Abundance and diversity of soil arthropods in the secondary forest and park at the University of Bengkulu

Abstract

Soil ecosystems is related to organic matter degradation. The University of Bengkulu has two kinds of soil ecosystems, namely, secondary forest ecosystems and park ecosystems. Arthropods are one of the faunas in the University of Bengkulu campus ecosystem. This study aims to investigate the diversity of soil arthropods inhabiting the university of Bengkulu. The results showed five classes with 199 individuals in secondary forest. While in the park ecosystem, there are four classes with 250 individuals. Camponotus dominates the secondary forest area, while Solenopsis dominates the park ecosystem. The secondary forest ecosystem diversity index value is 2.73, and the ecosystem diversity index value is 1.91. The evenness index value of the secondary forest ecosystem is 0.78, and the park ecosystem is 0.76. The secondary forest ecosystem dominance index value is 0.09, and the park ecosystem dominance index is 0.17. The diversity of soil arthropods in secondary forest and park ecosystems is in the category of moderate diversity. The evenness distribution of soil arthropods in both ecosystems is high. Moreover, there is no dominance by one type of soil arthropods in both ecosystems. In both ecosystems, the most commonly found are from the Formicidae family.
