Abstract

We conducted research on diversity indexes in different habitats of the water beetles (Coleoptera) in forest habitats, agricultural landscapes, and freshwater habitats including ponds and streams from 20 sample collection locations in Bac Kan, Lao Cai, Cao Bang, Ninh Binh and Ha Tinh provinces. Research results show that a total of 35 species belonging to 23 genera of 4 families of water beetles (Coleoptera) have been recorded. The Shannon_H index, Simpson (1-D) index, and Berger-Parker index differed among studied provinces and were highest in Lao Cai province and the lowest in Bac Kan province. The Dominance_D, Simpson_1-D, Shannon_H, Evenness_e^H/S, Brillouin, Menhinick, Margalef, Equitability_J, Fisher_alpha, Berger-Parker, Chao-1 index also differed among at 20 sample collection locations from NB1 to VQ4. The evenness of the water beetles (Coleoptera) was divided into 4 different main groups for 20 sample collection locations. The Shannon_H index, Simpson (1-D) index, species richness and individual rarefaction were higher in forest habitats than in agricultural landscapes. However, this species richness was no different in freshwater habitats including ponds and streams

Conclusion

At 20 sample collection locations in Bac Kan, Lao Cai, Cao Bang, Ninh Binh, and Ha Tinh provinces were collecteda total of 542 individuals of water beetles (Coleoptera) representing 35 species of 23 genera of 4 families. The most diverse Coleopteran family were the family Dytiscidae with 16 species (46% of the total species). The Dominance_D, Simpson_1-D, Shannon_H, Evenness_e^H/S, Brillouin, Menhinick, Margalef, Equitability_J, Fisher_alpha, Berger-Parker, Chao-1 index differed among 20 sample collection locations from NB1 to VQ4, and high diversity at Lao Cai, Cao Bang and Vu Quang. Evenness distance (Evenness index) in different sample collection locations (NB1– VQ4) was divided into 4 different main groups The Dominance_D, Simpson_1-D, Shannon_H, Evenness_e^H/S, Brillouin, Menhinick, Margalef, Equitability_J, Fisher_alpha, Berger-Parker, Chao-1 index differed among agricultural landscapes and forest habitats, between pond and stream. In the Shannon_H index,Simpson_1-D index, the species richness were higher in forest habitats than in agricultural landscapes. However, this species richness was no different in ponds and streams. The individual rarefaction of water beetles (Coleoptera) was significantly higher in forest habitats and streams than in agricultural landscapes and ponds
