Abstract

Reproduction of Endemic Fish Butini (Glossogobius matanensis) Based on Depth and Time in Towuti Lake. Butini fish (Glossogobius matanensis) belonging to the Gobiidae family and is one ofendemic fish in Towuti Lake and classified as demersal fish. Fishing activities and habitat quality changes tend to reduce butini stocks in Towuti Lake. Therefore, it needs to be protected of stocksfor sustainability. This research is to determine reproduction of endemic fish based on depth and time as basic data for the effort of conservation and domestication. Gonad maturity that was analyzed histologically obtained five maturity stages. Based on the diversity of egg size, especially in the gonad maturity stage (IV), it is indicated that butini fish are classified as partial spawner. Male and female fish gonad mature (50%) at 36.22 and 31.43 cm total length, respectively. October and March, an estimated spawning peak of butini fish in Towuti Lake held this month at a depth of 150m and 200 m. Fecundity of butini fish in gonad maturity stage (III and IV) between 11184-66305 eggs and 14922-81522 eggs, respectively. The highest mean of fecundity there in October (56,907 eggs) and the lowest was found in July (25,447 eggs). Fecundity of fish at 25 m-200 m depths ranging from 30.778-35.329 eggs.Keywords: Reproduction, endemic fish, Glossogobius matanensis, depth and time, Towuti Lake

Abstract

Tree architectural model is basically a tree construction as a result of meristematic growth pattern. Tree architectureis closely associated with water and soil components, i.e. rainfall, throughfall, stem flow, infiltration, surface run-off,and erosion. For Altingia excelsa (Rasamala) plots, the results showed that the daily average of the rainfall intensityobserved was 9.67 mm, stem flow 0.03 mm, canopy throughfall 5.43 mm, infiltration 0.51 ml/mm2/second,surface run-off 3.45 mm, and erosion 5.66 kg/m2. For Schima wallichii (Puspa), the daily average of rainfall was9.67 mm, stem flow 0.04 mm, canopy throughfall 4.02 mm, infiltration 0.49 ml/mm2/second, surface run-off 8.18mm, and erosion 12.71 kg/m2. Compared to A. excelsa, S. wallichii significantly had larger values in someparameters measured, i.e. stem flow, surface run-off, and erosion, indicating that on land sopes of 70% of theMount Gede Pangrango National Park, individual plants of S. wallichii seemed to be well adapted. However,individuals of A. excelsa possessed a more spreadly branching model, larger vertical width, denser canopy, andskewed bark channels capable for slowing down the stem flow and canopy throughfall. Consequently plants of A.excelsa would generally be able to hold and conserve water and soil better than S. wallichii plants.Keywords: Tree architectural model, stem flow, throughfall, surface run-off, infiltration, erosion

Abstract

ABSTRACTTarsier (Tarsius spp.) are the smallest primates in the world. Currently there are 10 species, of which 9 species are distributed in Indonesia and 8 species of them are endemic to Sulawesi. Morphologically  the Sulawesi spesies are almost similar. This research is aimed to identify the use of Cytochrome Oxidase I (COI) gene as a genetic marker on Tarsius spp. for conservation purposes. Sixteen individuals consisted of 10 Tarsius bancanus, 4 Tarsius sp., 1 Tarsius wallacei , and 1 Tarsius sangirensis were collected from various places and analysed using COI gene. The results showed  there were 238 different sites of nucleotides and 159 sites of amino acids from the total amount of 838 bp. The genetic distance by Kimura-2 parameter showed the highest value was 26% while the lowest was 0%. The average genetic distance was 11,5%. Phylogenetic tree constructed by Neighbour-Joining method based on nucleotides sequence showed that the COI gene could be used as a genetic marker to differentiate among Tarsius spp. but could not be used as a clear marker for tarsiers in Sulawesi. Based on the analysis, there is a high value of genetic variation among Tarsius spp. with much lower genetic variation in Western Tarsier population compared to Eastern Tarsier. Keyword: Genetic marker, tarsier, COI, DNA mitochondria, conservation

Abstract

ABSTRAKHubungan Kekerabatan Kakatua (Aves: Psittaciformes) Berdasarkan Sekuen DNA dariIntron ke Tujuh dari Gen ?--fibrinogen. Hubungan kekerabatan diantara burung kakatuamasih menjadi perdebatan, khususnya menyangkut posisi dari Nymphycus hollandicus. Intronpada gen ?-fibrinogen telah diketahui berguna untuk mempelajari filogeni dari beberapakelompok burung, oleh karena itu penelitian ini menggunakan sekuen DNA dari intron ketujuhpada gen ini (?-fibint7) untuk mengkonstruksi filogeni dari enam genus (Cacatua,Callocephalon, Eolophus, Calyptorhynchus, Probosciger, dan Nymphicus) yang terdapat didunia berdasarkan analisis neighbor-joining (NJ) and maximum-parsimony (MP). Ditemukanbeberapa indel (insersi-delesi) pada sekuen DNA dari â-fibint7 kakatua, sehingga panjangsekuen DNA bervariasi diantara taxa-taxa yang diteliti. Tidak terjadi saturasi antara substitusi transisi dengan transversi, dan juga antara transversi dengan jarak genetik. Tribe Cacatuiniyang terdiri dari tiga genus Cacatua, Callocephalon, dan Eolophus bersifat monophyletic.Meskipun hubungan diantara spesies dari genus Cacatua tidak terungkap dengan jelas, tetapiC. alba, C. galerita, C. goffini, C. sanguinea, C. moluccensis dan C. sulphurea berada didalam satu group, dan C. leadbeateri relatif terpisah dari species-species congeneric lainnya.Callocephalon secara filogenetik terpisah jauh dari genus-genus lainnya pada tribe Cacatuini.Tribe Calyptorhyncini yang terdiri dari Probosciger dan Calyptorhynchus adalah paraphyletic.Calyptorhynchus tampak monophyletic. Nymphicus (tribe Calopsittacini) menjadi cladebasal dari kakatua.Key words: Kekerabatan, Kakatua, Sekuen DNA, ?--fibrinogen
