Influence of weather on the behaviour of reintroduced Przewalski’s horses in the Great Gobi B Strictly Protected Area (Mongolia): implications for conservation.

Abstract: Reintroduction is a common technique for re-establishing threatened species. However, the adaptation to novel habitats with distinct conditions poses a risk of failure. Weather conditions affect the behaviour of animals, and thus, their adaptation to new conditions and survival. Reintroduced Przewalski's horses living in Mongolia's continental arid climate with extreme temperature and precipitation variability, serve as an ideal model species for studying the behavioural response of selected groups to these harsh conditions. Methods: The research was conducted in The Great Gobi B Strictly Protected Area, Mongolia. In summer 2018, three groups were recorded (Azaa, Tsetsen and Mares18) involving 29 individuals. In Spring 2019, 4 groups were recorded (Azaa, Tsetsen, Hustai1 and Mares19) involving 34 individuals. In Autumn 2019, 4 groups were recorded (Azaa, Tsetsen, Hustai2 and Tanan) involving 35 individuals. Thirteen weather variables were recorded in 10-min intervals, together with the percentage representation of selected behavioural categories (feeding, locomotion, resting, and social). The effect of weather on behaviour was analysed through GLMM. Influence of the group-history factors (recently reintroduced, long-term reintroduced and wild-born) was also analysed. Results: Feeding significantly increased with cloudy and windy conditions and was more frequent in autumn than spring and summer. Locomotion was positively explained by temperature and cloudiness and was higher in summer than spring and autumn. Resting behaviour decreased with altitude and cloudiness, and the dispersion of the group was lower when resting. Increased social interactions were observed with higher temperatures and were more frequent in summer compared to spring and autumn. Differences were found in the display of the behaviours among the selected harems, showing interesting patterns when grouping them according to their origin and experience. Conclusions: Weather patterns seem to influence the behaviour of Przewalski's horse. These results might assist in further management plans for the species, especially in the view of intensifying climate change and alteration of weather patterns. As previously suggested, after approximately 1 year, horses adapt to novel conditions and display the typical behavioural pattern of wild-born Przewalski's horses.

The research study investigates the influence of weather on the behaviour of reintroduced Przewalski’s horses in Mongolia, finding that specific weather conditions and seasons stimulate different behavioural responses in different horse groups, which may affect their survival and adaptation to new habitats.

Research Location and Methodology

  • The research was carried out in the Great Gobi B Strictly Protected Area of Mongolia on the reintroduced Przewalski’s horses during three different seasons: summer 2018, spring 2019, and autumn 2019. The study focused on different groups of horses at each stage; – Azaa, Tsetsen, and Mares18 in summer; Azaa, Tsetsen, Hustai1 and Mares19 in spring; and Azaa, Tsetsen, Hustai2 and Tanan in autumn.
  • The researchers studied the behaviour of the horses as affected by different weather conditions. Thirteen weather variables were recorded (temperature, wind speed, cloudiness, precipitation, etc.), along with the horses’ behaviours, which were categorized into feeding, locomotion, resting, and social.
  • The effect of weather on behaviour was then analysed using Generalized Linear Mixed Models (GLMM). Furthermore, the researchers also studied the influence of the group-history factors (whether the horses were recently reintroduced, long-term reintroduced, or wild-born) on their behaviours.

Research Results

  • The results show that feeding behaviour in the horses significantly increased during cloudy and windy conditions and was more frequent in autumn than in summer and spring.
  • Locomotion was positively affected by temperature and cloudiness, and was higher in summer than in spring and autumn.
  • Resting behaviour decreased with increasing altitude and cloudiness, and the horses tended to stay together more closely when resting.
  • Social interactions increased with higher temperatures, and were more frequent in summer as compared to spring and autumn.
  • There were differences in behaviours displayed among the different groups of horses, which revealed interesting patterns when the groups were classified according to their origin and experience.

Conclusions and Implications for Conservation

  • The study concludes that weather patterns have a significant influence on the behaviour of the Przewalski’s horses. As such, these findings could be crucial for designing future management plans for reintroducing the horses, especially considering the changes in weather patterns due to climate change.
  • The study also suggests that horses usually adapt to new conditions and display the typical behaviour patterns of wild-born Przewalski’s horses after approximately one year of reintroduction. This understanding can be useful to predict and ensure the successful adaptation of reintroduced species in new habitats.
