Bioindicator of the level of destruction of tropical forests and habitats can be seen from the presence of dung beetle. Dung beetle plays an important role in regulating the function of ecosystems. The purpose of this study was to determine the effect of tree shading on the dung beetle diversity in the the Utilization Block of Wan Abdul Rachman Great Forest Park (Tahura WAR). The method used was the trap method. Traps were planted parallel to the soil, then the collected data was analyzed with diversity index (H`), evenness index (E), and abundance index (E). The results found three species of dung beetles, namely Cattarsius mollosus, Onthopagus sp, and Aphodius marginellus. Diversity index of dung beetle in the area with tree shading (H '= 1.09) was greater than without tree shading (H' = 0 ,9). The evennes index (E) and abundance index (R) of dung beetle in the area with tree shading were E = 0.99 and R = 0.66, while without tree shading were E = 0.82 and R = 0.96. Comparison of the diversity of dung beetle in the the area with tree shading and without shading was 21: 8. This means that the dung beetle could maintain a stable population under tree shading. Dung beetle prefers the area with tree shading due to its suitability for the flight activity, suitable habitat condition, and the availability of food sources. The management of Tahura WAR is expected to increase land cover so that the existing ecosystems could remain sustainable. Keywords: biodiversity, dung beetle, Tahura WAR, tree shading

Amphibian is one of important ecosystem component, both ecologicaly and economically. Research about amphibian in Indonesia is still very limited. In Sumatra, one of Indonesia's largest islands, there hasn't been much attention on research about amphibians. This study aimed to compari the diversity of nocturnal amphibians (Ordo Anura) about at Youth Camp on habitat types. This study was implemented at three different types of habitat, (1) forest, (2) plantations, and (3) rivers. The data was collected by visual encounter survey using line transect method. Identification was book using identification guidebook. The data was analyzed descriptively as well as statistically to calculate species richness and shannonwiener biodiversity index and evenness index. There were 105 individuals comprising 15 species of amphibians and 5 families: Bufonidae 3 species, Megophrydae 1 species, Microhylidae 2 species, Ranidae 7 species, and Rhacophoridae 2 species. Forest habitat found 8 species, plantation habitat 5 species, and river habitat 7 species. The biodiversity index of amphibian at three habitat being categori and evenness index are forest habitat J=0,695, plantation habitat J=0,578 and river habitat J=0,477. Keywords: amphibians, diversity, Hanura, Youth Camp

Way Kambas National Parklocated inLampung Provinceis habitat for gibbon (H. syndactylus), frugivorous primate which plays a role as seeds dispersal process in tropical rainforests with its activities. Purpose of the research is to determine the gibbon's role as seeds dispersal. It was conducted in August 2012 in the Way Kanan Resort of Way Kambas National Park. The method used is exploration and feces analysis. Based on the research, there are 37 samples of gibbon's feces and 7 spesies of seed plant dispersed by gibbon include Polygonum chinense, Grewia paniculata, Ficus sp, Bouea macrophylla, Dacryodes rostrata, Aporosa aurita, and Aplaia palembanica. Seeds are distributed by gibbon using endozoochory process without destroying seeds and can be dispersed far from the parent trees.Distance of the seed dispersed by gibbons ranges 0-385 meters. Defecation activity of gibbon is done after waking, feeding activity, and when moved to other tree with frequency of defecation between 3-6 times a day. The composition ofgibbon's feces is seeds and leaves. The highest attendance of seeds in feces is Polygonum chinense seeds (42,12%) and the lowest is Aporosa aurita seeds (1,18%). The mean seeds in feces is 7,38 from 273 seeds. Keywords : gibbon, seed dispersal, Way Kambas National Park

Sumatran elephant (Elephas maximus sumatranus) requires mineral salts to the body's metabolic processes which can be obtained from the vegetation feed. Mineral deficiencies in plants causes elephants seek other alternative sources such as lick and eat soil that contains salt. This research was done due to lack information about salting behavior and mineral salt content in the saltlicks. The aims of these research were to analyze the salting behavior of Sumatran elephants and to find out mineral salt content of the soil in the saltlicks. The research was done on January 2015 in TNBBS Pemerihan Resort. The research methods of salting behavior used descriptive analysis, mineral content analysis used Microwafe Plasma' Atomic Emission Spectrometer (MP-AES) supported by key person interview and literature studies. The results of this study indicate that salting behavior of Yongki (0.08%) of total daily behavior, the source of salt obtained from soil and mud on riparian, cliffs, primary forest, secondary forest and meadow. Salting was done by taking directly using trunk and put into the mouth. The results of the analyzed of mineral salt content in the soil there are Ca (0.190%), Mg (0.013%), K (0.158%). In the mud Ca (0,323%), Mg (0.405%) and K (0.233%). Elephant more prefer to the mud because mineral content in the mud is higher than soil.
