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.

Abstrak: Indonesia has a high biodiversity of plants including bryophytes. Studies on the bryophyte diversity of Indonesia has not comprehensively done. Bogor Botanical Garden is one of the ex-situ conservation providing suitable habitat for bryophytes. Studies on the hepaticae of Bogor Botanical Garden are urgently needed. In this studies, bryophyte sampling were done in three blocks where the collection of Meliaceae, Myrtaceae and Lauraceae. Sampling was done based on the difference of growth position of tree (0-100 cm and 100-200 cm above ground) and at the difference of compass point (west, east, south, and north). Specimens checklist of bryophytes in the Herbarium Bogoriense (BO) as well as the herbarium specimens were studied. There are 92 species leafy liverworts are known at the sampling areas in Bogor Botanical Garden and herbarium specimens record at BO. There are 33 species leafy liverworts of epiphyte hepaticae were collected. In this studies, 7 species are recorded as the same as the BO specimens, the rest of 26 species are different with BO specimens. Lejeuneaceae has the highest diversity number, and highest percentage of coverage. Myrtaceae block has the highest diversity number and species abundance of hepaticae, that is 17 species and 52.9% of the total coverage. All of the blocks, position of tree 0-100 cm has the highest species abundance and frequency. A determination key to the species epiphytic hepaticae of Bogor Botanical Garden is presented.

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.
