This study aims to determine the distribution and abundance of reef fish in coral reef waters of Sub District Maba and was conducted at 10 stations. Data were collected by conducting visual census on the 50-meter transect line at 5 meters depth. In addition to revealing the number of species and abundance of coral fishes, data were analyzed to determine the diversity index (Shannon-Wiener). Based on field observations, most of the reef fishes  found in the Sub-district of Maba surrounding waters are being categorized to have less potential category (50%);  fair potential (41.67%); potential (8:33%); and  there is no population being classified in very potential category. Several locations have the potential reef fish condition were Jara-jara Cape, Gee Island, and Para-para Island.  Based on the existence of the target species population, in term of species richness and abundance, it is assumed that largely dominated by the target fish species that has low economic value. On the other hand target fish that has high economic value only consists of few species such as grouper, jacks, sweetlips, and snappers.   Keywords : coral fishes,  coral reef, sub district maba ABSTRAK Penelitian ini bertujuan untuk mengetahui distribusi dan kelimpahan ikan karang di perairan terumbu karang Kecamatan Maba.

The development of herbaceous species according to the time of monitoring at certain sample locations in the PT Adaro Indonesia reclamation area has never been published. The purpose of the study was to compare the diversity of species and the similarity of plant communities growing in certain locations in two consecutive monitoring periods. Four locations that have been revegetated were sampled. At each location, 13 measuring plots (20 m x 20 m) were made and placed systematically. In each of these plots, 2 sub-plots (5 m x 5 m) were placed in 2 angles in opposite positions. From each sub-plot data in the form of herbaceous species names and number of individuals were collected. In one location, the number of plots changed because part of this location turned out to be active mining areas. The number of remaining plots (6 plots) was considered to not affect the results. Data is processed to obtain the density of each species at a certain location (Ki), the relative density of certain species (KRi), the frequency of each species at a certain location (Fi), the relative frequency of certain species (FRi), the importance value index (IVI), the index of species diversity Shannon-Wienner (H'), and the similarity index of the Dice community (IS). The number of species varies at each sample location and shows an increase from first monitoring to second monitoring. The species diversity index also increases. Community similarity index varies, both with calculations based on the presence or absence of species and based on the IVI. Both methods of calculation can be used but it is recommended to use calculations based on IVI.Keywords: Diversity, Monitoring period, Reclamation area, Similarity

<p>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.</p><p> </p>
