The waters of Tongkaina, which are part of northern Manado's waters, are known to have mangrove, seagrass, and seaweed ecosystems. Therefore efforts are needed to manage the population and diversity of echinoderms in these waters. Echinoderms' ecology has an essential role in maintaining the marine ecosystem's balance, which plays a role in recycling nutrients. This study aimed to determine diversity, species density, species relative density, species frequency, species relative frequency, dominance, and the index of importance of Echinoidea and Asteroidea's species in the waters of the Tongkaina Village and their density. The method used in this research is the quadratic line transect method. First of all, the survey was conducted to the sampling site's location in the coral reef flats of Tongkaina Village's waters, including Tongkaina beach and Bahowo beach, before operating the sampling. Then the observation stations were determined, namely Tongkaina waters (near Batu Meja) and Bahowo waters. The quadratic line transect method is used in this research. Species of class Echinoidea and Asteroidea in the quadrat were recorded among the total of individuals, and the species is documented. This study's results indicate that six species were found, including the survey, and five species were found based on the line transect method with 182 individuals. Including Asteroidea 85 Individuals and Echinoidea 99 Individuals. Value of Diversity at station 1 has a value of H '= 1.170 with a dominance of C = 0.364, while at Station 2 has a value of H' = 1.232 and dominance value of C = 0.316. the highest density in Station 1 is Diadema savigny 1.967 ind/m2 relative 50.86%, and Linckia laevigata with the highest frequency Fi = 0.533. The highest important value index is Diadema savigny, with a value of 81.09%, while at station 2, the Protoreaster nodosus has the highest value of important value index with a value of 87.51%. These species also have the highest density of 0.933 ind/m2 and a relative number of 41.79%.Keywords: Tongkaina, Echinoderm, Line Transect Quadrat Method, Asteroidea, Echinoidea, Coral Reef Flat

Tapanuli Orangutan nests are the focus of this research. This research is aimed to know the variety of constituents plant the nests of tapanuli orangutan (Pongo tapanuliensis), to know the kind of the most dominant plant to construct the nests by Tapanuli orangutan (Pongo tapanuliensis), the composition of constituents the nests of tapanuli orangutan (Pongo tapanuliensis) in North Tapanuli. This research was primery forest Batang Toru National Park. This research using line transect method with 4 transects (transects I, II, III, IV) were used to observe the nest tree and the nest constituent of Tapanuli orangutan. This research results is there are 5 species of of constituents plant the nests with quantity 14 nests. The most dominant tree nest is Syzygium sp (43%), Plant constituent orangutan nests also use the leaves of the Shorea hopeifolia (94.1%), as well as branches of Palaquium gutta (6.6%).

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.

Essential Contribution

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.  It shares its border with 22 of 37 villages surrounding the national park.  Understanding their existence in the wild is a priority, and  wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.  Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.  Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort.  Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.  Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.  Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

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.
