The purpose of this study was to examine the influence of environmental enrichment on cats in captivity. The observation was carried out in Warsaw ZOO. Three species: puma (1:1), jaguar (1:1) and ceylon leopard (1:1) were observed. The data were collected from May to November 2000. Each week of observation was represented by three consecutive days (I - baseline, II and III - with enrichment). As regards...
In our research we tried explain the high genetic similarity among modern Wisent and domestic cattle. The genetic material was taken from different species of Bovidae family including aurochs. The control region of mitochondrial DNA and the sequence of gene 16S rRNA were subject to analyses. To compare the species we estimated genetic distance and constructed phylogenetic tree. The high level of similarity...
The clutches of pond turtle Emys. orbicularis, which have not completed their incubation period were transferred to indoors enclosure to finish the development. Newly hatched turtles were monitored regarding to the body weight and carapace sizes. During each of 24 measurements the turtles were subject to Open Field Test in order to evaluate their mobility and courage. The coefficient of repeatability...
Population of field vole in Southern Poland represents triennial cycle of numerical force. Regarding to this the free living vole population was tested in reference to two hypothesis of Carnov and Finerty (1980) and Lambin and Krebs (1991a), according to which the cyclic changes of sizes in population were dependent on changes of their inter individual genetic relationship. In 1999-2001 when phases...
In order to identify the possible mutations in exon 5 RPE65 gene in the Polish population of French sheepdogs - briards - we have studied 51 dogs of this breed (26 males and 25 females). The population studied consisted of about 80% of the key breeding stock animals in Poland. PCR reaction was performed after isolation of genomic DNA. The resulted product was - with no exception - of 107bp length,...
A total of 358 incubating embryos and 575 chicks produced by 36 Japanese quail parental pairs were used to determine the effect of temperature applied during short-term storage on uniformity of embryo development after 24 h of incubation and on hatchability. Embryos from eggs laid during the night reached at average the higher level of development (4.81 points) than from day deposited eggs (4.34 points),...
Longevity is the main functional trait, very important in the conservation and restitution breeding programs. This trait is determined by both genetic and environmental effects. The objective of this study was to estimate genetic variance of longevity in leopard and snow leopard populations kept in the zoological gardens. The data were extracted from the International Species Information System (ISIS)...
The Hucul horses, native breed of Carpathians, are valued for their strongly consolidated features, like high fertility, fecundity and foaling rate. The relation between the inbred and the reproduction results of Hucul mares was analyzed using two-way ANOVA and one-way ANOVA with regression. The inbreeding level is negatively correlated with fertility and fecundity. Increase of inbred level of 1%...
The behaviour of a pack of 14 Siberian huskies dogs of different sex and ages was observed. Based on observation of different dominant, submissive and affiliate behaviours of each dog, pack hierarchy was described. Behavioural patterns and frequencies of different behaviours were compared with those, previously described in wild wolves. Social structure and linear hierarchy proved very similar, whereas...
Keeping two groups of macropodid marsupials in adjacent enclosures at Warsaw ZOO created an opportunity to compare their behavior. Red kangaroo (Macropus rufus) and red-necked wallaby (Macropus rufogriseus) are two species common in zoological gardens which in the wild are crepuscular and nocturnal. The observations were carried out in November 2006 - July 2007 period. They lasted for 14 days and...
