Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance a...
A new study by National Science Foundation-funded researchers at the Woods Hole Oceanographic Institution and their colleagues found that freshwater runoff from rivers and continental s...
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of micro...
We examined the separate and interactive effects of light, nutrients, and zooplanktivorous fish on phytoplankton nutrient stoichiometry, taxonomic richness, community composition, and the association...
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
Comment: Temperature, nutrients, and the size-scaling of phytoplankton growth in the sea。
To assess the significance of nutrient interactions on animal performance, life-history experiments were conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
Considerable drawdown of total dissolved inorganic carbon (CT) and oversaturation of oxygen (O2 ) within a cold (,15uC) oligotrophic eddy in the extratropical North Atlantic Ocean (46uN, 20.5uW) ind...
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separateand combined effec...
We measured historical changes in sedimentary δ15N and fossil pigments in four lakes with anadromous semelparous salmon and two reference lakes to quantify the degree to which the flux of marine-deriv...
We used high-resolution paleoecological records of environmental change to study the rate and magnitude of eutrophication over the last century in two contrasting coastal ecosystems. A multiproxy app...
We used a decadal data set, with weekly to biweekly sampling in April–October and monthly sampling in November– March, to characterize climatic (hurricane-level storms, a sustained 3-yr drought) and ...
We investigated long-term trends (1965–2002) in dissolved inorganic nutrients in the tidal part of the Scheldt estuary (Belgium, The Netherlands). Annually averaged concentrations of dissolved silica...
