“…In addition, recent studies have found that the winter streamflow increased much faster than the annual streamflow in the permafrost-dominated upper river basins of Siberia (Panyushkina et al, 2021). Liu et al (2022) further revealed uneven increases in streamflow during early, mid-and late winter across four large Arctic river basins. Winter streamflow in permafrost-dominated river basins is primarily recharged by the groundwater (Wang et al, 2021a;Liu et al, 2022), therefore, recent increases in winter streamflow likely reflect permafrost degradation under climate warming.…”

“…In contrast, during the warm non-winter period, streamflow in only two of five river basins show increasing trends with a significance level of p < 0.05. As noted by Walvoord et al (2012) and Liu et al (2022), streamflow during cold winter seasons is derived mainly from baseflow due to climate-driven permafrost thaw.…”

“…Then, the results of the above-mentioned calculations are plotted on a precipitation-temperature plane to demonstrate the streamflow-precipitation-temperature relationship. This approach can be applied to identify streamflow responses to climate change during particular periods (e.g., winter season, low flow periods) (Liu et al, 2022).…”

“…Recent studies have found that the rates of increase in both air temperature and precipitation were greater in permafrost areas than in nonpermafrost areas (Wang et al, 2021b;Wang et al, 2022a). Furthermore, the contribution of groundwater from thawing permafrost to streamflow in permafrost-dominated basins is likely to increase in the context of global warming (Lamontagne-Hallé et al, 2018;Jin et al, 2022;Liu et al, 2022). Therefore, the streamflow response to climate warming in permafrost-dominated basins will be more pronounced (Wang et al, 2021a).…”

The climate is warming much faster than the global average at the northern mid–high latitudes, leading to intensified hydrological cycles. However, it is unclear whether the response of streamflow to climate change is uniform across river basins with areas of 104–105 km2. In this study, monthly streamflow data from five river basins (Bol’shoy Patom, Chara, Olekma, Timpton, and Uchur) and gridded monthly temperature and precipitation data from the Russian South Yakutia at 53.5–61.5°N were analysed to investigate changes in their annual streamflow from 1934 to 2019 and their responses to climate warming. The results showed significant increasing trends in air temperature for all five basins at rates of 0.20°C–0.22°C/decade (p < 0.001), with faster warming after the 1980s. Apart from the Uchur River Basin, increasing trends in annual precipitation were observed in the other four river basins at rates of 9.3–15.7 mm/decade (p < 0.01). However, temporal changes in streamflow were much more complex than those in air temperature and precipitation among the five basins. Only two of the five basins showed significant increasing trends in annual streamflow with change rates of 17.1 mm/decade (p < 0.001) for the Chara River and 7.7 mm/decade (p < 0.05) for the Olekma River. Although the other three basins showed slightly increasing trends in annual streamflow (1.8–4.0 mm/decade), these trends did not pass significance tests (p > 0.05). By analysing the temperature-precipitation-streamflow relationships, we determined that the annual streamflow positively responds to precipitation, while winter streamflow is most sensitive to temperature. With climate warming, the streamflow during the winter period (October-April) increased significantly in four of the five river basins at rates of 1.4–3.1 mm/decade (p < 0.001), suggesting that warming-induced permafrost thawing increases baseflow. Although the streamflow response of large Siberian rivers to climate change is consistent, our results suggest that the streamflow response to climate change in relatively small river basins (104–105 km2) is much more complex.

Climate Change Risks to Freshwater Subsistence Fisheries in Arctic Alaska: Insights and Uncertainty from Broad Whitefish Coregonus nasus

et al. 2023

View full text Add to dashboard Cite

Arctic freshwater ecosystems and fish populations are largely shaped by seasonal and long‐term watershed hydrology. In this paper, we hypothesize how changing air temperature and precipitation will alter freeze and thaw processes, hydrology, and instream habitat to assess potential indirect effects, such as the change to the foraging and behavioral ecology, on Arctic fishes, using Broad Whitefish Coregonus nasus as an indicator species. Climate change is expected to continue to alter hydrologic pathways, flow regimes, and, therefore, habitat suitability, connectivity, and availability for fishes. Warming and lengthening of the growing season will likely increase fish growth rates; however, the exceedance of threshold stream temperatures will likely increase physiological stress and alter life histories. We expect these changes to have mixed effects on Arctic subsistence fishes and fisheries. Management and conservation approaches focused on preserving the processes that create heterogeneity in aquatic habitats, genes, and communities will help maintain the resilience of Broad Whitefish and other important subsistence fisheries. Long‐term effects are uncertain, so filling scientific knowledge gaps, such as identifying important habitats or increasing knowledge of abiotic variables in priority watersheds, is key to understanding and potentially mitigating likely impacts to Arctic fishes in a rapidly changing landscape.
