Inter-species differences in novel object test in callitrichid monkeys
ALBRECHT LIŠKOVÁ, Romana
The main subject of this study was to record the latency of the five species of monkey?s family Callitrichidae in the test with a new object and subsequently evaluate whether the response varies depending on the species, sex, location and type of subject. The observations were focused on the following species: Cotton-top tamarin (Saguinus oedipus), Golden-handed tamarin (Saguinus midas), Saddle-back tamarin (Saguinus fuscicollis), Common marmoset (Callithrix jacchus), Geoffroy's Tufted ? ear marmoset (Callithrix geoffroyi). The method used was direct observation. The time limit for the execution of each test was 20 minutes, during which it was examined whether any of the individuals approached the subject matter and whether there was any contact.
Comparative foraging study of selected species family Cebidea - "nails monkeys" in the ZOO Plzeň.
BROŽOVÁ, Alena
The main objective of this study was investigation of accurate diet portions and observing food preferences of callitrichids. The work was executed in the Pilsen ZOO in 40 days between March 2010 and September 2010. The studied species were: Leontopithecus chrysomelas, Saguinus imperator, Saguinus oedipus, Callithrix jacchus, Saguinus midas and Saguinus fuscicollis. The aim was to find out the actual nutrition values of the diet and to determine preferences for given fruits. The results were compared with recommended values. The amount of fat, proteins, fiber, calcium and phosphorus in the diet of callitrichids were compared with the recommended quantities of diet. Little diferences from recommended nutrition values were found in some cases without major impact on the animal health. The second part of the research was focused on the food preferences for five types of fruit. The results show that callitrichids prefer grapes and banana.
