In an integrated fashion this approach gave the opportunity to elaborate certain key problems of theoretical and practical zoology. Significant changes have taken place during the XX century of the genetic structure of populations and groups of closely related fish species, 6 new ones are reported from Ukraine for the first time. Immunogenetic evidence is provided on the heterogenity of the parent and hybrid populations of green frogs of the Rana esculenta complex. The stability of incorporated alleles has shown remarkable stability in the region of the Middle Dnieper. Evidence is provided on the hybridization between the created newt and the Danubian newt. It has been shown in these species that the genetic instability and disturbance of premeiotic elimination is strictly located in the geographicalsense. Mapping has been completed of the hybrid zone between the two species of Bombina in the Carpathian area. A quantitative assessment has been made of the tempo of reduction of morphological structures in mammals. Populations of malaria mosquitos from the Lower Dnieper have been investigated, changes and chromosome inversions have been summarized. Pterygomorphism amongst Gerridae of the Ukrainian fauna have been studied, recorded changes are summarized over a period of 20 years.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
