Thirteen species of Coccomyces are reported for Australia; a further species is recognised but not described because of insufficient material. Six of the species are described as new. Most of the Australian species are C. leptosporus-like in morphology, a characteristic of most Coccomyces spp. from tropical and Southern Hemisphere regions. One of the new species, C. cunninghamii, found on Nothofagus cunninghamii, is morphologically similar to Lophodermium medium, a species occurring on N. menziesiiin New Zealand. The seven previously described species also occur in New Zealand, and three of them are widespread in tropical Asia and tropical America. All species are described and illustrated, and a key to the Australian Coccomyces species is provided.

AbstractIn this paper, we argue that bird atlases, and the databases from which they are produced, are becoming increasingly valuable resources – but only in some parts of the world. There is a striking lack of atlases for almost all of the world's species-rich areas, most notably tropical America and tropical Asia. Yet even comparatively modest data sets (we take Uganda as an example) can be used to create an atlas. Further, their data can yield interesting information with clear value for conservation planning. For instance, we can see that Uganda's main savanna parks are quite well-placed in relation to raptor species richness, whilst other species of conservation concern are less well covered. In contrast, the fine-scale data-rich atlas projects in many American and European countries provide detailed information of great value. Taking examples from England, we show some of their uses in planning both for physical developments and for conservation. Repeating atlas projects after an interval of several years highlights changing distributions and, increasingly, changing levels of abundance. We believe that every encouragement should be given to new (and repeat) atlasing projects - but most especially in the tropics.

AbstractThe supposedly cosmopolitan species Nomophila noctuella (Denis and Schiffermüller) is shown to be one of a complex of 12 distinct species, some sympatric, some allopatric, and none ranging over more than three continents. N. noctuella itself has the widest range, extending through most of the Palaearctic and Ethiopian regions, including Madagascar, and into tropical Asia as far as India and Pulo Laut. It also occurs adventively in Hawaii. Two additional endemic species, N. africana n. sp. and N. brevispinalis n. sp., occur in Africa; the Australian species, N. australica n. sp., is endemic but occurs, probably adventively, on Christmas Island. The North American species, N. nearctica n. sp., is distinct from N. noctuella, but, like it, is a migrant and ranges south to northern tropical America. There are six endemic species in South America: N. colombiana n. sp., Colombia; N. heterospila (Meyrick), Andes, transferred from Macronomeutis, which falls as a synonym of Nomophila; N. helvolalis (Maassen), Andes; N. distinctalis n. sp., Peru, Bolivia, and Chile; N. indistinctalis (Walker), central and southern South America; and N. triticalis Berg, Argentina and Paraguay, to which N. squalidalis (Hampson) falls as a synonym. N. incognita Viette, known from a single female from Amsterdam Island, Indian Ocean, is a good species.

Disjunctions between tropical America and tropical Asia, commonly called amphi-Pacific tropical disjunctions, have frequently been discussed among flowering plants but have received very little attention in bryology. A screening of the literature revealed nine species and sixteen genera or infrageneric taxa of bryophytes with amphi-Pacific tropical (or subtropical) ranges. They include Austinia tenuinervis, Diphyscium chiapense, D. longiflorum, Elmerobryum, Fissidens sect. Sarawakia, Ganguleea angulosa, Hydrogonium arcuatum, Hymenostyliella, Hymenostylium aurantiacum, Luisierella barbula, Mniomalia, Rozea, Sphaerotheciella and Sorapilla among the mosses and Ceratolejeunea grandiloba, Drepanolejeunea subg. Rhaphidolejeunea, Lejeunea sect. Echinocolea, Lobatiriccardia, Myriocoleopsis sect. Myriocoleopsis, Phycolepidozia, Pictolejeunea, Rectolejeunea, Southbya organensis and Vitalianthus among liverworts. All of them occur in tropical or subtropical Asia and the Neotropics but are not known from Africa. The causes of the amphi-Pacific tropical disjunctions in bryophytes are still unclear. In flowering plants, molecular analyses indicate that amphi-Pacific tropical ranges frequently resulted from past migration across Eurasia and the northern Atlantic Ocean, followed by local extinction. This scenario may also have operated in amphi-Pacific bryophytes but some might have reached South America via the southern Pacific migration route. The possibility of direct long-range dispersal across the Pacific Ocean cannot be ruled out and this scenario seems likely for Southbya organensis, which occurs on Hawaii and freely produces spores and small gemmae. The possibility that the disjunctive ranges reflect insufficient collecting and that some taxa also occur in Africa should also be taken into account. There is no strong evidence for human introduction of amphi-Pacific tropical bryophytes. The new combinations Lejeunea sect. Echinocolea (R.M.Schust.) Gradst. comb. nov. and Myriocoleopsis sect. Protocolea (R.M.Schust.) Gradst. comb. nov. are proposed.

Sugar palm (Arenga pinnata) is a feather palm native to tropical Asia. In Vietnam, it is named Búng Báng or Đoác and grown only on the highlands in the central or northern part of Vietnam. It is utilized for many purposes, especially for Ta Vat wine production - a characteristic and unique product of Co Tu ethnic minority. However, because of the natural fermentation used in the production, the product quality is inconsistent. The purpose of this study was to examine a new procedure of using palm sap for making Ta Vat wine. Some characteristics of the sap, which was collected at Nam Giang district, Quang Nam province are determined, proving the potential of the sap for making wine product. The quality of sap changes quickly at room temperature. At low temperature (4 - 60C), the changes in sap quality are apparently slower. Examining some factors affecting its quality during the wine fermentation process, we determined the best parameters for the fermentation process as follows: inoculum size of 3% with cell density of about 1x108 cells/ml, the addition of the extract from the bark of Ceylon ironwood (Mesua ferrea L.) 4%. Keywords: Arenga pinnata, sap, Ceylon ironwood bark, Mesua ferrea L., wine fermentation.

RESUMO Por lo general, los historiadores de la ciencia reconocen la importaocia de Alexander von Humboldt en el desarrollo de la geografía moderna, si bien tal contribución especializada no es claramente desglosada de su multifacética producción científica. Con ocasión del bicentenario de su viaje a la América tropical, el papel de Humboldt en la formulación de las bases de una metodología analítica para la investigación geográfica, y su monumental trabajo sustantivo, lo mismo que su penetrante permanencia e inspiración en la tradición geográfica, deben acreditarse como justificación amplia y suficiente para su título de padre fundador de la geografía científica. Epígrafes: Humboldt, historia de la geografía, geografía moderna, metodología geográfica, exploración científica.ABSTRACT Alexander von Humboldt’s contributions to the development of modern geography are generally ackoowledged by historians of science, though not always stated precisely out of his many-sided scholarly production. On the occasion of the Bicentennial of his voyage to tropical America, Humboldt’s role in setting forth the foundation of an analytical methodology for geography as well as for his monumental substantive work, along with his pervasive and inspiring perrnanence in the geographical tradition, must be recognized as ample justification tu his title as founding father of scientific geography. Key words: Humboldt, history of geography, modern geography, geagraphical methodology, scientific exploration.
