Abstract: Phytoremediation is an emerging, ecofriendly and economically feasible technique for the restoration of heavy metals contaminated environment. In the present investigation, five native macrophytes growing naturally in a drain receiving tannery effluent viz Bacopa monnieri, Eichhornia crassipes, Hydrilla verticillate, Ipomoea aquatica and Marsilea minuta were evaluated for their heavy metal (Cr, Cu, Ni and Pb) accumulation potential in field conditions at Unnao, U. P., India. The results showed that metal accumulation by these macrophytes differed among species and tissue parts. The concentration of Cr, Cu, Ni and Pb in the root tissues were estimated in the range 3.38-45.59, 1.01-16.85, 1.81-4.43 and 1.02-4.24 ?g g-1 d wt., whereas the corresponding shoot values were 8.79 - 48.81, 1.01-8.67, 0.84-2.89 and 1.02-2.84 for Cr, Cu, Ni and Pb respectively. Among the studied plants the translocation factor (TF) ranged between 1.07-2.60, 0.75-3.83, 1.44 - 2.57 and 0.49-3.76 for Cr, Cu, Ni and Pb, respectively. The highest metal TF was found in M. minuta (2.60, 3.83 and 2.57) for Cr, Cu and Ni respectively, whereas Pb was best translocated (3.76) by B. monnieri. Roots and shoots of the studied macrophytes showed a value of greater than 1 for metal enrichment coefficient. Findings suggest that E. crassipes can be used for phytoremediation of Cu and Ni whereas M. minuta and H. verticillata can be applied for the removal of Cr and Pb respectively from the contaminated water bodies.

Abstract: Polychaete assemblages are relatively poorly known in comparison to other components from Indian waters. In the present study, the spatial and seasonal distributions of polychaetes were investigated in the Thondi coastal area. Polychaete assemblage structure seems to be inflenced by environmental parameters, such as temperature, salinity, pH, dissolved oxygen and total organic carbon. A total of 34 polychaete species were found, of which 26 species were in station I while 22 species in station II. There were a pronounced variation in diversity of polychaetes between the studied sites. Among the families maximum percentage of species constituted by Glyceridae (12%) and minimum Owenidae (4%) at station I and in station II, the Eunicidae (14%) was maximum and Pisinidae as (4%) minimum. The population density varied from 1456 to 2456 no m-2 in station I; 2120 to 4424 in station II and diversity index varied from 1.96 to 2.48 in station I; 2.01 to 2.53 in station II. Species richness varied from 1.21 to 1.65 in station II and evenness index varied from 0.9 to 0.97 in station 1; 0.91 to 0.98 in station II. BIO-ENV analysis showed that salinity, TOC and temperature as the key variables in influencing the faunal distribution.

Abstract: Studies on natural and anthropogenic radioactivity assume greater importance in the context of human health and development. Hence two species of seaweeds viz: Gracilaria edulis and Ulva lactuca, from three high background radiation areas (Arockiapuram, kadiapattinam and Kurumpana) on the southwest coast of Tamil Nadu, and Mandapam as low background radiation area of the southeast coast of Tamil Nadu were studied for variations in activity concentration of 228Ra, 40K, 238U and 228Th. Among these radionuclides,40 K recorded significant inter-species variation while 238U and 228Th showed significant association. The overall mean concentration of radionuclides was found high in G. edulis (5.31, 57.49, 36.05, 356.55 Bq Kg-1 for 228Ra, 40K, 238U,228Th respectively. The mean concentration of radionuclides was uniformly found low during northeast monsoon season in both the seaweed species.

Abstract: The oceanographic conditions of west and east coasts of India provide variations in ecological conditions. Hence, the present study was undertaken to assess the geographic distribution and diversity of foraminifera (Protista) of west and east Coasts of India to gain insights in to ecological conditions that effect their distribution. The intertidal sediment samples, collected for a period of two years from October 2004 to September 2006 were analysed for foraminiferal diversity and sediment characteristics by standard methods. Relatively high densities (west coast-156 to 19,400 g-1, east coast-37-214 g-1) and diversities were observed at all the sites of the West (74 species) compared to the east coast (57 species) Thirty three species were common to both the coasts. Forty one and 24 species were found to be unique to west and east coast, respectively. Foraminifera of west and east coasts form distinct clusters as revealed by Bray-Curtis cluster analysis, indicating distinctly different formainiferal assemblages. The geographical and oceanographic conditions thus seem to influence a differential diversity of forams.

Keywords: Crude oil, phytoremediation, Cyperus rotundus
Abstract: The aim of this study was to evaluate the efficacy of Cyperus rotundus (nut grass), that could be effective in phytoremediaton of crude oil contaminated soil. A net house experiment was conducted with different concentrations (2.05, 4.08, 6.1, 8.15 and 10.2%) of crude oil-contaminated soil for 180 days. Plant growth, biomass, total oil and grease (TOG) degradation and microbial numbers wree analyzed at different intervals i.e. 60, 120 and 180 days in different percentages of crude oil contaminated soil. In presence of crude oil, plant biomass and heights reduced up to 26 and 21.9% respectively. Concerning TOG content in soil, C. rotundus could decrease up to 50.01, 46.1, 42.6, 38.8 and 32.6% in treatment I, II, III, IV and V respectively in vegetated plots during 180 days. In case of unvegetated pots, the reductions of TOG were 4.4, 5.6, 6.6, 7.6 and 9.6% in treatment A, B, C, D and E respectively. However, there was significant degradation (P = 0.05) of TOG in vegetated pots in comparison to unvegetated pots thereby proving the efficacy of this plant species for use in phytoremediation.

Abstract: Echinochloa colona (L.) Link is a very problematic weed in up land and medium land rice causing significant reduction in yield. In the present investigation, laboratory and field experiments were conducted to evaluate the nature of interaction E. colona on germination and growth of the upland rice cultivar ' Vandana ' . The effects of decomposing and decomposed aqueous leachates (1-10% w/v) obtained from the dried biomass of 20, 30, 40 and 60 days old E. colona plants were studied on rice using petridish bioassay technique with three different types of culture media like filter paper, soil, and soil + activated charcoal. The decomposing leachates of E. colona showed strong toxic effect on root and shoot growth fo rice, the highest being noted with 10% leachates of 60 days old plant residue. It inhibited root and shoot growth by 100% and 43.9% respectively as compared to control. The corresponding decomposed leachates inhibited rice germination by 90% and root and shoot growth by 70 and 25% respectively. These toxic effects of leachates showed in filter paper medium were significantly reduced in soil and soil plus activated charcoal media proving their allelopathic nature. In a field experiment, E. colona and rice were grown in proportions of 1:1, 1:2 and 1:4, the total plant density being maintained at 100 palnts m_2. The height and dry matter of rice were adversely affected with increasing in E. colona population. From another similar field trial, data on dry mattre of 20, 30, 40 and 60 days old plants were taken and their plant relative yield (PRY) and relative yield total (RYT) values were calculated. The PRY and RYT values wre found to be less than unit (<1) throughout the growth period studied which suggested the presence of severe antagonistic interspecific interspecific interaction between rice and E. colona due to allelopathy.

Abstract: Mud crabs usually inhabit brackish bodies of South-East Asia including India. The biological significant of the species is its survibility in wide range of hydro-biological fluctuating environments including salinity. The life cycle of the species includes two importnat larval stages at which they are vulnerable to various predators. Pathophysiological status of the species is a challenge for its aquaculture. Inspite of a huge economical and high food values, informations on biochemical, molecular, physiological, ecological and taxonomical aspects of mud crabs (Scylla sp.) in comparison to other important aquaculture candidates are very limited. The present review is an attempt to string together various informations available on mud crabs (S. serrata) so that it will provide a platform to have all the basic information regarding the species for interested workers. It is believed that understanding the pathology, ecophysiology, genetics and reproduction of the species in its natural environment will nt only help in its conservation but also will help in its enhanced production.

Abstract: Calcium play an important role in various physiological processes such as nerve impulse transmissiom, muscle contraction, hormone actio, blood clotting. They ions act as an intracellular second messenger, relaying information within cells to regulate their activity. To understand the mechanism of hepatotoxicity of t-BHP, studies were carried out suing freshly isolated rat hepatocytes. The effect of t-BHP on Ca2+ accumulation and Ca2+ uptake by rat hepatocytes was monitored using 45Ca2+. It caused decrease in 15% accumulation of 45Ca2+ in comparison to the control group. t- BHP also significantly decreased the Ca2+ATPase activity in isolated hepatocytes. This decreases in Ca2+ ATPase activity by t-BHP was reversed 40% by naturally occurring antioxidant butylated hydroxy toluene (BHT). These results indicate that the hepatoxic action of t-BHP involves oxidative stress as evident by the protection accorded by various antioxidants employed in the stuy as well as impairment of intracellular calcium homeostasis which can lead to liver cell injury.

Abstract: Tea [Camellia sinensis L. (O) Kuntze] is an economically important plantation crop of India but is prone to attack by sevreal fungal pathogens. Copper based fungicides are being used for decades to control fungal diseases in tea which may lead to accumulation of copper in the soil. The biochemical responses to increasing concentration of copper (50 to 700 ?M) were investigated in the leaves of two cultivars of tea commonly grown in the Darjeeling hills. Expodure to excess Cu resulted in increased lipid peroxidation (level of TBARS increased from 3.5 ?mol g-1f. wt. in control to 12 ?mol g-1 f.wt in TS-520 plants exposed to 700 mM of Cu), reduced chlorophyll content (from 83.7? g g-1f. wt. in control to 22.5 ? g g-1f. wt. in TS-520 plants exposed to 700 mM of Cu), higher levels of phenolic compounds (total phenol content increased from 4.54 mg g-1f. wt. in control to 5.79 mg g-1 f. wt. in TS -520 plants exposed to 400 mM of Cu) and an increase in peroxidase enzyme levels. Two new peroxidase isozymes (POD 1 and POD 2) were detected in plants exposed to Cu. In addition, biochemical responses in two tested cultivars, TS - 462 and TS-520 differetn significantly. TS-520 was found to be more sensitive to increasing concentrations of Cu. Superoxide dismutase activity increased progressively from 2.55 Umg-1 protein in control to 5.59 U mg-1 protein in TS-462 but declined from 4.75 U mg-1 protein in conrol to 3.33 U mg-1 protein in TS -520 when exposed to Cu concentratons hgiher than 400 ?M. A sharp increase in the activity of ascorbate peroxidase (from 0.53 units in control to 2.37 units in plants exposed to 400 mM of Cu) was noticed at the 10th day of exposure in the more tolerant cultivar. On the other hand, catalse levels increased only marginally (from 8.4 to 10.1 units in TS 520 and 8.7 to 10.9 units in TS 462) in both the cultivars. From this study, it appears that Cu exposure led to the production of reactive oxygen species in the leaves resulting in significant lipid peroxidation. Tea plants try to mitigate this oxidative damage through accumulation of phenolic compounds and induction of antioxidant enzyme.

Abstract: Imperata grassland at Dorgakona, Barak valley, North Eastern India was analyzed for species composition and diversity pattern in relation to traditional management practices 19 families were in the burnt and unburnt plots of the study site with Poaceae as the most dominant one. 29 species occurred in the burnt plot and 28 in the unburnt plot. Most of the species were common in both the plots. The pattern of frequency diagrams indicated that the vegetation was homogeneous. Imperata cylindrica, a rhizomatous grass was the dominant species based on density (318.75 and 304.18 nos. m-2), basal cover (158.22 and 148.34 cm2 m-2) and Important value index (IVI) (132.64 and 138.74) for the burnt and unburnt plots respectively. Borreria pusilla was the co-dominant species constituting Imperata-Borreria assemblage of the studied grassland. It was observed that B. pusilla (162.25 nos. m-2 and 50.37 nos. m-2), I. cylindrica (318.75 nos. m-2 and 304.18 nos. m-2) and Setaria glauca (24.70 nos. m-2 and 16.46 nos. m-2) were benefited from burning as shown by the values sequentially placed for burnt and unburnt plots. Certain grasses like Chrysopogon aciculatus and Sacciolepis indica were restricted to burnt plot while Oxalis corniculata showed its presence to unburnt plot. Grasses dominated the grassland as revealed by their contribution to the mean percentage cover of 72% in burnt plot and 76% in unburnt plot. The dominance-diversity curves in the study site approaches a log normal series distribution suggesting that the resources are shared by the constituent species. Seasonal pattern in diversity index suggested definite influence of climatic seasonality on species diversity; rainy season was conducive for maximum diversity (1.40 and 1.38 in the burnt and unburnt plots, respectively). Dominance increased with concentration of fewer species (0.0021 in burnt plot and 0.0055 in unburnt plot) in summer and behaves inversely to index of diversity. This study showed that the traditional management practices benefits the farmers as it promote grassland regeneration with I. cylindrica as the dominant grass.

Abstract: Two species of Trichoderma i.e. T. harzianum and T. viride have been isolated from the soil samples collected from the higher altitude (2000-3500m) of Garhwal Himalayan region in India. The two species were grown in Petri plates on TSM agar media and it was also observed that the optimum temperature and pH for Trichoderma growth was 300C and 5.5 respectively. When incubated on TSM agar medium at 40C, the fungus grew normally with heavy induced sporulation within three weeks of incubation. Induction of sporulation on exposure to low temperature appeared to be strategies for survival of these species in extreme cold environment temperature 4 to 50C. Antifungal activities of the two species of Trichoderma were demonstrated with phytopathogenic fungi in dual cultures. The antifungal metabolites produced by Trichoderma spp., diffusible as well as volatile, caused abnormalities in pathogenic fungi. Plant growth promotion of Tirchoderma spp. was also shown through plant analysis in greenhouse.

Abstract: Esterase isozymic variations were documented in the haemolymph of developed multivoltine and bivoltine silkworm breeds during unfavorable seed crop seasons of May - September using -?- and ?- napthylacetate separately to identify specific and nonspecific esterase having thermotolerant potentially. Variations existed in the isozyme pattern with three bands (Est-2,3 and 4) in pure Nistari race and other developed multivoltine and bivoltine breeds. Est-2 and Est-3 were non-specific esterases as they were observed when both ? - napthylacetate as substrate and was therefore confirmed to be specific ? - esterase band in the haemolmph of silkworm, Bombyx mori L. Zymograms showed that the non-specific esterase band (Est-3) with Rf of 0.43 and specific ? - esterase band (Est-4) with Rf of 0.32 predominately withstood a temperature of 70+20C for a duration of 10 min and were confirmed as thermostable esterases in haemolymph of silkworm, Bombyx mori L. This also categorized the presence of thermostable esterases in developed multivoltine and bivoltine breeds of silkworm, even though the qualitative activity was more in the former than the latter. The qualitative presence of thermostable esterase and their activity was more in the former than the latter. The qualitative presence of thermostable esterases and their activity could be adopted as an indicative biochemical marker in relation to thermotolerance in silkworm.
