• Species diversity increases towards equator. The two main reasons are phylogenetic niche conservatism and ecological productivity. 
• The relatively high temperatures in tropics generate and maintain high diversity. 
• However, tropical rainforests in developing countries are getting cleared nowadays, which is leading to a great loss of biodiversity.

Brow Antlered Deer is found in Keibul Lamjao National Park, Manipur. A park in use for conservation purposes is known as a National park. It is basically a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Flora and fauna are provided immense protection in such areas. Currently, in India, we have 166 national parks. 

Animals constitute more than 70% of all species recorded whereas plants constitute around 22% of total number of species.
