Adequate water most important for plant diversity
Study shows how rainfall and temperature affect variety of plants in major bio-geographic zones of India Posted on 09 Jul, 2019 03:58 PM

New Delhi, July 9 (India Science Wire): India has a total geographical area of nearly 329 million hectares. The climate varies from the north to the south and east to west. However, in spite of this diversity, little is known about how climate affects the diversity of plants that grow in a particular area.
