    Description: Discharge of industrial and domestic wastes in sea alter the physical and chemical properties of sea water, which may affect the marine ecosystem. This study was aimed to measure the water quality of eight different creeks around Port Qasim. Samples were collected and analyzed using standard procedures during February and March,2009. The parameters including pH, Conductivity, Total Dissolved Solids, Salinity, Dissolved Oxygen, Nitrate, Phosphate, Sulphate, Chloride, Calcium, Potassium, Zinc,Iron, Cobalt, Chromium, Manganese and Cadmium were determined. The result shows that Bakran creek and Gharo-Phitti creeks are heavily polluted compared to other creeks. This study recommends that wastes from the industries or sewerage should be treated before being discharge into the creek system.

    Description: The study deals with population diversity and seasonal variation of insectsin Sandspit mangrove forest dominated by grey mangrove Avicennia marina. In order toexamine the diversity and seasonal variations monthly data were collected fromNovember, 2007 to October, 2008. A total of 26 species of insects were recorded, mostof the species belonging to order Diptera. The highest diversity (H') 1.936 and richness(d1) 2.309 of insects were found in October while maximum value of evenness 1 wascalculated in September. The highest value of dominance (D) 0.851 was recorded inMarch. The result indicates that physical structure of mangrove vegetation facilitates thehabitation of insect fauna, canopy shade having an important function in providing coolerand wetter surface substrate at Sandspit area.
