Abstract
The experiment was condected in clay loamy soil to known the Efficacy of dairy effluent on morphological and pigment condence of black gram ( Vigna mungo.L) Hepper. The dairy effluent concentrations such as 10,25,50,75,100 percent were applied on the black gram Seedlings. The parameters such as germination percentage root length, shoot length, fresh weight and dry weight, vigour index, tolenerant index, percentage of phytotoxicity were measured. The biochemical content such as, chlorophyll a, chlorophyll b,Total chlorophyll,carotenoids contents were measured .the mineral content such as ,protein,aminoacid,Reducing sugar ,nonreducing sugar and total sugar also recorded .Highest growth performance was recorded at 10 percent Effluent concentration when compare to other treatments

Abstract
Indian mangroves cover about 6,749 km, the fourth largest mangrove area in the world. These mangrove habitats (69°E-89.5°E longitude and 7°N-23°N latitude). In India, West Bengal, Orissa, Andhra, Tamil Nadu, Andaman, Nicobar Islands, Kerala, Goa, Maharashtra, and Gujarat occupy vast area of Mangroves. The Indian mangroves comprise approximately 59 species in 41 genera and 29 families. Mangroves in India are one of the most valuable coastal habitats providing enormous benefits (both tangible and non-tangible) to the local communities as well as the ecology and environment surrounding them. But these mangroves have so many threats like Additional pressures on wetlands from natural causes like subsidence, drought, hurricanes, erosion etc., and human threats coming from over exploitation, for agriculture, commercial and residential development. Tangible benefits of mangroves comprise timber and non-timber products, fishery and other livelihood support systems whereas non-tangible benefits include ecological and social functions, such as coastal protection against wave and current abrasion, shelter and habitat for wildlife, and ecotourism. Mangroves need protections from natural disasters in which coastal zone is a dynamically unstable where of one or the other kind like sea intrusions, cyclones, tsunami, etc., Along with the restoration work, awareness should be campaigned, educational materials should be made available to improve knowledge on mangrove habitats, resources, relevant legislation, policies and conservation strategies with the help of media like magazines, posters, documentary, exhibitions, bird watching tours, study tours, competitions on mangrove knowledge etc. Learning can be easier with better.

Abstract
Marine plants are considered as a source of bioactive compounds as they are able to produce a great variety of secondary metabolites characterized by a broad spectrum of biological activities. Compounds with antioxidant, antiviral, antifungal and antimicrobial activities have been detected in mangroves, seaweeds and seagrasses. Marine plants are the source of amino acids, terpenoids, phlorotannins, steroids, phenolic compounds, halogenated ketones and alkanes and cyclic polysulphides. In this study, the antibacterial activity of flowering seagrass species viz., Syringodium isoetifolium and Cymodocea serrulata and non-flowering seaweeds viz., Amphiroa anceps, Gracilaria corticata, Sargassum wightii, Padina pavonica, Ulva lactuca, and Valaniopsis pachynema were tested. Interestingly it is found that, most of the ethanolic algal extracts controls all the pathogens of antibiotic resistant organism, fish pathogens, poultry pathogens and human ophthalmic pathogens. The antibacterial activity of halophytic plant extracts were evaluated by the well diffusion assay and the zone of inhibition ranged between 6mm to 14mm. The maximum activity was recorded with the marine algal ethanolic extract of V. pachynema against almost to all the pathogens selected for the study.

Abstract
Trichodesmium erythraeum is a filamentous cyanobacteria which forms dense algal bloom along the Pudhumadam coast in the Gulf of Mannar during the pre monsoon season 14th September, 2014. At the time of bloom totally 25 zooplankton species were observed of which four species were considered as most abundant viz. Corycaeus danae (19.28 %), Acrocalanus gracilis and Microsetella norvegica (7.23%) and Gastropod veliger (6.02%). Although the T. erythraeum occurred in high concentration (75,000/m3), it did not cause any unusual mortality to the marine large fish and shellfish and disrupt the marine environment.

Abstract
Heavy metals are integral components of ecosystem. The distinctivenesscharacteristic of heavy metal is poisoning and resulting in the inactivation of enzyme systems. All heavy metals are potentially toxic at elevated concentrations. In the present investigation, effect of Lead nitrate[Pb (NO3)2], on the morphological parameters of black gram seedlings (Vigna mungo (L.)Hepper),the germination percentage and morphological parameters such as, root length, shoot length, number of leaf, total leaf area, root nodules,fresh and dry biomass were analyzed on the 15th days of seedlings. Among the all parameters were reduced in increasing the Pb(NO3)2 concentration when compared to control plants.
