The Himalayan range is very rich in species diversity. Which one among...
The rich species diversity in the Himalayan range is due to the confluence of different bio-geographical zones. This can be explained as follows:
Confluence of Different Bio-geographical Zones:
The Himalayas are a vast mountain range that stretches across several countries, including India, Nepal, Bhutan, and China. This region is unique as it is a confluence of different bio-geographical zones, including the Palaearctic, Indo-Malayan, and Afro-tropical regions. These zones represent distinct climatic and ecological conditions that support a variety of flora and fauna. The Palaearctic region, for example, is characterized by cold and dry conditions, while the Indo-Malayan region is characterized by warm and humid conditions. The Afro-tropical region, on the other hand, is characterized by hot and moist conditions. The overlap of these zones creates a diverse range of habitats that support a rich variety of species.
Other Factors:
While the confluence of different bio-geographical zones is the most important reason for the rich species diversity in the Himalayan range, other factors also play a role. For example, the high rainfall in some parts of the region supports luxuriant vegetative growth, which in turn provides habitat and food for a variety of species. Human interference is also relatively low in many parts of the Himalayas, which allows natural ecosystems to thrive without disturbance. However, the absence of exotic and invasive species in this region cannot be considered a significant factor as there are several invasive species that have been introduced in some parts of the Himalayas.
In conclusion, the confluence of different bio-geographical zones is the primary reason for the rich species diversity in the Himalayan range. This unique region provides a range of habitats that support a variety of flora and fauna, making it one of the most biodiverse regions in the world.
