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...
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...
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...
Primary production in two shallow lakes with contrasting plant form dominance: A paradox of enrichment?
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...
Historic low-level phosphorus enrichment in the Great Lakes inferred from biogenic silica accumulation in sediments
Historic low-level phosphorus enrichment Great Lakes inferred
2014/4/30
Sedimentary biogenic silica (BSi) accumulation was used in conjunction with a hypothetical model of BSi
accumulation to show that BSi is a sensitive proxy for low-level phosphorus enrichment in the G...
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...
Enrichment of amino acids in the sea surface microlayer at coastal and open ocean sites in the North Atlantic Ocean
amino acids sea surface microlayer
2014/5/19
We investigated how regional differences in environmental parameters influenced enrichment of amino acids in
the sea surface microlayer relative to underlying bulk seawater. Concentrations and ...
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 ...
