et al., 2014; Kraaijenbrink et al., 2017), are projected to reduce water availability and cause declines in biodiversity in high altitudes through local extirpations and species extinctions in regions of high endemism. Lake nutrient dynamics are expected to change, for example, at 2ºC warming, and net increase in CH4 emissions by 101-183% in hypereutrophic lakes and 47-56% in oligotrophic lakes in Europe are projected . Similarly, under the high- GHG emission scenario, lake stratification is projected to begin 22.0 + 7.0 d earlier and end 11.3 + 4.7 d later by the end of this century . While overall future trends on climate change on freshwater species and habitats are largely negative, evidence indicates that different species are projected to respond at different rates, with interactions between species expected to be disrupted and which may result in novel biological communities and rapid change in ecological processes and functions .
