<p>Ornitholog past studies focused on the natural environment, now they have a lot of studying birds in urban areas. In Java inhabited by 368 species of birds recorded settler and nomad 126 species of birds , but it is not known how many types of them which now lives in urban areas. Bird diversity in the city of Yogyakarta, which was founded in 1755 and now has a population of 388 627 inhabitants, is unknown. The research objective was to determine the diversity, the proportion of community based on the type of bird feed (guild) and bird species nest in the city of Yogyakarta. The study was conducted during the day in April-May 2013 in the 7 villages of 3 subdistricts in the city center Kraton, Gondomanan and Ngampilan. Data colection used Point of Abundance Index method, and analyzed by the Shannon Diversity Index - Wienner ; types of feed directly observed and are determined based on a review of literature and the proportion of bird communities based on guild were analyzed with the use of modified importance value index ; nest observed directly and analyzed descriptively. The results showed in Yogyakarta were found 28 species of birds covered in 11 familia with moderate levels of diversity (diversity index 2.2) and 5 types including protected status that is Anthresep malacensis, Nectarinia jugularis and Arachnothera longirostra (Fam.Nectariniidae), Alcedo atthis and Halcyon cyanoventris (Fam. Alcedinidae). Composition based on the guild type is graminivorous (46.58 %), nectarivorous <br />(46.51 %), nectrivoous (5.53 %), frugivorous (1.08 %), and 0.29 % piscivorous, and was found at least nine species of birds that nest in the city of Yogyakarta. Therefore, birds in the city of Yogyakarta is quite diverse and populated several protected species, it is necessary to research on biological properties, especially the origins, patterns of reproduction and structural adaptation and behavior.</p><p><br /><strong>Keywords</strong> : City of Yogyakarta, birds, diversity index, type of feed, nest</p>

Abstract. Izzati U, Hasibuan HS. 2019. Riparian tree and bird diversity in Cisadane River, South Tangerang City, Indonesia. Biodiversitas 20: 595-603. Riparian is a riverbank area that has unique characteristics. It is a combination of terrestrial with aquatic habitats so that riparian ecosystems have high biodiversity values. Riparian is included in a protected area that is naturally designated for vegetation, but in reality, riparian areas, especially in urban areas, have a lot of conversion of land functions by humans so that it can disrupt diversity of tree and bird species. This study aims to identify the diversity of tree and bird species and the correlation between the two. Riparian length of Cisadane River, South Tangerang City is 20.15 km. The method used was plot line with size of 20 m x 20 m for tree data and line transect for bird data by systematic sampling with a random start then analyzed using Shannon Wiener index. The results obtained were found 22 tree species included in 11 families with species diversity index (H') of 2.707 and 40 bird species belonging to 25 families with species diversity index (H') of 2.794. The diversity of tree and bird species is classified as medium. The results of the analysis using the Pearson correlation between the diversity of tree with bird species obtained that there was no relationship between the two. Based on these results, riparian zones in urban areas need to be maintained and improved in quality so that the diversity of tree and bird species increases so as to create a stable ecosystem.

Abstract Urbanization in cultural landscapes generally tends to select for omnivorous, granivorous, and cavity/hole nesting bird species in green urban areas. Studies on bird diversity in the cities are important to better understanding to the ecology of urban and sub-urban landscapes. The aim of this study was research on bird diversity in urban parks in Olomouc city in order to brief comparison with bird diversity in hardwood floodplain forest habitats based on our older above-mentioned study. Bird diversity in urban parks was very similar to the bird diversity in some localities of floodplain forests from the Czech Republic. Comparison between urban parks and hardwood floodplain forests in the vicinity of the city revealed a high similarity of alpha-diversity and diversity indexes. These results indicated that large urban parks have nearly the same importance for bird diversity such as managed hardwood floodplain forests. Results highlighted an importance of urban green areas for biodiversity maintaining in European cultural landscapes.

There exists limited information on biodiversity including avifaunal diversity and habitat condition in community forests (CF) of Nepal; thus we aimed to fulfill such gaps in Tibrekot CF of Kaski district. We used the point count method for assessing bird diversity and laid out a circular plot size of radius 5-m within 15-m distance from each point count station for recording the biophysical habitat characteristics. Bird species’ diversity, richness and evenness were calculated using popular indexes and General Linear Model (GLM) was used to test the respective effect of various biophysical factors associated with the richness of bird species. In total, 166 (summer 122, winter 125) bird species were recorded in 46 sample plots. The Shannon-Wiener diversity index was calculated as 3.99 and 4.09, Margalef’s richness index as 16.84 and 17.53 and Pielou’s evenness index as 0.83 and 0.84 for summer and winter, respectively. The influencing factors for richness of bird species were season (χ21, 90= 112.21; P= 0.016) with higher richness in the summer season and low vegetation cover (χ21, 89= 113.88; P= 0.0064) with higher richness in lower percentage cover. Thus, community managed forest should be protected as it has a significant role in increasing bird diversity, which has potential for attracting avifaunal tourism for the benefit of the local communities.

O objetivo deste estudo foi comparar a composição florística e a estrutura fitossociológica dos bosques de manguezais de áreas urbanas em Aracaju, estado de Sergipe, com diferentes tempos de regeneração e intensidades de impacto antrópico. Para o levantamento fitossociológico, foi adotado o método de parcelas múltiplas, sendo seis ou sete parcelas distribuídas equitativamente em dois transectos paralelos em quatro bosques de manguezais nos bairros 13 de julho, Porto Dantas, São Conrado e Mosqueiro. Destes, somente o bosque do Mosqueiro não apresentava tensores antrópicos contínuos como descarga de esgotos domésticos, retirada de madeira ou contribuição alóctone de sedimento. Para caracterizar a estrutura dos manguezais foram calculados os parâmetros densidade, frequência, dominância e o índice de valor de importância de cada espécie. Procedeu-se com a comparação estatística entre os bosques avaliados pelo teste de Kruskal-Wallis quanto a densidade geral e por espécie, diâmetro e altura geral dos indivíduos. Foram identificadas quatro espécies: Laguncularia racemosa, Avicennia schaueriana, Rhizophora mangle e Conocarpus erectus, que apresentaram diferenças de abundância e dominância entre os bosques analisados. De maneira geral, L. racemosa foi à espécie mais abundante e dominante nos bosques mais impactados, porém no bosque do Mosqueiro, R. mangle foi a mais dominante. Não houve diferenças significativas na densidade, diâmetro e altura geral dos indivíduos, porém a densidade de A. schaueriana e R. mangle diferiu entre os bosques. Em relação à altura, os bosques da 13 de julho e São Conrado apresentaram os maiores valores, ainda que possuíssem o menor tempo de regeneração pós-distúrbios.Phytosociology of mangroves in urban areas: a case study in Aracaju city, Sergipe stateA B S T R A C TThe aim of this paper was to compare the floristic composition and the phytosociological structure of the mangrove forests in urban areas with different levels of regeneration and intensities of anthropic impact. The study was performed in the municipality of Aracaju, Sergipe state, Brazil Northeast. For the phytosociological survey, the multiple plots method was adopted; so six or seven plots were equally distributed in two parallel transects in four mangrove forests in the neighborhoods 13 de Julho, Porto Dantas, São Conrado and Mosqueiro. Of these, only the Mosqueiro mangrove did not have continuous anthropic tensors such as discharge of domestic sewage, removal of wood or allochthonous contribution of sediment. To characterize the structure of the mangroves, the parameters density, frequency, dominance and the importance value index for each species were calculated. Statistical comparison was made among the mangroves evaluated using the Kruskal-Wallis test between general density and by species, diameter and general height of individuals. Four species were identified: Laguncularia racemosa, Avicennia schaueriana, Rhizophora mangle and Conocarpus erectus, which showed differences in abundance and dominance between the mangroves evaluated. In general, L. racemosa was the most abundant and dominant species in the most impacted mangrove, but in the Mosqueiro mangrove, R. mangle was more dominant. There were no significant differences in the density, diameter and general height of the individuals; however the density of A. schaueriana and R. mangle differed between mangroves. In relation to height, the forests of 13 de Julho and São Conrado presented the highest values, even though they had the shortest time of regeneration after disturbances.Keywords: ecotone, mangrove, forest structure, coastal zone, Brazil northeast.

Abstract. Ardiyaningrum I, Budiastuti MTS, Komariah. 2021. Short Communication: Species composition and diversity of vegetation in dryland agricultural landscape. Biodiversitas 22: 65-71. Drylands are a part of the terrestrial ecosystems with a relatively larger area compared to wetlands. Selo has dryland with steep slopes and high rainfall, resulting in relatively high soil erosion. The land use in this sub-district is dominated by plantations and agriculture, with conditions that have not been fully balanced by trees as a means of controlling erosion and supporting vegetation diversity. Therefore, studies on biodiversity are important as an indicator of dryland sustainability, especially in terms of soil and water conservations. This research aimed to study the species composition and diversity of vegetation in the dryland agricultural landscape in Selo Sub-district, Boyolali District, Central Java Province, Indonesia. Vegetation analysis was performed by using the quadratic sampling technique for tree category, pole category, sapling category, and seedling categories. The results indicated that Fabaceae had the highest number of species. Tree species with the highest Importance Value Index were Toona sureni, Artocarpus heterophyllus, and Casuarina junghuhniana, respectively. The Shanon-Wiener Diversity Index showed that the vegetation at tree, pole, and sapling stages had a moderate diversity, and seedling-stage vegetation had a low diversity.

Diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra, Indonesia. Biodiversitas 20: 1215-1221. The purpose of the study was to analyze the flora diversity and characteristics of mangrove vegetation in Pulau Rimau Protection Forest, Banyuasin District, South Sumatra. Data collected were the number and girth diameter of mangrove tree species, and aquatic ecology parameters using transect method. The sample plots size were 2m×2 m; 5m×5 m; 10m×10 m; for seedling, sapling, and tree, respectively. The observation plots were arranged in a row of 120 m length on two sides of the forest edge, namely Calik Riverbank and Banyuasin Riverbank. Data were analyzed using importance value index (IVI), Simpson’s diversity index and Sørensen’s community similarity. The study revealed that there were differences in mangrove characteristics in two study sites. There were 57 plant species identified inside and outside sample plots, but only 15 species (26.32%) among them were categorized as true mangrove species. Inside the sample plots, there were 11 and 10 mangrove tree species recorded on the Calik Riverbank and Banyuasin Riverbank, respectively, but only 7 species among them were found in both sites. The mangroves on Calik Riverbank were dominated by Nypa (IVI 53.59%) and Bruguiera (51.12%), while those on Banyuasin Riverbank were dominated by Sonneratia (66.91%) and Avicennia (51.73%). The Simpson’s diversity index for Calik Riverbank and Banyuasin Riverbank was 0.82 and 0.78, respectively, whereas the Sørensen’s coefficient of community between the two sites was 0.67.

Abstract. Iskandar BS, Iskandar J, Partasasmita R. 2019. Hobby and business on trading birds: Case study in bird market of Sukahaji, Bandung, West Java and Splendid, Malang, East Java (Indonesia). Biodiversitas 20: 1316-1332. Bird species have various ecological and socio-economic-cultural functions for the human being. Ecologically, birds have beneficial functions in the ecosystem, such as helping plant pollinators, spreading plant seeds, participating in controlling agricultural pests, and monitoring environmental changes. Meanwhile, bird functions for the social-economic and culture of the community among them are known as sources of protein food, mystical functions, sources of material stories, sources of inspiration to make songs, craft materials, the source of gene pool, and become pets and trade animals. With the rise of the urban population hobby of raising birds and also the development of various bird contest activities in the urban, causing of the bird trade is very widespread in urban areas, such as in bird markets. In some cities in Indonesia, various bird markets have been popularly known for a long time. This study aimed to elucidate species diversity, folk classification, bird populations, bird prices, constraints to bird trade, and the positive and negative effects of bird trade in the urban bird market. The research method used a mixture of qualitative and quantitative methods with the ethnoecological approach. The results of this study showed that from a survey of 60 bird traders in the bird market of Sukahaji, Bandung, and Splendid, Malang, a total of 160 bird species, representing 38 families were documented. Among them, 10 species representing 7 families recorded as protected bird by law in Indonesia, based on recent government regulation of the Minister of Environment and Forestry of Republic of Indonesian No.106/MENLHK/SETJEN/KUM.1/12/2018. A total of 2,950 individuals were recorded in Sukahaji; while in Splendid were recorded 3,558 individuals. Prices of birds that are traded varied greatly depending on the species and characteristics of birds. It has been revealed that bird trade in the bird market has been various economic benefits for many people. However, due to the bird trade in bird markets in the city which has not been properly managed, the sustainability system of the bird trade in the city is very alarming caused of many factors, including decreasing of bird population over time in rural ecosystem as main supply of urban bird trading in the bird markets. Therefore, bird trading in the bird markets must be properly managed based on the sustainable development program concept, namely pro-economic, pro-social, and pro-environment.
