Abstract. Koneri R, Nangoy MJ, Siahaan P. 2019. The abundance and diversity of butterflies (Lepidoptera: Rhopalocera) in Talaud Islands, North Sulawesi, Indonesia. Biodiversitas 20: 3275-3283. Butterflies play a number of roles in the ecosystem. They help pollination and natural propagation and also are an important element of the food chain as prey for bats, birds, and other insectivorous animals. This study aimed to analyze the abundance and diversity of butterflies (Lepidoptera: Rhopalocera) in the Talaud Islands of North Sulawesi, Indonesia. The sampling method used was scan sampling along the transect line in three habitat types, namely, forest edge, farmland, and shrubland. The species diversity was determined by using the diversity index (Shanon-Wiener), the species richness index was calculated using the Margalef species richness index (R1), while species evenness was counted by using the Shannon evenness index (E). One-way ANOVA and Duncan test at the 95% significance level were used to determine differences in species richness, species abundance, species diversity values, and species evenness among habitat. In this study, we identified 1008 individuals of butterfly consisted of 32 species and five families. Nymphalidae was the dominant family with 15 species, while the highest abundance species was Eurema tominia. The highest species abundance, species richness index, species diversity index, and species evenness index were found in forest edge habitat. The largest similarity index of the composition of the butterfly communities was found in forest edge and farmland habitats. The abundance and diversity of butterfly species in a habitat are strongly influenced by the diversity of vegetation as shelter and source of nectar for butterflies, and the existence of a river as a source of water and minerals from wet rocks, mud, and sand along the riverside.

Abstract. Koneri R, Nangoy MJ, Wakhid. 2021. Richness and diversity of insect pollinators in various habitats around Bogani Nani Wartabone National Park, North Sulawesi, Indonesia. Biodiversitas 22: 288-297.  The pollination of plants by insects is one of the most important and essential ecosystem services in natural and agricultural landscapes and Insect pollinators play an important role in this process. This is because they help to transfer pollen from the anther to the stigma, which leads to fertilization. This study aims to analyze the richness and diversity of insect pollinators in various habitats around the Bogani Nani Wartabone National Park, Toraut, North Sulawesi. It was carried out from June to August 2020 on three types of habitats around the National Park, namely forest edges, shrubs and agricultural land. For each habitat, four plots with a size of 50 m x 25 m were made with a distance of 100 m between them. The insect pollinator observation technique used was the scan sampling method. Furthermore, data analysis was carried out on abundance, richness index, diversity index, species evenness index, dominance index and the relationship between sampling locations and environmental factors. The results showed that there were 979 insect pollinators caught at the observation point, which consisted of 60 species from 16 families and 4 orders and the most common order was Hymenoptera with 31 species. The species which were found based on their relative abundance indicated that Nomia strigata was the most abundant followed by Nomia melanderi, Apis dorsata, Ropalidia fasciata and Amegilla zonata. Furthermore, the highest abundance of insect pollinators was found in shrub habitats, while the highest species richness and diversity were found at the forest edge. Therefore, it was concluded that different types of habitat affect the richness and diversity of insect pollinator species around the Bogani Nani Wartabone National Park. In addition, this proves that the forest area of Bogani Nani Wartabone National Park generally supports the abundance, richness, and diversity of insect pollinators, which were discovered in the surrounding habitats, namely shrubs and agricultural land.

Abstract. Koneri R, Nangoy MJ, Maabuat PV, Wakhid. 2023. Butterfly species in Bogani Nani Wartabone National Park, North Sulawesi, Indonesia. Biodiversitas 24: 1242-1251. Changes in the landscape spatially and temporally impacted the fauna distribution and diversity, such as butterflies. This research analyzed the diversity in the Bogani Nani Wartabone National Park area, in Toraut Village, West Dumoga Sub-district, Bolaang Mongondow District, North Sulawesi, Indonesia. A survey method was used with purposive sampling in 4 habitats: a waterfall located within the national park area, forest edge, agricultural land, and shrubs. The sampling and sweeping techniques following the line transect were applied randomly along 300 m in each habitat type. Furthermore, data analysis included distribution, abundance, richness index, diversity index, species evenness index, the correlation between environmental factors and species diversity, and butterfly species similarity index between habitats. Overall, 1594 individuals from 71 species in 5 families were identified. The family with the highest number of species and individuals was Nymphalidae, while the most common was Catopsilia scylla of the orange emigrant. The highest average abundance and evenness were found at the forest edge, while the highest richness and diversity were in the waterfall. According to the analysis of similarity (ANOSIM), the composition of butterflies in four habitats was significantly different. Principal component analysis (PCA) showed that the waterfall habitat was characterized by high relative humidity, low air temperature, and light intensity. The ordinance plot represented a waterfall separated from the three other habitats; hence, the environmental factors differed. Waterfall and forest edges had the highest diversity due to the complex vegetation structure and environmental factors supporting survival.
