Background. In the 21st century, landscape transformation processes are underway in large cities, which affects the stability of wildlife habitats. Habitat transformations often reduce species richness due to a decrease in the population sizes of some species, and therefore, small in number and rare species are eliminated from bird communities. Rare species can have unique consortive relationships, which makes them particularly important for the long-term ecosystem functioning. A study of the avifauna of forest parks makes it possible to develop an algorithm for the coexistence of human and birds. Methods. The number and distribution of birds were determined by route counting. The total length of the fixed route was 5.7 km in Kyiv and 3.5 km in Kharkiv. On each route, observations were carried out annually with three repetitions during the nesting period when the birds are most attached to their habitats (end of April–May–June). The average data for the total study period (2013–2017) were calculated for each city. For the average number, the standard deviation was calculated. An analysis of the faunogenetic structure of avifauna was carried out according to the method developed by V.P. Belik. A faunogenetic complex is a group of animal species associated by a common origin with ecosystems of a certain landscape-geographical zone. We also classified bird species into ecological groups according to the patterns of microhabitat choice. To compare the α-diversity of bird in the forest-park zones of cities, a number of commonly accepted indices that express the correlation between the number and density of species were calculated: 1) Berger–Parker dominance index: DBP = Nimax / N; 2) Shannon diversity index: H´ = -∑(Pi × LnPi); 3) Pielou evenness index: E = H´ / LnS; where: Nі– the number of each species; Nimax – the maximum value of Nі; N = ∑Ni – the total number of all species (pairs/km); Pi = Ni / N – the ratio of each species; S – total number of the species. Results. The study presents a comparative analysis of diversity and faunogenetic structure of avifauna in the forest park zones of Kyiv and Kharkiv, inhabited by 71 breeding species of birds that belong to 10 orders. In the eastern region, the proportion of birds of the boreal and the European forest-steppe complex decreases, but the share of the desert-mountain complex increases. The fauna of the European nemoral complex dominates (32.8 % in Kyiv and 40.4 % in Kharkiv). The basis of the communities are dendrophils: 83.6 % (n = 67) in Kyiv and 82.7 % (n = 52) in Kharkiv. The dominant species in all forest parks are the great tit (Parus major) and chaffinch (Fringilla coelebs). Conclusions. The differences in the faunogenetic structure of bird communities are due to the proximity of model forest parks on the territory of Kyiv to the forest natural geographical zone, and on the territory of Kharkiv to the steppe, which leads in the eastern region to a decrease in the proportion of birds of the boreal and the European forest-steppe complex while the proportion of desert-mountain complex increases. Dendrophils predominate significantly, and the share of sclerophils and limnophils in total is less than 20 % of the bird community in the forest parks of each city. As a consequence of the fragmentation of the Kiev forest park zone, the diversity of nesting birds communities in the forest-park zone of Kyiv is slightly lower than of Kharkiv, and the pressure of the dominant species is more significant.

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%. It can be concluded that the species composition of the study area dominated by tree species, species diversity index (H ’) in all observation stations varied ranging from 1.067 to 2.134, and the relative Community Similarity Index was 75%.

Abstract. Rambey R, Susilowati A, Anna N. 2019. Genetic diversity of mindi (Melia azedarach) from community forest in Deli Serdang, North Sumatra, Indonesia revealed by microsatellite marker. Biodiversitas 20: 1708-1712. Melia azedarach or locally known as mindi is fast growing and one of important tree species for community forests especially in West Java and North Sumatra, Indonesia. High demand for its wood must be accompanied by increased productivity through planting of high-quality seed. There is still lack of information about genetic diversity of mindi from different seed source in North Sumatra. Therefore, our research was conducted to determine genetic diversity of mindi from different seed source in North Sumatra through microsatellites marker. Leaf samples originated from three populations Percut Sei Tuan, Pancur Batu and Biru-Biru were used in this study. The SSR markers were from Azadirachta indica i.e. Ai5, Ai 11, Ai 13, Ai 14 and Ai 34. Molecular data were analyzed using Popgene and NTsys version 2.0. The result showed that number of alleles (na) ranging from 1.80 to 2.80, and percentage of polymorphic loci (PPL) ranging from 60 to 80 %. The level of genetic diversity showed that mindi in North Sumatra has moderate value (He: 0.244 to 0.269). It indicated that assessment of genetic diversity of M. azedarach North Sumatra is necessary for improvement and conservation of a species.

A total of 320 species from 42 families were registered in the herpetobios (stratobiont and epigeobiont beetles) of the urbocenosis of Kharkiv. Among these more than 160 species are recorded for the first time for this metropolis. Four species of ground beetles (Notiophilus germinyi Fauvel, Clivina fossor L., Laemostenus terricola Herbst and Masoreus wetterhali Gyll.) were not listed for Ukraine in the Catalogue of Palearctic Coleoptera. The species Omosita japonica Reitter, 1874 (Nitidulidae) is new for Ukranian fauna. Moreover, 93 species from 17 families are the dominant species (at least in one of the urban ecosystems). Among these, eudominants are represented with almost 20 species, but the number of eudomonants did not exceed ten species in separate urban cenoses. Carabidae (80), Staphylinidae (36), Curculionidae (32) and Tenebrionidae (8 species) dominate both, in species composition and abundance. The total part of these groups reached at least 90% of Coleoptera, recorded in urban-cenosis. Separate species of Silphidae, Dermestidae, Elateridae, Chrysomelidae, Leiodidae, Coccinellidae, Nitidulidae, Scarabaeidae, Histeridae and Lucanidae were sporadically usual in most plots. They accounted almost 9% of the total quantity of all beetles in transformed cenoses. Among these, a greater number of species are found within the families of Scarabaeidae (33), Chrysomelidae (16), Elateridae (14), Histeridae (12), Coccinellidae (11) and Nitidulidae (11), Silphidae (6) and Dermestidae (6). The rest of the families are represented with 1–4 species. All beetles registered in herpetobios belong to three groups. Typical inhabitants of herpetobios prevailed (about 200 species from 22 families, at least 90% of all Coleoptera). The proportion of species sporadically associated with herpetobios (more than 40 species from 10 families) was about 5% of all beetles. Random components of herpetobios are represented by more than 70 species from 10 families, and their total share did not exceed 3% of all Coleoptera. A preliminary taxonomic review of coleopterofauna was carried out in different urbocenoses. The number of species in urbocenosises ranged from 101 (Forest Park) to 124 (urban parks). In other green plantings of the city, the species diversity reached 105–118 species. The number of dominant beetles in different areas ranged from 37 to 60 species.

<strong>Carbon Stock in Seagrass Meadows of Bintan Island, Riau Archipelago.</strong> Carbon dioxide (CO<sub>2</sub>) is the main component of greenhouse gas that contributes to global warming. About 40 Tt CO<sub>2 </sub>was accumulated in the ocean plays an important role in the oceans’s carbon cycle. The ocean can absorb CO<sub>2 </sub>through photosynthesis by the planktonic community or coastal vegetations (i.e. seagrass and mangrove) to reduce atmospheric CO<sub>2</sub>. As a study case, we assessed Bintan Island that has the extensive area of seagrass meadows. The potential of seagrass meadows, especially in the absorption of CO<sub>2 </sub>can be estimated by determining the carbon stock. The dominant species of seagrass in Bintan Island are <em>Enhalus acoroides</em> and <em>Thalassia hemprichii</em>. The objectives of this study are carbon stock assessment of the sediment and seagrass habitus (i.e above substrate (AS) consist of leave blades and fronds and Below Substrate (BS) consist of roots and rhizomes). We compare carbon stock between AS and BS, as well as between two species. The result of the research show that carbon estimation value in Pengudang Station (PS) (68.398,47 g C/m<sup>2</sup>) is higher than Teluk Bakau Station  (57.763,47 g C/m<sup>2</sup>). The carbon estimation value of <em>E. acoroides</em> is higher that others either in TBS of PS. The carbon stock in BS is higher than AS. While the estimated carbon stock in the sediment in PS was higher than in TBS.
