“…Climate change causes increases in temperatures of freshwater bodies worldwide (Liu et al., 2020), which can have pronounced negative effects on fish communities. At its most severe, increasing temperatures cause the extripation of cold‐adapted species (Stefani et al., 2020).…”

“…Changed river flows can also alter other abiotic variables. For example, decreased water levels can decrease dissolved oxygen concentrations and increase water temperature, and increased discharge from dams and terrestrial run‐off may lead to altered temperature regimes (Liu et al., 2018, 2020). These environmental changes influence the physiology of aquatic organisms and may thereby modify ecological processes such as dispersal (Jung et al., 2020; Le Roy & Seebacher, 2018), and community structure (Stefani et al., 2020).…”

The health of running freshwater systems depends to a large extent on flow rates, which can co‐vary with other environmental variables such as temperature. Water flow and temperature can influence oxidative status of individual animals, thereby impacting muscle function and locomotion. Consequently, ecologically important behaviours such as dispersal may be disrupted. Our aim was to determine whether the interactions between acclimation to flowing water (3 weeks at 0.06 m/s or still water), thermal acclimation (3 weeks at 18 and 28°C), and acute test temperatures (18–32°C) determine oxidative status, locomotor performance, and dispersal in mosquitofish (Gambusia holbrooki). We show that swimming capacity was greater in fish living in flowing water compared to those in still water, and that this difference was greater in warm acclimated fish. However, dispersal was not dependent on maximal locomotor capacities. Fish initiated dispersal to a greater extent when acclimated to flowing water and cool temperature, although there were interactions with acute test temperature. Dispersal speed was not affected by flow acclimation, but it was greater at cool test temperatures in cool acclimated fish, and vice versa for warm acclimated fish. Also, fish acclimated to flowing and cool water made a greater number of dispersal decisions. Oxidative damage to membranes and proteins did not change with flow or temperature treatments, but antioxidant capacities were greater in animals acclimated to flow and cool temperatures. Trait‐specific approaches used to assess fish responses to altered flow regimes typically consider a range of morphological and life‐history traits to characterise species and predict the impact of environmental change. Physiological traits and responses such as those we describe here can be a useful addition to life‐history traits in predicting the impact of environmental change on movement. Consideration of the impacts of physiological traits on dispersal can increase the efficacy of management and restoration projects.

“…Because nitrogen transport is associated with water temperature, this variable was also considered in CAS-LSM following the scheme of Van Vliet et al (2012). Anthropogenic heat discharge from thermoelectric power plants was also considered in CAS-LSM (Liu et al, 2019(Liu et al, , 2020, where the input data for the emitted heat came from Raptis and Pfister (2016).…”

Eco-hydrological processes play an important role in land-atmosphere interactions, and human activities including CO 2 emissions and land and water resource management have been shown to influence the climate at a local and global scale (Pielke & Avissar 1990; Solomon et al., 2007). Agricultural activities including water withdrawal and irrigation human water use (HWR) can significantly cool the surface, enhance evapotranspiration, and consume local water resources (Lobell et al., 2006; Zeng et al., 2017). Extraction and consumption of water resource is also complicated by groundwater lateral flow (GLF) from the surrounding areas that offsets the loss of locally stored water and hence affects the climate (Maxwell et al., 2007; Z.

Nitrogen (N) transport from land to rivers, estuaries, and coastal marine systems has been markedly altered by anthropogenic and climatic drivers over recent decades. In this study, a riverine N transport scheme considering anthropogenic N discharge and water regulation was incorporated into the Land Surface Model of the Chinese Academy of Sciences (CAS-LSM). Seven groups of simulations using the developed model at the global scale for the period of 1981-2010 were conducted to investigate the effects of anthropogenic disturbances and climate change on riverine dissolved inorganic nitrogen (DIN) transport. It was shown that fertilization and point source pollution have enhanced the DIN fluxes in rivers across the world, especially in western Europe and eastern China. The DIN exports were significantly reduced due to retention by reservoirs and the withdrawal of surface water and groundwater, with a retention efficiency of 50-70%. Climate variability and trends increased or decreased the riverine DIN fluxes depending on the specific hydroclimatic conditions. We further analyzed the contributions of climatic and anthropogenic changes to the riverine DIN changes in four major rivers. The riverine DIN exports in the Mississippi River Basin were affected primarily by fertilization, while the changes in DIN exports of the Danube were dominated by point source pollution and water regulation. The Yangtze River in China was seriously affected by both fertilization and point source pollution, and water regulation played a significant role in reducing DIN exports. Climate variability was the primary factor explaining the interannual variability of DIN exports. Plain Language Summary Nitrogen (N) transport from land to rivers, estuaries, and coastal marine systems has been markedly altered by anthropogenic and climatic drivers over recent decades. The enhanced N exports from land to oceans endanger the ecological environment and human health, which represents a global-scale challenge. In this study, we incorporated a riverine N transport scheme considering anthropogenic dissolved inorganic nitrogen (DIN) discharge and water regulation into the Land Surface Model of the Chinese Academy of Sciences (CAS-LSM) to illustrate how anthropogenic disturbances and climate change affect riverine DIN transport. It was shown that fertilization and point source pollution enhanced the DIN fluxes in rivers across the world, while water regulation played a role in reducing DIN exports. Climate variability and trends increased or decreased the riverine DIN fluxes depending on the specific hydroclimatic conditions, and climate variability was the primary factor explaining the interannual variability of DIN exports.
