Ecological genetics of beetles of the genus Adalia: populations of A. bipunctata of NorwAy and Kola peninsula

Cover Page

Abstract


The composition of 5 populations of Adalia bipunctata L. of the Norway and two populations of the Kola Peninsula was stu died. The proportion of black color imago in them varies from 0% to 35.7%. The composition of the populations of A. bipunctata inhabiting the Arctic Circle is described for the first time. Standard correlation analysis did not reveal a significant dependence of the proportion of black individuals, both on the latitude of habitats, and on their climatic parameters. Application of the logistic regression method to these data made it possible to show that the abundance of black morphs is positively associated with the average winter temperature, and is negatively correlated with summer moisture and mean temperature. Basically, these data are determined by the peculiarities of the Bergen population, where the greatest concentration of melanists is observed, and the climatic conditions (according to the average winter temperature, humidity and annual amount of atmospheric rainfall) differ sharply from the conditions of all other studied places on the coasts of Norway and the Kola Peninsula.
