Vegetation analysis of the Forest Park of Pocut Meurah Intan (THRPMI), Seulawah Subdistrict, Aceh Besar, Aceh Province

Abstract A study entitled “Vegetation Analysis of the Forest Park of Pocut Meurah Intan, Seulawah Subdistrict of Aceh Besar, Aceh Province” has been conducted since April 2019 until November 2019. A transect method and squares were used in this study. The transect method was used to record species composition throughout the observation stations (inventory of species), including stands of pine (Pinus merkusii) with ten stations transect, stands of eucalyptus (Eucalyptus urophylla), stands of cacao (Theobroma cacao), and natural forests within a radius of 2 km around the THRPMI office. The squares method was used to record the species in the same locations to replicate each station by ten squares of samples for vegetation analysis. The parameters measured in the field were frequency, density, and dominance of each species. Analysis of vegetation covered Importance Values (IV), Diversity Index (H ’), and the Similarity Index (SI). Results showed that there were 49 familia found with the composition of species in the entire observation stations comprising of 111 species with 58 species of trees, 12 species of shrubs, and 41 species of herbs. Additionally, the results showed that the species of vegetation with the highest IV were coarse grass (Imperata cylindrica), lawn pait (Axonopus compresus), and selasi (Vernonia cinerea) with IV of 72.01, 65.34, and 57.24, respectively. Results of analysis Species Diversity Index (H ’) showed that the Pinus merkusii had H’ of 2,134, whereas Eucalyptus urophylla had H ’of 1.965, and Theobroma cacao had H’ of 1,067. The results of the analysis of Community Similarity Index showed that all stations had the same relative SI of 75%.

Amphibians are part of biodiversity that spread in various places in the world. Amphibians have an important role in maintaining the balance of the ecosystem as part of the food chain system. However, lack of public understanding caused the potential of Anura amphibians to have not been explored optimally hence research on Anura amphibians in the Wan Abdul Rachman Great Forest Park (Tahura WAR) is very important to support Anura's conservation efforts. This study aims to understand and identify the diversity of Anura order amphibians in the Protection and Utilization Blocks of the Tahura WAR on forest and river habitat types. Data was collected by using Line Transect and Visual Encounter Survey method. Data collection using Line Transect was conducted by making a narrow transverse path at the observation site, while the Visual Encounter Survey was conducted by making a wildlife observation path with 3 replications. Analysis of the data used included amphibian diversity, community similarity index, and species evenness. The results found 25 individuals of Anura amphibians in the Protection Block and 40 individuals in the Utilization Block of Tahura WAR. Overall, 65 individuals were found consisting of 3 species of amphibians from 2 families i. e., 2 species of the Ranidae family and 1 species of the Bufonidae family. The results showed that the species diversity index, species richness index, and community similarity index in the Protection and Utilization Blocks of Tahura WAR were categorized as low. Reforestation needs to be done so that the Anura habitat is maintained.Keywords: amphibian, biodiversity, order Anura, Tahura WAR

Anthropogenic impact on the population of ground beetles leads to a change in their numbers, structure of dominance, density, species composition, spectrum of life forms. This makes the beetles Carabidae a convenient and informative bioindicator of the ecological state of biocenoses. The material for this work was the Carabidae collections conducted in June-August 2016-2017 in the park zone of different regions of Barnaul, differing in location, area, hydrological regime, vegetation cover, purpose and anthropogenic load. When processing the material, the quantitative, species and generic composition of the carabidae was determined, calculations were made for such indicators as the Berger-Parker dominance index, the Shannon species diversity index (Hs), and the Jacquard species similarity index. The fauna (Coleoptera, Carabidae) of the park zone of Barnaul is represented by 55 species belonging to 20 genera. The dominant group is represented by species belonging to steppe, forest and polyzonal groups. Forest-steppe species of ground beetles as dominants have not been identified in any of the investigated territories. The greatest variety of ecological groups was noted on the territory of the Yubileyny рark, which is explained by the presence of zones with various microclimatic conditions, the presence of a birch grove that flows through the park with the Pivovarka River, and a wide log in the park. Registered species belong to eight groups of life forms belonging to two classes - zoophagous and myxophytophagous. On the numerical and species abundance, zoophages predominate. The spectrum of life forms corresponds to the zonal spectrum characteristic of the forest-steppe zone.

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.

Abstract. Riefani MK, Soendjoto MA. 2021. Birds in the west coast of South Kalimantan, Indonesia. Biodiversitas 22: 278-287. There is no comprehensive data on birds in the west coast of South Kalimantan, yet the areas are pressured by human activities, especially the rapidly growing tourism. This study aimed to investigate the diversity of bird species that occurred in the west coast of South Kalimantan and to compare the similarities of bird communities across four villages used as the sampling sites, i.e. Sungai Rasau, Sungai Bakau, Tabanio, and Pagatan Besar. Transect method combined with concentration count method were used to record diurnal bird species and number of individuals in five replications from April to September 2020. The observation area was 100 m from the shoreline toward the sea and 400 m from the shoreline toward the inland along 2 km with observation time was 07.00-11.00 and 16.00-19.00. Shannon Wienner species diversity index (H'), a Dice community similarity index based on the presence or absence of species (ISD), and a community similarity index (modification) based on the number of individuals per species (ISM) were analyzed. In total, there are 101 bird species recorded belonging to 41 families with Sungai Bakau Village has the highest number of species (81 species), while Pagatan Besar Village is the lowest (62 species). Thirty-four species are categorized as waterbirds. Twenty-three species are categorized as migratory birds. In terms of diversity index from highest to lowest are Sungai Bakau (4.04), Sungai Rasau (3.95), Pagatan Besar (3.65), and Tabanio (3.48). The similarity of the ISD community ranges from 0.74-0.84, while the ISM ranges from 0.73-0.90. One case (Sungai Bakau - Tabanio) shows that community similarity based on the number of individuals per species is smaller than based on the presence or absence of species. Based on the protection status following Indonesian government regulation, most (84.16%) birds are categorized as unprotected, while based on the conservation status of IUCN, the majority (91.09%) are Least Concern. The results of this study can be used as baseline information for sustainable management of the area in various aspects, including future research (such as on pest and disease control), tourism (such as bird watching), and education (such as field guide).

Abstract. Siregar M, Helmanto H, Rakhmawati SU. 2019. Vegetation analysis of tree communities at some forest patches in North Sulawesi, Indonesia. Biodiversitas 20: 643-655. Deforestation has caused a decline in forest area in Indonesia. Now natural forests is left in the conservation areas while those outside conservation areas are narrow and fragmented. This study aims to analyze forest vegetation and conservation status of the species of trees in some forest patches in North Sulawesi. Diversity, structure and type of tree communities at five forest patches, namely in the villages of Bukaka, Garini and Lambak in East Bolaang Mongondow District, and Soyowan and Basaan villages in Southeast Minahasa District, North Sulawesi Province were studied using a point center quarter method. The total number of tree species (dbh ≥ 10 cm) across five patches is 84 species. The highest number of species is in Garini (37 species), followed by Lambak (25 species), Soyowan (19 species), Bukaka (10 species) and Basaan (7 species). The species diversity index also shows the same pattern with such species richness, but the dominance index demonstrates opposite trend. The highest evenness index (E) is found in Bukaka (E = 0.9524), followed by Soyowan (E = 0.9061), Garini (E = 0.7873), Basaan (E = 0.7809) and Lambak (E = 0.7099). The most important tree species based on the Species Important Value (SIV) in Bukaka is Ficus sp. (SIV = 52.17), in Garini is Octomeles sumatrana (SIV = 25.73), in Lambak is Boehmeria cylindrica (SIV = 65.03), both in Basaan and Soyowan is Dracontomelon dao with SIV of 96.87 and 46.46 respectively. The beta diversity analyzed based on species similarity index of Jaccard and Whittaker 's index shows a relatively large change in species composition from one location to another. The family of Moraceae, Malvaceae, Anacardiaceae, Annonaceae and Lauraceae are listed as the widest family with a relatively high population. The highest tree density is found in Bukaka (721 trees ha-1), followed by Lambak (482 trees ha-1), Basaan (439 trees ha-1), Garini (292 trees ha-1) and Soyowan (164 trees ha-1). The highest basal area is also found in Garini (53.59 m2 ha-1), followed by Basaan (51.62 m2 ha-1), Lambak (30.74 m2 ha-1), Soyowan (25.13 m2 ha-1) and Bukaka (20.98 m2 ha-1). The results of Cluster analysis using data of species abundance indicate that the five research locations tend to form two types of tree communities. The first community consists of Garini, Soyowan, Lambak and Bukaka, while the second community is represented only by Basaan.
