Climate change affects cold blooded animals!

Cold blooded animals such as lizards, insects, and fish have a specific range for their body temperature in order to hunt, eat, move quickly, and reproduce. Increasing temperatures puts this range at risk and therefore, the animals survival at risk. Although, researcher Manuel Lealan associate professor of biological sciences at the University of Missouri “We’ve done very well at saying climate change will have an impact on ectotherms, but we’ve done less well at saying how they will be effected,”.

Therefore, researchers had to further study in detail the effects of the climate change. After proposing a conceptual framework they found that the cold blooded animals behaviors, such as eating and mating, are very sensitive to thermal change, especially when compared to the animals sprinting speed. A physiological trait that is used in most studies to find climate change effects.

Furthermore, the researchers concluded that,”Our analyses show that the physiological performance of A. cristatellus in dry habitats will decrease by about 25% under future warming, but that their activity budgets will decrease by 50%. Furthermore, the habitat will become much less suitable for reproductive behaviors, which are of course critically important for populations to avoid extinction.” In other words, at the increasing rate of temperature cold blooded animals may ultimately become extinct, due to their inability to reproduce.
