1. Análisis panbiogeográfico del género Galianthe subgénero Ebelia (Rubiaceae)
Abstract Galianthe (Rubiaceae: Spermacoceae) is a genus composed by the subgenus Galianthe and Ebelia, the latter includes 11 Neotropical species with a center of diversity located in Brazil. The panbiogeographic analysis emphasizes the importance of the spatial dimension of biodiversity to generate a better understanding of both, evolutionary patterns and p

2. Macroecologia do zooplâncton continental: padrões latitudinais e componentes locais e regionais na determinação da diversidade global / Macroecology of continental zooplankton: latitudinal patterns and local and regional components in determining global diversity
One of the oldest and best known global biological patterns in ecology is the latitudinal gradient of richness, characterized by a decrease in the number of species from Equator toward the poles. Several hypotheses, even today, attempt to explain the variation that occurs in the pattern of diversity of many animal and plants. Despite the advances that have b

3. Mithracinae (Decapoda: Brachyura) from the Brazilian coast: review of the geographical distribution and comments on the biogeography of the group
The geographical distribution of marine organisms, as a result of complex natural processes through geological time, has been changed, sometimes drastically, by species introductions. Instances of species introduction have been recorded worldwide, and the Brazilian coast is no exception. The present review provides an update of the geographical distribution

4. Biogeografia e sistemática dos peixes aulopiformes / Biogeography and systematics of aulopiformes fishes
The Aulopiformes are marine fishes ranging from Early Cretaceous to Recent. Fossil taxa are found in sediments from South and North America, Europe, Asia and Africa. The living forms can be found from shallow coastal estuaries, to the abyssal depths, exceeding 3,000 m. Interrelationships among this group are subject of many studies. The aim of these studies

5. What are and where are the bioactive terpenoids metabolites from Dictyotaceae (Phaeophyceae)
Dictyotaceae are a rich source of secondary metabolites, especially terpenes. These natural products have been studied for their bioactivity for human and for their ecological role in nature. The present work highlights de diversity of the Dictyotaceae terpenes, emphasizing their bioactivities and the biogeography of their sources. The sesquiterpenes are fou

6. Archaeozoology of marine mollusks from Sambaqui da Tarioba, Rio das Ostras, Rio de Janeiro, Brazil
A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belong

7. Molecular Systematics and Biogeography of Monogenoidea (Platyhelminthes: Cercomeromorpha), Gill Parasites of Potamotrygonidae (Chondrichthyes: Rajiformes: Myliobatoidei) / Sistemática molecular e biogeografia dos Monogenoidea (Platyhelminthes: Cercomeromorpha), parasitas das brânquias de Potamotrygonidae (Condrichthyes: Rajiformes: Myliobatoidei)
South America is the only biogeographical region in the world where is possible to find an exclusive stenohalin group of elasmobranchs: the Potamotrygonidae stingrays. Between 19 and 21 species of potamotrygonid stingrays are taxonomically organized in three genera, distributed in the Atrato, Magdalena, Maracaibo, Orinoco, Essequibo, Amazonas e la Plata rive

8. Ecologia e taxonomia da associaÃÃo de Copepoda Harpacticoida no talude da Bacia de Campos , RJ, Brasil
Taxonomy and ecology of Copepoda Harpacticoida from sediments of Campos Basin Slope are presented here (chapter 1), as well as the description of threee new species of Echinopsyllus (chapter 2) and a discussion concerning new insights for geographic and bathyme tric distribution of Ancorabolidae (chapter 3). A total of 44 stations were sampled along nine tra

9. The historical biogeography of Pteroglossus aracaris (Aves, Piciformes, Ramphastidae) based on Bayesian analysis of mitochondrial DNA sequences
Most Neotropical birds, including Pteroglossus aracaris, do not have an adequate fossil record to be used as time constraints in molecular dating. Hence, the evolutionary timeframe of the avian biota can only be inferred using alternative time constraints. We applied a Bayesian relaxed clock approach to propose an alternative interpretation for the histor

10. Microbial Biogeography along an Estuarine Salinity Gradient: Combined Influences of Bacterial Growth and Residence Time
Shifts in bacterioplankton community composition along the salinity gradient of the Parker River estuary and Plum Island Sound, in northeastern Massachusetts, were related to residence time and bacterial community doubling time in spring, summer, and fall seasons. Bacterial community composition was characterized with denaturing gradient gel electrophoresis

11. Linking biogeography to physiology: Evolutionary and acclimatory adjustments of thermal limits
Temperature-adaptive physiological variation plays important roles in latitudinal biogeographic patterning and in setting vertical distributions along subtidal-to-intertidal gradients in coastal marine ecosystems. Comparisons of congeneric marine invertebrates reveal that the most warm-adapted species may live closer to their thermal tolerance limits and hav

12. Coupled biophysical global ocean model and molecular genetic analyses identify multiple introductions of cryptogenic species
The anthropogenic introduction of exotic species is one of the greatest modern threats to marine biodiversity. Yet exotic species introductions remain difficult to predict and are easily misunderstood because knowledge of natural dispersal patterns, species diversity, and biogeography is often insufficient to distinguish between a broadly dispersed natural p
