There is overwhelming evidence that riverine
nutrients drive both the production of
phytoplankton and the size of the hypoxic
zone on the inner shelf.
Response of phytoplankton in an alpine lake to inputs of dissolved organic matter through nutrient enrichment and trophic forcing
Response of phytoplankton trophic forcing
2014/4/2
Inputs of terrestrially derived dissolved organic matter (DOM) are increasing in alpine lakes due to multiple
drivers such as climate change, tree line advancement, and insect epidemics. A 21 d micro...
Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
Relative importance of trophic interactions and nutrient enrichment in seagrass ecosystems: A broad-scale field experiment in the Baltic–Skagerrak area
Relative importance trophic interactions nutrient enrichment in seagrass ecosystems A broad-scale field experiment the Baltic–Skagerrak area
2014/4/17
The interaction of eutrophication and predation in structuring seagrassZostera marinaL. ecosystems was assessed in a field experiment in three regions along an estuarine salinity gradient, from southe...
Rates of overgrowth by macroalgae and attack by sea anemones are greater for live coral than dead coral under conditions of nutrient enrichment
Rates of overgrowth macroalgae attack
2014/4/18
A mesocosm experiment was conducted to determine the effects of nutrient enrichment on competitive
interactions between a hard coral, a green alga, and a sea anemone. In the low-nutrient controls, ab...
Imbalanced coral growth between organic tissue and carbonate skeleton caused by nutrient enrichment
Imbalanced coral growth organic tissue carbonate skeleton nutrient enrichment

Effects of moderate nutrient enrichment (NO3- : <5 μmol L-1, PO43- : <0.3 μmol L-1) on two carbon (C) fixation rates (photosynthesis and calcification) of the zooxanthellate coral Acropora pulchra wer...
Contrasting response of stream detritivores to long-term nutrient enrichment
stream detritivores long-term nutrient enrichment
2014/5/13
We examined growth and production responses of two dominant stream detritivores (chironomids and Tallaperla
spp. stoneflies) at opposite ends of the ‘‘slow-fast’’ life-history continuum and wit...
Phytoplankton response to nutrient enrichment in an urbanized estuary: Apparent inhibition of primary production by overeutrophication
Phytoplankton response nutrient enrichment
2014/4/30
Phytoplankton response to nutrients was examined with a 26-yr database from the Delaware Estuary. Biomassnormalized primary production did not increase linearly with increasing nutrient concentrations...
Coupling of near-bottom seston and surface sediment composition: Changes with nutrient enrichment and implications for estuarine food supply and biogeochemical processing
near-bottom seston surface sediment composition Changes with nutrient enrichment estuarine food supply biogeochemical processing
2014/5/8
We compared near-bottom seston and surface sediment composition in Cape Cod estuaries receiving different N loads to determine whether eutrophic-driven changes in seston and sediment composition occur...
Evidence for nutrient enrichment of high-elevation lakes in the Sierra Nevada, California
nutrient enrichmen high-elevation lakes Sierra Nevada California
2014/5/21
Long-term measurements (1983-2001) of nutrients and seston in Emerald Lake (Sierra Nevada, California) have revealed ecologically significant patterns. Nitrate, both during spring runoff and during gr...
Beyond bulk properties: Responses of coastal summer plankton communities to nutrient enrichment in the northern Baltic Sea
Beyond bulk properties coastal summer plankton
2014/5/20
Enclosure experiments with all combinations of NH4
and PO4
treatments were carried out in the northern Baltic
coastal zone during the post–spring bloom growth season. Empirical models were used to ...
