[Study of reconciliation in anubis baboons].

The study of post-conflict reconciliation in corral living anubis baboons was carried out. It was established that more than third part of the all the conflicts were followed with reconciliation, and the mean value for the frequency of reconciliation tendency was 27.3 +/- 2.4. The frequency of reconciliation in different categories of conflicting pairs of animals was comparable. 75% of cases of reconciliation occurred during the first 2 minutes after the conflict. Use of definite behavioral patterns by the individuals for demonstration of reconciliation depended on sex of the participants and on their role in the conflict. Differences in the indices of reconciliation tendency in high and low rank monkeys were found.

[Infanticide in hamadryas baboons].

The results of 20-year study of infanticide cases in hamadryas baboon troop of the Sukhumi colony and 10-year observations in Gumista Natural Reserve are presented. The allopatric behaviour which may be the cause of infant death, is shown to be common for 4-7 year old males. In behaviour of older males directed to the infants the elements of aggression predominate. The majority of injuries and infanticide by males takes place in the situations associated with a dominant male change in the group or with the introduction of new females into the groups. In the groups where the social relationships are not fully organized, the appearance of infant leads to decrease of dominant male function and to appropriation of infant by a male and its traumatizing. As a result of infanticide the infants of young 4-7 year old females die most of all. The death of infants commonly occurs during the introduction of young males into the group. The probability of infanticide during the introduction of older males is lower.

[Development of a method for creating a colony of Macaca mulatta, free of herpes B virus infection].

To form the colony of monkeys, free of herpes B virus, the serological study was made with the aim of finding out the carriers of this virus. 482 rhesus macaques (Macaca mulatta) from the Adler monkey house were examined for the presence of antibodies to herpes B virus by the method of point immunoblotting with the use of Herpes virus simiae as antigen. The contamination of monkeys in different open-air cages varied from 12.5% to 92%. In different age groups, it was 27% in nonpubescent monkeys (49 out of 182 animals), 55% in adolescent monkeys (55 out of 99), 73% in pubescent monkeys (131 out of 179) and 95% in monkeys over 15 years (21 out of 22 animals). 9 groups of rhesus macaques (comprising altogether 81 animals), free of herpes B virus, were selected. The monkeys were repeatedly tested within a year; after that 10-17% of formerly seronegative monkeys were rejected and removed from the selected group. After the third testing 2.5% more of the animals were found to have seroconversion. The colony of rhesus macaques thus created exists at present. The animals are subjected to constant serological observation.
