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

Abstract

Soil ecosystems are ecosystems related to the degradation of organic matter. University of Bengkulu is an area that has two kinds of soil ecosystems; secondary forest ecosystems and park ecosystems. Arthropods are one of the faunas living in the University of Bengkulu campus ecosystem. Camponotus dominates the secondary forest area, while Solenopsis dominates the park ecosystem. Data were obtained from two ecosystems (secondary forest ecosystem and park ecosystem). The results show that there are five classes with 199 individuals, while in the park ecosystem, there are four classes with 250 individuals.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 even distribution of soil arthropods in both ecosystems is high. Moreover, there is no dominance by one type of soil arthropods in both ecosystems. The diversity of arthropods in the secondary forest ecosystem is higher than that of the park ecosystem. The number of individuals in the park ecosystem is higher than in the secondary forest ecosystem. In both ecosystems, the most commonly found are from the Formicidae family

Diversity and Abundance of Soil Arthropods in Terrestrial Area of Situ Lengkong Panjalu, West Java, Indonesia

“…In the study area, many of the bases of woody plants were found to have been cut down, making Formicidae abundant. According to Fauzi et al (2023), Formicidae make nests in areas where there are woody plants or former woody plants. Ant nests are found in soil areas, whether covered or not, between rocks, wood, plant roots, and twigs on bushes or trees.…”

“…The more abundance, distribution, and diversity of ground-surface insect species, the more species, and individuals area reflect, and the more stable the ecosystem (Magurran, 2004). Insects in an ecosystem are a group of biota that have an essential role in maintaining the balance or stability of the ecosystem because they have an even distribution in trophic levels (Fauzi et al, 2023). According to Yanuwiadi et al (2023), the diversity of soil arthropods shows a variety of ecological roles in positioning themselves in food webs in terrestrial ecosystems.…”
