Impacts on species physiology in terrestrial and freshwater systems have been observed, and attributed to climate change . These include changes in tolerance to high temperatures , increased metabolic costs of living at elevated temperatures  and shifts in sex ratios in species with temperature-dependent sex determination. For example, warmer temperatures have driven the masculinisation of lizard populations  and the feminisation of turtle populations . Skewed sex ratios can lead to mate shortages, reduced population growth, reduced adaptive potential and increased extinction risk, because genetic diversity decreases as fewer individuals mate and heterozygosity is lost .
