Temporal responses of coastal hypoxia to nutrient loading and physical controls
Temporal responses coastal hypoxia nutrient loading physical controls
2010/1/21
The incidence and intensity of hypoxic waters in coastal aquatic ecosystems has been expanding in recent decades coincident with eutrophication of the coastal zone. Worldwide, there is strong interest...
A two-dimensional layer-averaged Bingham fluid numerical model has been used to explore the relative importance of yield stress, kinematic viscosity,bottom slope and initial failure height on the run-...
Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida
Physiological controls seawater uptake calcification benthic foraminifer Ammonia tepida
2010/1/21
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with ...
Plant physiological and environmental controls over the exchange of acetaldehyde between forest canopies and the atmosphere
physiological and environmental controls exchange forest canopies atmosphere
2010/1/18
We quantified fine scale sources and sinks of gas phase acetaldehyde in two forested ecosystems in the US. During the daytime, the upper canopy behaved as a net source while at lower heights, reduced ...
Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
Small scale controls greenhouse gas release N deposition rates
2010/1/15
In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environm...
Leaf area controls on energy partitioning of a temperate mountain grassland
Leaf area controls energy partitioning temperate mountain grassland
2010/1/15
Using a six year data set of eddy covariance flux measurements of sensible and latent heat, soil heat flux, net radiation, above-ground phytomass and meteorological driving forces energy partitioning ...
Environmental controls over methanol emission from leaves
Environmental controls methanol emission leaves
2010/1/15
Methanol is found throughout the troposphere, with average concentrations second only to methane among atmospheric hydrocarbons. Proposed global methanol budgets are highly uncertain, but all agree th...
Biotic stoichiometric controls on the deep ocean N:P ratio
Biotic stoichiometric controls deep ocean N:P ratio
2010/1/14
We re-examine what controls the deep ocean N:P ratio in the light of recent findings that the C:N:P stoichiometry of phytoplankton varies with growth rate, nutrient and light limitation, species and p...
Controls over N2O,NOx and CO2 fluxes in a calcareous mountain forest soil
Controls N2O NOx CO2 fluxes calcareous mountain forest soil
2010/1/13
We measured nitrogen oxides (N2O and NOx), dinitrogen (N2) and carbon dioxide (CO2) emissions from a spruce-fir-beech forest soil in the North Tyrolean limestone Alps in Austria. The site received 10....
Large-scale environmental controls on microbial biofilms in high-alpine streams
Large-scale environmental controls microbial biofilms high-alpine streams
2010/1/7
Glaciers are highly responsive to global warming and important agents of landscape heterogeneity. While it is well established that glacial ablation and snowmelt regulate stream discharge, linkage amo...
