Additionally, climate change can potentiate Bd's spread indirectly; as temperatures have warmed, many amphibian species (e.g., Bustamante et al. 2005; Raxworthy et al. 2008) as well as plant, insect, and other animal species are expanding (or shifting) their elevational range upwards (for a general review on climate change-induced elevational range expansion see Parmesan 2006).
