Judul: Function Of Some Ecosystem Components At Natural Forest And Cacao Agroindustry Sustem At The Margin Of Lore Lindu National Park, Central Sulawesi
Abstrak: Cacao agroforestry is a traditional form of agriculture practiced by the people of Central Sulawesi. These agroforestry systems vary from a simple system, following selective cutting of forest trees, to a more sophisticated planting design. The aims of this research were (1) to determine litterfall dynamics, leaf-litter decomposition, and fine root biomass, (2) to determine active fraction on soil macro-organic matter (SOM) in natural forest and cacao agroforestry systems, and (3) to assess nitrogen resorption and nitrogen use efficiency (N NUE) and implication for cacao establishment. The field studies were conducted in three types of cacao agroforestry systems at the northeastern margin of Lore Lindu National Park (LLNP). Field study sites covering in natural forest (NF) and in three cacao agroforestry systems that is cacao was planted under remaining forest cover (CF1), under planted trees (CF2), and between shade trees Gliricidia sepium (CP). The parameters are nitrogen soil content, fine root biomass, soil macro-organic matter by size and density fractionation, soil surface organic layer by quadrant, litterfall production by litter trap, and rate of decomposition by litter bag, nitrogen use efficiency in cacao plant and ecosystem scale, and nitrogen resorption.

Judul: Interactions between Natural Enemies Herbivores and Cacao in Palolo Valley, Central Sulawesi
Abstrak: This study on interactions between natural enemies, herbivores and cacao was conducted in Palolo valley at the eatern margin of the Lore Lindu National Park, Central Sulawesi between April 2001 and June 2003. The research focused on four main aspects : (1) tritrophic interactions between ants, Homoptera and cacao; (2) effects of habitat isolation on ants communities in cacao plantation; (3) effects of ant communities on cacao pests and disease; (4) the potential of artificial nesting sites for increasing population density of the black cacao ant. The main objectives of the research were to study: (a) the importance of cacao agroforestry for maintaining biodiversity, and (b) the interactions between natural enemies such as ants and cacao pests and disease.

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.
