N:P ratios, light limitation, and cyanobacterial dominance in a subtropical lake impacted by non-point source nutrient pollution
TLDR
In the near-shore regions of this shallow lake, low N:P ratios potentially favor blooms of N2-fixing cyanobacteria, but their occurrence in the pelagic zone is restricted by low irradiance and lack of stable stratification.About:

Climate change: links to global expansion of harmful cyanobacteria.

TL;DR: Overall, stricter nutrient management will likely be the most feasible and practical approach to long-term CyanoHAB control in a warmer, stormier and more extreme world.
Journal ArticleDOI
The dilemma of controlling cultural eutrophication of lakes.
TL;DR: It is concluded that long-term, whole-ecosystem experiments and case histories of lake recovery provide the only reliable evidence for policies to reduce eutrophication and the case for phosphorus control has been strengthened.

Harmful Algal Blooms

TL;DR: While HABs are as diverse as the water bodies they impact, this chapter focuses on some specific examples of known HAB taxa that affect inland waters in North America and highlight some of the important strategies used by these species to enable their excessive growth.

Management of Fluid Mud in Estuaries, Bays, and Lakes. I: Present State of Understanding on Character and Behavior
William H. McAnally,Carl T. Friedrichs,Douglas Hamilton,Earl J. Hayter,Parmeshwar L. Shrestha,Hugo Rodriguez,Alexandru Sheremet,Allen M. Teeter +7 more
TL;DR: Fluid mud is a high concentration aqueous suspension of fine-grained sediment in which settling is substantially hindered as discussed by the authors, and constitutes a significant management problem in rivers, lakes, estuaries, and shelves by impeding navigation, reducing water quality and damaging equipment.
Journal ArticleDOI
Nitrogen fixation may not balance the nitrogen pool in lakes over timescales relevant to eutrophication management
TL;DR: The authors explored multi-year linear trends in nutrient concentrations, nitrogen (N):phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake 227 of the Experimental Lakes Area, Canada.

Book
Resource competition and community structure
TL;DR: This book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities and explores such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.
Book
The ecology of freshwater phytoplankton
TL;DR: The phytoplankton-like structure of lakes and rivers has an important role in determining the food web structure of animals and the environment and its role in promoting growth and survival in animals and humans.
Journal ArticleDOI
Eutrophication: impacts of excess nutrient inputs on freshwater, marine, and terrestrial ecosystems
TL;DR: Two brief case studies demonstrate that nutrient loading restriction is the essential cornerstone of aquatic eutrophication control, and results of a preliminary statistical analysis are presented consistent with the hypothesis that anthropogenic emissions of oxidized nitrogen could be influencing atmospheric levels of carbon dioxide via nitrogen stimulation of global primary production.
Journal ArticleDOI
The inverted microscope method of estimating algal numbers and the statistical basis of estimations by counting
TL;DR: If the organisms are randomly distributed, a single count is sufficient to obtain an estimate of their abundance and confidence limits for this estimate, even if pipetting, dilution or concentration are involved.
