Seasonal Evolution of the Microclimate Factors Level in a Zoo

The aim of this paper was to establish the seasonal evolution of the microclimate factorslevel in several shelters from Turda Zoo. Four sets of measurements were made (in summer, autumn,winter and spring) in different places: the cage and the paddock of the baboon (Papio cynocephalus),the cage and the paddock of the lion (Panthera leo), the wolves’ (Canis lupus) shelter and at theexterior of the zoo. The following parameters were determined: temperature, relative humidity, gasesconcentration in the air (O2, NH3 and H2S), total count of aerobic mesophilic bacteria (TCAMB) andfungi. The most important finding of the summer measurements is the value of ammonia recorded inthe lion’s cage, which was 28 ppm. At the autumn measurements, the absence of H2S was noticed,while the maximum value of NH3 was 5 ppm. Temperature recorded in the baboon cage was belowthe limit of 22 °C, recommended in primates shelters. At the winter measurements a significantdifference between the temperature in the baboon cage (9.1 oC) and the exterior temperature (-6 oC)was recorded. The humidity value in the lion’s cage was higher than those recorded in the otherplaces. At the spring measurements a high value of the ammonia in the lion cage (29 ppm) was noted.Baboon cage temperature was also below the recommended limit.
