Background. Cryptotympana atrata and Hyalessa fuscata are the most abundant cicada species in the Korean Peninsula, where their population densities are higher in urban areas than in rural ones. The urban heat island (UHI) effect, wherein human activities cause urban areas to be significantly warmer than surrounding rural areas, may underlie this difference. We predicted a positive relationship...

Therefore, the quality of the estimates and projections made is highly dependent on the quality of the basic information permitting the calculation of the proportion urban. Such information consists normally of complete counts of both the total population...
