Abstract

ABSTRACTStudy on The Relationship Between Phytoplankton and Current Velocities due to Operationof Jatiluhur Reservoir. High abundance of phytoplankton may create oxygen depletionwithin water column, in which may also lead as a threat to the fisheries activities of floatingcage in the Jatiluhur reservoir. In addition, phytoplankton may also clog the filter within watertreatment plant that is currently using the water from Jatiluhur reservoir. The research objectivewas investigate effects of changing water current velocity to the abundance of phytoplanktonin the Jatiluhur reservoir. Phytoplankton, measured as chlorophyll-a, were sampled at 10 differentsampling points of 0, 4, 8 and 10 m depth. While current water velocities were calculated usingtwo-dimensional multilayer equation. The equation will calculate x and y axis current velocitieswithin different depth of the reservoir. Result shows that in the area in which the currentvelocities higher than 15 cm/s less phytoplankton would be found. These velocities found ifthe operation of water discharge from reservoir was more than 70 m3/s. The research suggeststhat discharging operation from reservoir can be used as an indicator for the early warningsystem for the fisheries activities in the reservoir.Keywords: Jatiluhur reservoir, current velocity, phytoplankton abundance, reservoir operation,two-dimensional multilayer equation

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

Abstract

ABSTRACTProfile of Small mammals from Gunung Slamet, Central Jawa. Research of small mammals atGunung Slamet, Central Jawa was conducted. Three types of habitats as representation ofprimary forest, secondary forest and plantation were examined at Kalipagu, Kaliwadas andBambangan in order to record its small mammals biodiversity. Combination of trapping anddirect observation recorded 31 species of small mammals from the areas observed. Shannon-Wiener index was the highest in secondary forest (3.8) compared to primary forest (3.6) andplantation (3.4). The results indicated that most small mammals of Gunung Slamet use secondaryforest for their home range. However data on microchiropterans that were more frequentlyrecorded in plantations indicated that agricultural plants were their primary foraging areas. Onthe other hand, most of small mammals species were rely on both secondary forest and primaryforest as an important food resources. The dendogram resulting from cluster analysis wasconcordant with this view. Primary forest and secondary forest clustered closely together,while plantation was recognized as a distinct group.Key words: Small mammals, Gunung Slamet, biodiversity, habitat.

Abstract

ABSTRACTThe Exploitation Rate of Endemic Bonti-bonti (Paratherina striata) in Towuti Lake. Bonti-bonti(Paratherina striata) is an endemic fish species as vulnerable species to extinction. This fish livein Towuti and Mahalona Lake the tectonic-oligotrophic lakes that are located in Malili Complex,South Sulawesi. This lake is used for various purposes i.e. hydroelectric power plant, capturefishery, navigation, ecotourism and source of water for domestic uses. This lake also supports lifeof endemic fish species that should be protected from decreasing population due to intensiveexploitation. The objective of this research was to study the exploitation rate of Bonti-bonti asconservation efforts. The study was done in Towuti Lake from May 2006 to April 2007 usingdescriptive method. Utilization rate of Bonti-bonti stocks in Towuti Lake indicated an overfishingcondition of male and female population. Increasing effort (units/month) of dipnet tends to reducefishing gear productivity.Key words: exploitation rate, Bonti-bonti, endemic fish and Towuti Lake

ABSTRACTSexual Dimorphism, Reproduction and Prey of Long Tailed Lizard Takydromus sexlineatusDaudin, 1802 (Lacertilia :Lacertidae). The morphology and reproductive biology of Takydromussexlineatus were studied in Bogor. Males are larger than females. There is sexual dimorphism onhead size and tail length (larger and longer tail on males) of body size among sexually matureadults, apparently as a consequence of sexual selection. The diet of T. sexlineatus consists ofvariety of insects and their larvae, arachnids, decapods and snails. Most of the diet are insect(more than 70 % for adults and juveniles). There are higher prey competitions at adult skinksbetween males and females, adult females and juveniles, but not between adult males andjuveniles. The length of adult males and females are 44.6 - 58.1 mm and 49.6 - 62.3 mm respectively,lay eggs throughout the year with 2 -3 clutches, per clutch consists of 1 - 3 eggs.Key words: Lizard, Takydromus, Ecology, Sexual Dimorphism, Prey, Reproduction, Bogor, Indonesia
