Cultural eutrophication in the Choptank and Patuxent estuaries of Chesapeake Bay
Cultural eutrophication Choptank Patuxent estuaries
2014/4/30
The Choptank and Patuxent tributaries of Chesapeake Bay have become eutrophic over the last 50–100 years.
Systematic monitoring of nutrient inputs began in ;1970, and there have been 2–5-fold increas...
Periphyton responses to eutrophication in the Florida Everglades: Cross-system patterns of structural and compositional change
Periphyton Florida Everglades Cross-system patterns
2014/4/30
We examined periphyton along transects in five Everglades marshes and related compositional and functional
aspects to phosphorus (P) gradients caused by enriched inflows. Results were com...
Top-down control from the bottom: Regulation of eutrophication in a large river by benthic grazing
Regulation of eutrophication benthic grazing
2014/4/30
We use a 15-yr record from a 100-km stretch of the tidal, freshwater Hudson River to examine the controls of
phytoplankton biomass. Across years, seasonal mean chlorophyll a (Chl a) and maximum Chl a...
Many natural streams are net heterotrophic, so I propose that trophic state be divided into autotrophic and
heterotrophic state. This division allows consideration of the influence of external ...
Large submarine groundwater discharge and benthic eutrophication in Bangdu Bay on volcanic Jeju Island, Korea
Large submarine groundwater discharge benthic eutrophication Bangdu Bay volcanic Jeju Island Korea
2014/5/13
We estimated the submarine discharge of groundwater (SGD) and associated nutrients into the semienclosed Bangdu Bay on a volcanic island, Jeju, Korea, by analyzing 222Rn, Ra isotopes (224Ra and 226Ra)...
The effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers
The effects of cultural eutrophication coupling pelagic primary producers benthic consumers
2014/5/13
We investigated the effects of cultural eutrophication on the coupling between pelagic primary producers and benthic consumers in Lake Tahoe. Spatial and temporal changes in zoobenthos energetics were...
From Greenland to green lakes: Cultural eutrophication and the loss of benthic pathways in lakes
green lakes Cultural eutrophication
2014/5/21
Benthic community responses to lake eutrophication are poorly understood relative to pelagic responses. We
compared phytoplankton and periphyton productivity along a eutrophication gradient in Greenl...
Sediment geochemical records of eutrophication in the mesohaline Chesapeake Bay
Sediment geochemical records eutrophication mesohaline Chesapeake Bay
2014/5/27
An organic geochemical analysis of sediments in three cores from the mesohaline Chesapeake Bay was carried out to reconstruct the progression of eutrophication and anoxia/hypoxia over the past five ce...
Sedimentological evidence of an increase in Pseudo-nitzschia (Bacillariophyceae) abundance in response to coastal eutrophication
SedimentolParsons, Michael L., Quay Dortch, R. Eugene Turnerogical evidence an increase Pseudo-nitzschia (Bacillariophyceae) abundance in response to coastal eutrophication
2014/5/26
Pseudo-nitzschia H. Peragallo, a marine planktonic diatom genus containing some species capable of producing the neurotoxin domoic acid, is often documented in extremely high concentrations in the nor...
Virus-like particle distribution and abundance in sediments and overlying waters along eutrophication gradients in two subtropical estuaries
Virus-like particle distribution abundance in sediments overlying waters along eutrophication gradients two subtropical estuaries
2014/6/10
Viruses are recognized as ubiquitous components of marine ecosystems; however, there has been limited study of viral abundance and its ecological role in sediments. Viral abundance was determined in b...
A review on the Control of Eutrophication in Deep and Shallow Lakes
Deep lake shallow lake phosphorus biomanipulation fish macrophyte
2010/4/1
There has been a much debate about the relative importance of the determination of phytoplankton crops by nutrients (bottom-up control) or by zooplankton grazing (top-down control). Wide acceptance of...
