title: Aldegondabreen cryoconite Targeted Locus

description: The aggregation of surface debris (cryoconite) on melting glaciers into larger may provide microenvironments for various microorganisms and metabolic processes. Here we investigate the microbial community on the surface of Aldegondabreen, a valley glacier in Svalbard which is supplied with carbon and nutrients from different sources across its surface, including colonies of seabirds. We used a combination of geochemical analysis (surface debris, ice and meltwater), quantitative PCR (targeting the 16S rRNA and amoA genes), pyrosequencing and multivariate statistical analysis to better understand the ecology of prokaryotic microbes on the surface on Aldegondabreen and their role in nitrogen cycling. The combination of high nutrient input, supraglacial melt water flow and the presence of fine, claylike particles supports the formation of cmscale cryoconite aggregates in some areas of the glacier surface. We show that a diverse microbial community is present, dominated by the cyanobacteria, Proteobacteria, Bacteroidetes, and Actinobacteria, that are wellknown in supraglacial environments. Allochthonous material including plant tissuederived chloroplasts was also identified in the molecular analysis. Importantly, ammonia oxidizing archaea (AOA) were detected in the aggregates for the first time on an Arctic glacier.

title: Deep Sea Sponge and Seawater Targeted Locus (Loci)

description: The microbiota of four individual deep water sponges, Lissodendoryx diversichela, Poecillastra compressa, Inflatella pellicula, and Stelletta normani, together with surrounding seawater were analysed by pyrosequencing of a region of the 16S rRNA gene common to Bacteria and Archaea. The microbial communities of L. diversichela, P. compressa and I. pellicula were typical of low microbial abundance (LMA) sponges while S. normani was found to have a community more typical of high microbial abundance (HMA) sponges. Analysis of the deep sea sponge microbiota revealed that the three LMA-like sponges shared a set of abundant OTUs that were distinct from those associated with sponges from shallow waters.

title: Development and validation of a marine experimental life support system for accessing synergistic effects of climate change and oil pollution on microbial communities

description: A state of the art marine experimental life support system framework was developed to perform microcosms experiments of climate change and anthropogenic pollutants effects on marine microbial communities. The system can be build with commercially available materials, enabling the reproduction of the same experiment in several locations worldwide. Here the system was validated for microbial ecology studies by comparing the bacterial composition of environmental and microcosm samples with a RNA-based barcode pyrosequencing approach. The OTU composition shift towards anaerobic bacterial groups in manipulates samples, witch can be explained with the operational programme executed. Replicate microcosm maintained a high OTU composition stability, with similar variability to the environmental samples. This system can be use to establish cause-effect relationships into the effects of climate change and other anthropogenic stressors on specific marine microbial communities. Moreover, the marine experimental life support system versatile design enables its use on ecotoxicology tests.

title: Ice Wedge Polygon

description: Frozen soil samples were collected that represent topographically high and low areas from basins of various ages around Barrow, Alaska. All of the sites are coordinated with portable or permanent Eddy covariance towers that have been used to study gas exchange. The samples were collected from several transects that include polygon rims and centers. At each site two cores were taken from rims and three from centers. The cores were approximately 25 cm deep, and so only include the active layer. Specifically samples were obtained from matching sets of polygon rims and centers from 3 different basins. This produced 24 samples: 3 basins x 2 types (rim/center) x 4 depths (6-10, 16-20, 26-30, 36-40cm). These were supplemented with smaller cores from additional basins: 3 basins x 2 types x 2 depths (6-10, 16-20cm). For the samples high refers to polygon rims, low to polygon centers. Additional abundant biological and chemical metadata have been collected for these samples.

title: Microbial Community Diversity Response to a Changing Arctic Ocean

description: Increasing global temperatures are having a profound impact in the Arctic, including the dramatic loss of multiyear sea ice in 2007 that has continued to the present. The majority of life in the Arctic is microbial and the consequences of climate-mediated changes on microbial marine food webs, which are responsible for biogeochemical cycling and support higher trophic levels, are unknown. We examined microbial communities over time by using high-throughput sequencing of microbial DNA collected between 2003 and 2010 from the subsurface chlorophyll maximum (SCM) layer of the Beaufort Sea (Canadian Arctic). We found that overall this layer has freshened and concentrations of nitrate, the limiting nutrient for photosynthetic production in Arctic seas, have decreased. We compared microbial communities from before and after the record September 2007 sea ice minimum and detected significant differences in communities from all three domains of life. In particular, there were significant changes in species composition of Eukarya, with ciliates becoming more common and heterotrophic marine stramenopiles (MASTs) accounting for a smaller proportion of sequences retrieved after 2007. Within the Archaea, Marine Group I Thaumarchaeota, which earlier represented up to 60% of the Archaea sequences in this layer, have declined to &lt;10%. Bacterial communities overall were less diverse after 2007, with a significant decrease of the Bacteroidetes. These significant shifts suggest that the microbial food webs are sensitive to physical oceanographic changes such as those occurring in the Canadian Arctic over the past decade.

title: Oceanic microplankton do not adhere to the latitudinal diversity gradient

description: A latitudinal biodiversity gradient has captivated ecologists for years, and has become a widely recognized pattern in biogeography, manifest as an increase in biodiversity from the poles to the tropics. Oceanographers have attempted to discern whether these distribution patterns are shared with marine biota, and a lively debate has emerged with regard to the global distribution of microbes. Limitations in sampling resolution for such large-scale assessments have often prohibited definitive conclusions. This investigation has evaluated microbial planktonic communities along a ~15,400 km Pacific Ocean transect with DNA from samples aquired every 2 degrees of latitude within a three month period between late August to early November, 2003. Next generation sequencing targeted Bacteria, Archaea, and Eukarya rDNA sequences.Beta analysis of ~10.8 million high quality sequences showed significant geographic patterns of microbial communities, primarily the Bacteria and Archaea domains. Despite regional clustering, none of the domains exhibited a unimodal pattern of alpha-diversity with respect to latitude. Bacteria communities increased in richness from Arctic to Antarctic waters; whereas Archaea and Eukarya communities showed no latitudinal or polar trends. Based on these analyses, constraints on macrofaunal response to factors related to latitude may not be defining prokaryotic and eukaryotic microorganism diversity patterns in the global ocean.

description: Resumo: Os portais de periódicos científicos constituem um importante recurso de apoio à produção e à disseminação dessas publicações no país, onde o exercício da atividade de editoria científica – centrado nas instituições de ensino superior públicas – enfrenta enormes desafios. Diversos trabalhos relatam a implantação de portais em universidades brasileiras e revelam que serviços de apoio aos periódicos e políticas de desenvolvimento das coleções são fundamentais para garantir a qualidade das publicações, mas exigem esforço de coordenação nas instituições. O presente estudo visa investigar os portais das instituições de ensino superior públicas brasileiras identificando se possuem políticas publicadas, que serviços oferecem e quem são os responsáveis por eles nas instituições. De natureza descritiva, o estudo investiga 289 instituições identificadas nos microdados do censo da educação superior e, como métodos, utiliza pesquisa documental, análise de conteúdo e estatísticas descritivas. Como resultados, foram identificados 139 portais vinculados a 132 instituições (46% da população), dos quais 26% trazem informações sobre serviços oferecidos, sendo os mais comuns os de assessoria e capacitação e de controle, normalização, edição e indexação; 35% possuem políticas de desenvolvimento de coleções; e cerca de 65% identificam as unidades responsáveis por sua gestão. Embora revelem um crescimento significativo no número de portais na comparação com estudos anteriores, especialmente entre as universidades federais, os resultados sugerem haver espaço para o desenho de políticas públicas e institucionais específicas para estimular a institucionalização dos portais, mirando o aperfeiçoamento das políticas de desenvolvimento de coleções e o incremento da oferta de serviços para as publicações.
