Study of Belize Barrier Reef Shows Nitrogen Enrichment from Land-based Sources Doubled in Four Decades：What’s killing coral reefs in Florida is also killing them in Belize
coral reef nitrogen concentration algal blooms ecological system
2021/8/5
Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly ...
A New Database to Explore the Findings from Large-Scale Ocean Iron Enrichment Experiments
New Database Large-Scale Ocean Iron Enrichment Experiments
2015/7/15
Some of the largest scientific manipulation experiments conducted on our planet have enriched broad swaths of the surface ocean with iron. Surface ocean signatures of these iron enrichment experiments...
Enrichment of particulate phosphorus in a sea-surface microlayer over the Eastern Equatorial Pacific Ocean
sea-surface microlayer biogeochemical enrichment particulate phosphorus high-nutrient low-chlorophyll ocean
2017/4/11
The significant enrichment of chemical composition associated with enhanced bioactivities and an increased number
of bio-particles in the sea-surface microlayer (SML) were observed in the high-nutrie...
Phosphorus enrichment and carbon depletion contribute to high Microcystis biomass and microcystin concentrations in Ugandan lakes
Phosphorus enrichment carbon depletion contribute
2014/4/2
We investigated the factors influencing cyanobacterial biomass and microcystin (MC) concentrations in several
Ugandan lakes from September 2008 to February 2009. We characterized thermal structure, l...
Nitrogen enrichment increases net silica accumulation in a temperate salt marsh
Nitrogen enrichment increases net silica accumulation a temperate salt marsh
2014/4/2
Two New England salt marshes exposed to different N availability were assessed seasonally for 1 yr, creating the first complete salt marsh Si budgets. Triplicate seasonal measurements were collected f...
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...
Isotope enrichment in mangrove forests separates microphytobenthos anddetritus as carbon sources for animals
Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...
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...

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...

Primary production contrasting plant
2014/5/5
We estimated total lake plant biomass and primary net production in two shallow Swedish lakes that differ in
nutrient loading and plant form dominance. In clearwater Lake Krankesjo¨n (10 mg chlorophy...
