A comprehensive assessment of habitats for amphibian fauna in Taluka Larkana, district Larkana, Sindh-Pakistan

Abstract

The present study aimed to analyze water quality of amphibian habitats via physico-chemical parameters in Taluka Larkana of Sindh Province from March to October in year: 2011, 2012 and 2013. All 26 permanent habitats of amphibian fauna were selected for analytical study using material and methods of analytical grade. Value of analyzed parameters was recorded as followed; pH: 7.8±0.8, EC μS cm-1: 2563.9±935.2, TDS mg L-1: 1770.7±511.0, T-Hard mg L-1: 555.8±123.8, T-Alk mg L-1: 284.4±65.9, Cl mg L-1: 446.3±79.2, SO4 mg L-1: 74.1±97.2, PO4 mg L-1: 476.8±82.0, NO2 mg L-1: 4.4±1.8, NO3 mg L-1: 6.7±2.1, CO2 mg L-1: 17.0±3.5 and K mg L-1: 73.8±10.0. All the water quality parameters were concentrated above the dreadful level in entire study area especially during breeding and hatching period. This unsuitable environmental condition may deteriorate amphibian population at large; therefore wild habitats in study area require urgent execution of management plans for the conservation of amphibian fauna.
