Microbial community in the sediment of the arctic Smeerenburgfjorden

Fluorescence in situ hybridization (FISH) with 16S rRNA-targeted oligonucleotide probes were used to investigate the phylogenetic composition of a marine Arctic sediment (Svalbard). Hybridization and microscopy counts of hybridized and 4',6'-diamidino-2-phenylindole (DAPI)-stained cells were performed as described previously from Snaidr et al. (1997, http://aem.asm.org/content/63/7/2884.full.pdf). Means were calculated from 10 to 20 randomly chosen fields on each filter section, corresponding to 800 to 1,000 DAPI-stained cells. Counting results were always corrected by subtracting signals observed with the probe NON338. Formamide concentrations are given in further details. FISH resulted in the detection of a large fraction of microbes living in the top 5 cm of the sediment. Up to 65.4% ± 7.5% of total DAPI cell counts hybridized to the bacterial probe EUB338, and up to 4.9% ± 1.5% hybridized to the archaeal probe ARCH915. Besides delta-proteobacterial sulfate-reducing bacteria (up to 16% 52) members of the Cytophaga-Flavobacterium cluster were the most abundant group detected in this sediment, accounting for up to 12.8% of total DAPI cell counts. Furthermore, members of the order Planctomycetales accounted for up to 3.9% of total cell counts. In accordance with previous studies, these findings support the hypothesis that these bacterial groups are not simply settling with organic matter from the pelagic zone but are indigenous to the anoxic zones of marine sediments. Members of the gamma-proteobacteria also constituted a significant fraction in this sediment (6.1% ± 2.5% of total cell counts). A new probe (GAM660) specific for sequences affiliated with free-living or endosymbiotic sulfur-oxidizing bacteria was developed. A significant number of cells was detected by this probe (2.1% ± 0.7% of total DAPI cell counts), showing no clear zonation along the vertical profile. Gram-positive bacteria and the beta-proteobacteria were near the detection limit in all sediments.

The benthic foraminiferal community in a naturally CO2-rich coastal habitat of the southwestern Baltic Sea

It is expected that the calcification of foraminifera will be negatively affected by the ongoing acidification of the oceans. Compared to the open oceans, these organisms are subjected to much more adverse carbonate system conditions in coastal and estuarine environments such as the southwestern Baltic Sea, where benthic foraminifera are abundant. This study documents the seasonal changes of carbonate chemistry and the ensuing response of the foraminiferal community with bi-monthly resolution in Flensburg Fjord. In comparison to the surface pCO2, which is close to equilibrium with the atmosphere, we observed large seasonal fluctuations of pCO2 in the bottom and sediment pore waters. The sediment pore water pCO2 was constantly high during the entire year ranging from 1244 to 3324 µatm. Nevertheless, in contrast to the bottom water, sediment pore water was slightly supersaturated with respect to calcite as a consequence of higher alkalinity (AT) for most of the year. Foraminiferal assemblages were dominated by two calcareous species, Ammonia aomoriensis and Elphidium incertum, and the agglutinated Ammotium cassis. The one-year cycle was characterised by seasonal community shifts. Our results revealed that there is no dynamic response of foraminiferal population density and diversity to elevated sediment pore water pCO2. Surprisingly, the fluctuations of sediment pore water undersaturation (Omega calc) co-vary with the population densities of living Ammonia aomoriensis. Further, we observed that most of the tests of living calcifying foraminifera were intact. Only Ammonia aomorienis showed dissolution and recalcification structures on the tests, especially at undersaturated conditions. Therefore, the benthic community is subjected to high pCO2 and tolerates elevated levels as long as sediment pore water remains supersaturated. Model calculations inferred that increasing atmospheric CO2 concentrations will finally lead to a perennial undersaturation in sediment pore waters. Whereas benthic foraminifera indeed may cope with a high sediment pore water pCO2, the steady undersaturation of sediment pore waters would likely cause a significant higher mortality of the dominating Ammonia aomoriensis. This shift may eventually lead to changes in the benthic foraminiferal communities in Flensburg Fjord, as well as in other regions experiencing naturally undersaturated Omega calc levels.

Meiofauna and the structure of the benthic community in the Iberian deep sea basin

1. On the cruises 3 and 15 of R.V. "Meteor" 6 grab samples, and 6 hauls with the 6 m Agassiztrawl were taken and at 2 stations the deep sea camera was lowered. This material gave quantitative results on the meiofauna and minimum counts of the macrofauna. 2. The nematodes constitute nearly 95% of the meiofauna, the copepoda only 2%. With increasing sediment depth the density of animals decrease gradually. In the uppermost centimeter of sediment 42.6% of the meiofauna are found while only 3.7% live in layer 6-7 cm. Meiofauna weight ranges from 0.6-5.7 mg/25 m**2 surface i.e. 0.24-2.8 g/m**2. 3. Mean numbers of individuals and weights show standard errors of 20-30 %. As an approximate average values for further considerations the weight of the meiofauna in the area was taken as 1 g/m**2 4. Quantitative information on the macrofauna is derived from the trawls and the photographs for the actinia Chitonanthus abyssorum only, which is found in the rate of 1 individual/36-72 m**2, but seems to be less abundant generally. 5. Animal density does not decrease steadily from nearshore to offshore biocoenoses, i.e. generally with increasing depth. The decrease is more pronounced for macro- than for meiofauna. For the deep sea the weight proportion of macrofauna : meiofauna is of the order of 1 : 1. 6. With the assumption, that adaptation of metabolism to deep sea conditions is similar in macro- and meiofauna total metabolism of invertebrates is ascribed to meiofauna to more than 80%. 7. The structure of the biocoenosis of the deep sea floor is characterized by the meiofauna living on and in the sediment and by the dominance of sediment feeders in the macrofauna. 8. Considering the large numbets and high partition rates of bacteria a comparative large part of the metabolism in the deep sea sediment must be ascribed to bacteria. This favours the hypothesis, that with increasing depth and decreasing addition of organic material to the sediment, the importance of meiofauna and microorganisms for total metabolism increases. 9. Considering the different modes of food transport to the deep sea environment, i.e. sinking of dead particles, transport by vertical migration of organisms, aggregation of organic particles, adsorption of dissoloved organic substance to inorganic particles, and heterotrophy, the sediment may be assumed to contain more food for invertebrates than the water above the bottom. 10. Suspensions feeders of macrofauna are fixed to hard substrates in the sediment surface. Some of them are shown to bend themselves down to the bottom in underwater photographs. This suggests the idea that some deep sea suspension feeders partly depend on food from the sediment surface, on which they feed directly.

Heatwave planning: the role of the community in co-producing resilience

Drawing on a thematic analysis of relevant policy documents, the aim of this paper is to comment on an apparent disconnect between two associated contemporary UK policy areas: planning for heatwaves and community resilience. Regional and national policy documents that plan for heatwaves in the UK tend to focus on institutional emergency responses and infrastructure development. In these documents, although communities are mentioned, they are understood as passive recipients of resilience that is provided by active institutions. Meanwhile, contemporary discussion about community resilience highlights the potential for involving communities in planning for and responding to emergencies (although the concept is also the subject of critique). Within this context, the paper proposes that – through engagement with the ‘community resilience’ policy agenda and its critique – effort should be made to articulate and realise greater participation by individuals, and voluntary and community sector groups in heatwave preparation, planning and response.

Diversity and television in Argentina: the case of the Audiovisual Technology Hub Programme

This paper describes and analyses the Audiovisual Technology Hub Programme (Programa Polos Audiovisuales Tecnológicos - PPAT), which has been implemented in Argentina between 2010 and 2015 as part of the public policy of former administration of Cristina Fernández de Kirchner. The main goal was to promote a television industry that reflects the cultural diversity of Argentina by dividing the national territory in nine into nine audiovisual technology hubs, where national public universities acted as centres that gathered a range of regional stakeholders. Considering the 18 TV seasons that were produced for television between 2013 and 2014, the text analyses the diversity of sources and genres / subgenres and its restricted marketing. The article closes with a brief set of conclusions about this initiative.

Temporary contracts and non-protected employment in Argentina, Chile and Perú: incidence and determinants

The diverse kinds of legal temporary contracts and the employment forms that do not comply with legal requirements both facilitate employment adjustment to firms´ requirements and entail labour cost reductions. Their employment incidence depends not only on the economic and labour market evolutions but also on other factors, in particular the historical trajectories followed by labour legislation, state enforcement, and the degree of compliance. To contribute to the understanding of the determinants of the degree of utilization of different employment practices, the study reported in this article explores the use made of the various legal temporary contracts and of precarious employment relationships by private enterprises in three Latin American countries (Argentina, Chile and Peru) during 2003-2012, a period of economic growth, and the explanatory role of diverse factors.

Waged domestic work in Argentina: the regulation of care provision

This paper addresses the condition of domestic work in Argentina, in a perspective that draws from the literature on care work. In this approach, domestic work can be interpreted as one of the mercantile forms in which care work is socially organized, due to the persistence of the traditional sexual division of labor and the weakness of public policies. From these considerations, I develop a quantitative study on the levels of informality, precarity, and wage inequality that characterize domestic work in that country. Thereafter, I discuss the main measures adopted by the Argentine government since 2003, with the goal of reducing legal discrimination of domestic workers and promoting their formalization. On this basis, the paper highlights the advances in the recognition of domestic workers’ labor rights, while emphasizing how social and cultural restraints still permeate labor relations in this sector.

Community in Modern Scottish Literature.

Community in Modern Scottish Literature is the first book to examine representations and theories of community in Scottish writing of the twentieth and twenty-first centuries across a broad range of authors and from various conceptual perspectives. The leading scholars in the field examine work in the novel, poetry, and drama, by key Scottish authors such as MacDiarmid, Kelman, and Galloway, as well as less well known writers. This includes postmodern and postcolonial readings, analysis of writing by gay and Gaelic authors, alongside theorists of community such as Nancy, Bauman, Delanty, Cohen, Blanchot, and Anderson. This book will unsettle and yet broaden traditional conceptions of community in Scotland and Scottish literature, suggesting a more plural idea of what community might be.
