Ecological genetics of beetles of the genus <i>Adalia</i>: restructuring of <i>A. bipunctata</i> populations as a global warming effect

Abstract

The dynamics of the composition of the populations of Adalia bipunctata L. in St. Petersburg and Yalta (Crimean Peninsula) for 4732 years has been studied. The proportion of black individuals in them decreased by almost 2 times. Comparison of the composition of populations with climatic features of habitats (average annual temperature) showed that the proportion of black individuals in the population negatively correlates with the average annual temperature of the previous year. The observed change in the composition of geographically remote populations is probably the effect of global warming.
