2014/5/19
We have determined the seasonal (July 2001–July 2002) and vertical variability in the photosynthetic production
of dissolved organic carbon (DOCp) and particulate organic carbon (POCp) in a coastal u...
Biodiversity and ecosystem functioning: A complex adaptive systems approach

2014/5/16
Environmental factors regulate biodiversity through species sorting processes. Species distributions in communities affect ecosystem processes and environmental factors. These dynamics are determined ...

We propose a new operational definition for summer phytoplankton blooms based on station-specific chlorophyll
a distributions. This definition has been applied to a large monitoring...

Net ecosystem production was examined in the Mandovi and Zuari estuaries (southwestern India) and the adjoining coastal waters for a period of 1 yr (January to December 1998). The study period encompa...
Ecosystem metabolism controls nitrogen uptake in streams in Grand Teton National Park, Wyoming
Ecosystem metabolism controls nitrogen uptake streams Grand Teton National Park Wyoming

2014/5/20
Streams and rivers regulate nitrogen transport (N) to downstream ecosystems. Rates of N uptake can be high in streams, but controls on the variation in uptake rates of N among streams are not known. W...
Annual primary production: Patterns and mechanisms of change in a nutrient-rich tidal ecosystem
Annual primary production Patterns and mechanisms of change nutrient-rich tidal ecosystem

2014/5/27
Although nutrient supply often underlies long-term changes in aquatic primary production, other regulatory processes can be important. The Sacramento-San Joaquin River Delta, a complex of tidal waterw...
Net ecosystem production of dissolved organic carbon in a coastal upwelling system: The Ría de Vigo, Iberian margin of the North Atlantic
Net ecosystem production dissolved organic carbon a coastal upwelling system The Ría de Vigo Iberian margin North Atlantic

2014/5/30
Net ecosystem production (NEP) rates of dissolved organic carbon (DOC) are estimated in a coastal upwelling system. The study site is a large coastal inlet (2.76 km3) in the northern boundary (42-43°N...
Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem
Phosphorus inactivation aluminum in the water column sediments in-lake phosphorus availability acidified watershed-lake ecosystem

2014/6/17
Acid precipitation has been shown to reduce phosphorus (P) outputs from terrestrial sources. We present field evidence that the in-lake P cycle may also be disrupted in atmospherically acidified water...
