天气可以解释昆虫生物量的年际变化，但不能解释昆虫生物量的时间性下降

Müller等人重新分析了1989年至2016年间德国昆虫生物量时间变化的已发表数据，重点是模拟天气条件对昆虫生物量的影响。这些利用外部验证数据集进行的升级分析很好地证明了气候条件对每年昆虫生物量的强烈影响。然而，Müller 等人认为天气条件的时间变化解释了昆虫生物量的大部分时间变化，这一结论被夸大了。我们认为，他们的方法不适合得出这样的结论，因为存在遗漏变量偏差。我们重新进行了 Müller 等人的分析，但考虑到了因缺失驱动因素而导致的昆虫生物量的剩余时间趋势。我们的结果表明，Müller 等人的主要结论是错误的：天气条件无法解释昆虫生物量在时间上的显著下降。我们的评论回顾说，不考虑缺失的预测因子很可能会产生偏差很大的结果，尤其是当缺失的预测因子与可用的预测因子相关时，而大多数与全球变化相关的人为压力很可能就是这种情况。这凸显了估算全球变化因素在推动观察到的生物多样性变化方面的相对重要性所面临的艰巨挑战。

期刊介绍： To publish papers of the highest scientific quality within the general area of insect (and other arthropods) conservation and diversity covering topics ranging from ecological theory to practical management. Papers are invited on the following topics: Conservation genetics; Extinction debt; Long-term conservation planning and implementation; Global implications of local or national conservation actions; Management responses of species and communities; Captive breeding programs; Comparisons of restored and natural habitats; Biogeography; Global biodiversity; Metapopulation dynamics; Climate change: impacts on distributions and range; Invasive species: impacts and control; Effects of pollution; Genetic threats to diversity by introgression; Effects of fragmentation on diversity and distribution; Impact of agricultural and forestry practices on biodiversity; Enhancing urban environments for diversity and protection; Biodiversity action plans: can we scale up from insects?; Effectiveness and choice of indicator species; Soil biodiversity and interactions with above-ground biodiversity; Ecological interactions at local levels; Ecological and evolutionary factors influencing diversity and local, regional and global scales; Sustainable livelihoods and training on the ground; Integrating science and policy.
