Abstract. Darmawati, Mulyadi A, Suwondo, Harto S. 2021. The diversity and vegetation structure based on growth levels at an urban green campus in Pekanbaru City, Indonesia. Biodiversitas 22: 5123-5132. The Bina Widya campus of the University of Riau (UNRI), Pekanbaru, Indonesia has the green open space (GOS) in its area and there are many species of vegetation. In a green open space, variables like diversity and vegetation structure must be considered based on growth levels, this study intended to determine the composition, structure, and diversity of vegetation.The results showed that there were 33 species of trees, 29 species of poles, 16 species of saplings, and 8 species of seedlings from 44 species belonging to 22 families. There were 874 individuals which consisted of 534 trees, 207 poles, 87 saplings, and 46 seedlings. The most common species found was Swietenia macrophylla King (Meliaceae) with 289 individuals. The highest Important Value Index of vegetation species at each growth level was the tree of Alstonia scholaris (L) R.Br (300%, location IX), the pole of Hibiscus tiliaceus L. (300%, location VII), saplings of Vitex pinnata L. (300%, location IV), and S. macrophylla King (300%, locations I), seedlings of S. macrophylla King (300%, location I), and Garcinia mangostana L (300%, location IX). We did not find vegetation species at the levels of sapling or seedling in locations of II, III, V, VI, and VIII. It is necessary to replant the vegetation. The highest Species Diversity Index (H') at location X was trees (2.34), poles (2.28), saplings (1.77), and seedlings (1.17). The average H’ vegetation at Bina Widya Campus UNRI was 2.44 (medium). Vegetation on the Bina Widya Campus is fairly steady in terms of delivering advantages for human environmental services.

It has been installed that the species richness of the blackflies of the north-eastern macroslope of the Ukrainian Carpathians counts 38 species of 2 genera: Prosimulium Roubaud, 1906 (2 species) and Simulium Latreille, 1802 (36 species). 20 species develop in the streams (Simpson's species diversity index (Іs) equals to 0,22), and 26 species develop in the rivers (Іs – 0,10). There are 8 common species of Simuliidae for both types of watercourses (similarity index by Czekanowski/Sørensen (І) is 0,26). 12 species of blackflies develop only in the streams, and 18 species develop only in the rivers. S. trifasciatum Curtis, 1839, S. reptanoides Carlsson, 1962, S. ornatum Meigen, 1818 and S. intermedium Roubaud, 1906 dominate in the hydrobiocenoses of the north-eastern macroslope of the Ukrainian Carpathians. S. trifasciatum and S. ornatum are widespread. It has been discovered that Simuliidae fauna of main altitudinal zonal plant groups of the region differs in composition and quantitative correlation of species. S. intermedium, S. ornatum, S. reptans Linnaeus, 1758 and S. trifasciatum are eurytopic. In the hydrobiocenoses of the district of beech forests has been registered 31 species (Is – 0.09), and in the watercourses of the district of spruce mountain Carpathian forests has been registered 24 species (Is – 0.18). It has been found out that with the decrease of height in the district of the beech forests, the value of Simpson's species diversity index decreases from 0.16 (20 species) in the subdistrict of the dark-coniferous-beech watershed forests to 0.11 (21 species) in the subdistrict of fir-beech and beech-fir precarpathian forests.

For gauging suitability of zygopteran odonates as bioindicators of ecosystems, an attempt was made to record the seasonal diversity of damselflies from seven different types of habitats in Paschim Medinipur District, West Bengal covering 14 land use sites. The study revealed existence of 19 species of damselflies belonging to 10 genera under two families. While the riparian zone had maximum number of species (15), paddy field had the lowest number (six). Ceriagrion coromandelianum and Agriocnemis pygmaea were the most common species. C. coromandelianum was eudominant in grassland and wetland-forest interface, whereas A. pygmaea was eudominant in fish pond and paddy field. Six species, viz., Paracercion calamorum, P. malayanum, Pseudagrion australasiae, P. decorum, P. spencei, and P. microcephalum were confined only to the riparian zone. Maximum abundance of damselflies was found in the riparian zone and minimum in the paddy field. Damselflies exhibited a distinct peak in March–April and a lesser peak in September–October. Most of the land use patterns exhibited similar zygopteran faunal composition. Species diversity index was moderate (1.4–2.5) and evenness index was on the higher side (0.76–0.94). Dominance Index ranged from 26.2 to 64.6. Riparian zone appeared to be the least stressed and most equitable habitat with highest diversity and evenness index and lowest dominance index. Paddy field seemed to be the harshest habitat for damselflies with least diversity and highest dominance index. The present study suggests that community analysis of damselflies can be quite useful in the assessment of the quality of any ecosystem.

Abstract The life of Balinese people can never be separated from ritual activities or religious ceremonies. The existence of telajakan is essential to preserve. Aside from being a traditional Balinese identity, it also provides space for ritual plants and biodiversity. So that effort is needed to manage the existence of telajakan. This research is expected to analyze the characteristics of telajakan and the existence of ritual plants found in telajakan. Field observation was undertaken to inventory distribution point of remains telajakan in Canggu village. The sampling method uses purposive sampling by tracing along the main road and marking the visible point of telajakan. Changes function of telajakan was found in the Canggu area, and in Penglipuran villages, there is still preserved. Following this study, 49 samples of remains telajakan were collected from Canggu village and 69 samples from Penglipuran village. The characteristics of telajakan can be observed with the structure and size. The result shows, the structure of telajakan can be any combination of an open ditch, covered ditch, pedestrians track, open ground, grass, and fence wall. Size of telajakan can be grouped into small size (width <50 cm), medium size (width 50-99 cm), large size (width 100-149 cm), and extra-large size (width > 150 cm). Based on survey research and observation, various plants are found in each sample. Seventy-seven species of plants were found in 49 samples of telajakan in Canggu village. Plumeria accuminata, Codiaeum Sp., and Bougainvillea spectabilis is the most common species. Meanwhile, in Penglipuran village, 117 species of plants were found in 69 samples of telajakan. Furthermore, the most common species found were Plumeria accuminata, Alternanthera ficoidea, Cordyline terminalis, and Cananga odorata. Result show both Canggu village and Penglipuran villages have high species diversity index (H′>3). Canggu village species diversity index amount 3.88 and Penglipuran village amount 4.12. The utilization of telajakan as space for ritual plants can preserve Balinese tradition and cultures’ local identity.

Observation Method

Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea. The species diversity index at the Arboretum has a value of 2.74, Campus S1 Forestry Untan with a value of 2.19 and Pendopo Park with a value of 2.02. This value indicates that species diversity in green open space is classified as medium.Keywords: butterfly diversity, green open space, bioindicator

Molluscs in Kabaena, Muna, and Buton Islands, Southeast Sulawesi. Kabaena, Muna, and Buton islands in Southeast Sulawesi waters have quite wide reef flats and rich in marine life, including molluscs. To determine the condition of mollusc communities in these waters, a study was conducted in May 2006 in five locations, namely Kabaena Island (2 stations), Muna Island (1 station), and the Buton Island (2 stations). The method used was transect squares starting from the beachfront perpendicular to the direction of the sea (the edge). From this study, 74 species of molluscs were obtained that consisted of 49 species of the class Gastropoda and 25 species of the class Bivalvia. Polinices tumidus, Engina alveolata, Vexillum sp., and Morula margariticola of the class Gastropoda and Gafrarium tumidum, Tellina sp.1, and Barbatia decussata of the class Bivalvia were molluscs that had a relatively large distribution. The highest mollusc density was found in Kalimbungu Bay (19.2 individuals/m2) and the lowest was in Lakeba (3.5 individuals/m2). Haelicus variegatus was a species that dominated the sand substrate in Kalimbungu Bay. The molluscs found in this study were common species in tropical waters. The value of species diversity index (H') ranged from 1.54 to 2.88. This value indicated the diversity of mollusc species was of moderate condition. Evenness index (J') ranged from 0.56 to 0.92 and dominance index (C) ranged from 0.08 to 0.40. Both values showed that the mollusc community in each study site was in a pretty good condition

Abstract The urban forest is part of the public green open space (RTH) formed from tree vegetation that affects temperature and humidity and reduces wind speed to provide comfort for residents in the vicinity. One of the urban forests in Medan is the Balai Wilayah Sungai (BWS) II Medan. Therefore, vegetation density has an influence on temperature and which affects the quality of urban forests. This study aimed to identify the structure and composition of the BWS II Medan urban forest vegetation. The vegetation analysis method used in this study is a combination method between the path method and the plotline method. The vegetation data that has been obtained is then processed to obtain the Important Value Index (IVI) and the Plant Species Diversity Index (H’). The results showed that the woody plants found in the urban forest of BWS II Medan were 20 species with the composition of seedlings of four species (26 individuals), saplings of twelve species (49 individuals), poles of eleven species (39 individuals) and trees of ten species (141 individuals). The species that dominates at the tree level is Trembesi (Samanea saman), with an IVI value of 118.16%. Meanwhile, the dominant plant species at the seedling, sapling, and pole levels were Mahoni (Swietenia mahagoni), with IVI values of 78.67%, 55.73%, and 103.62, respectively. Therefore, the level of diversity in the BWS II Medan Urban Forest for saplings is classified as moderate, while seedlings, poles, and trees are classified as low.
