摘要

尽管生态位的长期动态评估可以为研究物种对环境变化的响应提供重要信息,但在生态学中这是一个研究较少的话题。本文以意大利北部71种常见种鸟为研究对象,分析了1992 - 2017年的生态位变化及其与种群趋势和物种性状的关系。我们(i)量化了环境空间中已实现的格林内尔生态位,(ii)比较了生态位宽度和质心的变化,(iii)通过等效性和相似性检验了生态位的差异和保守性,(iv)计算了生态位时间重叠、扩展和未填充指数,(v)研究了它们与种群变化和物种性状的关系。结果显示,32%的物种存在生态位差异(等效性测试),但三分之二的物种没有得到相似性测试的支持。我们发现了一种将生态位质心向更温暖的热条件调整的总体趋势。种群增加与生态位扩展呈正相关,与生态位重叠呈负相关,但在显著性阈值范围内。我们发现适度的证据表明,生态位变化与物种特征之间存在非随机关联,特别是在体型、窝卵数、每年产卵数、居住景观类型和迁徙策略之间。我们鼓励将种群长期趋势和生态位变化与物种特征信息相关联的研究,并特别关注单物种和多物种水平上的因果关系。

New Evidence on the Linkage of Population Trends and Species Traits to Long-Term Niche Changes
Despite the assessment of long-term niche dynamics could provide crucial information for investigating species responses to environmental changes, it is a poorly investigated topic in ecology. Here, we present a case study of multi-species niche analysis for 71 common breeding birds in Northern Italy, exploring long-term niche changes from 1992 to 2017 and their relationship with both population trends and species traits. We (i) quantified the realized Grinnellian niche in the environmental space, (ii) compared variations in niche breadth and centroid, (iii) tested niche divergence and conservatism through equivalency and similarity tests, (iv) calculated niche temporal overlap, expansion and unfilling indices, and (v) investigated their association with both population changes and species traits. Results supported niche divergence (equivalency test) for 32% of species, although two-thirds were not supported by the similarity test. We detected a general tendency to adjust the niche centroids towards warmer thermal conditions. Increasing populations were positively correlated with niche expansion, while negatively correlated with niche overlap, albeit at the limit of the significance threshold. We found moderate evidence for a non-random association between niche changes and species traits, especially for body size, clutch size, number of broods per year, inhabited landscape type, and migration strategy. We encourage studies correlating long-term population trends and niche changes with species traits’ information and a specific focus on cause-effect relationship at both the single and multiple-species level.
