| Aim Deep-sea hydrothermal vents have now been reported along all active mid-ocean ridges and back-arc basins, but the boundaries of biogeographic entities remain questionable owing to methodological issues. Here we examine biogeographic patterns of the vent fauna along the East Pacific Rise (EPR) and determine the relative roles of regional and local factors on the distribution of biodiversity associated with mussel beds along a poorly explored zone, the southern EPR (SEPR). Location East Pacific Rise. Methods A species list of macrobenthic invertebrates along the EPR was compiled from the literature and supplemented with data recovered during the French research cruise BIOSPEEDO carried out in 2004 along the SEPR. Biogeographic patterns were assessed by... |

| Brazil is the second most bat species-rich country in the world, but the information on its species diversity, occurrence and distribution is still heterogeneous and fragmented. None of the Brazilian biomes are well surveyed for bats, but this situation is more critical in Amazonia, an area covering nearly 2/3 of the country. Here we provide updated information on the bats of Amapá, once a data gap in the diversity and distribution of bats in the easternmost Amazonia, and the Guiana Shield as well. Rapid biological assessments (5,551 mistnet.hours) were conducted in conservation units and areas of concern, resulting in 1,695 captures, 59 species, 36 genera and six families for the State. New records for the state and for the Guiana Shield area are... |

| Pelagic species are widely distributed in a horizontal plane and have three-dimensional distributions, since the sea covers about 70% of the surface of the earth, and on average 4 km deep. For most macrozooplankton and micronekton groups there seems to be no great expectations of finding new taxa with the exception of gelatinous groups and of the deep sea, which is a relatively unknown especially in the benthopelagic zone close to the sea-bed. However, we do not know very much about variation, either morphological or genetical, within socalled species in different parts of their range. We think we are dealing with single very broadly distributed species, which, in reality, are species complexes consisting of several more or less cryptic species or... |

| ABSTRACT The sciaenid genus Bairdiella comprises a group of relatively small fishes found in inshore waters and estuaries of the western Atlantic and eastern Pacific. Despite recent analyses of the phylogenetic relationships of Bairdiella, there has been no comprehensive revision of the alpha taxonomy of the species of the genus. Bairdiella ronchus from the western Atlantic, has a complex taxonomic history, with four junior synonyms recognized. Based on morphological and molecular evidence, this study indicates that B. ronchus represents a species complex. The species is therefore redescribed and its geographic range is redefined. Bairdiella veraecrucis, which is currently recognized as a junior synonym of B. ronchus, is revalidated, and a new species of... |
