Anthropogenic disturbances can change environmental characteristics at different scales. Beetles are good indicators of various kinds of disturbances such as habitat fragmentation, edge of habitat, urbanization, climate change and pollution and also show fluctuation in their diversity according to the disturbance. Mainly dung beetle species are used for the study of forest edge. Due to their comparative facility of collection and identification, ground beetles are studied for urbanization effect. Many studies suggest an increasing beetle abundance with an increasing degree of disturbance, while the species richness, species evenness, and the diversity were found to decrease. Throughout fragmentation researches, habitat fragmentation effect was mainly observed in forests. Plummeted species richness, abundance and evenness of beetles was observed in isolated and smaller forest fragments. Small forest fragments house generalist species abundantly while large forest fragments are favoured by forest specialist species. Some species are very sensitive to edge and pollution, and also have threat to extinction, so conservation of such species is also necessary. The present study is based upon more than 40 worldwide publications from 2005 to 2021. In this study, we review the anthropogenic effects only on dung and ground beetles, as there is no sufficient study on other beetles (coleoptera). In India very limited research has been done on anthropogenic effect on beetles’ diversity. Finally, we propose further research to help us better understand the effect of anthropogenic impact on beetle diversity.
