They were active mainly during daylight hours in summer and monsoon and also less active during winter when Prunus sp., a principal winter food was scarce. On the basis of 1513 readings, the activity time observed to undergo seasonal variations was 54.3% in summer, 31.4 % in monsoon and 14.3% in winter. The percentage of maximum activity was for digging (22.7%), followed by moving (11.9%), feeding (11.8%) and resting (3.4%).The day time activity was maximum in the afternoon (1501-1800 hours), followed b y morning and evening. They were seen maximum times (59%) within 0 to 500 m from water sources. The percent sighting of bears was 27.7% within 501 to 1000 m from the water souces, followed by 13.3% within 1001-1500 m respectively. This study of activity pattern of brown bear was first time in India, which study was very important to fill ...

Sufficient work has not been done on the ichthyofaunal diversity from this estuary. The ichthy of aunal diversity sample swere collected usingd ifferentty pesofnets with the help of the local fishermenat monthly in terval of time. There were 89 fish species observed under 40 families. The family Clupeidae was dominated contributing 30.8% followed by Sciaenidae (21.7%), Mugilidae (18.5%), Ariidae (15.4%), Carangidae (10.4%) at Dhamra estuarine, north of Gahirmatha coast. Where the percentage varied toward the south of Gahirmatha coast (Hansua). Dominance diversity index value was highest in Dhamra and lowest value was in Hansua. If we compare the temporal variation of dominance of fish species status in two estuary did not fluctuate for a greater magnitude.

Observations were made on the occurrence, abundance and food habits of avifauna in coastal area Ganjam, Odisha. Surveys were conducted during April 2012 to October 2014. A total of 76 species of coastal area birds of 61 genera and 31 families were recorded. The occurrence, ecological status and food habitat of different species of coastal area avifaunal was recorded. Of all the families, Scolopacidae (12), Ardeidae (9), Accipitridae (7), Rallidae and Anatidae (5 species each), Sturnidae and Corvidae (3 species each), Alcedinidae, Aves, Ciconiidae, Cuculidae, Jacanidae, Laridae, Phasianidae and Threskiornithidae (2 species each), Anhingidae, Bucerotidae, Cerylidae, Charadriidae, Coraciidae, Dicruridae, Halcyonidae, Megalaimidae, Meropidae, Passeridae, Phalacrocoracidae, Podicipedidae, Psittacidae, Recurvirostridae, Sternidae and Upupidae (1 species each). It is expected that this study would provide a preliminary database for the coastal birds of this area force the further research.

Sacred groves are distributed over a wide ecosystem and help in the conservation of rare and endemic species. Well preserved sites are store houses of biological, ecological, medicinal, ethno-cultural and religious values. We documented the state of 13 Sacred Groves in Balasore, Odisha during March 2011. For a detailed investigation, sample areas were set, for the assessment of floral and faunal diversity, ethno-cultural values and management status. A total of 58 floral species and 13 faunal species were recorded. In Balasore, Sacred Groves are small in size and can act as starting points for any long term conservation plan of biodiversity. The communities have kept their faith and traditions linked to these mini nuclei of rich biodiversity in the landscape. Therefore, any conservation program can begin from local communities, by taking them into consi...

It is rare and usually encountered between 2800m to 4800m elevation. Population of brown bear is largely confined to the western and northwestern Himalayan regions in India and distributed mainly in the states of Jammu and Kashmir, Himachal Pradesh, Uttaranchal and Sikkim. Schaller (1969) stated that the Himalayan brown bear is largely confined to rolling uplands and high forests of fur-spruce and alpine pastures.Due to increasing human population, expansion of agricultural land, livestock grazing pressure and collection of medicinal plants, both brown bear and black bear populations are disturbed and threatened. Forests, pastures and wastelands have been brought under cultivation to sustain increased demand of cereals and other food products . The unsustainable land-use patterns...
