EUROASIAN REGIONAL ASSOCIATION OF ZOOS AND AQUARIA GOVERNMENT OF MOSCOW MOSCOW ZOO Scientific Research in Zoological Parks Volume 22 Moscow 2007 The previous 21st issue of Scientific Research in Zoological Parks has been published by Novosibirsk zoo, the current one is presented by Moscow zoo. Traditionally it is dedicated to different aspects of the zoo management. Series of articles on marine aquariumistics and husbandry and breeding of venomous snakes is continued. Reviews devoted to research activity of zoos in the territory of former USSR, viral diseases of reptiles, problems of mammals' behavior optimization in zoos are presented. Behavior of a group of giraffes and sugar gliders captive population is discussed. Problematic articles consider reintroduction as a method of wild Amphibia conservation and a method of “individual distances” for behavior research. Other articles describe animal keeping in Budapest Zoo, preservation of gene pool of the Przewalski horses at Askania Nova, methods of keeping and breeding Inachis io and endangered Oriental White Stork. We made a decision to publish the translation of “Husbandry Guidelines 2006 - Common warthog” which is of great interest for keepers and also sets an example of similar reports. Brief communication describes the first successfull hand rearing jerboas. Information on the I st European Congress on Conservation Biology "Diversity for Europe" and conservation project «The saving of Meriones dahli” is cited. The issue will be useful for zoo experts and keepers, as well as for students of biological universities Summary Tkacheva E.Yu., Tkachev O.A.

Summary Zubchaninova E.V. Behavior of a group of giraffes (Giraffa camelopardalis giraffa) in an outside enclosure of Moscow zoo. This article continues our study (2004) on adaptation of two young giraffes to adult animals-residents. Observations were conducted in summer, 2005 when the group of giraffes was in outdoor enclosure. Decrease of locomotion and time for rest as well as increase of feeding time was discovered. Feeding preferences in young animals were revealed. Social environment in outdoor enclosure was found to be more favourable for giraffes basing on examination of their interactions. Recommendations for more rational disposal of feeding places were given after study of enclosure employment. Summary Zubchaninova E.V., Morozova E.Yu., Dubrovskyi V.Yu. Can a plastic salt-lick toy be a factor of giraffes enrichment? A plastic salt-lick toy with smell and flavouring settings was used to decrease stereotype licking of different objects in giraffes in the Moscow zoo. This toy practically didn’t effect the intensity of licking in contrast to hay availability. Individual attitude of different animals towards salt-lick and licking of partners’ hair was noted. Summary Kondratyeva L.V., Ilchenko O.G. Behavior of sugar gliders (Petaurus breviceps) captive population in Moscow Zoo. 1. Behavioral patterns. Ethogramm of gliders social and individual behavior was composed (78 elements combined in 13 functional groups). Description of social behavioral complexes (peaceful, sexual and agonistic) and individual behavior (calm and during psychological discomfort) was made. To help in recognition of animals conditions, four listed types of behavior element–markers were picked out. Summary Serbinova I.A. Reintroduction as a method of wild Amphibia conservation. The problem of amphibian species diversity conservation is extremely actual to date. Such methods as captive prolonged keeping, crioconservation of gametes and reintroduction of raised captive born offspring to natural habitats can help to solve the problem. Reintroduction of endangered Pelobates syriacus in Georgia started in 2004 and covered natural habitats of the species near to Tbilisi (2004 and 2006) and Gori (2005). At the same time monitoring of hatching ponds of Pelobates syriacus in Georgia was carried out. Now there is a clear informatiom of Pelobates syriacus distribution and density in the most parts of Georgian area. The work to be continued. Summary Syroechkovski E.V., Tarkhanova M.A. Behavior reseach of Barnacle geese in captivity using a method of “individual distances”. About 30 Barnacle geese (Branta leucopsis) are kept at the Moscow Zoo. All the birds are identifiable through individual marking by colour rings. Their behaviour has been observed since 1998 and now we know the life history of every bird. Barnacle geese are very sociable in all seasons, but during autumn and winter their activity is very low and interactions are few. During these periods all Barnacle geese often stay in a flock consisting of several groups and it's difficult to study their social structure and to determine whether the members of the observed groups are related. In order to understand the relations of the group members a method of “individual distances” was used. This approach is based on the analysis of the spacial distribution of Barnacle geese in the flock, measuring mean distances between birds and comparison of these distances. The presence of statistically significant difference in mean distances between the birds in the flock would be the evidence of some positive or negative relationship between them. This means that the specimen of Barnacle geese can identify every bird in the flock and while moving each goose prefers to stay closer to some birds and farther from others. In our analysis we have used a number of parameters including: mean distance, maximum and minimum distances and coefficient of distance variation. We also registered how often birds were found in different groups. The lowest mean distances are between parents and their youngest offspring and partners in pairs. We found out that family bonds were very strong in Barnacle geese. Parents were tolerant to their older offspring in autumn and winter. Older offspring maintained a greater distance from parents than yearlings and were often on the perimeter of family group. The proportion of time offspring spent with parents declined as they grew older. Barnacle geese remained associated with their parents for a long time – they were observed together at least for 6 years. Adult offspring could occasionally leave and then rejoin their parents but they often stayed not far from them. The persistence and stability of family bonds were maintained mainly by males because sons preferred to stay close to their fathers. When the son found a breeding partner a new couple usually joined his parents. So we can conclude that a large social group of Barnacle geese with more than two adult birds may consist of more than one generation of offspring. Several generations of geese act as a large but loosely associated family. Summary Popov S.V. Research activity of zoos in the territory of former USSR. The article discusses scientific activity of the regional zoos (researches, conservation programms, publishing and methodological activities) basing on analysis of 352 publications and questionnaires from 18 zoos. Summary Volodin I.A., Volodina E.V. Approaches to animal keeping in Budapest Zoo. Budapest Zoo is among oldest in Europe (founded in 1866) and is situated on a small territory of 11 he. However, it exposes a lot diversity of animals. It is achieved for the account of very reasonable species selection, that allows keeping animals in mixed expositions and providing them large enclosures; for the account of terraced exposition and constant use of warmed pavilions. Principles of exposition design, environment enrichment, approaches to visitor feedback as well as technical decisions to enclosure construction, simplifying work with animals, are described. Summary T.L. Zharkikh, N.I. Yasynetska. Preservation of gene pool of the Przewalski horses at Askania Nova: breeding in lines. A brief history of preservation and breeding of the Przewalski horse in captivity is given in the article, classification of the population in breeding lines and prospects of their further preservation are discussed. Summary Vasiliev D.B., Shved V.S. Viral diseases of reptiles. Main forms of reptile diseases caused by retroviruses, reoviruses, paramyxoviruses, flaviviruses, herpesviruses, adenoviruses, iridoviruses, and poxviruses are considered. Matters of systematics of virus agents, clinical signs and pathomorphologic alterations caused by diseases are discussed, as well as current diagnostic methods, differential diagnostics and therapy. Summary Neprintseva E.S., Voshchanova I.P. Scientific researches on optimization of mammals' behavior in zoos: a review. Scientific researches which deal with behavioral problems and psychological well-being of captive animals have received advanced development over the last decades and play an important role in providing an adequate animals captive environment for up-to-date zoos. The main approaches to optimization of behavior – environment enrichment, theoretical basis of improvement of animals’ psychological state, analysis of causes of pathological behavior and studying of rearing conditions effects on behavior are reviewed here in apply to mammals in captivity. Conclusion resumes strategy of optimization of mammals' behavior in zoos. Summary Ilchenko O.G., Vakhrusheva G.V., Sapozhnikova S.R. Hand-rearing great jerboas: our first experience. Three great jerboas were successfully hand-reared in Moscow zoo in May-June, 2007. The appropriate intervals between feedings and milk formula were developed basing on our previous experience. We suppose the experiment was a success also due to the fact that the female was rearing the litter during first 2-3 weeks by herself. The very fact of nursing the litter by jerboa female in captivity is of great interest and rariry; it could be caused by preliminary homeopathic treatment. Summary st Maksudov G. I European Congress on Conservation Biology. "Diversity for Europe". Eger, Hungary, 22-26 August 2006. This item is a short description of main events of the Congress. The subject matters of 4 plenary talks, 16 symposiums, 22 sessions, 10 workshops are listed. Author regrets that among 1100 participants were only 7 Russians and only 1 Moscow representative. Many participants exclude Russia from Europe in their reports or know nothing about Russian biological science. Summary. Popov S.V., Iltchenko O.G. «The saving of Meriones dahli (Shidlovski, 1962)» (The first steps of Dahl’s Jird conservation project). The first results of Euro-Asian Regional Association of Zoos and Aquaria conservation project are reported. Dahl’s Jird is the most endangered rodent species in the territory of the former Soviet Union. According to our inspections in 2005 and 2006 the populations of Dahl’s Jird in Armenia have directly disappeared. At the same time Turkish zoologists found out that the population of Meriones meridianus in the east of Turkey is actually the population of M. dahli. So, our future plans are: to try to get Dahl’s Jirds from Turkey, breed them for establishing the stable captive population and then reintroduce the stock of the population into the late habitats in Armenia.
