The House Sparrow is Homeless: A Small Attempt to Conservation

Anandan G, Kumaresan M, Thomas A, Benickson C, Devi RC, Geethu M, Augustine J, Kavipriya J, Mithun Raj M and Shiva R

House sparrow is one of the endangering species of recent times. It has various roles to play in the urban environment and also helps to keep the ecological balance. The reasons for its declining are many such as lack of nesting places, lack of food and unwillingness of common man to coexist with it etc. On the whole it is an alarm bell to all to take necessary steps to conserve the small bird. In our college we have taken an initiative step by setting Nest pot in various locations where sparrows noticed and places where chance nesting is positive. We have installed more than 100 nest pot in and around found campuses of the Rover Education Institutions. And we have spread some grains purchased from the markets as a source of food for the sparrows. Our Agricultural department also requested to use organic pesticide rather than broad spectrum insecticides. We see movement of House sparrow here and there near the nest pots.

Phyto-diversity Study with Special Reference to Herbaceous Medicinal Plants

Patel DK

Chhattisgarh is rich center of Biodiversity also known as an Herbal state in India. Among the diversity of species, Medicinal plants diversity is of great importance. The state is covered with 44.00% area by forest cover. Traditional medicinal plants are used by local people to cure many diseases over the state. The plant resources are a remarkable natural source for providing many useful products. Medicinal plants diversity with special references to herbaceous plants was assessed and documented in this study. Information on Medicinal plants was recorded by surveying the area during July 2010 to June 2011. Based on the field survey there are 116 Medicinal plants belonging to 43 families were documented in and around area of Bilaspur (C. G.). Leaf is recorded as maximum used plant parts, Seed is shown as a main source to multiply the plants and the data are discussed furthermore.

Seasonal Variation of Algae Types, Counts and Their Effect on Purified Water Quality Case Study: Al-Mogran and Burri Plants, Khartoum State,Sudan

Kheiralla KM, Aatiga Eshag, Elzien SM, Saud SA and Al-Imam OA

The aim of this paper was to study the seasonal variations of algae types, counts and their effects on the quality of purified water in Al-Mogran and Burri plants in Khartoum State, Sudan, during the year 2011. In the last few years the increase of algae bloom in the Nile made big complaints from consumers and researchers in addition to their effects on the steps of water purification at Al-Mogran and Burri plants. The research methodologies consisted mainly of laboratory analysis. All the laboratory works were conducted at the central laboratories of Khartoum State Water Corporation (KSWC). Around 197 and 193 water samples were taken from the purified water at Al-Mogran and Burri plants respectively. Algae type, counts and species identification in addition to the physiochemical parameters (pH, Total Alkalinity, Turbidity) were conducted according to the Standard Methods of Examination of Water and Waste Water. The results of algae types, counts of the samples collected from both plants (Al-Mogran and Burri) showed seasonal variations. At Al-Mogran plant the green algae were dominating in the summer and autumn seasons, while the blue green registered the highest count in winter season and diatoms appear mostly in autumn. At Burri plant the green algae and blue green were registered the highest count in summer season and the winter season for the diatoms. The green algae also showed high count in rainy season comparing with other types. With respect to physiological parameters results, the highest turbidity value was noticed in autumn, pH and T. Alkalinity in summer for both plants. The study concluded that there was a seasonal variation of algae types, counts and that mostly depending on the pH value, clarity of water, sun light transmission, amount of nutrients and the nature of water. Also the algae distribution patterns were remained similar since 1970 but the quantity of algae increased.
