Abstract

As chromosome of different species differs in the size, shape, and number, their caryotpes areexpected to provide a distinctive and characteristic feature of the organism. The caryotypes ofseven amphibian species : Limnonectes gruniens, L modestus, Rana (Hylarana) chalconota,Fajervarya cancrivora, Polypedates celebensis, Bufo celebensis and B biporcatus of South EastSulawesi-origin were investigated. The result showed that the number of diploid chromosomes inthe seven anuran varied between 22-26. The highest diploid chromosomes were observed in Rchalconota, F cancrivora (26), followed by L gruniens, L modestus (24) and the lowest were observed22 in P celebensis, B celebensis and B biporcatus (22). In general, all the the seven anuran sharesfour metacentric chromosomes pairs which is in pairs No 5, 6, 9, and 10 respectively. Howeverdifferences were observed in other chromosomes pairs numbers among the seven species.

Abstract

The objectives of the research was to described habitat charateristics and reproduction aspects of giant frog (Limnonectes cf. grunniens). Some physico-chemical parameters that characteristic for giant frog habitat i.e. air and water temperatur, relative humidity, dissolved oxygen, free CO2 and NH3 in water were measured. Moreover, the reproduction aspects being observed were gonad characteristics, egg size and form, and sperm density. The results indicated that the giant frog habitat was river stream with physical characteristics as following air temperature : 27o–28oC, water temperature : 24o-26 oC, relative humidity : 83%–87%, water turbidity : 1,2–11,6 nephelometric turbidity unit (NTU), and altitude : 20-40 m above sea level. Furthermore, the suitable water characteristics for the habitat were dissolved oxygen : 7.78.2 ppm, free CO2 concentration = 6.6–8.1 ppm, and free NH3 concentration : 0.5–0.6 ppm. The adult giant frog female generally carried 1461.82 eggs in average per individu with diameter ranging from 1.70–3.10 mm. On the other hand, the sperm density of adult male giant frog was found to be 1,614,898 per mm3 with motility rate of 81.23%.
