| Coming from Oriental Asia and Siberia, the Cyprinidae reached the Iberic Peninsula probably at the end of the Oligocene. Their populations bore speciation processes which led to the formation of a fauna rich in endemic species and subspecies. Populations of two of the genera Barbus and Pseudophoxinus reached Northwestern African forming there several endemic species. Concerning the speciation forms, it is probable that the allopatric form, whether by foundation effect or by subdivision, played an important part. Pyrenees and Mediterranean Sea settled probably efficient barriers for the Iberic Cyprinidae isolation. The present geographical repartition of Cyprinidae in Iberic Peninsula suggests that altitude lines and glaciations which reached the north of... |

| 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). |

| The biogeogeographical distribution of Platasterias latiradiata Gray, considered a "living fossil" is extended to Ecuador, which has been founded close to the coast of Mexico and Central America. A map gives the new distribution, as well as a comparative study of the external morphology in a similar way as the reports and contributions of Caso, M. (1961, 1976). It is also included a table with measurements of several parts of the body, considered of taxonomic importance and pictures, showing predation on the gastropod, Olivella semistriata like one of its common food of preference. |

| Se amplía la distribución biogeográfica de Platasterias latiradiata (Gray), hasta el Ecuador, considerada un fósil viviente, la que ha sido encontrada sólo en el Pacífico Litoral mexicano y centroamericano. En un mapa se da a conocer la nueva distribución, así como también un estudio comparativo de la morfología externa de una manera similar a los reportes y contribuciones de Caso, M, (1961, 1970, 1976). También se incluye una tabla con las medidas de algunas partes del cuerpo consideradas de importancia taxonómica y fotografías mostrando la predación de gasterópodos (Olivela semistriata) como uno de sus alimentos preferidos. |

| 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... |

| Sixteen species of marine Haplosclerida were collected by the CANCAP-expeditions, among which two are new to science, viz. Petrosia canariensis and Oceanapia cancap. The Haplosclerida fauna of the south-eastern part of the North Atlantic, comprising 46 species, is reviewed, discussed and compared with those of neighbouring areas of the North Atlantic (NE Atlantic, W Atlantic, West Indies, Mediterranean). Three distribution patterns are recognized: Mediterranean-Atlantic, endemic and amphi-Atlantic. |

| The five known species of the African genus Chondrolepis Mabille are extensively described and figured and two new species are added. Keys are given to the males and females separately. Most species are restricted to montane habitats, mainly in East Africa. Based on their phylogeny the geographic history of the species is analyzed. It is concluded that the distribution agrees with the predictions to be derived from the hypotheses that montane forests were very much restricted during the last Glacial Period of the Northern Hemisphere, later on becoming more widespread than at present, and that the contact between the Cameroun highlands and the highlands of East Africa was through species that temporarily lived in the intervening lowland forests and not... |

| In the world, the Ampelisca genus is constituted by more than 140 species, which are found between 0 to 4000 m depth. Phylogeny, biology and ecology are the most important interest in this genus. The present analysis of new and older collections (E. Chevreux) have permitted to describe 11 new species. 41 species are listed in the north-eastern Atlantic fauna. These are different arguments to think that Ampelisca groups was actually in speciation. Two groups issued from a phenetic analysis are discriminated by their apomorphic levels. More than of the third are endemic species. 21 species are present only in one of the five biogeographic region. 23 species are limited to the continental shelf, 34 live up to the first 1000 meters and 4 are bathyal. 2 species... |

| An updated list of more than 350 <i>Artemia</i> sites is provided. It includes geographical coordinates of the sites and available data on the mode of reproduction of the locally occurring brine shrimp.The geographical distribution of <i>Artemia</i> is related to different types of climate. The classification of climate according to Thornthwaite provides a good correlation with the geographical occurrence of <i>Artemia</i> , as a result of which the world distribution pattern of <i>Artemia</i> can be predicted. Moreover, areas with possible <i>Artemia</i> sites and areas suited for transplantation and/or inoculation with <i>Artemia</i> can be identified on the basis of water balance... |

| O gênero Philodendron se divide em três subgêneros, cada um com distintos padrões de morfologia, anatomia e distribuição. Em análise filogenética, o subgêneiro Meconostigma, o único com centro de especiação no sudeste do Brasil, mostra-se bastante apomórfico, ainda que cladisticamente primitivo no gênero. Análises fenéticas mostram que o gênero se constitue um taxon distinto, apesar de não ter um só caráter definitivo. Mostram também que feneticamente, Philodendron está mais perto de certos gêneros da África ocidental (Culcasia, Cercestis, Rhektophyllum) do que dos gêneros principalmente asiáticos com os quais está ligado pela classificação tradicional. A morfologia do gineceu varia muito no subgênero Meconostigma, com as formas mais simples ocorrendo no... |

| The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and... |
