| This study provides a list of anurans occuring in Londrina Municipality, north of Paraná, and analyses the difference in species richness between one well preserved forest area (Parque Estadual Mata dos Godoy) and another, altered area (Estação de Piscicultura da Universidade Estadual de Londrina). The greatest number of species was in the preserved area (24 species) when compared to the altered one (14 species). The occurence of true forest species (stenoics), such Crossodactylus sp., Eleutherodactylus binotatus, E. guentheri, and Hyalinobatrachium uranoscopum, only in the Parque Estadual Mata dos Godoy shows the conservation leveis of áreas and put in evidence the anurans as biological indicators of environmental quality.

| O Pantanal é um ecossistema extraordinário e importante para muitas espécies de aves, principalmente as aquáticas, que ocorrem em abundância, e as migrantes em larga escala que utilizam a planície de inundação como sítio de forrageio e descanso, durante seus deslocamentos entre o Sul do continente Americano e o Hemisfério Norte (Sick, 1997; Nunes e Tomas, 2004b; Nunes e Tomas, no prelo). Brown Jr. (1986) relaciona cerca de 657 espécies de aves para a planície e áreas limítrofes e Mittermeier et al. (2003) 463 espécies. No entanto Tubelis e Tomas (2003), listam 465 espécies de aves na planície, e citam outras 50 que podem ocorrer. Publicações mais recentes revelam a ocorrência de 17 novas espécies para a planície do Pantanal (Antas e Palo Jr., 2004;... |

| The topographical and hydrological complexity of submarine canyons, coupled with high substratum heterogeneity, make them ideal environments for cold-water coral (CWC) habitats. These habitats, including reefs, are thought to provide important functions for many organisms. The canyons incising the continental slope of the Bay of Biscay have distinct morphological differences from the north to the south. CWCs have been reported from this basin in the late 19th century; however, little is known about their present-day distribution, diversity and environmental drivers in the canyons. In this study, the characteristics and distribution of CWC habitats in the submarine canyons of the Bay of Biscay are investigated. Twenty-four canyons and three locations... |

| The distribution of Fe, Cu, Zn, Pb, Cd between the dissolved (<2 mu m) and the particulate (>2 mu m) fractions was measured after in-situ filtration in two hydrothermal habitats. The total metal concentration ranges exhibit a clear enrichment compared with the seawater concentration, accounting for the hydrothermal input for all the metals considered. Iron is the predominant metal (5-50 mu M) followed by Zn and Cu. Cd and Pb are present at the nM level. At the scale studied, the behavior of temperature, pH and dissolved iron is semi-conservative whereas the other dissolved and particulate metals are characterized by non-conservative patterns. The metal enrichment of the >2 mu m fraction results from the settlement and accumulation of particulate... |
