栖息地的丧失是生物多样性丧失的一个重要驱动因素，导致适宜土地覆盖的小块、孤立的斑块破碎化。这降低了景观对个体移动的渗透性，并降低了集合种群持续存在的可能性。因此，量化功能连接性，焦点物种在资源斑块之间移动的能力，对于保护管理至关重要。有大量的证据支持基于“人口同步”的技术-不同长期监测点之间的年度人口增长率时间序列的相关程度，以提供功能连接的测量。然而，同步的种群动态不仅是由站点之间的个体移动驱动的，而且还必须考虑到共享的环境条件。在这里，我们使用物种调查数据从四十多年来调查的平均水平和时间趋势的人口同步性为58英国鸟类和蝴蝶物种。我们首先表明，人口同步性显着相关的同步性在一些季节性气候变量。一旦我们考虑到时空气候模式，我们发现蝴蝶的同步性在1985年至2000年间下降了71%，但近年来增加了64%。鸟类的同步性在1999年至2005年期间有所下降，之后似乎有所恢复，但大多数物种（74%）的同步性没有显着的整体变化。我们提出的指标提供了一个“物种的眼睛视图”的功能连接使用广泛可用的丰度数据。制定这种可每年更新的功能连通性指标，对于在日益加剧的环境变化下提高土地管理战略的有效性至关重要。
Habitat loss is a significant driver of biodiversity loss, causing fragmentation into small, isolated patches of suitable land cover. This reduces the permeability of landscapes to the movement of individuals and reduces the likelihood of metapopulation persistence. Quantifying functional connectivity, the ability of a focal species to move between resource patches, is therefore essential for conservation management. There is substantial evidence supporting a technique based on ‘population synchrony’- the degree of correlation in time-series of annual population growth rates between different long-term monitoring sites, to provide a measure of functional connectivity. However, synchronised population dynamics are not only driven by the movement of individuals between sites, but also shared environmental conditions which must be accounted for. Here, we use species survey data from over four decades to investigate average levels and temporal trends in population synchrony for 58 British bird and butterfly species. We first show that population synchrony is significantly associated with synchrony in some seasonal climatic variables. Once we accounted for spatiotemporal climatic patterns, we found that synchrony in butterflies declined over time by 71% between 1985 and 2000 but increased by 64% in recent years. Synchrony in birds showed some decline between 1999 and 2005, after which there appears to being recovery, however most species (74%) show no significant overall change in synchrony. Our proposed indicator provides a ‘species-eye-view’ of functional connectivity using widely available abundance data. Developing such indicators of functional connectivity, which can be updated annually, is crucial to improve the effectiveness of land management strategies for conservation under increasing environmental change.
