Abstract: Spiders attract special attention to the zoologist on account of their unique weaving capability of constructing webs with geometrical precision. Web weaving habit of spiders are unique because few of others insects like (silk worm) produce silk, yet the survival value of silk spinning or web weaving has never been discovered by any observers. According to their web building 'ability, generally the spiders are considered as weavers or non-weavers Present paper describes the web architecture and patterns of spiders with respect to their diversity and distribution in the habitat of Eastern Rajasthan. There are more than 30,000 documented species of spider in the world. These species can be broken in to two categories: web builders and ground dwellers. The type of web spider spins depends entirely on the spider's way of life. The pattern and architecture of webs varies family to family.

Abstract: Monitoringofriver waters arean important in now a days because of increasing industrialization, urbanization and anthropogenic actives from river banks. The industrial effluents, domestic sewage, agricultural wastesand aquacultural wastes are being discharged into the river waters and finally reaching into coastal waters that causing degradation of water quality. The present study was carried out to determine the water quality in terms of seasonal variability and behavior of physicochemical and nutrients parameters for a period of one year during 2013 in the estuarine waters of Gauthami Godavari along its longitudinal stretch at seven station from the head of the estuary to mouth of the estuary.

Abstract: A three-year study was conducted in twenty five mollusc – inhabited water bodies spread across four hydrological areas in northern Nigeria. This was done to determine some aspects of the geomorphology and limnology of the water bodies. Four sampling stations were selected along a line transect across each water body for collection of aquatic molluscs, measurement of physico-chemical factors and other parameters. A portable Combo Hanna® meter was used to measure pH, electrical conductivity, water temperature and total dissolved solids while alkalinity, sulphate, nitrate, phosphate, chloride, hardness, dissolved oxygen and biological oxygen demand were determined by titration. The specimens of freshwater molluscs collected were identified using standard procedure

Abstract: Les huiles sont considérées comme une source primordiale de matières premières recherchées en cosmétique. Pour valoriser la fabrication des produits nouveaux et sous produits locaux à bases des huiles tunisiennes et vu l'émergence du secteur de la cosmétique issue d'unités semi-industrielles, Nous avons étudié, dans ce présent travail, la caractérisation des huiles des graines de différents plantes, le laurier (Lauris nobilis), le Pen d'Alep (Pinus halepensis), et la figue de barbarie (Opuntia ficus indica) ainsi que la composition de ces huiles en acides gras. La collecte des fruits a été faite au mois de septembre et d'octobre de 2014. L'extraction des huiles a été réalisée en utilisant la technique Soxhlet et la teneur en acide gras a été déterminée par chromatographie en phase gazeuse.
