Disturbance Increases Microbial Community Diversity and Production in Marine Sediments
Disturbance strongly impacts patterns of community diversity, yet the shape of the diversity-disturbance relationship remains a matter of debate. The topic has been of interest in theoretical ecology for decades as it has practical implications for the understanding of ecosystem services in nature. One of these processes is the remineralization of organic matter by microorganisms in coastal mar...

متن کاملMicrobial community composition of anoxic marine sediments in the Bay of Cádiz (Spain).
The composition of the microbial community inhabiting the anoxic coastal sediments of the Bay of Cádiz (southern Spain) was investigated using a molecular approach consisting of PCR cloning and denaturing gradient gel electrophoresis (DGGE), based on 16S rRNA sequences. The total cell count was 1-5 × 10⁸ cells/g sediment and, as determined by catalyzed reporter deposition-fluorescent in situ hy...
متن کاملMarine Subsurface Microbial Community Shifts Across a Hydrothermal Gradient in Okinawa Trough Sediments
Sediments within the Okinawa back-arc basin overlay a subsurface hydrothermal network, creating intense temperature gradients with sediment depth and potential limits for microbial diversity. We investigated taxonomic changes across 45 m of recovered core with a temperature gradient of 3°C/m from the dynamic Iheya North Hydrothermal System. The interval transitions sharply from low-temperature ...
متن کاملQuantitative molecular analysis of the microbial community in marine arctic sediments (Svalbard).
Fluorescence in situ hybridization (FISH) and rRNA slot blot hybridization with 16S rRNA-targeted oligonucleotide probes were used to investigate the phylogenetic composition of a marine Arctic sediment (Svalbard). 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 (4',6'-diamidino-2-phenylindole) cell counts...
