Comparison of insect biological diversity parameters in natural and degraded habitats in Gölcük Nature Park (Isparta, Turkey)

The study was carried out to compare the biodiversity parameters of the insect species in natural and un-natural habitats in Gölcük Nature Park (Isparta Province) between 2018 and 2019. Two natural and two unnatural habitats (impact of tourism) were selected to realize mentioned aim. Totally 40 pitfall traps (10 traps for each habitat) were set up to sample Coleoptera species. Species richness was found higher in natural habitats than unnatural ones. Diversity index (both Shannon-Wiener and Simpson) were calculated higher in natural habitats and as expected, dominancy inversely proportional to diversity was measured lower in natural habitats. Shannon Evenness, population density due to individual of the species showed mostly evenly distributed on the graphs in natural habitats. The Sörenson Coefficient results showed that selected natural and unnatural habitats groups were found similar to each other. The results of the study showed that human activity plays an important role in habitat destruction. It has been revealed that species richness and diversity are negatively affected in habitats with human impact.
