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: Keanekaragaman Lumut Epifit pada Gymnospermae di Kebun Raya Bogor
Abstrak: Researchs on diversity of epiphytic bryophytes are more common observed on Angiospermae than those on Gymnospermae. Bogor Botanical Garden (BBG) is an ex-situ conservation in which the sample plants are collected around the world for conservation purpose. Trees in the Botanical Garden provide substrats for epiphytic bryophytes. The temperature and humidity in the Botanical Gardens were the optimum range for the bryophyte growth. The aim of this research was to observe diversity of epiphytic bryophytes on Gymnospermae in BBG. The bryophyte samples were collected from Gymnosperm trees in Blok I which is Cycadaceae familly and those in Blok II which are the familly of Pinaceae, Araucariaceae, Gnetaceae, dan Podocarpaceae. Only the trees have ≥ 20 cm (dbh) of trunk base were sampled. Bryophytes were collected from the trunk base at 0-200 cm above the ground, at four cardinal direction (north, south, west, and east). In total 18 species of epiphytic bryophytes were found, included 12 genera and 7 families. The family which had the highest number of species was Lejeuneaceae. The most common species on Gymnosperm trees in the Botanical Garden were Lejeunea tuberculosa and Octoblepharum albidum. Both of them were found at 6 trees of 13 total tree samples. The species were found more frequently at west (2,1%) and north (1,8%) part than east and south part of the host trees. They more frequently inhabit the trunk base on 0-100 cm than 100-200 cm. Key words: Bogor Botanical Garden, diversity, epiphyte bryophyte, Gymnospermae.

Abstrak: The aim of this study was to learn the role of diagnostic imaging to define the diagnose of the upper gastrointestinal tract disorder of the Schnauzer. The information from the owner (anamneses) stated that the dog has been vomiting for a year, sometimes containing blood. There might also be a possibility that it had eaten a corpus alineum. This study case covered physical examination, hematology and blood chemical analysis, radiography, ultrasonography, and endoscopy performed. Physical examination showed weight loss and anorexia. Hematology and blood chemical analysis showed an increase in lymphocyte, haemoglobin (Hb), haemotocrit (Hct), ureum, creatinine, alanin aminotransferase (ALT), and alkaline phosphatase (ALP). Abdominal radiograph showed no abnormality in the abdominal organs. Abdominal ultrasonography showed a hyperechoic mass on the stomach mucosal surface. The mass forms an acoustic shadowing at the ventral. The acoustic shadowing in the stomach may be caused by an accumulation of gas or foreign object such as bone. Endoscopy showed that there was inconsistency of stomach mucosa surface, foamy bile fluid in the stomach, ulcers, and erosion of the stomach mucosal surface. Based on the endoscopy performed, the animal was clearly diagnosed with chronic gastritis accompanied by stomach ulcer and erosion.
