The tropical zone of Mount Ungaran is a tropical forest which are rich in diversity of flora. One of them is Bryophytes. Most of the Bryophytes of tropical forest are epiphytes. The largest group of Bryophytes is mosses (Bryophyta). However, research about epiphytic mosses in this area are sparse, so it is only a few information given about epiphytic mosses in this area. The aim of this research was to identify epiphytic mosses in tropical zone of Mount Ungaran altitudes 750, 980, and 1.100 meters above sea level, and also to determine the frequency attendance of species in this study site. This research was conducted in April through November 2012. Specimens was carried out at Laboratory of Ecology and Biosistematics, Department Biology, Faculty of Science and Mathematics, Diponegoro University, Semarang, Indonesia. The results shown there are 35 species mosses. Diversity of epiphytic moses most commonly found at altitude 1.100 meters above sea level, as many as 17 species, while at altitudes 750 and 980 meters above sea level was found 15 species. Family Hypnaceae is the family with highest number of species (6 species) and has highest total amount of frequency attendance by 16,13%. Hypnum plumaeforme and Luisierella barbula were the species which had wide distribution. Both of them were found at all three altitudes. Species with the highest total amount of frequency attendance is Hylocomium splendens from family Hylocomiaceae with total amount by 9,68%. Key words : epiphytic mosses, Mount Ungaran, tropical zone

The palms are a very diverse group, which mostly distributed in tropical forest, they are large ecological amplitude that extends from temperate environments to deserts and from sea level to high altitudes. The anatomy of the fossil axis shows the anomalous types of secondary growth and critical observations suggest that it belongs to the tribe Dracaeneae of the family Dracaena as well as to some extent Cordyline. The characterized by fossil palm wood is highly indicated the much high rainfall and a moist climates in contrast to the desert and scrub forest. The detailed anatomical study revealed with affinities of the extant genus of Cordyline taxa comes under the family Arecaceae. Its geographical range is also distinct, limited by tropical climatic conditions.

ABSTRACT: Wrinkled-faced bat, Centurio senex, belong to the family Phyllostomidae, are small to medium size, color variable but usually yellowish brown, each presenting a shoulder patch of white hair in the wing membrane areas have translucent skin, usually perches under the leaves on trees to the weather. Centurio senex is distributed throughout in the Neotropics, in evergreen forests, rain forests, and in lowland deciduous. On December 8, 2002 was a Centurio senex specimen was found in the municipality of Nezahualcoyotl, Col. Bosques de Aragón, Mexico State. Was found dead, raising a eucalyptus tree (Eucalyptus sp.) We report here the presence of C. senex in the State of Mexico, this record is completely atypical, since these fruit bats live in tropical forest, and was probably brought to the area in a fruit cargo from a tropical region. KEY WORDS: Centurio senex, distribution, Estado de México, record.PALABRAS CLAVE: Centurio senex, distribución, Estado de México, registro.

The family Zoridae (F.O. Pickard-Cambridge, 1893) is currently represented by 14 genera and 79 species distributed worldwide (Platnick, 2012), of which only the genera Xenoctenus Mello-Leitão, 1938 and Odo Keyserling, 1887 are present in Americas. Xenoctenus is represented by four species, all endemic to Argentina, while Odo has, so far, a total of 27 species distributed in Central America, South America, West Indies and Australia (Platnick, 2012). The type species of Odo is O. lenis Keyserling, 1887, a specimen female described from Nicaragua. The genus Odo has never been revised and given its wide distribution and number of species, it is probably a polyphyletic genus and a complete revision is required. Also, no new material of O. lenis or O. patricius has been described since 1900.

Six genera of the order Pleosporales are revised taxonomically. Although five genera have unusual applanate ascospores, they are members of three different families. Clathrospora (10 species, 2 new), Comoclathris (21 species, 7 new), and Macrospora (3 species) are placed in a new family Diademaceae in which the ascoma opening is a characteristic flat circular lid. Diademosa, a new genus with one species with terete ascospores is placed in Diademaceae. Graphyllium (3 species) is placed in the family Hysteriaceae characterized by hysterothecia with a slit-like opening. Platysporoides n.gen. (11 species, 1 new) is maintained in the Pleosporaceae because of the terete pored beak of the ascomata. Key words: Pleosporales, applanate ascospores, Clathrospora, Comoclathris, Macrospora, Diademosa, Graphyllium, Platysporoides.

Dry tropical forest communities are among the world's most threatened systems and urgent measures are required to protect and restore them in degraded landscapes. For planning conservation strategies, there is a need to determine the few essential measurable properties, such as number of species and basal area, that best describe the dry forest vegetation and its environment, and to document quantitative relationships among them. This paper examines the relationships between forest basal area and diversity components (number of species and evenness) for a disturbed dry tropical forest of northern India. Data were collected from five sites located in the Vindhyan dry tropical forest of India, selected on the basis of satellite images and field observations to represent the entire range of conditions in terms of canopy cover and disturbance regimes. These sites represented different communities in terms of species composition. The forest was poorer in species richness, and lower in stem density and basal area than wet forests of the tropics. Across sites (communities), the diversity components and tree density were positively related with total tree basal area. Considering basal area as a surrogate of biomass and net production, diversity is found to be positively associated with productivity. A positive relationship between basal area, tree density and species diversity may be an important characteristic of the dry forest, where recurring disturbance does not permit concentration of biomass or stems in only a few strong competitors. However, the relationships of basal area with density, alpha diversity and evenness remain statistically significant only when data from all sites, including the extremely disturbed one, are used in the analysis. In some sites there was a greater coefficient of variation (CV) of basal area than in others, attributed to patchy distribution of stems and resultant blanks. Therefore, to enhance the tree diversity of these forests, the variability in tree basal area must be reduced by regulating local disturbances. Conservation activities, particularly fuelwood plantations near human settlements, deferred grazing and canopy enrichment through multi-species plantations of nursery-raised or wild-collected seedlings of desirable species within the forest patches of low basal area, will be needed to attain restoration goals, but reforestation programmes will have to be made attractive to the forest-dwelling communities.

Aim.The aim of the work described herein was to study the dynamics of allantoin accumulation in the underground phytomass ofEchium vulgareL.,Symphytum caucasicumM. Bieb. andS. asperumLepech. as well as to clarify the role of allantoin in plant adaptation to stress factors.Methods.We studied the roots of plants growing in the foothill (Nalchik, 490–512 m above sea level) and the mountain zones of the Kabardino-Balkarian Republic (Terskol village, 2530 m above sea level; Verkhnyaya Balkaria village, 2680 m above sea level). The roots were collected at the stages of rosetting, flowering, fruiting and at the end of the growing season. Aqueous-alcoholic extracts of shredded roots were analyzed by high-performance liquid chromatography.Results.The highest content of allantoin in the roots ofEchium vulgare,Symphytum caucasicum,S. asperumplants was noted at the end of the growing season, respectively 0.915; 0.342–0.658; 2,842–3,426%. Under conditions of low temperatures and increased solar radiation, the content of allantoin in the roots increases 1.2–1.9 times as compared with the plants of the foothill zone.Conclusion.Allantoin plays an important role in the process of adapting species of the family Boraginaceae to oxidative stress caused by hypothermia and increased solar radiation.
