abstract
The present studyrnanalyzes lognormal and log series distribution of meta- communities ofrnsarcosaprophagous fly species of a large area. The carrion fly species containrnnumerous individuals and analysis of their diversity is the central theme ofrnthe present study. The fly populations of three families (Parasarcophagidae,rnCalliphoridae and Muscidae) form a guild and are potentially competing in arnlocal area for common resource utilization. The sampling data of sarcosaprophagousrnfly species from twelve study sites are analyzed with logarithmic series,rnlognormal distribution, Whittaker plots as well as canonical correlationrnanalysis (CcorA) and CCA to show their relationships in distribution patternrnover a large area. The analysis of these fly species corresponds to theirrnsynanthropic association with human population. The outcome of the analysis of γ- diversity shows that therndistributions of this fly guild are not uniform; instead exhibit patchiness,rnshow wide range of variation in species richness due to possible variation inrnmicrohabitat.
