Debris from four beaches of the Great Nicobar and five beaches of Little Nicobar Islands were collected using transect based approach during March-April 2016 for assessing the status of marine debris. The collected debris were segregated into five types; plastics, fisheries, medical waste, house waste and food packaging and were analysed to estimat...

The cultivation of native ferns is still neglected in Indian horticulture or floriculture;
however, hundreds of cold hardy ferns occurring in the Indian Himalayas along with many
tropical and subtropical species are under cultivation in Europe, USA, and other countries for
more than last 250 years. Therefore, in the present article the horticultura...
The presence of Polystichum zayuense is recorded from the West Himalaya. There are
only a few reports of this little-known fern in the Indo-Himalaya. A few mostly small-sized and often confused species of this genus are also discussed with illustrations and key-characters to help in identifying them.
Pteridophytes are being used by human beings from time immemorial, but compared to flowering plants, their uses and economic potential are still neglected; therefore, they need to be highlighted and popularised. Out of ca. 1200 taxa of Indian pteridophytes, nearly 800 occur in the Himalayan region. Traditionally different ethnic groups of the Himal...
