The Family

A new genus and species of the family Phoxocephalidae is here described with material collected during the Mini Biological Trawl Project at 224 and 500 m depth off Brazil’s southeastern coast in the states of Rio de Janeiro and São Paulo. Atlantiphoxus wajapi n. gen., n. sp. can be grouped in the subfamily Phoxocephalinae and seems to be morphologically close to Fuegiphoxus Barnard and Barnard, 1980 and Parharpinia Stebbing, 1899. However it can be easily distinguished within the phoxocephalids by the following characters: deep pereonites with small coxae; rostrum unconstricted; eyes absent; man­dible molar not triturative, but as a small hump with 3 multicuspidate stout setae; pereopods 3-4 with stout dactylus; pereopod 5 basis strongly tapering distally; pereopod 7 basis anterodistal corner with a row of long plumose setae; dactylus elongate. Epimeral plate 3 posteroventral margin strongly produced.

Current Record

Six species of deep sea decapod crustaceans (Chaceon gordonae, Bathynectes longispina, Dromia bollorei, Homola mini-ma, Nematocarcinus gracilipes and Plesionika martia) were sampled around the vicinity of São Pedro and São Paulo Archipelago, Brazil (0°55´N; 29°21´W), after nine scientific surveys to explore demersal and benthic species in the area. Specimens were collected by bottom traps between 200 and 700 m deep, from 2012 to 2015. The current record enlarges the knowledge of the distribution of five of these species, new to the Archipelago. Chaceon gordonae was previously known to the area.

A New Species

An unfamiliar gastropod was collected from a deep-sea whale carcass at the base of the São Paulo Ridge in the Southwest Atlantic by the manned research submersible Shinkai 6500, and is here described as a new species of the abyssochrysoidean genus Rubyspira, R. brasiliensis sp. nov., following morphological and molecular phylogenetic examinations. There are only two other known species in the genus, which occur together in the Monterey Submarine Canyon off California. The present new species was shown by the molecular analysis to be closer to one of the Californian species than the other. It was found aggregated on and around a whale carcass at a depth of 4204 m, which represents the deepest record of whale- fall ecosystems ever discovered.

AbstractHere we investigated the diversity of bacterial communities from deep-sea surface sediments under influence of asphalt seeps at the Sao Paulo Plateau using next-generation sequencing (NGS) method. Sampling was performed at North São Paulo Plateau using the human occupied vehicle Shinkai 6500 and her support vessel Yokosuka. The microbial diversity was studied at two surficial sediment layers (0-1 and 1-4 cm) of five samples collected in cores in water depths ranging from 2,456-2,728 m. Bacterial communities were studied through sequencing of 16S rRNA gene on the Ion Torrent platform and clustered in operational taxonomic units. We observed high diversity of bacterial sediment communities as previously described by other studies. When we considered community composition, the most abundant classes were Alphaprotebacteria (27.7%), Acidimicrobiia (20%), Gammaproteobacteria (11.3%) and Deltaproteobacteria (6.6%). Most abundant OTUs at family level were from two uncultured bacteria from Actinomarinales (5.95%) and Kiloniellaceae (3.17%). The unexpected high abundance of Alphaproteobacteria and Acidimicrobiia in our deep-sea microbial communities may be related to the presence of asphalt seep at North São Paulo Plateau, since these bacterial classes contain bacteria that possess the capability of metabolizing hydrocarbon compounds.

Over Time

Background: In light of the few reports from intertropical latitudes and their conflicting results, we aimed to replicate and update the investigation of seasonal patterns of suicide occurrences in the city of São Paulo, Brazil. Methods: Data relating to male and female suicides were extracted from the Mortality Information Enhancement Program (PRO-AIM), the official health statistics of the municipality of São Paulo. Seasonality was assessed by studying distribution of suicides over time using cosinor analyses. Results: There were 6,916 registered suicides (76.7% men), with an average of 39.0 ± 7.0 observed suicides per month. For the total sample and for both sexes, cosinor analysis estimated a significant seasonal pattern. For the total sample and for males suicide peaked in November (late spring) with a trough in May–June (late autumn). For females, the estimated peak occurred in January, and the trough in June–July. Conclusions: A seasonal pattern of suicides was found for both males and females, peaking in spring/summer and dipping in fall/winter. The scarcity of reports from intertropical latitudes warrants promoting more studies in this area.
