If global warming will continue to gain momentum, the first living creatures who will disappear him from the face of the Earth, will become lizards. According to the American scientists from Clemson University, to climate change cold-blooded reptiles to adapt will not.
According to scientists, the more hot it will become in the habitats of lizards, the harder it is for these animals to maintain optimum body temperature. When reptiles will “overheat”, they will need to look for a shadow, and the more similar will happen, the more time and effort the lizards have to spend on this quest.
Specialists conducted a series of experiments involving animals, and also built a computer model that allows to understand how the lizards will affect climate change.
In the study, specialists found out that the most comfortable lizards feel only the territories covered with many small shadows (e.g. from grass), but not where there is a large “solid” shading (e.g. from trees). According to scientists, climate change will affect the vegetation and its distribution in such a way that suitable for lizards of the shadows to become smaller, while the demand for them will only increase. Ultimately, this can lead to the disappearance of lizards, at least, those who today inhabit hot regions.
A few years ago, a number of studies have shown that to the 80-th years of the current century due to global poteplenie disappear 40% of lizards, and 20 percent of existing species will cease to exist completely. However, according to the authors of a new study, their predecessors came from the fact that to find the shadow of the lizard is not difficult, and did not take into account that this requires time and effort, so the results were too “optimistic”.
