The synchrony of population dynamics in space has important implications for ecological processes, for example affecting the spread of diseases, spatial distributions and risk of extinction. Here, we studied the relationship between spatial scaling in population dynamics and species position along the slow-fast continuum of life history variation. Specifically, we explored how generation time, growth rate and mortality rate predicted the spatial scaling of abundance and yearly changes in abundance of eight marine fish species. Our results show that population dynamics of species' with 'slow' life histories are synchronised over greater distances than those of species with 'fast' life histories. These findings provide evidence for a relationship between the position of the species along the life history continuum and population dynamics in space, showing that the spatial distribution of abundance may be related to life history characteristics.
种群动态在空间上的同步性对生态过程有重要影响,例如影响疾病的传播、空间分布和灭绝风险。在这里,我们研究了种群动态的空间尺度与物种在生命史变异的慢-快连续体上的位置之间的关系。具体来说,我们探讨了世代时间、增长率和死亡率如何预测 8 种海洋鱼类的丰度和丰度年际变化的空间尺度。我们的结果表明,“慢”生命史物种的种群动态在更大的距离上是同步的,而“快”生命史物种的种群动态则不是。这些发现为物种在生命史连续体上的位置与空间上的种群动态之间的关系提供了证据,表明丰度的空间分布可能与生命史特征有关。
