The Role of Eutrophication in the Global Proliferation of Harmful Algal Blooms
Eutrophication Global Proliferation Harmful Algal Blooms
2015/7/27
Cultural eutrophication, the pollution of coastal waters by nutrients, is a result of population growth, food production (agriculture, animal operations and aquaculture), and energy production and con...
Regional-scale effects of eutrophication on ecosystem structure and services of seagrass beds
Regional-scale effects eutrophication ecosystem structure services of seagrass beds
2014/4/3
Using large-scale field surveys across 12 estuaries in two provinces in Atlantic Canada, we analyzed changes in phytoplankton and benthic macroalgal communities as well as the canopy structure of eelg...
Nitrogen fixation may not balance the nitrogen pool in lakes over timescales relevant to eutrophication management
Nitrogen fixation may not balance nitrogen pool in lakes over timescales relevant eutrophication management
2014/4/17
We explored multiyear linear trends in nutrient concentrations, nitrogen (N) : phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake ...
Evidence of warming effects on phytoplankton productivity rates and their dependence on eutrophication status
warming effects phytoplankton productivity rates eutrophication status
2014/4/17
Using 31-yr data from measurements in a lake that has experienced change in eutrophication status, I showed that the effects of global warming on chlorophyll a (Chl a)–normalized maximum rates of phot...
The effect of long-term spatiotemporal variations in urbanization-induced eutrophication on a benthic ecosystem, Osaka Bay, Japan
spatiotemporal variations urbanization-induced eutrophication a benthic ecosystem Osaka Bay Japan
2014/4/22
Detailed spatiotemporal patterns of the influence of urbanization-induced eutrophication on a metazoan benthic community in Osaka Bay were determined using sediment cores and fossil ostracode assembla...
Summer algal blooms in shallow estuaries: Definition, mechanisms, and link to eutrophication
Summer algal blooms in shallow estuaries: Definition, mechanisms, and link to eutrophication
2014/4/22
We propose a definition for identification of blooms and use this definition to investigate the underlying mechanisms of summer blooms and their link to nutrient enrichment. Blooms were defined as chl...
Eutrophication of ancient Lake Ohrid: Global warming amplifies detrimental effects of increased nutrient inputs
Eutrophication of ancient Lake Ohrid Global warming amplifies detrimental effects increased nutrient inputs
2014/4/22
Lake Ohrid in southeastern Europe is one of the few ancient, long-lived lakes of the world, and contains more than 200 endemic species. On the basis of integrated monitoring of internal and external n...

Recent advances in the understanding and management of eutrophication
Recent advances eutrophication
2014/4/30
Major advances in the scientific understanding and management of eutrophication have been made since the late
1960s. The control of point sources of phosphorus reduced algal blooms in many lake...
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...
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...
