Abstract
The Temporal and Spatial dispersal of copepods were studied from October 2012 to August 2013 at Jallo lake wildlife park, Lahore. Water samples were collected in the last week of every month. A total of ten species belonging to seven orders, including nauplius larvae, were identified. The physicochemical parameters were observed, i.e., water and air temperature, oxygen saturation, pH, transparency, dissolved oxygen and conductivity. ANOVA was applied to all the physicochemical parameters. It and was found to be highly significant for all parameters (P= 0.000, α = 0.05) except for the transparency. Copepod diversity and density was at its peak in June. Pearson correlation was applied between the physicochemical parameters and copepods. Air temperature (0.835), water temperature (0.729), and conductivity (0.840) were positively correlated, whereas dissolved oxygen (-0.759), oxygen saturation (-0.725), transparency (-0.401), and pH (-0.471) were negatively correlated. The quantity of the Shannon Weaver index and Simpson index was studied and calculated every month, showing fluctuations during the study period.
