识别温度对物种种群丰富度的影响模式，有助于制定一个总体框架，以预测气候变化在不同社区和领域的后果。我们使用了来自中欧陆地、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体中物种丰度的影响。我们询问不同季节的温度与群落中物种的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、身体大小和寿命)是否解释了温度与物种丰度关系的种间差异。我们发现，平均而言，温暖的冬季温度与陆地群落(地甲虫、蜘蛛和鸟类)的数量较多有关，但并不总是与水生群落(淡水和海洋无脊椎动物和鱼类)的数量有关。地理范围大、体型较大、寿命较长的物种的丰富度与温度的相关性较小。我们的结果表明，总的来说，气候变化可能对中欧许多陆地群落中的物种丰富度产生积极影响，而在水生群落中，这种影响则难以预测。
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.
