The adaptive response (AR) by micronuclei test in bone marrow cells of rodents with high migration activity (pigmy wood mouse, field mouse) from the Eastern Urals Radioactive Trace (EURT) zone and control areas was investigated. Similar dynamic of AR’ formation in mice from both the EURT and adjacent areas was revealed. We conclude, that such adaptive reaction is connected with rodents’ migrations in the narrow and extended EURT zone, which essentially decreases the probability that certain adaptations changes will be fixed and inherited in a series of generations of animals with high migration activity.
Проведено изучение адаптивного ответа (АО) по микроядерному тесту в клетках костного мозга грызунов вагильных видов (малая лесная мышь, полевая мышь) из зоны Восточно-Уральского радиоактивного следа (ВУРСа) и фоновых участков. Выявлена сходная динамика формирования АО у животных из парных выборок (ВУРС-контроль), что связано с миграциями грызунов на узкой протяженной территории ВУРСа, которые существенно снижают возможность закрепления адаптивных приспособлений в чреде поколений у животных с высокой миграционной активностью.
