Calculation of biodiversity parameters of epigean Hexapoda species in different anise (Pimpinella anisum L.) and fennel (Foeniculum vulgare Mill.) agro-ecosystems in Burdur Province

This study was carried out to compare the biodiversity parameters of epigean insect species in 3 different regions with different geographical conditions. Tefenni Plain, Beyköy (Abdülmelik) Plain and Çaylı Mountain Village, which are located at 3 different altitudes, were chosen as the study area. Pitfall traps were placed in agro-ecosystems of anise and fennel in each region and epigean insect species caught with pitfall traps were checked weekly. A total of 2086 individuals belonging to 117 epigean insect species, mostly from the carabid family, were sampled. The highest number of individuals were sampled in Tf and Ta with 841 and 440, respectively. The results of Shannon-Wiener diversity were found to be the highest in Ta with 2.7893 while the lowest was found in Ca with 2.1775. Similar to Shannon-Wiener diversity results, Simpson diversity results were calculated as highest in Ta with 0.9196 and lowest in Ca with 0.7813. Simpson's dominance results determined that Ca was the highest dominant agro-ecosystem with 0.2187. The second and third most dominant agro-ecosystems were found to be Tf and Cf with 0.1847, 0.1635, respectively. According to both Shannon and Simpson Evenness; the population densities of epigean species living in Bf and Ba were found to be more balanced than in other agro-ecosystems. The percentage similarity analysis shows that the regions selected in different altitudes were more similar to each other than the plants of the same species. Contrary to expectations, it was observed that epigean insect species did not show distribution according to plant pattern and were not directly related to plants. It is thought that the epigean insect species sampled are affected by the altitude difference
