Mammalian species distribution and diversity in arid region of Kachchh, Gujarat
Nikunj B Gajera, Mukesh Koladiya
The aim of this study is to examine the mammal’s diversity and distribution to provide information for making informed conservation decisions. We examined four different land-use land-cover or habitats categories for mammal’s diversity. Line transects for direct sightings and belt transects for indirect evidences were used to assess mammal species. For the present study the Lakhpat and Abdasa talukas and part of Nakhatrana Taluka had been identified where the major development activities are supposed to come up in the near future. Analysis of variance was used to test hypotheses and Tukey HSD Post Hoc was used to identify specific variables those differ significantly. The variables used for testing hypothesis includes number of Species, Density, Shannon diversity index, Simpson diversity index, Dominance index, Evenness index, Menhinick species richness index, Margalef species richness and Equitability index. Based on direct sightings and indirect evidences, a total of 20 mammal species belonging to 11 families and 16 genera were recorded during our survey. Eight species of herbivores, seven species of carnivores, two species of granivores and one species of each omnivores, frugivores and scavenger recorded from the study area. Five threatened mammals species were recorded, which included two cats (Panthera pardus and Felis libyca), one canid (Canislupus), one ungulate (Gazella gazella) and an insectivore (Hemiechinus auritus). ANOVA results shows that four Land cover types or habitats differ significantly in terms of Number of species, Margalef species richness, Evenness, Equitability.
