Freshwater fish face a variety of spatiotemporal thermal challenges throughout their life. On a broad scale, temperature is an important driver of physiological, behavioural and ecological patterns and ultimately affects populations and overall distribution. These broad patterns are partly underpinned by the small-scale local effects of temperature on individuals within the population. Climate change is increasing the range of daily thermal variation in most freshwater ecosystems, altering behaviour and performance of resident fishes. The aim of this review is understanding how daily thermal variation in temperate rivers affects individual fish physiology, behaviour and overall performance. The following are highlighted in this study: (a) the physical characteristics of rivers that can either buffer or exacerbate thermal variability, (b) the effects of thermal variability on growth and metabolism, (c) the approaches for quantifying thermal variation and thermal stress and (d) how fish may acclimatize or adapt to our changing climate.

温带淡水生态系统热变化的生理起伏

淡水鱼在其一生中面临着各种时空热挑战。从广义上讲，温度是生理、行为和生态模式的重要驱动因素，并最终影响种群和整体分布。这些广泛的模式部分受到温度对人群中个体的小规模局部影响的支持。气候变化增加了大多数淡水生态系统中每日热变化的范围，改变了当地鱼类的行为和表现。本综述的目的是了解温带河流中的日常热变化如何影响个体鱼类的生理、行为和整体表现。本研究强调以下几点：(a) 河流的物理特征可以缓冲或加剧热变化，
