Abstract

Bogani Nani Wartabone National Park is a tropical low land rain forest. This region has high diversity of arthropods, i.e. spider. The aims of this study was to analyze the Community structure of spiders of spiders (Arachnida: Araneae) in various types of habitat at Bogani Nani Wartabone National Park North Sulawesi. Sampling was carried out at three habitat types, namely primary, secondary, and farm. The research was conducted from March to May 2014 by using pitfall trap (to collect spiders that move on the ground) and sweep net (to collect the spideron vegetation canopy). The number of spiders obtained during the study of was 1267 speciments. The specimens collected are consists 15 families, 71 genera, and 129 morphospecies. The Family which most individual abundance is family Tetragnathidae and the least was Ctenizidae. Salticidae were the most common family of species (30 species), while the least were Agelenidae, Ctenidae and Ctenizidae where each family has one species. Abundance, richness, diversity and evenness of species was higher in the farm, while the lowest in the secondary forest. The highest similarity index of spider communities was between primary forests and secondary forests. The results of this research can be used as a diversity database of spiders for conservation strategies in North Sulawesi.

Abstract

A study on mapping of distribution and population of Sulawesi crested black macaques (Macaca nigra) has been carried out to evaluate the current condition of distribution and density. This research was conducted from January to November 2009 at 24 locations in North Sulawesi Province. Determination of  M. nigra distribution was based on the information provided by people surrounding the sites and field observation. Line transect was used to evaluate the density of the monkey with the length based on the habitat condition and the width was 100 m. The results showed that monkeys were not found at all of the locations and based on categories, high density of monkey was only found at Tangkoko-Batuangus Nature Reserve  Two serious problems responsible to monkey population decreasing were hunting for consumption and habitat destruction. It can be concluded that distribution of M. nigra in North Sulawesi is meta-population and the current status of the species as critically endangered is accepted; the conservation of this species depends on the active management and terminating the factors of population decreasing.

Abstract

Pseudagrion pilidorsumis1of over 140 species of Pseudagrion (in thefamily Coenagrionidae), the largest genus of damselfly. This species exhibits dimorphism due to the different body colorations of males and females, making them difficult to distinguish from other congeneric species. This study analyzed thecytochrome C oxidase subunit I (COI) gene sequence of P.pilidorsum found in Bogani Nani Wartabone National Park (North Sulawesi) and compared it with other sequences of P. pilidorsum from distinct geographical locations in Asia. The COI gene for the Sulawesi specimen was amplified using the universal primer pair LCO1490 and HCO2198. A sequence homology search was conducted through BLAST. Multiple sequence alignment was executed using CLUSTALO (1.2.1). A phylogenetic tree was constructed using the Neighbor-Joining method, and genetic distance was calculated using the Kimura 2-parameter. The COI gene sequence of the Sulawesi specimen lies in the range of 83.99-89.10% with other P. pilidorsum deposited at Gen Bank, namely KF369526 (Sarawakspecimen), AB708543, AB708544, and AB708545 (Japan specimens). The genetic distance falls in the range of 0.146-0.149 between the Sarawak specimen and the Japan specimen; 0.122-0.125 between the Sulawesi and Japan specimens; and 0.185 between the Sulawesi specimen and the Sarawak specimen. It can thus be inferred that the Sarawak and Japan specimens may not belong to the same species; the Sulawesi and Japan specimens may not belong to the same species; and the Sarawak specimen and Sulawesi specimens might be placed in different genera.

MAKROZOOBENTOS SEBAGAI INDIKATOR BIOLOGIS DALAM MENENTUKAN KUALITAS AIR SUNGAI RANOYAPO, MINAHASA SELATAN, SULAWESI UTARA ABSTRAK Sungai Ranoyapo merupakan sungai terpanjang di Wilayah Minahasa dengan panjang sekitar 60, 5 Km. Sungai Ranoyapo adalah sungai utama  DAS Ranoyapo yang memiliki luas sekitar 87,154 Ha.  Sungai Ranoyapo melintasi kawasan pertanian, perkebunan, permukiman penduduk, dan industri. Limbah yang berasal dari kawasan tersebut mempengaruhi kualitas air Sungai Ranoyapo. Makrozoobentos dapat digunakan sebagai parameter biologi dalam menentukan kondisi sungai karena hidupnya relatif diam di dasar sungai.   Penelitian ini bertujuan untuk menentukan kualitas air Sungai Ranoyapo berdasarkan indeks keanekaragaman makrozoobentos.   Penelitian dilakukan pada musim hujan yaitu Januari-Maret 2013.  Lokasi penelitian ditentukan dari bagian hulu, tengah dan hilir sungai dengan 3 ulangan di tiap lokasi.   Kualitas air Sungai Ranoyapo ditentukan berdasarkan indeks keanekaragaman makrozoobentos dari Shannon Wiener (H’) menurut kriteria                   Staub et al (1970).  Makrozoobentos di Sungai Ranoyapo terdiri dari 3 Filum, 5 Kelas, 13 Bangsa, 21 Suku, dan 23 Marga. Indeks keanekaragaman makrozoobentos dari Stasiun I (hulu), Stasiun II (tengah) dan Stasiun III (hilir) yaitu 2,43; 2,06; dan 1,77. Kualitas air Sungai Ranoyapo di Stasiun I dan di Stasiun II telah tercemar ringan dengan indeks       H’: 2,0 – 3,0 (H’>2).   Kualitas air Sungai Ranoyapo di Stasiun III telah tercemar sedang dengan indeks     H’ sekitar 1,0 – 2,0 (H’ <2). Kata kunci: Sungai Ranoyapo, kualitas air, pencemaran air, keanekaragaman makrozoobentos MACROZOOBENTHOS AS BIOINDICATOR IN DETERMINING WATER QUALITY OF RANOYAPO RIVER, SOUTH MINAHASA, NORTH SULAWESI ABSTRACT Ranoyapo River is the longest river in the Minahasa Region with its length of  60.5 Km. Ranoyapo River is the main river watershed Ranoyapo which its area of 87.154 ha. Ranoyapo River crosses agricultural, plantation, resident, and industry areas. Waste originated from those areas will affect water quality of Ranoyapo River. Macrozoobenthos can be used as a biological parameter in determining the condition of the river because they relatively slow move on the riverbed. This study aims to determine the water quality of the River Ranoyapo based on biodiversity index of macrozoobenthos. The study was conducted during the rainy season i.e. from January to March 2013. Three locations were chosen from upstream, midstream and downstream river with 3 replications in each location. The quality of Ranoyapo River was determined by the biodiversity index Shannon Wiener (H') of macrozoobenthos using classification of Staub et al (1970. Macrozoobenthos of Ranoyapo River consisted of 3 Phyla, 5 Classes, 13 Orders, 21 Families, and 23 Genus. Biodiversity index (H’) of macrozoobenthos from up (Station I), middle (Station II) and downstream (Station III) respectively were 2.43; 2.06, and 1.77. The quality of Ranoyapo River at up and middle were lightly polluted with index H’: 2.0 to 3.0 (H '> 2.0) and at down was moderately polluted with index H ': 1.0 to 2.0 (H' <2).
