[Changes in predatory and intraspecific aggressiveness of the male rat during food deprivation].
A significant intensification of intraspecies aggression of mice-killing male rats was manifest under the influence of food deprivation, judging by two aggressive reactions of rats-residents towards intruders and by the number of rats performing such reactions. In conditions of free access to food, the mice-killing and not mice-killing rats did not differ by their intraspecies aggression.
