Aging of allochthonous organic carbon regulates bacterial production in unproductive boreal lakes
allochthonous organic carbo production in unproductive
2014/4/18
We calculated average aquatic dissolved organic carbon (DOC) age (the time span from soil discharge to
observation) in water from the inlets and outlets of two unproductive Swedish lakes at different...
Increased supply of ambient nitrogen has minimal effect on salt marsh bacterial production
Increased supply of ambient nitrogen salt marsh
2014/4/18
We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...
Enhanced viral production and infection of bacterioplankton during an iron-induced phytoplankton bloom in the Southern Ocean
Enhanced viral production iron-induced phytoplankton
2014/4/18
We followed the viral response to Fe-enrichment over 3 weeks during the second iron-enrichment experiment
(EisenEx) in the Southern Ocean. Although viral abundance increased in a rather constant way ...
Assessing ecological responses to catastrophic amphibian declines: Patterns of macroinvertebrate production and food web structure in upland Panamanian streams
Assessing ecological responses catastrophic amphibian declines
2014/4/17
As part of the Tropical Amphibian Declines in Streams (TADS) project, we estimated macroinvertebrate
production and constructed quantitative food webs for four headwater stream reaches in the Panaman...
Seasonal dynamics of new production from Trichodesmium N2 fixation and nitrate uptake in the upstream Kuroshio and South China Sea basin
Seasonal dynamics Trichodesmium N2 fixation
2014/4/21
The seasonal dynamics of primary production in the upstream Kuroshio was studied to understand why
pelagic fish are relatively populous in this oligotrophic tropical ocean region. The relative import...
Net community production in the deep euphotic zone of the subtropical North Pacific gyre from glider surveys
the subtropical North Pacific gyre Net community production
2014/4/18
Seagliders, deployed through most of 2005 in the subtropical North Pacific gyre, made measurements of
temperature, salinity, and dissolved oxygen to quantify net community production (NCP) at Station...
Determining net dissolved organic carbon production in the hydrographically complex western Arctic Ocean
Determining net dissolved organic hydrographically complex western Arctic Ocean
2014/4/22
Each spring and summer, the Chukchi Sea in the western Arctic Ocean experiences a short but intense
phytoplankton bloom that is controlled by sea ice cover, nutrient availability, and river runoff. D...
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...
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...

sources and ages of organic matter (OM) assimilated by bacteria in the Huds...
Nonrandom sexual reproduction and diapausing egg production in a Daphnia hybrid species complex
Nonrandom sexual reproduction
2014/5/16
Sexual reproduction in Daphnia results in the production of diapausing eggs, which are enclosed in a structure
called ephippium. Ephippia, accumulated by sedimentation, can be preserved for decades a...
Millennial-scale relationships of diatom species richness and production in two prairie lakes
2014/5/16
Insight into the causes and consequences of changes in aquatic biodiversity requires an improved understanding
of the nature of the relationships between species richness and ecosystem function over ...

Bottom-up controls on bacterial production in tropical lowland rivers
bacterial production tropical lowland rivers
2014/5/21
The importance of organic carbon and inorganic nutrients in controlling bacterial production was investigated in
two tropical lowland rivers draining undisturbed forested catchments. Glucose (C), amm...
