物候学的进步和地理范围的极移和上移是物种对气候变化做出反应的有据可查的迹象。更深入地了解生态上不同的物种群体的这种反应将有助于评估整个生态系统的未来后果。与气候变化有关的一个研究较少的模式是，与适应寒冷的物种相比，适应温暖的物种的丰度增加。为了比较最近的气候变化如何影响不同分类群的物种丰度，我们分析了长期的当地种群趋势，并将其与物种温度生态位联系起来，从地理分布中推断。我们使用了在中欧不同地区（主要是德国）收集的蝙蝠、鸟类、蝴蝶、地面甲虫、跳虫和干旱草原植物的种群数据集。我们发现，温度生态位是正相关的一些分类群体（鸟类，蝴蝶，地面甲虫）的长期人口趋势，但不太重要的其他（蝙蝠，跳虫，草原植物）。这种温度生态位的重要性的变化表明，一些种群受到气候变化的影响大于其他种群，这可能是由于物种属性的差异，如世代时间和微生境偏好。我们的研究结果表明，有关物种的温度生态位的人口趋势是一个有用的方法来量化气候变化对当地人口丰度的影响。我们表明，这种广泛适用的方法是特别适合比较跨系统的分析，以确定哪些类型的生物，在栖息地，对气候变化的反应最。(C)2015爱思唯尔有限公司版权所有。
Advances in phenology and pole- and up-ward shifts in geographic ranges are well-documented signs that species are responding to climate change. A deeper understanding of such responses across ecologically different species groups will help to assess future consequences for entire ecosystems. A less well-studied pattern linked with climate change is increases in abundances of warm-adapted species compared with cold-adapted species. To compare how recent climate change has affected the abundances of species across different taxonomic groups, we analyzed long-term local population trends and related them to the species temperature niche, as inferred from geographic distributions. We used population data sets collected in different regions of Central Europe, primarily Germany, for bats, birds, butterflies, ground beetles, springtails and dry grassland plants. We found that temperature niche was positively associated with long-term population trends in some of the taxonomic groups (birds, butterflies, ground beetles) but was less important in others (bats, springtails, and grassland plants). This variation in the importance of temperature niche suggested that some populations have been affected more than others by climate change, which may be explained by differences in species attributes, such as generation time and microhabitat preference. Our findings indicate that relating temperature niches of species to population trends is a useful method to quantify the impact of climate change on local population abundances. We show that this widely applicable approach is particularly suited for comparative cross-system analyses to identify which types of organisms, in which habitats, are responding the most to climate change.
