Cover: The cane toad (Rhinella marina) has been introduced throughout the Pacific from its native range in South and Central America. In Australia, the toad has become invasive and vastly expanded its range; however, its spread to cooler areas is relatively slow. Seebacher and Franklin (pp. 1437−1444) show that exercise physiology, e.g. oxygen transport by the cardiovascular system, is optimised at higher temperatures. Interestingly, exercise at cooler temperatures requires relatively more energy, which is increasingly supplied by non-sustainable anaerobic processes. Hence, there is a link between exercise physiology and invasive success, which means that cane toads will fare well under global warming. 2 2
