Distribution of Anuran Parasite and Water Quality Indices at Putrajaya Lake and Wetland

The anuran population in an ecosystem is a good indicator of the cleanliness of the environment. A low anuran population or a high anuran mortality rate in an environment indicates that the ecosystem of the surrounding area is unstable, such as exposure to polluted water or high parasite distribution. The objective of this study was to determine the diversity of anuran species, the distribution of anuran parasites in Putrajaya lake and Wetland Putrajaya, and the relationship between water quality index with the distribution of parasites and anuran. A total of 74 frogs were caught during the sampling period, representing five families and six anuran species. According to the Shannon diversity indices, sampling stations LE, UN, UW, P.7, and P.10 had a diversity index value of 1.3 indicating that the diversity of anuran species was moderate. A total of 2437 parasites were identified from 74 dissected frogs in this study. Parasites have infected an estimated 86.5% of frogs in the Putrajaya area. The water quality index status for all Putrajaya stations is considered clean to moderately clean (Class II to III). The Kruskal-Wallis test showed that the parasite distribution on the anurans at each station UE, UW, UN, LE, CW, P.7 and P.10 was not significant (X-2 =9.28; df=6; p> 0.05). This means that there is no significant difference in the distribution of parasites on the anurans in each area, and the infection of these parasites is unaffected by the water quality indices at the sampling stations.
