	abstract = {Kumu River is one of the river in Rokan Hulu Regency, Riau Province, Indonesia. Many people use it as water resources like bathing, washing and transportation. But human activities has caused impact to this river even pollution that caused by changing into agriculture and people settlement that have affected many organisms around that can be used as indicator, one of them is gastropods. This study was conducted to determine the diversity of gastropods in Kumu river from April to June 2013. The samples were taken from three different stations, those are upper stream, middle stream and down stream. And from every station, samples collecting was done about 10 times by using square 1 x 1 metre randomly. Everything in the square was putting into a bucket and will be filtered at the edge of the river. Samples were obtained, inserted into sample bottles that contains alcohol 70\% and marked. Samples that have been preserved, and then sorted, identified and counted the number of individuals of each species, and data analysis. Data analysis, among others, to calculate the diversity index, evenness index, and dominance index in the Laboratory. From the analysis, we found 3 families, 4 spesies and 181 individual total of gastropods. The diversity index ranged from 0.41 to 1.359, evenness index ranged from 0.592 to 0.981 and the dominance index ranged from 0.264 to 0.755. Pomacea canaliculata was the most dominant gastropods from all stations. And can be concluded that the diversity of gastropods in Kumu River is at low category.},

	abstract = {ABSTRACT Lake Towuti is a tectonic-oligotrophic  located in Malili Complex, South Sulawesi. This lake sustains the life of several endemic fish resources, as well as utilized for various human purposes i.e. hydroelectric power plant, capture fishery, navigation, ecotourism and source of water for domestic uses. On the other side of this lake also supports the life of the kinds of resources, especially fish species that are endemic genetic resources that can be utilized surrounding communities. Therefore, the diversity of fish resources in these waters should be protected from a variety of activities that can reduce the population of the fish resources. The aim of research is to know the distribution and habitat of endemic  fish biodiversity in ancient Lake Towuti as a basic for formulating the zoning criteria of endemic species in Lake Towuti. This research was conducted in Lake Towuti from June to October 2009 at Tominanga, Manu Cape,  Loeha Island, Hola-hola downstream, Kawatang downstream, Beau and Bakara Cape. Fish sampling using experimental gill net with four mesh size. The connection of the fish resources with environmental parameters were analyzed using principal components analysis. Habitat characteristics viewed from the environmental factors that are important for fishes were high in pH, total phosphorus, total organic matter and suspended solid; substrate type is silt and low clay and sand; high riparian vegetation cover of the group Ottelia mesenterium and Cyperus. Stations that have high species diversity for fishes were Tominanga and Hola-hola downstream. Keywords: distribution, habitat, fishes, ancient Lake Towuti },

	abstract = {Cerambycids have an important function in the ecosystem, i.e. bioindicators, saproxylic, pollinators, and as food of other organisms. Land cover changes due to land use can disrupt the natural balance of the ecosystem, which resulted in the decrease of cerambycids diversity. Species diversity of cerambycids in four land types, i.e. jungle rubber, rubber plantations, oil palm plantations, and felled jungle rubber were studied. Collections of cerambycid spesies were done by Artocarpus heterophyllus branch trap. Sample collections were done on days  4, 7, 10, 13, 16 after the artocarpus traps were set up. In the four land use types in Jambi province, we collected 72 species of cerambycids. Cerambycids collected in the jungle rubber, rubber plantation, oil palm plantation, and felled jungle rubber were  42, 39, 16, and 28 spesies, respectively. Cerambycids diversity was highest in jungle rubber (H{\textquoteright}= 3.23), followed by rubber plantation (H{\textquoteright}= 2.67), felled jungle rubber (H{\textquoteright}= 2.38), and oil palm plantations (H{\textquoteright}= 2.01). Highest similarities of cerambycid communities occured in the rubber plantation {\textendash} felled jungle rubber (51.249), followed by jungle rubber - rubber plantation (50.005), rubber plantations - oil palm plantations (43.467), oil palm plantation - felled jungle rubber (42.409), and jungle rubber - oil palm plantations (35.264). The lowest similarity occured in jungle rubber {\textendash} felled jungle rubber (34.796). The number of species and individual of cerambycids collected on day 7 was higher than that on days 4, 7, 10, 13, 16, respectively.},
