title: [Changes in reproductive function during chronic isolation and increases in the population density of rats with different typologic behavioral characteristics].
abstract: It has been shown on white outbred female rats that animals with a strong balanced mobile nervous system and active-search behaviour had the greatest stress resistence against the action of chronic isolation and increase of population density. Weak non-balanced excitable animals with non-directed motor restlessness had a minimal resistence against stress.
