abstract
An analytical study was conducted for analyzing some parameters i.e. electric conductivity (EC), total dissolved solids (TDS) and total hardness (T-Hard) from amphibian habitats at District Larkana. The study conducted from March to October for three years (2011-2013) recorded all 26 amphibian habitats consisting of unfavorable values of studied parameters. The value of EC was recorded as 1180.5-7472.6 uS/cm, while concentration of TDS and T-Hard was analyzed as 788.8-4309.2 mg/L and 200.5-980.7 mg/L respectively. Maximum upsurge in value of studied parameters was recorded during breeding and hatching period of animals in question. This deplorable condition of aquatic habitats may induce negative effects on growth and development of amphibian populations of the study area and may also cause decline in their population status.
