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).

Abstract

Contamination of mined soil and water affects not only to agriculture system but alsofood chains and epidemiological problems. As soil metal can not be biodegraded,remediation of soil heavy metal risks has been a difficult and expensive goal. Presentlythere are several different strategies available for the clean up and restoration ofcontaminated soils. One approach to minimize risks from some toxic pollutants isphytoextraction using hyperaccumulator plants, known as phytoremediation. In thisresearch Centrosema pubescens was studied to examine its potency ashyperaccumulator against cyanide. Although cyanide is not categorized as heavymetal, its presence is considered as one of important toxic pollutants in theenvironments. Detoxification of cyanide (CN) contaminated soils and waters withplants seems to be a feasible option. Centrosema pubescens which proven tolerant anddominant in the CN contaminated environment was used in this research. The plantswere grown in tailing waste media added by 0, 10, 20 and 30 ppm CN. Different pHlevels were applied, i.e.+ 6 and +5. The results showed that the plants were capable ofgrowing under high level of CN. The results indicated that Centrosema pubescens canbe considered as high tolerance and potentially effective in accumulating CN, i.e up to3.564 ppm in roots and up to 3.564 ppm in shoot with concentration ratio (shoot/root)up to 1.13. The plants also indicated high tolerance by producing high biomass underhigh level of CN, i.e up to 36.517 g (under 20 ppm CN).

Abstract

Penelitian tentang penyerbukan dan sistem reproduksi Ranunculus japonicus telah dilakukan di kebun botani Universitas Osaka City, Katano, Osaka, Japan. Hasil penelitian menunjukkan bahwa putik R. japonicus lebih dahulu masak daripada benang sarinya (protogyny). Pada tumbuhan ini terjadi ketidakcocokan silang sendiri (self-incompatible). Tumbuhan ini tidak mengalami penyerbukan sendiri (selfing) dan juga tidak membentuk biji tanpa pembuahan (agamosper my), tetapi melakukan penyerbukan silang (out-crossing) dan membutuhkan perantara (pollinator) untuk pembentukan bijinya.

Abstract

Medusa Phyllorhiza punctata mampu menghasilkan lendir yang dapat diserap olehmolekul organik serta berperan sebagai agregat atau sumber energi bagi pertumbuhandan perkembangan bakteri. Penelitian ini telah dilaksanakan dengan tujuan untukmengetahui pola produksi karbon organik terlarut (KOT) oleh medusa P.punctata danuntuk mendeterminasi hubungan antara produksi KOT dengan produksi dan konsumsioksigen dalam proses fotosintesis. Hasil penelitian menunjukkan bahwa medusa yangberukuran kecil (berat basah < 7 gram) menghasilkan oksigen lebih banyak dari jumlahyang dibutuhkan. Sedangkan medusa yang berukuran lebih besar mengkonsumsi oksigenlebih banyak dari jumlah yang dihasilkan. Secara individual, medusa dengan beratantara 4 - 6,8 gram dapat memproduksi karbon organik terlarut sebesar 27,44 mgkarbon per hari dan medusa yang berukuran besar dengan berat 27 - 45 gram dapatmenghasilkan KOT sekitar 308,7 mg karbon per hari.

Abstract

Agricultural practice is suspected to influence the availability of spiders in cashew plantation. The aim of this research was to study the diversity of spider in two different agricultural practices: monoculture and polyculture. The research was conducted in cashew plantations in Desa Kayangan (monoculture) and Desa Salut (polyculture), Lombok Utara. Two trapping techniques were used to sample the spiders: sweep net and pitfall trap. In each study area, 10 sampling sites were selected along line transect that was 5000 meters long. The study found 36 species of spiders from 12 families. The diversity and richness of spiders were higher in the polyculture cashew plantation than that in monoculture. Habitat structure was more complex in the polyculture cashew plantation; hence many species of spiders were able to coexist there.

Abstract

Sistem perkawinan pada burung (aves) sebagian besar (80-90%) adalah monogami. Namun temuan dari kajian-kajian terbaru dengan pendekatan molekuler menunjukan kalau jenis-jenis burung yang secara sosial monogami, ternyata berpoligami secara genetis (Birkhead dan Moller, 1992). Sebagai contoh, burung gereja (House sparrow Passer domesticus) melakukan extra-pair paternity (EPP). Artinya induk (jantan) mengasuh anak pasangannya yang ternyata bukan anak genetisnya.

Abstract

In the early stage of secondary succession process in 1 year old fost fire Kalampangan feat swamp area it was conducted a study on herbaceous plant species composition. The research found 6 fern species and 1 grass species out of 23 species representing 20 families. The coverage area of herbaceous vegetation was 13.12% or 1.312 m2 per hectare, which indicated relatively low percentage. In terms of relative dominance and frequency, herbaceous plant species in the area study was highly dominated by a terrestrial fern Stenochlaena palustris. Some tree species known as secondary and primary forest constituents such as Macaranga caladifolia (Euphorbiaceae), Dyera lowii (Apocynaceae), Combretocarpus rotundatus (Combretaceae), Cratoxylon arboresncens (Clusiaceae), Garcinia sp. (Clusiaceae) and Ploinarium alterifolium (Theacee) were found at their early growth stage on the forest floor but still in lower abundance compared to other recorded species from the study.

Abstract

The research was aimed to figure out the structure and composition of mangrove species in the delta of Siganoi River, Inanwatan District, South Sorong Regency, Papua. Belt transect was used and the data was analyzed using formula according to Clintron and Novelly. Research showed that ten species (seven genus) from five families were found in this area. At tree and sapling stages, Sonneratia alba performed the highest density with 324,1 trees/ha and 765,5 sapling/ha respectively, while at seedling stage Aegiceras corniculatumc with 69 seedling/ha. The highest frequency was found on trees and sapling of Sonneratia alba 0,966 and 0,431 respectevely. At the seedling stage, the highest frequency was found on species Aegiceras corniculatum (3970).

Abstract

The emergence of drug resistant and multidrug-resistant microbes as well as the lack of any current chemotherapy augmented the necessity to search for new and better anti-infective drug.. This study was aim to screen potential antiinfective extracts of sponges collected from Bunaken, Manado and to report on their antibacterial and antifungal properties. Testing for antiinfective agents was conducted using dilution method. Nutrient Agar was used as the testing media and nutrient broth for the inoculation of microorganisms. Staphylococcus aureus, Escherichia coli and Salmonella typhi were used as the testing bacteria and Candida albicans as the testing fungi. Chloramphenicol was used as positive control for anti bacterial activity and Ketokonazol for antifungi. The two acetone extracts tested (MD-01aceton and MD-02aceton), all of them showed inhibition activities. Following partition with chloroform and methanol, all chloroform extracts inhibited the growth of both bacteria and fungi. These extracts then are considered to be potential candidates for further isolation and characterization as antiinfective agents.
