Abstract

Nepenthes spp. (Nepenthaceae) is one of the most popular ornamental plants in Southeast Asia. There are 97 species of Nepenthes to which 64 are found in Indonesia with the center of its diversity located in Borneo. N. x hookeriana was hypothesised to be a natural hybrid between N. ampullaria and N. rafflesiana on the basis of morphological characters. Several variants of each species were also known. This present study aimed to detect the occurrence of hybrid within N. x hookeriana ‘spotted’ and ‘green’ variant using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR). Five RAPD primers and three ISSR primers were used to amplify total DNA genome and produced 83 polymorphic bands ranging in size from 300-1700 bp. Clustering analysis was performed based on RAPD and ISSR profiles using the UPGMA method. The genetic similarity of the combined markers range between 0.30-0.75 indicating a narrow range of genetic similarity among the accessions. Results from cluster analyses suggested that N. x hookeriana was indeed a hybrid between N. ampullaria and N. Rafflesiana, however it was genetically more similar to N. raflessiana.

Abstract

Guna mengetahui struktur dan komposisi vegetasi hutan di Taman NasionalLore Lindu Sulawesi Tengah telah di laksanakan pada bulan Mei 2002. Studi dilakukan di 2 lokasi yakni desa Salua (0,5 ha pada 550-640 m dpl.),kabupaten Donggala, and desa Kaduwaa (0,5 ha pada 1100-1150 m dpl),kabupaten Poso. Penelitian dengan “Quadrate-methode” ini mengungkapkan bahwa vegetasi hutan di Salua memiliki jumlah pohon, spesies, jenis dan famili lebih besar daripada di Kaduwaa; namun demikian kepadatan di Salua lebih rendah daripada di Kaduwaa. Vegetasi tersebut di Salua didominasi oleh Palaquium obtusifolium, Toona sureni, Pterospermum celebicum, dan Canarium hirsutum; sedangkan di Kaduwaa oleh Santiria laevigata, Ficus sp., Cryptocarya tomentosa, Semecarpus longifolia, dan Syzygium operculata. Selanjutnya penelitian ini mengungkapkan bahwa komposisi vegetasi pohon di Salua dan Kaduwaa adalah berbeda, tetapi memiliki struktur yang relative sama. Dan akhirnya diungkapkan bahwa komunitas tumbuhan di dua lokasi penelitian adalah berbeda (Indeks kesamaan Sorensen 19).

Abstract

The degradation rate of forest in the recent 5 years increases rapidly,particulartly in Sulawesi. The biggest damaged comes from the human impact,which spreads to the conservation area. As a result, the areais decreased,whereas its function and its potency have not been explored. The ecologicalresearch has been conducted in Soloi forest, Suaka Margasatwa Buton Utara inMay 2003. The objectives of this work are to study the condition, which belongto. 75 general and 35 families with density of trees are 277 individual (stemdiameter > 10 cm ), and 1140 sampling ( 2-9,9 cm stem diameter ). The foresttype is low land primary forest, which dominated by Casearia rugulosa,Diospyros pilosanthere, Cleistanthus myriantus, Canarium hirsutum, andDrypetes longifolia. In the forest structure, trees with 10-20 cm stem diameter isin the first rankwith the total number 57,02%, then followed by the trees with 20-30 cm diameter (20,22%). In general, the forest condition in research site isgood, although a few areas are damaged due to illegal loging.

Abstract

Bawean Island is a remote and tiny island, located approximately 150 km north of Surabaya. In this island it is known to habituate an endemic deer called Bawean deer (Axis kuhlii Mull. Et. Schleg). The animal is protected both nationally and internationally. Understanding the forest as the habitat for this deer is an important step toward the management and the development of the whole habitat. This study was conducted on September 2001 in three locations, known to be the habitat for Bawean deer, that was the Kumalasa, Patarselamat and Pudakit Barat villages. The forest type at study sites was lowland secondary forest. There were 114 species from 90 genus and 56 families. Number of species and trees density at Audacity Barat villages are bigger than Patarselamat or Kumalasa villages. In all study sites, Syzygium lepidocarpa, Irvingia malayana, Garcinia dioica, and Microcos tomentosa are common species.Trees height in three location were under 25 m tall, and stem diameter class were highest among 10-20 cm. Species richness (Ss) ranged from 22,7 to 55,7%. The plant communities in Patarselamat and Pudakit Barat were relatively same, but different with Kumalasa village.

Abstract

Study of plant ecology in around of Wani Mountain, Buton Utara GamePreserve, South-East Sulawesi, was conducted in April 2004. Two plots each 0,5 ha (50x100m) on 300 and 400 m a.s.l were established.

Abstract

Ecological studies on the Nepenthes species at Barito Ulu, Central Kalimantan, Indonesia were conducted between August 2005 and September 2006. Surveys and two small plot inventories were used to determine the diversity and population of Nepenthes at the study site. We found eight Nepenthes species around the BaritoUlu study area: N. albomarginata, N. ampullaria, N. gracilis, N. hirsuta, N. rafflesiana, N. reinwardtiana, N. stenophylla, and N. hispida. Plot A was dominated by N. rafflesiana with one other species found; whilst in plot B we found five species but it was also dominated by N. rafflesiana. In plot A, the one year stem length growth rate of N. albomarginata was faster than N. rafflesiana (5.0 and 3.5 cm respectively). While in plot B, N. gracilis (21.7 cm) and N. reinwardtiana (13.1 cm) showed faster growth rates than N. albomarginata (5.2 cm), N. rafflesiana (7.0 cm) and N. stenophylla (8.5 cm). Generally, the habitat of Nepenthes in the study site is heath forest.
