Every year, the 5th of June is observed as the World Environment Day to “encourage worldwide awareness and action to protect our environment”. For 2019, the theme is ‘Air Pollution’, and the host country is China. On this occasion, Research Matters caught up with three leading scientists from the country that are actively pursuing research on different aspects of air pollution. The three researchers, Prof. A R Ravishankara, Prof. S K Satheesh and Prof. Navakanta Bhat shared their work and thoughts on the ‘burning’ problem of air pollution.

Researchers from the Nature Conservation Foundation, explored organisation of plants and fruit-eating bird communities of the Pakke Tiger Reserve in Arunachal Pradesh. They observed 43 plant species and 48 bird species in the region, and have identified the different networks formed between the trees and their avian seed dispersers.

Bengaluru’s decreasing tree cover and expanding concrete jungle in recent decades paints a grim picture of the city’s biodiversity. The tales of sparrows nesting on the roofs, parakeets pecking on the juiciest fruit in the backyard tree or the myriad coloured butterflies dancing in the garden are now fragments of imagination! So where have all the birds, animals and insects gone?

Forests, with their rich biodiversity, play a critical role not only in the ecology of a region but also in social systems that involve humans. Researchers from the University of Illinois, USA, used artificial intelligence to evaluate the forest management policies in Himachal Pradesh, India.
