Florian Altermatt is an ecologist — a scientist who studies how creatures interact with their environment — who works at the University of California, Davis. In a new study, he and other researchers looked at changes in the reproduction patterns of butterflies and moths in Central Europe. Over the last 30 years, the average temperature in Central Europe has gone up about 1.5 degrees Celsius. During that same time, 44 species of moths and butterflies in an area around Basel, Switzerland, have added an extra generation to their numbers during some years.
Two butterfly species, the small heath (left) and common blue (right), are among those in Central Europe that have become more likely in the last 30 years to have an extra generation in the same year. Since 1980, average temperatures there have also risen.To read more on this, please CLICK THE TITLE ABOVE.
