Diversity of Amphibians and Reptiles at Chiremera Locality, Vanduzi - Mozambique
Asian Journal of Biology,
Diversity of amphibians and reptiles was studied at Chiremera locality in Manica Province, Mozambique. To the best of our knowledge, no herpetofauna study has been done at the Chiremera locality. Globally the herpetofauna of Mozambique remains poorly documented compared to other areas of southern Africa . The study aims to assess the diversity of amphibians and reptiles at Chiremera locality. The data was collected using two techniques: Visual Search and Intercept and pit fall traps. The data was collected in two habitat types: wild areas and human altered areas. We recorded on the wild areas 91 individual of amphibians (18 species, 10 genera and 9 families). The human altered areas had a total of 27 individual amphibians, (4 species, 4 genera and 4 families). Hemisus marmoratus (marbled snout-burrower) was the most abundant species in the two habitats, accounting for 26.3% of all individuals identified. The Shannon winner of amphibians was higher at the wild areas (H '= 2, 1) and lower in the human altered area (H' = 1, 2). A total of 24 individual reptiles were recorded on the wild areas (7 species, 7 genera and 5 families). In contrast to human altered areas we recorded (5 species, 3 Genera, and 3 families). Bitis arietans (puff adder) was the most abundant reptile accounting for 26% of all individuals identified. The Shannon wiener of reptiles was (H’=1, 6) at the wild areas and (H’=1, 5) at the human altered areas. Four rare species namely Hyperolius acuticeps (sharp-headed long reed frog), Hyperolius benguellensis (Benguella long reed frog), Ptychadena subpunctata (spotted ridged frog) all amphibians and Naja mossambica (Mozambique spitting cobra) - reptile were detected during our study. The result of the current study revealed that effect of human altered areas on the richness and abundance of amphibians and reptiles.
