| 1 | Ecological studies in relation to the mangrove environment along the Goa coast, India The ecology of mangroves along the Goa coast, India as compared to other regions along the Indian coast was studied. The physical parameters, structure and composition of mangroves, mangrove ecosystems, distribution of organic matter, effects of petroleum products and pesticides on mangrove seedlings, utilization and management of mangroves of Goa coast were analysed. It revealed that due to constant human pressure such as the indiscriminate cutting of mangroves, reclamation for agriculture and fish farming, overgrazing by domestic cattle have severely degraded the mangroves along the Goa coast. Proper management and better utilization of the mangrove ecosystem along the Goa coast is recommended Source: Jagtap, T.G. 1985; 212; pp. 0245. | ||
| 2 | Studies on the associate flora in the mangrove environment of Goa, India Ecological observations have been made on marine algae and seagrasses from the mangrove environment of Goa, India. Plant samples along with thallus and rhizoides were collected from nine stations; viz. Mandovi (M1-M3), Zuari (Z1-Z3) and Terekhol (T1-T3) in every month. These samples were washed thoroughly and presented in 4% formalin for further identification. A total of 44 species of marine algae belonging to 30 genera have been reported. The distribution of these species was very seasonal. The seagrass species Halophila beccarii was observed to be associated in the mangrove environment of Goa Source: Jagtap, T.G.

| 3 | Algae associated with mangroves The algae associated with mangroves is described. Substrate plays very important role in algal establishment in intertidal and subtidal areas. Algae colonising the mud surface are seasonal because of the unstable conditions caused by the erosion and accretion. Mud surface harbours unicellular algae. Multicellular algae was dominated by blue-green form on the mud surface. The benthic algae of the mud surface are represented by the green filamentous Enteromorpha clathrate, Rhizoclonium sp. and thalloid Monostroma sp. etc. These algae were found to be growing in extreme conditions in the salinity range from 30-40 ppt, temperature and nutrients and high light intensity. Sometimes due to the strong cyclonic winds, algae growing in the nearby rocky area are uprooted and enter the mangrove area. The epiphytic algal flora on mangrove trunks, pneumatophores, stilt roots, upper branches and canopies are comparatively poor. With regard to biotic factors there are a number of animals grazing on mangrove associated algal species. Mangrove habitat as a whole is unfavourable for the growth of algal species because of the lack of stable substrate, high turbidity and physiological stress Source: Dhargalkar, V.K.

| 4 | Studies on the associated flora in the mangrove environment of Mithbav Creek The study of associated flora in the mangrove environment was conducted at Mithbav creek, Maharashtra, India (Lat. 16 degrees 20 minutes N, Long. 73 degrees 25 minutes E) in October 1996 to September 1997 for the first time. The major algae recorded were Chlorophyta, Phaeophyta, Rhodophyta, Cyanophyta and Seagrasses. A total 29 species of marine algae belonging to 24 genera and two species of grasses have been reported from the mangrove swamps of Mithbav Creek. Source: Yeragi, S.S.; Yeragi, S.G.
