Species Diversity in the Himalayan Range
The Himalayan range stands out as a hotspot of biodiversity due to its unique geographical and climatic characteristics. The most appropriate reason for its rich species diversity is its position as a confluence of different biogeographical zones.
Geographical Confluence
- The Himalayas connect various biogeographical realms, including the Indo-Malayan, Palearctic, and Tibetan zones.
- This convergence allows for a mix of flora and fauna that would not typically coexist in isolated regions.
Elevation Variation
- The range spans a vast altitude gradient, resulting in diverse climatic conditions.
- Different elevations host distinct ecosystems, from tropical forests at lower altitudes to alpine meadows at higher elevations.
Microclimates
- The topography creates numerous microclimates, enabling a variety of species to thrive.
- These localized conditions support unique plant and animal communities adapted to specific environmental factors.
Isolation and Endemism
- The geographical barriers formed by the mountains lead to isolation of species, fostering endemism.
- Many species have evolved uniquely in these isolated environments, adding to overall biodiversity.
Human Impact
- While human interference exists, many parts of the Himalayas remain relatively untouched, preserving natural habitats.
- Less human encroachment in certain areas allows for the survival of diverse species.
In summary, option 'B' illustrates the primary reason behind the rich biodiversity in the Himalayan range—its role as a meeting point for different biogeographical zones, which fosters a unique and diverse array of species.
