AN example of a bizarre occurrence regarding a species of frog date from the summer of 1995,when 'an explosion'of multi-coloured frogs of the species Ran a klepton esculenta occurred in the Netherlands. Normally these frogs are brown and greenish- brown,but some unknown contributory factor is turning these frogs yellow and/or orange. Nonetheless,so far,the unusual bi- and even tri- coloured frogs are functioning similarly to their normal-skinned contemporaries. It is thought that frogs with lighter coloured skins might be more likely to survive in an increasingly warm climate due to global warming.
One theory put forward to explain extinct amphibian species that seems to fit the facts concerns the depletion of the ozone layer,a well-documented phenomenon which has led to a sharp increase in ultraviolet radiation levels. The ozone layer is meant to shield the Earth from UV rays,but increased radiation may be having a greater effect upon frog populations than previously believed. Another theory is that worldwide temperature increases are upsetting the breeding cycles of frogs.
