| A recent collection of bats from northern Sulawesi (Celebes), Halmahera and Bacan (Batjan), Indonesia, contains representatives of three macroglossine genera. A specimen of Eonycteris rosenbergii (Jentink, 1889) from northern Sulawesi — a species previously known only from the immature type specimen — together with an additional, previously unreported specimen confirms the diagnostic value of the absence of the third lower molar. The validity of this taxon has been questioned by several authors, who suggested that E. rosenbergii is based on an anomalous specimen of E. spelaea (Dobson, 1871). Other material of Eonycteris from Sulawesi, referable to spelaea, is discussed, with the first record for the island of Muna (Moena), and comparative notes are given... |

| A partir de muestras colectadas en el litoral de la provincia de Cienfuegos se registraron cinco nuevos hallazgos de macroalgas marinas (rodofitas) para Cuba: Dasya ocellata (Gratel.) Harv. in Hook., Griffithsia schousboei Mont. in Webb var. anastomosans E.C. Oliveira, Gelidium torulosum Kützing, Halymenia pseudofloresii Collins & M. Howe y Champia vieillardii Kützing. Griffithsia schousboei var. anastomosans y Gelidium torulosum, que a su vez son nuevos registros para la región del Caribe, son dos taxa conocidos solo para Brasil. En el presente trabajo se ofrecen además comentarios sobre la taxonomía, ecología y biogeografía de las mencionadas especies. Destaca asimismo, la amplia variabilidad en tamaño y diámetro de las ramas de Halymenia... |

| The study of twenty-nine oligochaete samples collected in 1996 by J. H. Stock and J. J. Vermeulen (University of Amsterdam), in the Sultanate of Oman, allowed us to draw up an initial inventory of the freshwater oligochaete fauna of the Arabian peninsula, a fauna totally unknown until now. The 147 specimens examined belong to nine species of four families: Phreodrilidae, Naididae, Tubificidae and Enchytraeidae. The Phreodrilidae (2 species) represent more than half of the total specimens; whilst the rest belong mainly to the Naididae. Two new species of Phreodrilidae (Antarctodrilus arabicus n. sp. and Phreodrilus stocki n. sp.) are described. Both belong to the subfamily Phreodrilinae, until now not reported from north of the tropic of Capricorn. Other... |

| An annotated check-list concerning the molluscan fauna of the two highest peaks in the Parnon Oros, Peloponnisos, Greece, is provided, with emphasis on distributional data. The localities reported upon are situated only 15 km apart. Nevertheless, they are quite different in species composition. From one of these isolated peaks and from a second locality in another mountain range, Idyla pelobsoleta spec, nov., is described. The insular character of the two Parnon peaks, especially with regard to their clausiliid species, is emphasized. |

| As variacoes na densidade da cobertura vegetal arborea na regiao dos Cerrados tem recebido diversas denominacoes regionais ou o mesmo nome para fisionomias diferentes. E feita uma descricao dos tipos fisionomicos e sao acrescentadas algumas especies caracteristicas ou abundantes. Uma chave de identificacao e apresentada para diferenciar Mata de Galeria, Mata Mesofitica, Cerrado, Cerrado (Cerrado Denso, Cerrado Tipico, Cerrado Ralo, Parque de Cerrado e Vegetacao Rupestre de Altitude), Campo Sujo, Campo Limpo, Vereda. Os principais parametros utilizados na diferenciacao foram a estrutura da vegetacao (altura, estratificacao, percentagem de cobertura arborea) e as caracteristicas do solo (graus de umidade, profundidade e afloramento de rochas). |

| ABSTRACT Patterns of species diversity are essential to understand community structure. We aimed to determine species diversity and patterns of beta diversity in different spatial scales. We sampled three thousand individuals between the coordinates 22°10'S to 22°16'S and 47°47'W to 48°00'W to assess species diversity in three spatial scales (maximum distances of 80 m, 1,400 m, and 12,000 m), using the point-centered-quarter method. We partitioned gamma diversity into alpha and beta components. Beta diversity was partitioned into dissimilarities produced by spatial species turnover and nestedness. The contribution of beta diversity to gamma diversity was greater than that of alpha diversity in all scales, although the patterns of species diversity were... |

| Biogeography around South America is well documented on the Atlantic side and less well documented on the Pacific side especially south of about 30º S. The South Pacific oceanic areas are the least known of all pelagic areas. The different approaches to determine biogeographic provinces (e.g. the classical one showing mainly latitudinal and watermass distribution patterns based on presence/absence of species; and the biogeochemical approach based on productivity regimes and modelling) are discussed. The latter shows more east-west division. Testing of these concepts will probably reveal more coastal provinces in the Pacific area. The transitional area in the South Pacific is also an interesting area for molecular species research because there are some... |

| The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role of ecology in speciation, and patterns of species distribution in a typical reef-associated clade-the diverse and colorful Calcinus hermit crabs-to address the origin of tropical marine diversity. We sequenced COI, 16S, and H3 gene regions for similar to 90% of 56 putative species, including nine undescribed, "cryptic" taxa, and mapped their distributions. Speciation in Calcinus is largely peripatric at remote locations. Allopatric species pairs are younger than sympatric ones, and molecular clock analyses suggest that > 2 million years are needed for secondary sympatry. Substantial niche conservatism is evident within clades, as well as a few major... |

| Several species of “philosciid” Oniscidea are known from Brazil, most of them were found in the southern and eastern parts of this country. The genera Atlantoscia Ferrara & Taiti, 1981, Benthana Budde-Lund, 1908 and Balloniscus Budde-Lund, 1908, the latter considered to represent a separate family Balloniscidae Vandel, 1963, are considered the only neotropical philosciids bearing respiratory areas on their pleopods. Therefore, representatives of these genera are re-examined to shed new light on the question whether these species can be considered to be a monophylum with the autapomorphy “respiratory areas present”, The phytogeny of the above-mentioned genera is discussed under morphological and biogeographical aspects. Furthermore, a remarkable new... |

| Species of Euphrasia are distributed in both hemispheres with a series of connecting localities on the mountain peaks of Taiwan and the Malesian region including Luzon, Borneo, Sulawesi, Seram and New Guinea. Two hypotheses are proposed to explain this distribution pattern. The Northern Hemisphere might have been the centre of origin or the Southern Hemisphere. This study aims to reconstruct the core phylogeny of Euphrasia in the connecting areas and tries to identify the migratory direction of Euphrasia in Taiwan and Malesia. The phylogeny of Euphrasia, including sections Euphrasia, Malesianae and Pauciflorae, is reconstructed with the chloroplast molecular markers rps2 gene, trnL intron and trnL-trnF intergenic spacer. The results suggest that the... |
