1. A new species of Arene (Vetigastropoda, Areneidae) from Canopus Bank, off NE Brazil
Abstract Arene lychee sp. nov. is described from Canopus Bank, a seamount located ~190 km off Fortaleza, Ceará, NE Brazil (02°14’25”S, 38°22’50”W), based on shell morphology. The species is characterized by a large, trochiform shell; color ranging from intense reddish to white (darker on spiral cords, lighter at base) with a yellow apex; sculpture

2. Occurrence and distribution of larval lanternfish (Myctophidae) from the southwest Atlantic Ocean
This study analyzes the occurrence and distribution of lanternfish (Myctophidae) larvae along the Brazilian coast (12-22ºS) between 200 m and the surface. Three cruises were conducted during the spring/1998, winter/1999 and autumn/2000. A total of 3,394 lanternfish larvae were identified representing 27 species and Lepidophanes guentheri (Goode & Bean, 1896

3. DinÃmica em microescala do mesozooplÃncton do ArquipÃlago de SÃo Pedro e SÃo Paulo â NE, Brasil
Plankton samples were collected (May/08) with a 300 μm mesh size net to assess smallscale variation patterns and for spatially comparisons among composition, distribution and abundance of the main zooplankton groups in Saint Peter and Saint Paul Archipelago (SPSPA). Sampling was carried out in two stations (Enseada and CabeÃo da Tartaruga) during five

4. Two Bacteria Phylotypes Are Predominant in the Suiyo Seamount Hydrothermal Plume
Microbial diversity and populations in a hydrothermal plume that was present inside the caldera of the Suiyo Seamount, a submarine volcano on the Izu-Bonin Arc, were investigated by performing a phylogenetic analysis of the 16S rRNA gene and by using fluorescence in situ hybridization (FISH). Corresponding to transmissivity, an indicator of turbidity, the ve

5. Neutrophilic Fe-Oxidizing Bacteria Are Abundant at the Loihi Seamount Hydrothermal Vents and Play a Major Role in Fe Oxide Deposition
A number of hydrothermal vent sites exist on the summit of the Loihi Seamount, a shield volcano that is part of the Hawaiian archipelago. The vents are 1,100 to 1,325 m below the surface and range in temperature from slightly above ambient (10°C) to high temperature (167°C). The vent fluid is characterized by high concentrations of CO2 (up to 17 mM) and Fe

6. Analysis of Dissimilatory Sulfite Reductase and 16S rRNA Gene Fragments from Deep-Sea Hydrothermal Sites of the Suiyo Seamount, Izu-Bonin Arc, Western Pacific
This study describes the occurrence of unique dissimilatory sulfite reductase (DSR) genes at a depth of 1,380 m from the deep-sea hydrothermal vent field at the Suiyo Seamount, Izu-Bonin Arc, Western Pacific, Japan. The DSR genes were obtained from microbes that grew in a catheter-type in situ growth chamber deployed for 3 days on a vent and from the effluen

7. Estimation of diversity and community structure through restriction fragment length polymorphism distribution analysis of bacterial 16S rRNA genes from a microbial mat at an active, hydrothermal vent system, Loihi Seamount, Hawaii.
PCR was used to amplify (eu)bacterial small-subunit (16S) rRNA genes from total-community genomic DNA. The source of total-community genomic DNA used for this culture-independent analysis was the microbial mats from a deep-sea, hydrothermal vent system, Pele's Vents, located at Loihi Seamount, Hawaii. Oligonucleotides complementary to conserved regions in th

8. Phylogenetic diversity of the bacterial community from a microbial mat at an active, hydrothermal vent system, Loihi Seamount, Hawaii.
The phylogenetic diversity of small-subunit rRNA genes associated with the domain Bacteria was examined (by using previously defined operational taxonomic units [C. L. Moyer, F.C. Dobbs, and D. M. Karl, Appl. Environ. Microbiol. 60:871-879, 1994]; those for Pele's Vents Bacteria are hereafter abbreviated PVB OTUs) with samples from a microbial mat at an acti

9. Isolation and characterization of novel iron-oxidizing bacteria that grow at circumneutral pH.
A gel-stabilized gradient method that employed opposing gradients of Fe2+ and O2 was used to isolate and characterize two new Fe-oxidizing bacteria from a neutral pH, Fe(2+)-containing groundwater in Michigan. Two separate enrichment cultures were obtained, and in each the cells grew in a distinct, rust-colored band in the gel at the oxic-anoxic interface. T
