Biodiversity of Crabs in Karwar Mangrove Environment West Coast of India

In this study, the distribution of crabs in Karwar was recorded from October 2007 to July 2008. At monthly intervals. The species present on the subs tram and on the vegetation area were recorded in quadrant each measuring 1meter square. There are about 15 crabs species are distributed in karwar mangrove environment. Crabs belonging to the family Grapsidae and Ocypodidae are most dominant forms. Substrate suitability, effects of tidal inundation and distribution of mangrove plants were the possible factors that could influence zonaztion and abundance of the crabs in the karwar mangroves

Shadows of Time: Content creation for the Performance art installation

Shadows of Time is a non-linear narrative video installation which would be used as a backdrop for the larger performance event. The content creation for the performance was undergone a series of process to achieve the style which was decided by the team. The installation will showcase only the photographs of architectural details of Tombs which would depict symbolically the different phases of her life such as Hayat Bakshi’s timeline, her husband’s death, her thoughts about future following her death and finally showcasing the present scenario. In the process, I explored various style of image processing, methods and processes of filmmaking, different kind of treatments in order to achieve the required output as per the decided framework. The result is an eight-minute video narrative projection without dialogues along with the composed music and set design. The final installation event would be a collaboration with the performance artists along with other interactive installations contributed by other members in the team

Effect of some antibiotic compounds in Gossypium on the post‐embryonic development of spotted bollworm (Earias vittella)

The antibiotic activity of some compounds, and of plant extracts, was bioassayed by incorporating them in a wheat germ diet developed for rearing cotton spotted bollworm (Earias vittella F.). Acetone extract of square powder caused maximum mortality followed by gossypol, tannic acid, other tannins and anthocyanins. Hexane extract of bolls did not affect larval survival. Rutin, anthocyanins and ether fractions of the ethanol extract decreased % pupation of larvae while in diets containing gossypol and tannic acid, none of the larvae could reach pupal stage. Some of the larvae were unable to spin the silken cocoons when reared on diets containing gossypol, tannins, anthocyanins and rutin. Tannins and anthocyanins increased the developmental period of insects. All the compounds or solvent extracts except hexane extract of bolls decreased pupal weight. It is suggested that gossypol, tannins, anthocyanins and other secondary substances present in cotton squares and bolls could be utilized as a source of biochemical resistance against E. vittella
