In Focus: Vindstad, O. P. L., Jepsen, J. U., Yoccoz, N. G., Bjørnstad, O. N., Mesquita, M. d. S., & Ims, R. A. (2019). Spatial synchrony in sub-arctic geometrid moth outbreaks reflects dispersal in larval and adult life cycle stages. Journal of Animal Ecology, 88, 1134-1145. https://doi.org/10.1111/1365-2656.12959. Spatial synchrony of population dynamics is a common phenomenon, but the understanding of underlying mechanisms is supported more by theoretical than empirical studies. Vindstad et al. (2019) use a 19-year dataset on two moth species to disentangle the effects of different drivers of dispersal on the synchrony of populations. They show that geographic distance, species dispersal capabilities, a dispersal barrier and the prevailing wind direction are all factors that influence spatial synchrony. With current climate change and ongoing habitat fragmentation, understanding how dispersal influences spatial synchrony of population fluctuations, and the effect on population viability, is essential to predict future impacts on our ecosystems.
文斯塔德、Jepsen、约科兹、比约恩斯塔德、梅斯基塔和伊姆斯（2019 年）。亚北极尺蠖蛾类幼虫和成虫生活史阶段的扩散解释了亚北极地区尺蠖蛾类爆发的空间同步性。动物生态学杂志，88，1134-1145。doi: 10.1111/1365-2656.12959. 种群动态的空间同步性是一种常见现象，但对潜在机制的理解更多地依赖于理论而不是实证研究。文斯塔德等人（2019 年）使用了 19 年的两种蛾类数据来区分不同扩散驱动因素对种群同步性的影响。他们表明，地理距离、物种扩散能力、扩散障碍和盛行风向都是影响空间同步性的因素。随着当前的气候变化和正在进行的栖息地破碎化，了解扩散如何影响种群波动的空间同步性，以及对种群生存力的影响，对于预测未来对我们生态系统的影响至关重要。
