Composition and Diversity of Soil Arthropods of Rajegwesi Meru Betiri National Park

Abstract

Meru Betiri National Park (MBNP) is one of the nature conservation area that has the potential of flora, fauna, and ecosystems that could develop as a nature-based tourism attraction. The existence of certain indicator species was related to estimation of stress level and disturbance on ecosystem stability for making strategic decisions about the restoration in this area. One of the important indicator species at forest ecosystem were soil arthropods. Aim this research were analyzed composition and diversity of soil arthropods at Rajegwesi, MBNP areas. The methods in this research used pitfall trap, measurement of distribution structure and soil arthropods composition based on the Shannon -Wiener index, Morisita similarity index and Importance Value Index (IVI). The number of families and individuals of soil arthropods found in the coastal area of Rajegwesi consists of 10 order with 21 families (702 individual). The number of individuals of the order Hymenoptera, Coleoptera, Collembola and Araneida was more widely found. Soil arthropods diversity index on each land use indicated that soil arthropod diversity in these areas were moderate. Soil arthropod community of orchards and forest had a similarity of species composition, whereas soil arthropod community of savanna had a similarity of species composition with paddy fields.

The Refugia Attract Arthropods in a Paddy Field in Malang, East Java, Indonesia

“…This study showed the huge number of ants (Formicidae) observed both in treatment and control. Formicidae are predominantly dominant in a variety of habitats e. g in olive cultivation fields, konjack, grassland, farmland (Leksono et al, 2011;Onyeka and Ugwumba, 2013;Zayadi et al, 2013;Azmi et al, 2014). Formicidae occupies several functional roles in the ecosystem including as nectar feeder, predator, scavenger and seed feeder (Widyastuti, 2002).…”

“…Botol jebak diisi dengan formalin 4% dan cairan deterjen antara 2-5 cm tinggi botol. Lubang jebakan dipasang dipermukaan tanah dan diusahakan permukaannya rata dengan permukaan tanah di sekitarnya (Herlinda et al, 2008;Zayadi et al, 2013;Halli et al, 2014). Setiap titik botol sampel tandai dengan GPS untuk didapatkan koordinatnya (gambar 1).…”

“…Adanya familia Formicidae yang sangat dominan menunjukkan bahwa peran Formicidae di lingkungan sekitar adalah sebagai bahan pengurai, simbiosis mutualisme dengan aphid, dan sebagai predator (Riyanto, 2007), adanya semut (Formicidae) karena pada area tersebut merupakan area yang biasanya ada tumbuhan yang sengaja ditanam (Johnson, 2000). Disamping itu juga perbedaan kemelimpahan individu dan spesies dari arthropoda disebabkan oleh diversitas vegetasi, kondisi lingkungan dan kelimpahan serasah di area tersebut (Zayadi et al, 2013).…”

Dinamika populasi Collembola pada tanaman kelapa sawit di perkebunan Cikasungka Kabupaten Bogor

“…Adanya hubungan jenis Collembola tertentu dengan curah hujan dan nilai pH tanah menunjukkan bahwa kehidupan beberapa jenis tersebut dipengaruhi oleh perubahan lingkungan. Menurut Zayadi et al (2013), perbedaan struktur komunitas arthropod tanah, seperti Collembola dipengaruhi oleh faktor lingkungan, seperti kelembaban, temperatur, pH tanah, C/N, dan bahan organik tanah.…”
