Range shifts are a key mechanism that species employ in response to climate change. Increasing global temperatures are driving species redistributions to cooler areas along three main spatial axes: increasing latitudes, altitudes and water depths. Climate‐mediated range shift theory focuses on temperature as the primary ecological driver, but global change alters other environmental factors as well, and these rarely work in isolation. Ecosystems are often characterized as mosaics of overlapping environmental stressors, resulting in temporal and spatial heterogeneity which differs between stable, low complexity mosaics (e.g. open ocean) and highly variable, highly complex mosaic environments (e.g. estuaries). We propose a multistressor mosaic of climate‐mediated species range shift across abiotic environmental gradients, typical for mobile species (e.g. fish) in variable coastal environments. We conceptualize how climate‐driven changes in salinity, temperature, dissolved oxygen and pH can drive redistribution of estuarine species in a future world. Non‐thermal drivers are a critical component of species range shifts and when not considered, underestimate the impact of global change on species populations and ecosystem services.

在未来气候下，河口环境中的物种沿着多应力因子镶嵌体发生变化

范围变化是物种应对气候变化所采用的关键机制。全球温度升高正在推动物种沿着三个主要空间轴重新分布到较凉爽的区域：纬度，海拔和水深的增加。气候介导的距离变化理论把温度作为主要的生态驱动力，但全球变化也改变了其他环境因素，而这些因素很少孤立地起作用。生态系统的特征通常是重叠的环境压力因子马赛克，导致时间和空间异质性，在稳定，低复杂度的马赛克（例如大洋）和高度变化，高度复杂的马赛克环境（例如河口）之间有所不同。我们提出了跨非生物环境梯度的气候介导物种范围变化的多应激动物镶嵌，在变化的沿海环境中通常用于流动物种（例如鱼类）。我们将盐度，温度，溶解氧和pH值的气候驱动变化如何驱动未来世界中河口物种的重新分配概念化。非热驱动因素是物种范围变化的重要组成部分，如果不加以考虑，则低估了全球变化对物种种群和生态系统服务的影响。
