Özet:

This study was conducted with the aim of evaluating the biodiversity parameters of epigean species in the mandarin agro-ecosystems where different applications were carried out between 2019 and 2022. As a study area, the University of Çukurova, Ziraat Faculty has selected 50 hectares of Mayer lemon garden located within the boundaries of the Döner Capital Business. Four parcels are set in the garden to this goal. These are (i) chemical (herbicide is periodically applied for foreign herbicide control and foreign herbicide is not allowed to grow), (ii) foreign herbicide cutting (in-line cutting and inter-line cutting applications have been made), (iii) cutting (in-line cutting and cutting plant (Vicia sativa L. (Fabaceae: Leguminosae) has been determined as parcel) and (iv) Control (application of traditional farming). In order to determine the effectiveness of the moisturizing plant, the hole hole sample method has been used for the purpose of evaluating epigean species at the top taxon level. During the study, epigean species of the class Amphibia, Arachnida, Insecta, Gastropoda, Malacostraca and Reptilia associated with the Atrhropoda, Chordata, Mollusca branches were sampled. When the data were evaluated along with all the year of study, the highest Shannon-Wiener diversity value was calculated in the fixed parcel as 1,9981. The dominant value increased or decreased in reverse proportion to diversity is calculated at the highest parcels of control (0,2746), foreign grass breeding (0,2290), chemical (0,2172) and figo (0,1686) respectively. It is determined that the habitat with the lowest dominance is the fifth parcel. According to the percentage of similarity, the most similar parcels were foreign grass and control parcels, and this similarity rate was calculated at 83,879%. It was found similar to the group that was formed by fiber, control and foreign grass cutting parcels at 71,688%. Also, the chemical parcel was calculated as similar to the group in which the rest of the work areas were formed by 52.04%. Although fiber and chemical applied parcels are within the same garden limits, only 58%. 012 is similar. According to the results of this study, the biological diversity in the agro-ecosystems where covers are applied has a higher biological diversity value than the agro-ecosystems where conventional agriculture is applied. Also, when compared these two different methods of application in terms of similarity, it can be said that the similarity rates could increase due to the differences in the epigean species living in those agro-ecosystems.
