The purpose of this research was to know thehabitat and distribution of MarsupialRats (Echymipera rufescens) on Wamar Island (Wangel Village, Durjela Village, Gunung Sembilan and Back of Wamar Village)Aru Island District. The method used for Marsupial Rats was the catching of wild animals and then the animals that have been capturedin the mark and back again, while for the catching of Marsupial Rats was a tool used is a trap.Analysis of distribution of Marsupial Ratsusing Morista Index while to know the habitat of Marsupial Rats using Line Intercept (line transect) method and the printed path from the analysis to know the pattern of distributionused Morista Index. The result of the research showed that the awareness of the pattern analysis of the Marsupial Rats distribution to the four locations including Wangel Village, Durjela Village, Gunung Sembilan and Back of Wamar Village, from the pattern of horizontal distribution of Marsupial Rats that was the same as random with the index values were Wangel Village was 0.067, Durjela Village was 0.067, Gunung Sembilan village was 0,000, and Back of Wamar village was 0,000. So the pattern of distribution on Wamar Island was random with index value of 0.079. Habitat from the Marsupial Rats own were secondary dryland forest and mixed with shrubs which was his habitat while the feed frm the Marsupial Rats was Galoba, Calladium, Sweet Potato, and Bananas.

Mangroves are forests that grow in brackish water and are affected by tides and seawater, and these forests grow specifically in places where there are pavement and accumulation of organic material. The purpose of this research is to identify the types of mangroves and determine the structure of the mangrove community in Lesah Village. This research was conducted from September to October 2019. The method used in this research is the quadrant line transect method. The types of mangroves were identified with identification books. Community structure data taken are density, frequency, dominance and important value index (IVI) and then analyzed with Microsoft Excel program. Based on the results of the research, there are 2 types of mangroves found in the research location, Rhizophora stylosa and Sonneratia alba. The highest density value (0.122 ind / m2), relative density (81.88%), frequency types (1), relative frequency (50%). Closure types (1.83 m2), types of relative closure (50.18%), the highest important value index at the research site was (182.12%). The results of the mangrove ecological index data analysis for the diversity index value (0.51), dominance (0.73). Keywords: Structure Community, Mangrove, Lesah Village.

Density and Flock Size of the Raven (Corvus corax) In the Orawa - Nowy Targ Basin During Non-Breeding Season During the 2002/2003-2004/2005 non-breeding seasons the density of the Raven in the open habitats of the Orawa - Nowy Targ Basin was studied by line transect method. The results were analysed in four periods (autumn, early winter, winter and early spring). The median density of Ravens did not differ significantly between individual periods and was respectively: 3.5, 3.8, 4.8 and 3.8 indiv. / 10 km. Number of birds during particular controls varied from 1.0 to 24.8 indiv. / 10 km. However, while excluding flocks, the median density of single individuals and pairs of the Raven was considerably lower and in subsequent periods reached respectively: 2.2, 2.4, 2.2 and 1.7 indiv. / 10 km. Flock size did not differ significantly between individual periods. Single individuals and, less often, groups of two birds were recorded mostly. Small (3-5 indiv.) and medium (6-15 indiv.) flocks were recorded rarely and large flocks (16 indiv. and above) - only exceptionally. The high density and strong fluctuations of abundance of Ravens were determined by flocks presence, which was probably linked to irregular occurrence of food resources.

Background: Decreasing of sea cucumber resources on numbers and size of fishing capture in Negeri Porto waters influenced its community structures. Further, water environment steadiness will questionable. For this reason, study was done to analyzed community structures of sea cucumbers include of numbers species found, density, potency, species presence frequency, distribute pattern, ecology index and environment measurement. Method: Research done on February to May, 2008 at Negeri Porto used Line Transect Method. Result: showed there were eight species of sea cucumbers found (potency as much as 12.286 individuals). Bohadschia marmorata got highest in numbers species found, density, potency and species presence frequency. There were three distribute pattern of sea cucumbers found wich are uniform, random and group. Conclusion: Sea cucumbers diversity was in lower, species are closed to compatible. B. marmorata and Holothuria edulis are tends to dominate this water. Environment factors such temperature, pH, salinity, DO, turbidity, current and sediment distribute showed that Porto waters was suitable to sea cucumbers growth.

Abstract : Orangutan is classified as an endangered species. Forest clearance for a variety of purposes and functions over the region led to the limited habitat for orangutans. Orangutans habitat is fragmented into several regions led to the survival of a population of a species depends on habitat conditions. Performing a nest survey is important to give a deeper understanding of the ecology and help determine the best protective management measures. We provide basic data of orangutan density and orangutan nesting characteristics in protected forest area Sibongkaras village. This study was conducted in April 2019 until June 2019 in protected forest area Sibongkaras village, Pakpak Bharat. Tracking begins with observed the presence of a nest based on a purposive sampling method. And data retrieval was done by line transect method. Data analyzed at Universitas Nahdlatul Ulama Sumatera Utara. Our result showed that the orangutan population density was 0.0072 individuals/km2 or 0.72 individuals/ha. The dominant position of the nest is in a position which is a position I nest close to the main stem of the tree with the nest number 13 (43.3%). Generally, the nest is found at an altitude of  >15 meters with a sum of 27 nests (90%).Abstrak : Orangutan diklasifikasikan sebagai spesies yang terancam punah. Penebangan hutan untuk berbagai tujuan dan fungsi di kawasan tersebut menyebabkan terbatasnya habitat orangutan. Habitat orangutan yang terfragmentasi menjadi beberapa wilayah menyebabkan kelangsungan hidup suatu populasi suatu spesies tergantung pada kondisi habitat. Melakukan survei sarang penting untuk memberikan pemahaman yang lebih dalam tentang ekologi dan membantu menentukan langkah-langkah manajemen perlindungan terbaik. Kami menyediakan data dasar kepadatan orangutan dan karakteristik sarang orangutan di kawasan hutan lindung Desa Sibongkaras. Penelitian ini dilakukan pada bulan April 2019 hingga Juni 2019 di kawasan hutan lindung Desa Sibongkaras, Pakpak Bharat. Pengamatan dimulai dengan mengamati keberadaan sarang berdasarkan metode purposive sampling. Dan pengambilan data dilakukan dengan metode transek garis. Data yang diperoleh di analisis di Universitas Nahdlatul Ulama Sumatera Utara. Hasil Penelitian kami menunjukkan kepadatan populasi orangutan di 0,0072 individuals/km2 atau 0,72 individu / ha. Posisi sarang yang dominan adalah pada posisi sarang yang berada di posisi paling dekat dengan batang utama, dengan jumlah sarang 13 (43,3%). Umumnya sarang ditemukan di ketinggian > 15 meter dengan jumlah 27 sarang (90%).
