气候变化、土地利用变化、污染和开发是物种数量变化趋势的主要驱动因素；然而，它们的相对重要性却备受争议。我们使用了中欧22个社区的1000多个当地人口时间序列的独特集合，这些社区横跨陆地、淡水和海洋领域，比较了1980年以来长期温度变化和其他环境驱动因素的影响。为了理清不同的驱动因素，我们将物种的种群趋势与物种和驱动因素的特定属性（如温度和栖息地偏好或污染耐受性）联系起来。我们发现温度变化对当地陆生物种丰度的影响是一致的。暖栖物种种群数量的增长大于冷栖物种种群数量的增长。相反，温度变化对水生物种丰度的影响是可变的。温度偏好的影响在陆地群落中比栖息地偏好的影响更为一致，这表明温度变化的影响在中欧许多陆地群落的丰度近期变化中已经变得广泛。
Climate change, land-use change, pollution and exploitation are among the main drivers of species' population trends; however, their relative importance is much debated. We used a unique collection of over 1,000 local population time series in 22 communities across terrestrial, freshwater and marine realms within central Europe to compare the impacts of long-term temperature change and other environmental drivers from 1980 onwards. To disentangle different drivers, we related species' population trends to species-and driver-specific attributes, such as temperature and habitat preference or pollution tolerance. We found a consistent impact of temperature change on the local abundances of terrestrial species. Populations of warm-dwelling species increased more than those of cold-dwelling species. In contrast, impacts of temperature change on aquatic species' abundances were variable. Effects of temperature preference were more consistent in terrestrial communities than effects of habitat preference, suggesting that the impacts of temperature change have become widespread for recent changes in abundance within many terrestrial communities of central Europe.
