此外，几乎可以肯定的是，将保护管理的重点放在减少普遍的，可控的压力（例如自然资源开采，土地用途变化，减少温室气体排放）上，这很可能为鸟类和其他动物提供整体利益。分类单元。
