Abstract

The study of lake fishes community in North Sulawesi and Gorontalo provinces was done during July and August 2001. The lakes of study were Tondano (St.1), Moat (St.2), Tondok (St.3) and Limboto (St.4) under observation methods to determine the  fishes diversity, abundance, local distribution, status and economy values. There were  17 different species from 12 families screened during this study, the Cyprinidae was the dominant one  and consist of three  species. Overall  the variation of  fishes consist of eight  introducable species and nine native species. The most abundance species was Ophieleotris aporos  and the most wide distributed was Cyprinus carpio, mostly species have  economic values. Comparing to three other lakes, the Limboto has the  most various species of  fishes.

Abstract

An Ethnobotanical study was carried out on a group of Talang Mamak tribe of the Bukit Tigapuluh National Park, Jambi. The inter-relationship and the dependency of the tribe with the forest plant resources were reflected by their daily lives by gathering medicine and hunting. The tribe lives surroundings HPH of the Dalek Esa Raya Co. Ltd. A number of 92 plant species were used as their food. About 70% of the species recorded were gathered from the forests, and the rest (30%) were as cultivated plant. Various botanical aspects of each species with its usage and utilization methods were discussed.

Abstract

Jika kita ingin mengetahui bagaimana hubungan kekerabatan antara manusia dengan  simpanse, maka buku karangan Jonathan Marks berjudul 'What it means to be 98% Chimpanzee: Apes, People, and Their Genes" ini cukup membantu. Setelah Allan Wilson (1985) mengemukakan bahwa 98,5% material genetik simpanse sama dengan material genetik manusia, banyak orang bertanya-tanya mengapa perbedaan yang hanya 1,5% tersebut, membuat manusia dan simpanse secara fisik jauh berbeda dan terpisah menjadi spesies yang berbeda selama jutaan tahun.

Abstract

Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is the most common human enzymopathy, nearly 400 different biochemical variants of the enzyme have been described worldwide.  The heterogeneity of these abnormal hemoglobins are very extensive in some populations such as the results of malarial natural selection and the use as genetic markers for certain populations.  As in  others malarious areas in Southesat Asia, the presence of G-6-PD deficiency in most Indonesians might be prevalent. Nevertheless the frequencies and epidemiological distribution of these hereditary blood diseases among Indonesians has not been well known yet.  This study  have screened  2 059 unrelated, apparently healthy adult blood samples from 17 different populations. The present investigation had  shown that the G-6-PD deficiency was commonly found in lesser Sunda populations sampled, hold beyond Bali to the east in significant frequencies range from 5% to 13.5%.

Abstract

The present  study aims to describe vegetation composition and structure of fragmented areas in Timor Tengah Utara. The study was carried out in three locations : the small forest of Soeb Mountain (L1), the medium forest of Ainiut-Loeram (L2), and the large  forest of Lapeom-Maubesi Mountain (L3). The data were collected using the quadrates method. Each transect is 0,52 ha and thirteen plots (20x20 m) was established. The results show that the number of trees species in the large forest is the highest followed by the medium and the small forests (L3>L2>L1); The tree density in the large forest is the highest, followed by the small and the medium forests (L3>L1>L2). However the highest tree basal area was recorded in the small forest, followed by the large and the medium forests (L1>L3>L2). The species of the highest importance value (IV) at three locations are Pterocarpus indicus Willd., Gossampinus malabarica (DC.) Merr., and Schleichera oleosa (Lour.) Oken.

Abstract

Polyculture cultivation improvement of Aloe vera Linn (A. vera Linn) and Vigna unguiculata (V. unguiculata) has been done using Rhizobium strains inoculation onto V. unguiculata seeds to increase their growth and production. The study was done in Ciomas district, Bogor, using rice paddy field with a total of 24th plots of 1 x 2,5m2 width. A. vera Linn was planted until  two months old using an interval of  60 x 60 cm2. The Rhizobium used were strains number 171, 172, 173, and their combination of those three, which was planted using an interval of  20 x 35 cm2. The negative controls were uninoculated, without N (K1) and the positive controls were uninoculated, with urea fertilizer equal to 100 kg/ha (K2). The experiment design was using Randomized Complete Block Design (RCBD) with four replications.  The parameters used were leaves numbers, dry weight of plants, roots, root nodules, and pods production of V. unguiculata and leaves number, leaves length and width of A. vera.  Results showed that isolate number of 172 (isolate of Glycine max Linn.) had given the best results on the production of  V. unguiculata in the polyculture system with A. vera.

Abstract

We present a strategy to preserve the biodiversity of Sulawesi and nearby islands chains. Sulawesi is the primary landmass in the biogeographic zone known as Wallacea, and is listed as one of the world’s top 25 hotspots at threat for major loss of biodiversity. Sulawesi is hypothesized to be subdivided into regions of endemism. We argue that the best strategy for preserving the totality of Sulawesi biodiversity, given that the vast bulk of that biodiversity remains virtually unstudied or even unknown, is to use biogeographic data to make a comprehensive map of regions of endemism in Sulawesi and to protect primary habitat in each region. We present a hypothesis that we call the “hybrid biogeographic hypothesis” that synthesizes two previous biogeografic hypotheses, one from empirical biological data and one from geologic data. We present a map of tarsier acoustic group distributions that offers heuristic evidence that the former hypothesis is more comprehensive than either of the latter two. We note that some of these regions have multiple conservation areas, while several others have none at all and can be thought of as “hotspots within the hotspot”. Evidence indicates that an endemic taxon of tarsier inhabits nearly every known endemic region of Sulawesi and surrounding island chains, although most of these taxa are undescribed. We propose to use tarsiers as flagship species to justify new conservation areas that will preserve primary habitat in those regions that currently lack them. Tarsiers are superior to other potential flagship species because they have the requisite charisma and are distributed throughout Sulawesi in a broad variety of habitats, but they do not eat agricultural products or have other characteristics that might engender local resentment to their conservation. This plan requires naming several new taxa of tarsiers, each of which requires reference material. Existing museum populations are inadequate for these needs and new museum specimens are required. We argue that the most beneficial way for this program to proceed is to trap wild tarsiers and house them in captivity until they expire naturally, at which time they will enter the collections of the Museum Zoologicum Bogoriense. While in captivity these tarsiers will provide enormous opportunities for research, training, education, and conservation. We will encounter local resistance to conserving tarsier populations because of false perceptions among inhabitants that tarsiers eat agricultural products, and this false belief must be corrected through community education. The critical condition of habitat destruction in Sulawesi warrants immediate action.

Abstract

Enterococcus faecalis ID 6017 can utilize glycerol as the source of carbon and energy for its growth. The present of glycerol in the medium containing Reactive Red-2 not only influenced its growth but also its ability to decolorize Reactive Red-2. The aim of this study was to investigate the growth of  Enterococcus faecalis (E. faecalis) and its ability to decolorize Reactive Red-2. The microbe was grown in batch system with three different growth medium, i.e. medium which contained (i) 1.643 g/l glycerol and 0.08 g/l reactive red-2, (ii) 1.643 g/l glycerol, and (iii) 0.08 g/l Reactive Red 2. The result of this study showed that the growth of  E. faecalis and its ability to decolorize Reactive Red-2 on medium contained glycerol was better than without glycerol. E. faecalis could not growth and decolorized Reactive Red-2 on medium without glycerol.

Abstract

Ular dianggap berkerabat dekat dengan kadal berdasarkan anatomi perbandingan yang memperlihatkan kemiripan struktur di antara mereka.  Beberapa ahli zoologi berasumsi bahwa moyang ular merupakan hewan sebangsa kadal yang dahulunya hidup di liang. Pola hidup di liang dengan menggali lubang di dalam tanah, membuat mereka tidak begitu memanfaatkan kedua pasang tungkainya sehingga lama-kelamaan mengalami penyusutan dan akhirnya berdegenerasi. Pada beberapa kelompok ular primitif, yaitu ular-ular yang keberadaannya di bumi lebih awal dalam perhitungan skala waktu geologi, masih dijumpai adanya sisa tungkai yang berbentuk taji di dekat kloaka, seperti pada Familia Boidae, yaitu:  ular Pyton  dan ular Boa, sedangkan gelang panggul masih terdapat pada Familia Typhlopidae (Anonim, 1988; Gibbons 1988).
