Microbiota and Microsatellite genotypes of Pacific oysters stemming from three oyster bed in the Northern Wadden Sea

Background: Studies of oyster microbiomes have revealed that a limited number of microbes, including pathogens, can dominate microbial communities in host tissues such as gills and gut. Much of the bacterial diversity however remains underexplored and unexplained, although environmental conditions and host genetics have been implicated. We used 454 next generation 16S rRNA amplicon sequencing of individually tagged PCR reactions to explore the diversity of bacterial communities in gill tissue of the invasive Pacific oyster Crassostrea gigas stemming from genetically differentiated beds under ambient outdoor conditions and after a multifaceted disturbance treatment imposing stress on the host. Results: While the gill associated microbial communities in oysters were dominated by few abundant taxa (i.e. Sphingomonas, Mycoplasma) the distribution of rare bacterial groups correlated to relatedness between the hosts under ambient conditions. Exposing the host to disturbance broke apart this relationship by removing rare phylotypes thereby reducing overall microbial diversity. Shifts in the microbiome composition in response to stress did not result in a net increase in genera known to contain potentially pathogenic strains. Conclusion: The decrease in microbial diversity and the disassociation between population genetic structure of the hosts and their associated microbiome suggest that disturbance (i.e. stress) may play a significant role for the assembly of the natural microbiome. Such community shifts may in turn also feed back on the course of disease and the occurrence of mass mortality events in oyster populations.

Fatty acids and intact polar lipids of laminated microbial sediments from St. Peter Ording, German Wadden Sea

Hidden for the untrained eye through a thin layer of sand, laminated microbial sediments occur in supratidal beaches along the North Sea coast. The inhabiting microbial communities organize themselves in response to vertical gradients of light, oxygen or sulfur compounds. We performed a fine-scale investigation on the vertical zonation of the microbial communities using a lipid biomarker approach, and assessed the biogeochemical processes using a combination of microsensor measurements and a 13C-labeling experiment. Lipid biomarker fingerprinting showed the overarching importance of cyanobacteria and diatoms in these systems, and heterocyst glycolipids revealed the presence of diazotrophic cyanobacteria even in 9 to 20 mm depth. High abundance of ornithine lipids (OL) throughout the system may derive from sulfate reducing bacteria, while a characteristic OL profile between 5 and 8 mm may indicate presence of purple non-sulfur bacteria. The fate of 13C-labeled bicarbonate was followed by experimentally investigating the uptake into microbial lipids, revealing an overarching importance of cyanobacteria for carbon fixation. However, in deeper layers, uptake into purple sulfur bacteria was evident, and a close microbial coupling could be shown by uptake of label into lipids of sulfate reducing bacteria in the deepest layer. Microsensor measurements in sediment cores collected at a later time point revealed the same general pattern as the biomarker analysis and the labeling experiments. Oxygen and pH-microsensor profiles showed active photosynthesis in the top layer. The sulfide that diffuses from deeper down and decreases just below the layer of active oxygenic photosynthesis indicates the presence of sulfur bacteria, like anoxygenic phototrophs that use sulfide instead of water for photosynthesis.

El Estado de Bienestar : 1918-1955

Con el fin de conocer las últimas interpretaciones acerca de nuestro pasado regional, los videos de la serie "Mendoza, crónica de nuestra identidad", pretenden llevar adelante la tarea constante de construir y reconstruir una identidad que se mantenga abierta a los valores del pasado, pero también a la inevitable reformulación crítica de los mismos principios. La propuesta es generar un proceso de actualización y perfeccionamiento en el campo de la historia regional. En el documental EL ESTADO DE BIENESTAR: 1918-1955, se describen sus primeras manifestaciones en Mendoza, las reformas sociales de los gobiernos lencinistas, el peronismo y la ampliación del Estado, las producciones y manifestaciones culturales en una economía creciente y la otra cara de la abundancia: los reclamos sociales.

Presupuestos éticos de la visión de la economía en la obra periodística de Andrés Bello (1831-1843)

Consideración sobre la obra periodística de Andrés Bello, uno de los autores decimonónicos que asumieron los valores e ideas ilustradas y liberales, derivadas de los pensadores ingleses y franceses de comienzos del siglo XIX. Estas ideas aparecen en sus textos académicos y sobre todo en los periódicos en los que colaboró. Entre sus ideas económicas más importantes, que generaron “opinión pública", se destaca la valorización de la libre iniciativa, la propiedad privada y la búsqueda del aumento de la riqueza como estrategia para el progreso de los países. Se analiza este trasfondo social y económico porque se trata de ideas y perspectivas éticas donde convergen la moralidad, la política y el derecho, cuya importancia es destacable frente a un mundo globalizado.
