Understanding animal responses to the action of environmental stressors is of increasing importance under changing climate regimes. Extreme ambient temperature is one of the main abiotic factors which directly influence the viability of the species, causing significant losses of biodiversity. Animals are forced to adapt, especially by changing their behaviour, as the action of stressors increases. In order to highlight some peculiarities of the animals’ behaviour in conditions of high ambient temperatures, in laboratory experiments, on white laboratory rats, Wistar line, the action of high temperature (+40 °C) was studied on their locomotor activity, orientation reaction and emotional state (anxiety), depending on the circadian rhythm of animal activity. It has been established that the thermal factor, namely the high temperature, significantly affects the behaviour of laboratory animals, inhibiting the orientation reaction, locomotion, grooming and inducing a high level of anxiety in nocturnal rats, which can be considered as a reaction of accommodation to the stress factor. The change in the circadian rhythm, namely the morning feeding of the rats (morning group) conditioned the increase of the orientation reaction and the locomotor activity, and the decrease of anxiety state in stressed animals. Thus, due to the high temperatures, and depending on the circadian rhythm, the behaviour of rats is quite complex and oriented towards adapting as quickly as possible to the new environmental conditions. |
