Abstract

Teluk Lake of Jambi have a potency to be developed for fishery. This research aims toinvestigate the diversity of lais fish (Kryptopterus spp.) based on their morphological characters.The research was carried out from Novemberto December 2008. The collected fish samples wereidentified their morphological characters in the Biological UP MIPA Laboratory at the University ofJambi.

Abstract

Dragonflies (Odonata) belong to the phylum Arthropoda class Insecta. Dragonflies are spread in various types of habitats, one of which is in the water area, namely Lake. Danau Tangkas is one of the natural tourism areas in Jambi province. Danau Tangkas is a conducive habitat for dragonfly breeding because the habitat conditions around Danau Tangkas are still beautiful with preserved vegetation. However, the Danau Tangkas area is a tourist area, so it has the potential to experience changes that can have an impact on the dragonfly dominance index. The study aims to analyze the dominance of dragonflies found in the Danau Tangkas natural tourism area. The type of research is exploratory descriptive research. Sampling was done using purposive sampling method. Sampling was carried out at 3 location points that have different characteristics. Made 3 stations with a length of 100 m each to the side and 100 m to the front so as to form a square line. Sample collection is done by hand collecting and using insect nets. Data analysis techniques using Simpson's dominance index calculation. The results of research that has been carried out in the Danau Tangkas  natural tourism area, obtained as many as 447 individuals, 9 species belonging to 3 families. So it is known that the dragonfly dominance index in the Tangkas Lake natural tourism area is low with a value of 0.4.

Abstract

We undertook a research about the role of cinnamon agroforest in conserving bird inKerinci Seblat National Park. To observe the bird we used method of Indice Poctuale De'Abundance,whereas for the bird identification we employed some methods developed by Mckinnon ( 2001) andKing and Dickison (1993). As a control we also carried out the similar observation in the closed byprimary and secondary forest. The result shows that the bird diversity in cinnamon agroforest is notsignificant compare to that in primary and secondary forest (p>0.05). The index of bird diversity ( H') incinnamon agroforest and secondary forest is in medium class (3.3 and 3.49) while in the primary forestthe index is high (3.50).

Pengamatan lutung dilakukan dengan metode scanning mulailutung aktif pada pagi hari sampai sore hari. pengamatan dilakukan selama sepuluh hari berturut-turut. Hasilpenelitian menunjukkan rata-rata persentase aktivitas lutung dalam satu hari untuk makan 57,7%, pindahtempat 10,2%, istirahat 19,4% dan aktivitas lainnya 12,7%. Jauh pergerakan harian lutung di hutan sekitarkampus pinang masak, universitas jambi yaitu rata-rata day range (DR) 669,8 m, night position shift (NPS)241,9 m dan maximum radius (MR) 336,7 m.
