Conservation Status of the Indian Peafowl Pavo cristatus (Aves: Galliformes: Phasianidae) in Bangalore University Campus, Bengaluru, Karnataka, India
The Indian Peafowl, Pavo cristatus was abundant in Bangalore University Campus (BUC) during 1970-80. However, the peafowl population declined alarmingly in the BUC region after 1990. The present paper deals with the abundance, sex ratio of peafowls and their conservation methods in the Biodiversity Park (Bio-Park) of BUC, which had been established in 2006. A total of 117 peafowls was recorded in the BUC region in which the females outnumbered the males. The increased abundance of the peafowl population in the campus could be mainly due to the availability of suitable roosting, foraging and nesting sites. The peafowls have used 18 species of plants and trees for perching and roosting in BUC. The peafowl population increased in the BUC region due to habitat rejuvenation and protection, availability of food sources and breeding/nesting sites. The results of the present investigation constitute the baseline data for the further understanding of the ecological community of national bird in the protected habitats as hotspots for biodiversity of urban ecosystem. Conservation of microhabitats through the proper restoration of ponds, streams and water check-dams including vegetation in the BUC is responsible for the existence of peafowl population

J.Bio.Innov3(2),pp:93-102,2014 www.jbino.com DEVELOPMENT OF ABNORMAL SOMATIC EMBRYOS IN BANANA CV.
The traditional table choice elite variety of Karnataka, NanjanagudRasabale is in the verge of extinction due to the serious outbreak of panama wilt disease in the Nanjangudtaluk of Mysore district. Banana cultivar Rasthali (AAB) has been chosen to do In vitro studies on somatic embryogenesis. Embryogenic callus and somatic embryos were generated with male flower buds on MS medium supplemented with 2,4-D (18.10 μM), NAA (5.37 μM) and IAA (5.71 μM) with 3 % sucrose and 0.2 % gel rite. After 6–8 months well developed somatic embryos were sub cultured on to MS supplemented with NAA (1.07 µM), Zeatin (0.23 µM),2 ip (0.60 µM) and kinetin (0. 46 µM) for further maturation. Several morphological embryo variants have been observed which brought the germination frequency to the lesser extent. Histological and histochemical studies revealed that all the embryos making up the clump were developed asynchronously and had different patterns of development. Regardless of the stage of maturation, a large number of somatic embryos showed structural abnormalities some of which could be detected by histological observation. Different embryogenic structures were developed without passing through recognizable stages of zygotic embryogenesis. Localization of starch, total insoluble proteins and nucleic acids were observed in the somatic embryos. Evidence presented in this study points towards abnormalities which may cause somaclonal variations in the economically important plant like banana cv. Rasthali
