UPSC Syllabus Topic: GS Paper3- ecology, and environment

Context: A study found that seasonal conditions and captivity increase parasitic infections in zoo animals. Researchers found infections highest during monsoon and suggested regular deworming, cleaning, and proper waste disposal to control infections.

What was the focus of the study?

The study focused on seasonal climatic conditions and captivity’s role in parasitic infections among zoo animals. Researchers aimed to record seasonal worm burden and evaluate deworming protocols in two Pune zoos: Rajiv Gandhi Zoological Park and Nisargakavi Bahinabai Chaudhary Zoo.

What were the major findings of this study?

1. Seasonal Variation: Parasitic infections varied by season, with the highest incidence in the monsoon (29.50% in mammals) and lowest in summer (8.40% in mammals).
2. Bird Infections: Birds had a prevalence rate of 21.80% in monsoon, 20.00% in winter, and 18.80% in summer.
3. Environmental Factors: High humidity and suitable temperatures in the monsoon increased parasite survival.
4. Control Measures: Appropriate control methods, such as regular examination, deworming treatments, cleaning premises, and proper waste disposal, can minimize infections.
5. Data Collection: Researchers collected 450 fecal samples from 150 wild animals, including mammals, birds, and reptiles, across three seasons in two Pune zoos.

Question for practice:

Discuss the impact of seasonal climatic conditions on parasitic infections among zoo animals.
