Vegetation diversity and its interspecies association with merbau (Intsia bijuga) at three habitats of tropical rain forest in West Papua, Indonesia

Abstract. Tasik S, Widyastuti SM, Musyafa, Suryanto P. 2021. Vegetation diversity and its interspecies association with merbau (Intsia bijuga) at three habitats of tropical rain forest in West Papua, Indonesia. Biodiversitas 22: 3383-3391. The stability of vegetation community indicated by species diversity, structure and composition affects the relationship between species. The understanding of interspecies association in their natural habitat is important especially for management and conservation strategies of species with particular interest, including merbau (Intsia bijuga O. Colebr Kuntze), a timber tree species with high commercial value. This study aims to investigate the diversity and composition of vegetation coexisting with merbau, and to see whether there is pattern of interspecies association with merbau. Vegetation analyses of species richness, diversity index, evenness index and interspecies relationship were conducted at three research locations in West Papua, Indonesia, namely Mount Meja Natural Tourism Park (Hutan Taman Wisata Alam Gunung Meja/HTWAGM), Bembab Beach Forest of South Manokwari (Hutan Bembab Pantai Manokwari Selatan/HBPMS) and Bembab Mountain Forest of South Manokwari (Hutan Bembab Gunung Manokwari Selatan/HBGMS). The results showed that the species Caryota rumphiana, Licuala sp 1, Calophyllum inophyllum, Garcinia pichoriza, Pometia coreacea and Pometia pinnata always grew side by side with Intsia bijuga in three locations. Furthermore, the association analysis indicated a positive and strong relationship between Intsia bijuga and Pometia coreacea, Licuala sp1, Licuala sp 2, Caryota rumphiana at all three research sites. In addition, Pometia coracea had the highest Chi-square value (X2 = 20.00) with the value of the three association indexes reached maximum value. We also found that the vegetation communities in the habitat of merbau had varying vegetation structure and composition as well as biodiversity indicators, yet they were all at stable state. The finding on vegetation analyses was confirmed with the result of soil analyses in which the physical and chemical properties had optimal conditions for vegetation to grow, including for merbau.

Mount Sigogor Nature Reserve area is a mountainous tropical rain forest, administratively located in Pupus Village, Ngebel District, Ponorogo Regency, East Java, Indonesia. One of the main functions of this nature reserve is as a water catchment area for the villages around the nature reserve area. Water sources and flows within the Mount Sigogor Nature Reserve area have the potential as natural habitat for dragonflies. This study aims to determine the diversity and abundance of dragonflies (Odonata) in the Mount Sigogor Nature Reserve Area. The method of collecting dragonflies data used the Visual Day Flying method by recording the diversity of dragonflies species and counting the number of individuals from each observed dragonflies species. The data obtained were analyzed using the Relative abundance, Shannon-Wiener Heterogeneity Index and the frequency of Presence. The results of the research conducted showed that there were 14 species from 7 families with a total of 464 individuals. The Shannor-Wiener diversity index shows that the diversity value is H'= 1.81. Meanwhile, the presence frequency analysis showed that there were four species with a value of 100% which were classified as abundant Frequency of Presence, namely Euphaea variegata, Vestalis luctuosa, Rhinocypha anisoptera and Coeliccia membranipes.

Liana is group of climbing species which is typical and characterize the tropical rain forest. This species have important value both ecologically and economically. However, data on this group on species in South Sulawesi, in particular in the Hasanuddin University Experimental Forest is not yet available.This study aimed to determine the diversity and abudance liana species present in the natural forest area of Hasanuddin University Experimental Forest. 15 plots was set in the order to observe the diversity and abudance of liana species. The data were analysed and presented interm of important value index, diversity index, abudance index, and evenness index.

Land type changes in the super wet tropical rain forest area caused fluctuations in the diversity of soil fauna which caused disruption of ecosystem balance. This research was conducted for four months, in November 2017-February 2018. Data on soil fauna was taken using pitfall traps and hand sorting. Furthermore, the soil fauna data obtained were identified and calculated the value of the diversity index, evenness and dominance on each type of land for four months. The results showed that forests had a high diversity index of soil fauna, which were 3,134, 3,313 and 3,314 in the first to the third month. While in the 4th month the forest diversity index decreased to 2,981. In open land, the soil fauna diversity index value is moderate, which is 2.631, 2.998, 2.782 and the diversity index increases in the fourth month, is 3.084. Mixed gardens have a value of the fauna diversity index of 2,728, 3,113, 2,870 and increased in the fourth month of 3,084. Whereas monoculture gardens have diversity index values of 2,527, 3,214, 2,935 and 2,927. Changes in land types of super wet tropical rainforests have an effect on changes in the level of diversity of soil fauna and not always these changes reduce the level of diversity of soil fauna.

Indonesia is the second largest mega biodiversity of the world. One of the forest resources are soil insects. Soil insects improved the soil physical properties, added organic material content, and used as bio-indicator of environmental conditions of conservation areas, forests, or mountains. The aim of this research was to get information about the diversity, dominance, and similarity index of soil macro insect in Alas Purwo National Park, Banyuwangi, East Java, Indonesia in 2017. Locations were selected based on purposive random sampling considering 2 habitat types; coastal forest path and tropical rain forest path. The method of this research was used pitfall trap. Insects were identified at Laboratory of Ecology, Biology Department, Faculty of Science and Technology, Airlangga University, Surabaya. The results showed that the diversity index of soil insects in the coastal forest path was 1.611 and in path of tropical rain forest was 0.855. It means that the diversity of soil macro insect in coastal forest path were medium and in path of tropical rain forest was low. The Dominancy index of coastal forest path was 0.334 and in path of tropical rain forest was 0.433. It means that the community was stable, there was no species domination. The similarity index of soil insects in both paths have a 58.8%, was a unity of the same community.

The methodological approach and methodical problems of evaluation and mapping of biodiversity of mountain forest territory in Primorsky Krai (south of the Russian Far East) are considered. The complex evaluation of biodiversity is presented according to the scheme: (ecotopical environments → vegetation → animal population) ← fire-danger. It is proposed to compile the maps of ecotopical diversity on a basis of diversity index and contrast of relief characteristics, and the maps of geobotanical and zoological diversity — on a basis of spatial extrapolation of indexes relating biota to environmental conditions. The examples of construction of appropriate maps are given for Primorye Region.
