Аннотация:Two populations of laboratory mice lived outdoors in open pens for two years. Thereafter, some of them were bred in the laboratory. Morphometric analysis showed that the size of the synaptic projection area of mossy fibers (in the CA3 region of the hippocampus), which has an important functional role, and some behavioral traits of the open-pen mouse progeny had significant genetically determined differences from those in the initial population. This was attributed to differential breeding accounted for by the influence of severe environmental factors. Under environmental stress, selection occured in the population and the mice with behavioral and neuromorphological characteristics differing from the control group proved to be bette adapted to such conditions.
