“…The current projections of temperature certainly do not reach levels that are likely to cause physiological stress, as the lethal temperature for bloater and cisco is near 26°C (Rudstam et al 1994 ). In other regions, climate warming projections predict negative effects on coregonids, such as Vendace ( Coregonus albula ) and Cisco ( Coregonus artedii ), by reducing suitable habitat with warmer temperatures (Elliot and Bell 2011 ; Kumar et al 2013 ). We also found variability in fish production expanding with the length of time forecasted due to the widening disparity of the different SNAP predictions for temperature further into the future.…”

Lake ecosystems in the Arctic are changing rapidly due to climate warming. Lakes are sensitive integrators of climate-induced changes and prominent features across the Arctic landscape, especially in lowland permafrost regions such as the Arctic Coastal Plain of Alaska. Despite many studies on the implications of climate warming, how fish populations will respond to lake changes is uncertain for Arctic ecosystems. Least Cisco (Coregonus sardinella) is a bellwether for Arctic lakes as an important consumer and prey resource. To explore the consequences of climate warming, we used a bioenergetics model to simulate changes in Least Cisco production under future climate scenarios for lakes on the Arctic Coastal Plain. First, we used current temperatures to fit Least Cisco consumption to observed annual growth. We then estimated growth, holding food availability, and then feeding rate constant, for future projections of temperature. Projected warmer water temperatures resulted in reduced Least Cisco production, especially for larger size classes, when food availability was held constant. While holding feeding rate constant, production of Least Cisco increased under all future scenarios with progressively more growth in warmer temperatures. Higher variability occurred with longer projections of time mirroring the expanding uncertainty in climate predictions further into the future. In addition to direct temperature effects on Least Cisco growth, we also considered changes in lake ice phenology and prey resources for Least Cisco. A shorter period of ice cover resulted in increased production, similar to warming temperatures. Altering prey quality had a larger effect on fish production in summer than winter and increased relative growth of younger rather than older age classes of Least Cisco. Overall, we predicted increased production of Least Cisco due to climate warming in lakes of Arctic Alaska. Understanding the implications of increased production of Least Cisco to the entire food web will be necessary to predict ecosystem responses in lakes of the Arctic.

“…Much of the work on the effects of climate warming on DO in lake hypolimnia is based on modelling studies that use output from global circulation models of future climate conditions, e.g. Blumberg & Di Toro (1990), Fang & Stefan (1997, 2009) and Elliott & Bell (2011). Long‐term data from Blelham Tarn provided an opportunity to investigate the extent to which hypolimnetic DO in a lake was actually affected by the combination of a warming climate and eutrophication over a 41‐year period (1968–2008).…”

1. We analysed 41 years of data from Blelham Tarn, U.K., to determine the consequences of eutrophication and climate warming on hypolimnetic dissolved oxygen (DO). 2. The establishment of thermal stratification was strongly related to the onset of DO depletion in the lower hypolimnion. As a result of a progressively earlier onset of stratification and later overturn, the duration of stratification increased by 38 ± 8 days over the 41 years. 3. The observed rate of volumetric hypolimnetic oxygen depletion (VHOD obs ) ranged from 0.131 to 0.252 g O 2 m )3 per day and decreased significantly over the study period, despite the increase in the mean chlorophyll a (Chl a) concentration in the growing season. The vertical transport of DO represented from 0 to 30% of VHOD obs , while adjustments for interannual differences in hypolimnetic temperature were less important, ranging from )11 to 9% of VHOD obs . 4. The mean wind speed during May made the strongest significant contribution to the variation in VHOD obs . VHOD obs adjusted for the vertical transport of DO and hypolimnetic temperature differences, VHOD adj , was significantly related to the upper mixed layer Chl a concentration during spring. 5. Hypolimnetic anoxia (HA) ranged from 27 to 168 days per year and increased significantly over time, which undoubtedly had negative ecological consequences for the lake. 6. In similar small temperate lakes, the negative effects of eutrophication on hypolimnetic DO are likely to be exacerbated by changes in lake thermal structure brought about by a warming climate, which may undermine management efforts to alleviate the effects of anthropogenic eutrophication.

“…It remains to be explored how cold-water fish assemblages in lakes respond to warming if these temperatures exceed the thermal windows of the organisms such that no cold-water refuge is left even in deep lakes. These effects may become more severe when warming is coupled with oxygen depletion in cold deepwater habitats (Elliott and Bell 2011).…”

Discrete thermal windows cause opposite response of sympatric cold-water fish species to annual temperature variability

Ecosphere 2(9):104. doi:10.1890/ES11-00109.1Abstract. Cold-water fish populations in lakes are predicted to be most vulnerable to global warming due to their geographical isolation and their requirement for habitats with low temperatures. In contrast, higher fisheries catches of cold-water species often correlate with warmer winter and spring temperatures. Mechanistic understanding of the relationships between annual temperatures and population densities can only be achieved by integrating physiology and behavioral ecology of the focal species, an approach that has so far not been applied to freshwater fish populations. We took advantage from a unique biological system, the coexistence of two cold-water Coregonus species in a deep lake. These fish species show discrete thermal windows (4-58C vs. 7-98C) and life histories (spring-vs. autumn-spawning). We analyzed short (6-11 years) time series of pelagic fish densities obtained by hydroacoustics and trawl catches, their zooplankton prey densities, and water temperature in Lake Stechlin (Germany). Young-of-year fish densities increased after warm winters. In contrast, densities of juveniles and adults were correlated with metalimnetic June temperatures, but an opposite response direction of the sympatric species was caused by their discrete thermal windows. Densities of the species with a 4-58C thermal optimum increased in years with warm June, whereas densities of the other species with a 7-98C optimum declined in these warm years. The occupied depths of both populations at night shifted towards less suitable water temperatures if densities of the competing species increased, suggesting interactive niche segregation. Therefore, growth of fishes may be reduced and hence mortality increased by additional metabolic costs induced by occurrence in layers outside of the metabolic optima. Temperature-driven inter-and intra-specific competition in the metalimnetic layer may cause a complex response of cold-water fish assemblages in lakes to warming. More approaches testing the relative performance of interacting species are needed to improve predictions on the consequences of global change on lake ecosystems.
