The present issue of Scientific Research in Zoological Parks covers different
aspects of the Zoo management. A number of articles are dedicated to the keeping
and breeding of reptiles, including revue on Boiga genus in captivity. New
veterinary methods for snakes and the results of the field studies of reptiles are also
provided. The sequel series of articles on marine aquariumistics are included in the
current issue. Ethologycal papers describe the effects of visitors’ presents on the
behaviour of zoo animals, discuss the issues of the ontogenesis of behaviour,
assess the methods of environment enrichment of primates. One of the papers
presentes unique experience of the social adaptation of the hand-reared orangutan.
Various aspects of the management of mixed-animal exhibits are discussed in two
papers. “Information” section provides a comprehensive report on the International
Workshop on Biology and Conservation of Canids.
The issue can be of useful for the zoo experts and keepers, as well as for the
students of biological universities.

Summary
Vabischevich A.P., Voschanova I.P., Volodin I.A. Influence of visitors on
time budget in the dhole. Observations on six dholes from two groups exposed in
Moscow Zoo were conducted. Three behavioural forms: active behaviour,
nonactivity (rest) in outdoor enclosure and presence in indoor hide were registered
using scan sampling method (total number of scans – 1305). In presence of visitors
five of six animals scans have been spending noticeably less time outdoors, by
most part, due to decrease of resting portion. The changes were especially evident
in young animals: their presence in indoor hides did increase up to 70% of the
whole time budget.
Summary
Chaadaeva E.V. Development of vocal behaviour during early postnatal
ontogeny of banded mongoose (Mungos mungo).The juvenile vocalizations in the
banded mongoose were studied. The investigation is based on observations of 11
juveniles from three litters. Vocalizations of the isolated juveniles, situated out of
nest site, were recorded on 7th and 30th days of life. Besides, the results of
observations on animals behavior within a famili group, included 2 adults and 9
juvenils 30th days old, have been analized. Juvenile vocal repertoire consists of
squeak, whistle, trill и chattering/twittering. The vocalizations are well
distinguished by the parameters. Composite trill-like signals of neonates perform
the function of "infant call" and consist of two parts: whistle and trill. Up to 1
month of life the predecessors to adult cackle-signal are appeared by organizing
single squeaks in homotypic stanza vocal sequences. No sign of aggression in
behavioural repertoire of the young animals was noted up to 35th days of life. Thus,
agressive behaviour in banded mongoose forms later in ontogeny.
Summary
Nikitin D.B., Benediktova I.V. Changes of behavior of suricates (Suricata suricata)
during female’s pregnancy and experience of handrearing. Behavior of a pair of
suricates was studied to predict the date of delivery. Frequency of change of
different poses and movements was used as an index to characterize the behavior
of animals. The newborns from the IX litter (4.0, born 26.12.99) were successfully
handreared from the 1st day. The detailed scheme of their feeding and necessary
procedures is described.
Summary
Zubchaninova E.V.. Behavior of Amur leopard (Panthera pardus orientalis) in
Moscow zoo. Report 1.Time budgets and enclosure employment. Changes in time
budgets and enclosure employment of amur leopards in Moscow zoo are analysed.
Origin of behavioral pathologies is discussed. Dependence of some budget
parameters on seasons, sex of animals, their health and construction of cages is
revealed. Increasing of stereotypy in combination with decreasing of moving
activity, long-term presence in shelters and absence of interest in outdoor events
indicate the decrease of welfare of leopards. Providing of adequate captive
environment for amur leopards is discussed.
Summary
Zubchaninova E.V.. Behavior of Amur leopard (Panthera pardus orientalis) in
Moscow zoo. Report 2. Visitors’ effect on behavior of leopards. Behavior of
amur leopards dependent on visitors’ quantity in the zoo is analysed. As human
number near the enclosure rises the quota of anomalous moving activity
(stereotypy) grows; the animals move to the most distant from the visitors part
of the enclosure. Small amount of visitors provoke the interest of leopards.
Movement of animals inside the enclosure proves to be a regulator of external
stimulation optimal level.

animals usually use all space of enclosure, they demonstrate more behavioral
patterns and are more active. Multispecies groups are very attractive for visitors.
Summary
D.A.Astakhov, S.Y.Poponov,V.R.Poponova. Breeding of five species of
anemonefishes at Moscow Zoo. Spawning pairs of five species of
anemonefishes has been formed during 1997-1999 at Moscow Zoo. It is well
known that the success in rearing of marine fishes is based on the nutritional
quality of planktonic organisms used as a food for fish larvae. The rotifer
Brachionus plicatilis is used all over the world as the first food item in intensive
cultures of marine fish, but nutritional quality of rotifer depends on a particular
species and quality of unicellular algae used for maintaining rotifer´s culture. In
1998, dense (10106 cells/ml), pure and stable cultures (on f/2 medium) of five
species of unicellular algae (Nannochloropsis sp. (Chlorella sp. f. marina),
Dunaliella tertiolecta, Phaeodactylum tricornutum, Rhodomonas salina) were
started.
In 1998, rotifer culture fed by the culture of unicellular alga
Nannochloropsis sp. (Chlorella sp. f. marina) was used for rearing in pure water
Premnas biaculeatus during the first 30 days. Starting from the 20th day newly
hatched nauplii of brine shrimp (Artemia salina) were added to rotifers for
nutrition of juveniles. Survival ratio (to 3 months) of P. biaculeatus was 12.5%.
In 1999, rotifer culture fed by the mixture of two cultures of unicellular
algae (Nannochloropsis sp. (Chlorella sp. f. marina) – 90%, Dunaliella tertiolecta –
10%) was used for rearing in "green" water Amphiprion ephippium and
A.melanopus during the first 25 days. Starting from the 17th day newly hatched
nauplii of brine shrimp (Artemia salina) were added to rotifers for nutrition of
juveniles. Survival ratio (to 1 year) of A. ephippium was 17% and that of
A.melanopus was 15% .
In 2000, rotifer culture fed by the mixture of three cultures of unicellular
algae (Nannochloropsis sp. (Chlorella sp. f. marina) – 75%, Phaeodactylum
tricornutum - 20 %, Rhodomonas salina - 5%) was used for rearing in "green"
water Amphiprion ocellaris during the first 16 days. Starting from the 12 day
newly hatched nauplii of brine shrimp (Artemia salina) were added to rotifers for
nutrition of juveniles. Survival ratio (to 1 year) of A. ocellaris was - 52 %.
In 2000, rotifer culture fed by the mixture of two cultures of unicellular
algae (Nannochloropsis sp. (Chlorella sp. f. marina) – 70% and Phaeodactylum
tricornutum - 30 %) was used for rearing in "green" water Amphiprion polymnus
during the first 16 days. Starting from the 12 day newly hatched nauplii of brine
shrimp (Artemia salina) were added to rotifers for nutrition of juveniles. Survival
ratio (to 1 year) of A. ocellaris was - 18.5 %.

Summary
Tarkhanova M.A. The influence of intraspecific competition on the life of
Barnacle goose (Branta leucopsis) in the mixed waterfowl exhibit of Moscow Zoo.
Large mixed exhibits of waterfowl afford good opportunities to study the behavior
of different species. The influence of intraspecific competition on the Barnacle
goose’s life in such exhibits of Moscow Zoo is discussed. The significance of
different species on Barnacle goose depends upon their quantity and ecological
closeness. Autumn and winter are the most critical periods for this species in
Moscow Zoo, because the intraspecific competition for food becomes much
stronger. The feeding of Barnacle geese is frequently interrupted by the aggressive
attacks of larger and stronger snow geese (Chen caerulescens) and sometimes
Bewick’s swans (Cygnus bewickii). The competition for food can increase the
mortality of Barnacle goose in winter and possibly contributes to the poor hatching
success.
The shortage of available nest sites is another limiting factor and the cause of
inter- and intraspecific competition in spring. During this period most aggressive
attacks of Barnacle geese is intraspecific, but the interspecific aggression is also
very important. Snow geese and some other stronger species can even exclude
Barnacle geese from suitable nest sites.
As a result of the study some recommendations about the husbandry of Barnacle
goose in the mixed exhibits of waterfowl in Moscow Zoo are made.
