Mangrove gives major contributions to fishery production; however, due to an increasing demand of space for human activities, mangrove area is changed to many forms, such as settlement, industry, and recreation; beside lack of data and information available (biophysics, socio-economic, and culture). These may cause economical and ecological conflicts. This condition is currently happened in Marine Tourism Park of Kupang Bay (MTPKB). Accordingly, this study aims to analyze community structure of mangrove at MTPKB using survey method to observe mangrove vegetation and exploitation impact by community. In this study, 16 species of 9 families were found with categorized density from “rare” (20 individual/hectare) to “dense” (5.450 individual/hectare). The ecosystem was found has low diversity; it was due to high dominant index. Rhyzophora apiculata and Sonneratia alba were found two species which have big role in the marine park© Mangrove memberikan kontribusi yang besar terhadap produksi perikanan; namun, oleh karena kebutuhan manusia yang semakin meningkat, daerah mangrove dirubah menjadi daerah pemukiman, industri, dan rekreasi; di samping kurangnya data dan informasi yang tersedia. Hal ini dapat menimbulkan konflik secara ekonomi dan ekologi. Kondisi ini sedang terjadi di Taman Wisata Alam Laut Teluk Kupang (TWALTK). Oleh karena itu, penelitian ini dilakukan di mana bertujuan menganalisis struktur komunitas mangrove di TWALTK dengan menggunakan metode survei untuk melakukan pengamatan terhadap vegetasi mangrove dan aktifitas masyarakat dalam memanfaatkannya. Dalam penelitian ini ditemukan 16 jenis mangrove dari 9 famili dengan kerapatan terkategori dari ‘jarang’ (20 pohon/hektar) hingga ‘padat’ (5.450 pohon/hektar). Keanekaragaman ekosistem tersebut rendah karena tingginya nilai dominasi. Jenis Rhyzophora apiculata dan Sonneratia alba merupakan jenis yang memberikan pengaruh besar terhadap komunitas mangrove di taman wisata alam laut tersebut©

Semak Daun Island was part of the Kepulauan Seribu which was a marine tourism destination such as snorkeling and diving site. The existence of these activities had been affecting the condition of the biota community that lives in these waters including macroalgae. The condition of macroalgae communities can be observed by abundance, diversity, uniformity and dominance analysis that occur in these communities that are known as the community structure. The purpose of this study was to determine the structure of macroalgae communities (abundance, diversity, uniformity and dominance) in Semak Daun Island. This research results was found 3 divisions, 10 orders, 13 families, 15 genera and 20 species of macroalgae. The abundance of macroalgae ranges from 235 - 782 individuals/100m2, classified as low abundance. Diversity ranges from 0.96 to 1.83, classified as low diversity. Uniformity ranges from 0.4 to 0.71, including the moderate uniformity and Dominance ranges from 0.22 to 0.57 belong to the low to moderate category, with the most dominant species being Galaxaura rugosa. Physics-chemical parameters of water in general are included in the normal range to support macroalgae life. Based on this, the condition of the macroalgae community structure on Semak Daun Island which is in a less favorable condition is likely due to the existence of snorkeling and diving activities by tourists. Keywords: community structure, macroalgae, Semak Daun Island

In the study on the diversity and community structure of Ephemeroptera in the freshwater stream of Chinnasuruli falls on Megamalai hills, a total of 523 specimens belonging to thirteen genera and five families were collected in six month periods. Of the five families, Teloganodidae and Leptophlebiidae exhibited high diversity and Caenidae showed low diversity. Choroterpes alagarensis (Leptophlebiidae) is the most dominant species. Diversity indices such as Shannon and Simpson indices showed that diversity was maximum in November and December and it was minimum in August and January. Canonical Correspondence Analysis revealed that rainfall, water flow, turbidity, and air temperature were the major stressors in affecting the Ephemeropteran community structure.
