Prof. Lovegrove and colleagues masured body temperatures of six mammalian species and compared them with temperature of the enviromnent. They revealed that small tropical mammals are especially vulnerable to climate change due to their physiology. Increasing temperature can lead to changed metabolism and it is especially risky when the animals cannot move to colder areas (e.g. on islands). The results of the study that included also data collected by M. Řeháková on free-ranging Philippine tarsiers were published recently in Physiological and Biochemical Zoology (Lovegrove B. G., Canale C., Levesque D., Fluch G., Řeháková-Petrů M., Ruf T. (2013) Are Tropical Small Mammals Physiologically Vulnerable to Arrhenius Effects and Climate Change?).
