| Para el estudio biológico y ambiental de la bahía de Jaramijó en los componentes fitoplancton, zooplancton, microbentos y macrobentos, se analizaron 15 estaciones provenientes de tres niveles entre 10 y 20 metros de profundidad y dividido en tres perfiles paralelos a la costa, durante las estaciones seca y lluviosa del año 2008. El fitoplancton y zooplancton resultaron muy abundantes durante la estaciòn lluviosa y menos abundante en la estación seca del año 2008. Predominaron las especies de diatomeas: Bacteriastrum hyalinum, Leptocylindrus danicus, Rhizósolenia stolterfothii, Chaetoceros affinis y Ch. curvisetus y la presencia de dinoflagelados y cianobacterias fue escasa dinoflagelados. En general las especies halladas son típicas de una mezcla de masas... |

| The St. Lucia System is found at the southern end of the Mozambique Floodplain and has a subtropical climate, warmed by the Agulhas current. Biogeographically, it lies at the interface between tropical and temperate biota, providing the northern distribution limits to a number of temperate species and the southern distribution limits to a number of tropical species. It has a high species diversity partly as a result of this position but also because of variability in both physical characteristics and soil conditions. |

| 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... |

| The assimilis species group is one of the several assemblages that can be distinguished within the genus Apostolepis. The group is characterized by a uniform red dorsal pattern, broad nucho-cervical collars, enlarged light snout blotch, dark ventral head, and entirely black terminal shield. A new species is here recognized as a member of the assimilis group and its phylogenetic relationships to A. assimilis and A. cearensis is inferred by means of cladistic analysis. Apostolepis ammodites sp. nov. can be easily diagnosed from all congeners by many autapomorphies and an exclusive combination of features. Comparative data are presented on scalation, coloration, dentition, osteology, and geographic distribution, with some notes on feeding and reproductive... |

| In uplands and lowlands of Santa Teresa, central Espírito Santo State, Brazil, 405 bird species were confirmed by field, museum, and literature studies. Of these, 16 seem to have disappeared, while 67 other species seem to have been lost from the lowlands (where no large biological reserves exist). Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps "invaded" with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often widespread, resulting in exchange of "Picassos for Coca-Cola bottles." Furthermore, gains exceed losses only when large biological reserves are present, as in the... |

| The objective of this work was to assess the soil oribatid mite communities in four sites of the Upper Paraná Bosque Atlántico, in the Iguazú National Park, Argentina and in surrounding areas: bamboo forest, palm forest and two mixed forests. A comparison between each pair of sites, based on the presence-absence of oribatid species, was performed using Jaccard's index. This is the first systematic sampling of oribatid mites in this area. A total of 56 genera and 96 oribatid species were found, 25 and 49 of them, respectively, are new citation for Argentina. The highest similarity was found between mixed forests. Almost 68% and 34% of the genera were cited for similar biotopes in Brazil and Paraguay, respectively. |

| We studied the flora of vegetation islands on rock outcrops on the Itatiaia Plateau (22°21'S and 44°40'W), at 2,400 m.a.s.l. A total of 114 vascular plant species, which correspond to ca. 20%-25% of the currently inventoried flora of the plateau, were sampled in 197 small vegetation islands (total area of 0.034 ha). Xerophytes and hydrophytes were often found side by side due to environmental heterogeneity at a small scale, explaining in part the high species diversity. Rock outcrops may support floras quite distinct from those in neighbouring habitats, due to the action of strong environmental filters, but in Itatiaia the geographic distribution patterns among rupicolous plants appear to mimic those described for the whole flora around it, with 15.1% of... |
