Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets
Estimating Zooplankton Biomass Water Column Near Endeavour Segment Juan de Fuca Ridge Acoustic Backscatter Concurrently Towed Nets
2015/7/14
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate...
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...
Effects of environmental conditions on the seasonal distribution of phytoplankton biomass in the North Sea
environmental conditions the seasonal distribution phytoplankton biomass in the North Sea
2014/4/18
We study the spatial and seasonal variability of phytoplankton biomass (as phytoplankton color) in relation to the environmental conditions in the North Sea using data from the Continuous Plankton Rec...
Dreissenid mussels (Dreissena polymorphaandDreissena bugensis) reduce microzooplankton and macrozooplankton biomass in thermally stratified lakes
Dreissenid mussels reduce microzooplankton macrozooplankton biomass thermally stratified lakes
2014/4/16
We conducted a survey of 50 thermally stratified lakes with similar nutrient concentrations and morphometries in Michigan to examine the direct and indirect effects of dreissenid mussels on the biomas...
Why are diverse relationships observed between phytoplankton biomass and transport time?
diverse relationships observed ytoplankton
2014/4/17
Transport time scales such as flushing time and residence time are often used to explain variability in
phytoplankton biomass. In many cases, empirical data are consistent with a positive phytoplankt...

Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
13 C dynamics in benthic algae: Effects of light, phosphorus, and biomass development
13 C dynamics benthic algae light phosphorus biomass
2014/4/18
We performed three experiments in indoor streams and one experiment in a natural stream to investigate the effects of growth factors on d13 C levels in benthic microalgae. In the indoor streams, algae...

Growth rate versus biomass accumulation: Different roles of food quality and quantity for consumers
Growth rate versus biomass accumulation food quality
2014/4/22
Population growth and biomass accumulation of Daphnia magna was studied in a two-stage continuousculture system with light- and phosphorus-limited green algae (Selenastrum capricornutum) as food sourc...
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected to nutrient levels
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected nutrient levels
2014/4/23
During the 1980s, a rapid increase in the Phytoplankton Colour Index (PCI), a semiquantitative visual estimate of algal biomass, was observed in the North Sea as part of a regionwide regime shift. Two...
Top-down and bottom-up controls on periphyton biomass and productivity in Lake Tanganyika
Top-down and bottom-up controls periphyton biomass and productivity Lake Tanganyika
2014/5/4
We studied the effects of nutrient availability and grazers on periphyton in the littoral zone of Lake Tanganyika. Using a combination of dissolved nutrient ratios, nutrient diffusing substrates, and ...
Long-term temporal and spatial trends in phytoplankton biomass and class-level taxonomic composition in the hydrologically variable Neuse-Pamlico estuarine continuum, North Carolina, U.S.A.
Long-term temporal spatial trends phytoplankton biomass class-level taxonomic composition hydrologically variable Neuse-Pamlico estuarine continuum North Carolina U.S.A.
2014/5/4
Phytoplankton diagnostic photopigments in near-surface waters (~0.5 m) were identified and quantified by high-performance liquid chromatography beginning in April 1994 in the Neuse River Estuary and i...
Light supply, plankton biomass, and seston stoichiometry in a gradient of lake mixing depths
Light supply plankton biomass seston stoichiometry a gradient of lake mixing depths
2014/5/4
We derive from a dynamic model that light availability, phytoplankton density, and the carbon : nutrient ratio of phytoplankton biomass should all be negatively related to mixed surface layer depth, w...
