A Study on the Relative Abundance and Biodiversity Indicators of Springtails (Hexapoda: Collembola) in two ecosystems in Mazandaran province (Iran)

View on Scopus In this study the biodiversity and relative abundance of Collembola was evaluated in two different ecosystems, citrus field and forest in Mazandaran province, Iran. Samples were carried out during ۲۰۱۶ and ۲۰۱۷. In each site, soil was sampled by a collecting core from ۵×۵ cm in surface area and a depth of ۱۰ cm. Species richness, biodiversity and the indices of similarity were calculated. The results of T-Test showed that in two years (۲۰۱۶ and ۲۰۱۷), the values of Shannon-Wiener diversity and Simpson species diversity index were significantly different between sampling areas (Pvalue<۰.۰۵), but the values of Margalef richness and Pielou evenness index were not significantly (Pvalue˃۰.۰۵). In the year ۲۰۱۶, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were ۱.۹۲ ± ۰.۱, ۰.۸۳ ± ۰.۰۳, ۲.۰۱ ± ۰.۲ and ۰.۹۴ ± ۰.۰۴ respectively, and in citrus field were ۱.۴۴ ± ۰.۱۱, ۰.۷۳ ± ۰.۰۲, ۱.۴۶ ± ۰.۳۷ and ۰.۹ ± ۰.۰۳ respectively. Also, in the year ۲۰۱۷, Shannon-Wiener index, Simpson index, Pielou evenness and Margalef species richness in Dasht-e Naz forest were ۱.۷۹ ± ۰.۰۵, ۰.۸۱ ± ۰.۰۸, ۱.۳۸ ± ۰.۲۵ and ۰.۹۴ ± ۰.۰۹ respectively, and in citrus field were ۰.۹۸ ± ۰.۲۲, ۰.۵۸ ± ۰.۰۸, ۱.۰۲ ± ۰.۳۵ and ۰.۹۵ ± ۰.۰۵ respectively. In general, the results showed that the abundance and biodiversity of Collembola in Dasht-e Naz forest was higher than in citrus field.
