Comparative chromosomal analysis of populations of phytophilous chironomidae Glyptotendipes glaucus (Mg.) from Chernobyl affected territory

Comparative chromosomal analysis of populations of phytophilous chironomidae Glyptotendipes... The karyopools of the phytophilous chiromomid species of Glyptotendipes glaucus (Mg.) were studied. Chironomids originated from a number of reservoirs located in the Novozybkovsky raion of the Bryansk region, which was affected by the Chernobyl radioactive release, and two reservoirs located in the Saratov region. Differences in the inversion spectrum and frequencies, both among Bryansk and between Bryansk and Saratov populations, were found. There were no new inversions in the Novozybkovsky populations; however, structurally small rearrangements in long chromosomes were noted. Typical abnormalities included mosaicism of the chromosome morphotypes in cells of the same saline gland, which was especially distinctive in the larvae from the forbidden zone; decondensation of the telomere regions of chromosomes; and mosaic asynapsis of the chromosome IV homologs (up to complete disjunction). Also, several larvae were polyploids. Other species of Glyptotendipes inhabiting the Novozybkovsky reservoirs were represented by the single species of G. paripes (near the Korchy settlement). The karyotypes of its several larvae were represented by an unorganized chromosomal substance. The other Glyptotendipes species seem to have lower adaptive abilities under the conditions in question and were eliminated from precatastrophe biotopes, while G. glaucus succeeded in adaptating to the new environment.
