Diversity and distribution of macroarthropods in the Nglanggeran Ancient Volcano, Gunungkidul, Special Region of Yogyakarta

Abstract

This research aims to describe the diversity and distribution of macroarthropods which consist of terrestrial, arboreal, and aerial arthropods at Nglanggeran Ancient Volcano, Patuk, Gunungkidul Regency, Special Region of Yogyakarta, Indonesia. This research descriptive survey research was conducted from March to May 2021. The data collection used purposive random sampling, determined intentionally by combination methods, consisting of hand sorting, pitfall trap, yellow pan trap, sticky trap, and hunting methods. The data collection took place in seven stations, namely Song Gudel, Rest Point 1 (1st Shelter), Bagong Mount (2nd Shelter), Camping Ground, 4th Shelter, 5th Shelter, and 6th Shelter. The results show that the ecosystem Nglanggeran AV has a high diversity category of macroarthropods, distributed at all stations but the highest diversity of macroarthropods is found at an altitude of 1300 to 1700 meters above mean sea level (AMSL) with different vegetation characteristics. There are 56 families, in 15 orders, and in five classes macroarthropods, namely Arachnid, Insect, Malacostraca, Diplopods, and Chilopods. The result of the Shannon-Weiner diversity index is 2.451, the Evenness index is 0.20 72, and the Margaleff index is 7.572. The variations in the diversity at every shelter are discussed in this paper.
