Global warming can change the color of the butterflies
A study recently published-and it took 18 years to develop â€" concluded that the butterflies and dragonflies of light colors thrive in warmer environmental conditions â€" and that the butterflies and dragonflies darker prefer the colder climates. The investigation examined the natural habitats of these insects in Europe during the many years in which it took place.According to the investigation, the body of these insects plays an important role in the absorption of energy by the Sun, which serves as fuel for the flights and to regulate body temperature. The insects of darker colors absorb more solar energy than lighter colors and therefore can survive in colder climates. By contrast, the lightest insects survive better in warmer climates, since they can reflect sunlight and not sobreaquecem.According to these new findings, climate change means changes in habits of various insects. "We know that the butterflies and dragonflies clearer better adapt to warmer climates and also we have shown that the effects of climate change in the places inhabited by species are not future consequences but rather gifts, with nature and ecosystems to change in real time," says Carsten Rahbek, of Imperial College London and author of the study."We demonstrated for two major groups of insects a direct connection between the climate and its color, which has impact on geographical distribution," explains the researcher. This means that in the future, with the rising temperatures of the planet, butterflies and dragonflies darker can evolve and become gradually lighter to support better the warmer temperatures.The team of researchers analysed data on the location of Pan-366 species of butterflies and dragonflies species 107 between 1988 and 2006. The colors were analyzed from the wings and bodies and created maps with the locations where the insects can be found.Foto: tdlucas5000 / Creative Commons
