Abstrak: Tropical montane forest ecosystem making up 21 percent of the total area of the world’s tropical forest. This ecosystem has high level of species diversity, constributes positively to the water catchment, and provides an essential habitat for many endemic and threatened plant and animal species. The objectives of this research were 1) to determine plant species diversity, 2) to study composition of vegetation community and tropical montane forest structures. This study was conducted at three primary forest sites were located in Lore Lindu National Park, Central Sulawesi. The first site was located in Watukilo at 900 m asl, the second site was in Torongkilo at 1 500 m asl, and the third site was in Torenali at 2 300 m asl around 1.5 km to peak of Mount Rorekatimbu. All sites are submontane forest, lower montane forest, and upper montane forest respectively. Plot-based plant inventory and identification were carried out in the period of July 2011 to July 2012. Plot size was 40 m x 60 m (0.24 ha) devided up into a 10 m x 10 m grid. All trees of diameter at breast height (dbh) ≥10 cm (at 1.3 m). Within each of the 10 m x 10 m, one 5 m x 5 m-sized subplot was surveyed (0.06 ha per plot) to study saplings (2 cm ≤ dbh < 10 cm), and one 2 m x 2 m-sized subplot (0.024 ha) to additionaly study understorey vegetation in each of the 5 m x 5 m subplot. We recorded a total 310 plant species belonging to 129 genera and 106 families in all forest types. Lower montane forest has the highest species richness (61 tree species, 51 sapling species, 57 seedling species, and 56 understorey plant species), followed by submontane forest and upper montane forest. Shannon diversity index showed that all forest types in this study has moderate to high in species diversity (2 < H' < 4), and has low similarity in species composition with the similarity <10% (Sørensen index). Among the species recorded, only one species that found in all three forest types, i.e. Lithocarpus celebicus (Fagaceae). In submontane forest, the most dominant tree species were Castanopsis buruana (Fagaceae), Gironniera subaequalis (Cannabaceae) and Santiria apiculata (Burseraceae), while the most dominant saplings were C. buruana, S. apiculata and Praravinia mindanaensis (Rubiaceae). For seedlings and understorey, the most dominant species were Antidesma riparium subsp. riparum (Phyllanthaceae) and Calamus sp.1 (Arecaceae), respectively. In lower montane forest, the most dominant tree species were Platea excelsa var. borneensis (Icacinaceae), Elaeocarpus sp.1 (Elaeocarpaceae) and Magnolia carsonii var. carsonii (Magnoliaceae), while the most dominant saplings were Lophopetalum beccarianum (Celastraceae), Ardisia forbesii (Primulaceae) and Cyathea contaminans (Cyatheaceae). For seedlings and understorey, the most dominant species were Calophyllum soualattri (Calophyllaceae) and Calamus sp.5, respectively. In upper montane forest, the most dominant tree species were Phyllocladus hypophylla (Podocarpaceae), Dacrycarpus steupii (Podocarpaceae) and Lithocarpus havilandii (Fagaceae), while the most dominant saplings were Trimenia papuana (Trimeniaceae), Tasmannia piperita (Winteraceae) and Myrsine minutifolia (Primulaceae). For seedlings and understorey, the most dominant species were Myrsine minutifolia (Primulaceae) and Sonerilla pumila (Melastomataceae), respectively.

Judul: Structure and composition of vegetation in six land use types in the lore lindu national park, Central Sulawesi, Indonesia
Abstrak: Sulawesi is the largest island in the Wallacea region, a unique region in the world. The island possesses many endemic plant and animal species, not occurring in other parts of the world. Nevertheless, the scientific knowledge of Sulawesi's flora both axonamically and ecologically is still limmited due to lack of botanical research and publications on this subject.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
