Environmental variation is a ubiquitous component of individual, population and community processes in the natural world. Here, we review the consequences of spatio-temporally autocorrelated (coloured) environmental variation for ecological and evolutionary population dynamics. In single-species population models, environmental reddening increases (decreases) the amplitude of fluctuations in undercompensatory (overcompensatory) populations. This general result is also found in structurally more complex models (e.g. with space or species interactions). Environmental autocorrelation will also influence evolutionary dynamics as the changing environment is filtered through ecological dynamics. In the context of long-term environmental change, it becomes crucial to understand the potential impacts of different regimes of environmental variation at different scales of organization, from genes to species to communities.
环境变异是自然界中个体、种群和群落过程普遍存在的一个组成部分。在此，我们综述了时空自相关（有色）环境变异对生态和进化种群动态的影响。在单物种种群模型中，环境变红增加（减少）了欠补偿（过补偿）种群波动的幅度。在结构更复杂的模型（如具有空间或物种相互作用的模型）中也发现了这一普遍结果。环境自相关也将影响进化动态，因为变化的环境是通过生态动态进行筛选的。在长期环境变化的背景下，了解不同尺度组织（从基因到物种再到群落）下不同环境变异模式的潜在影响变得至关重要。
