High altitude stress
WebSeeds of the montane population were more sensitive to both types of water stress. A predicted increase in the frequency and intensity of extreme high rainfall or drought events may predispose early stages of this population to adverse factors, which might negatively affect population viability along elevational in future climate change scenarios. WebAir pressure decreases exponentially as altitude increases, as shown in the graph below (Figure 6.6.2). Figure 6.6.2 As altitude increases, atmospheric pressure decreases, which means there are fewer molecules of oxygen in a single breath at high elevations than a single breath at lower elevations. At sea level, air pressure is about 100 kPa.
