Microbial control over carbon cycling in soil
A major thrust of terrestrial microbial ecology is focused on understanding when and how the composition of the microbial community affects the functioning of biogeochemical processes at the ecosystem scale (meters-to-kilometers and days-to-years). While research has demonstrated these linkages for physiologically and phylogenetically "narrow" processes such as trace gas emissions and nitrifica...
متن کاملSubduction zone rheology
Rheological flow laws can be obtained from studies using multi-anvil high-pressure systems with synchrotron-based piezometers and strain metrics. The high flux X-ray source provides minute-scale time resolution with accurate measurement of diffraction patterns and direct sample images. Measurements of length changes with an accuracy of one part in 104 are being developed and will provide a new ...
متن کاملEarthquake hazards on the cascadia subduction zone.
Large subduction earthquakes on the Cascadia subduction zone pose a potential seismic hazard. Very young oceanic lithosphere (10 million years old) is being subducted beneath North America at a rate of approximately 4 centimeters per year. The Cascadia subduction zone shares many characteristics with subduction zones in southern Chile, southwestern Japan, and Colombia, where comparably young oc...
متن کاملMicrobial processes regulating carbon cycling in subtropical wetlands
Wetlands host complex microbial communities including bacteria, fungi, protozoa and viruses. The size and diversity of microbial communities are related directly to the quality and quantity of the resources (i.e., nutrients, energy sources) available in the system. Microbial biomass and activity is highest in habitats where these resources are concentrated, including periphyton mats, plant detr...
متن کاملModeling soil microbial dynamics in carbon and nitrogen cycling
Goal To determine the relative importance of different mechanisms that influence carbon loss from soil under variable soil-moisture conditions. The soil contains more carbon than the atmosphere and plants combined (Scurlock and Hall 1998). This carbon is important for maintaining soil fertility, controlling erosion, and the long-term storage of carbon that could be released into the atmosphere....
