Judul: Keanekaragaman Lumut di Jalur Pendakian Cemoro Sewu Gunung Lawu, Jawa Timur.
Abstrak: Tropical forests have higher diversity of bryophytes species than other regions in the world. Diversity and abundance of bryophytes depend on the altitude. This study aims to inventory the diversity of bryophytes of Mount Lawu and their distribution based on the altitude and type of substrate. Sampling was carried out along a hiking trail of Cemoro Sewu. Total of 85 species (34 families, 56 genera), consist of 55 species of mosses (17 families, 35 genera), 28 species of leafy liverworts (15 families, 19 genera), one thalloid liverworts, and one hornworts species were found in the study. Dicranaceae (19 species, seven genera) and Bryaceae (eight species, four genera) have higher much of species. Those mosses were found mostly terrestrial growing on rock substrate. Bryophytes distribution evenly on upper mountain zones as well as at sub-alpine zone. The diversity of leafy liverworts more higher in the mountain zone (2000-3000 masl) than in sub-alpine zone (3000-3265 masl).

Judul: Diversitas Lumut Epifit di Tiga Perkebunan Teh Jawa Barat
Abstrak: Study on the epiphytic bryophytes was conducted at three tea plantations located at different elevation in West Java: Gunung Mas (600 m) Bogor, Nirmala (1150 m) Sukabumi, Rancabali (1628 m) Bandung. Three plots were established within each tea plantation, three transects of 30 m were lined in each plot. Samples were collected from the trunk and primary branches of five tea trees in each line transect. The aims of this study were to record the epiphytic bryophytes species of the plantations and to compare diversity of the bryophytes community among the plantations. Ninety species of epiphytic bryophytes were recorded. Checklist of those species were provided in this paper. The bryophytes species richness of the plantations increased with increasing of the elevation. Twenty seven species were found at Gunung Mas, 40 species at Nirmala, and 74 species at Rancabali. The plantations were dominated by different species. The dominant species were Sematophyllum tristiculum (mosses) at Gunung Mas, Lejeunea anisophylla (liverworts) at Nirmala, and Acanthocoleus javanicus (liverworts) at Rancabali. The species composition of the bryophytes communities of Gunung Mas was more similar to that of Nirmala compared to that of Rancabali.

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.
