Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and annual abundances of species in a community, and whether species attributes (temperature range of distribution, range size, habitat breadth, dispersal ability, body size, and lifespan) explained interspecific variation in the relationship between temperature and abundance. We found that, on average, warmer winter temperatures were associated with greater abundances in terrestrial communities (ground beetles, spiders, and birds) but not always in aquatic communities (freshwater and marine invertebrates and fish). The abundances of species with large geographical ranges, larger body sizes, and longer lifespans tended to be less related to temperature. Our results suggest that climate change may have, in general, positive effects on species' abundances within many terrestrial communities in central Europe while the effects are less predictable in aquatic communities.
识别温度对物种种群丰度影响的模式，有助于构建一个通用框架，用于预测气候变化对不同群落和领域的影响。我们利用中欧陆地、淡水和海洋物种群落的长期种群时间序列数据，比较了温度对广泛分类群丰度的影响。我们探讨了不同季节的温度与群落中物种年丰度之间是否存在平均关系，以及物种属性（分布温度范围、分布范围大小、栖息地宽度、扩散能力、体型和寿命）是否能解释温度与丰度关系中的种间差异。我们发现，总体而言，冬季气温升高与陆地群落（步甲、蜘蛛和鸟类）的丰度增加有关，但在水生群落（淡水和海洋无脊椎动物及鱼类）中并非总是如此。地理分布范围大、体型大、寿命长的物种的丰度与温度的相关性往往较小。我们的结果表明，总体而言，气候变化可能对中欧许多陆地群落中的物种丰度产生积极影响，而对水生群落的影响则较难预测。
