Mitigating eutrophication and toxic cyanobacterial blooms in large lakes: The evolution of a dual nutrient (N and P) reduction paradigm
Cyanobacterial harmful algal blooms (CyanoHABs) are an increasingly common feature of large, eutrophic lakes. Non-N2-fixing CyanoHABs (e.g., Microcystis) appear to be proliferating relative to N2-fixing CyanoHABs...

Revisiting the total maximum daily load total phosphorus goal in Lake Okeechobee
In 2000, a total maximum daily load (TMDL) total phosphorus (TP) goal of 40 µg/L was established for Lake Okeechobee, Florida. The goal was selected to reduce the “imbalance to flora and fauna” caused by exces...

Open AccessHurricanes, El Niño and harmful algal blooms in two sub-tropical Florida estuaries: Direct and indirect impacts
Future increases in the intensity of hurricanes and El Niño periods predicted by climate change models have focused attention on their role in stimulating harmful algal blooms (HABs). A series of hurricanes th...

Dynamics of cyanobacteria blooms are linked to the hydrology of shallow Florida lakes and provide insight into possible impacts of climate change
Analysis of an 18-year dataset from seven shallow lakes in Florida provides evidence of hydrologic factors controlling dynamics of cyanobacteria blooms. Depth was the most important variable, and there was a s...

Article
Inter-lake comparisons indicate that fish predation, rather than high temperature, is the major driver of summer decline in Daphnia and other changes among cladoceran zooplankton in subtropical Florida lakes
The mid-summer disappearance of Daphnia and the small size of cladocerans in subtropical lakes have been explained as phenomena caused by high water temperature. Recent experimental and observational studies sugg...

Predicting Ecological Responses of the Florida Everglades to Possible Future Climate Scenarios: Introduction
Florida’s Everglades stretch from the headwaters of the Kissimmee River near Orlando to Florida Bay. Under natural conditions in this flat landscape, water flowed slowly downstream as broad, shallow sheet flow...

Ecological Responses of a Large Shallow Lake (Okeechobee, Florida) to Climate Change and Potential Future Hydrologic Regimes
We considered how Lake Okeechobee, a large shallow lake in Florida, USA, might respond to altered hydrology associated with climate change scenarios in 2060. Water budgets and stage hydrographs were provided ...

Temperature effects on body size of freshwater crustacean zooplankton from Greenland to the tropics
The body size of zooplankton has many substantive effects on the function of aquatic food webs. A variety of factors may affect size, and earlier studies indicate that water temperature may be a particularly i...

Chapter
Lake Eutrophication and Plankton Food Webs
The plankton food web comprises microscopic organisms that transport carbon and energy from producers to consumers in the water column of aquatic ecosystems. In lakes, the food web includes bacteria, phytoplan...

Extreme weather events influence the phytoplankton community structure in a large lowland subtropical lake (Lake Okeechobee, Florida, USA)
We demonstrate a major ecological change in a large lake ecosystem in response to a series of extreme weather events. Phytoplankton community dynamics in subtropical Lake Okeechobee are described from 2000 thr...

Zooplankton to phytoplankton biomass ratios in shallow Florida lakes: an evaluation of seasonality and hypotheses about factors controlling variability
We examined crustacean zooplankton data (excluding nauplii) from 15 shallow lakes in south and central Florida, spanning a range of sizes and Chlorophyll-a concentrations. Each dataset was comprised of monthly sa...

Composition, size, and biomass of zooplankton in large productive Florida lakes
Crustacean zooplankton data were compiled from long-term observational studies at seven large shallow Florida lakes, to determine whether there are general characteristics in regard to species composition, bod...

Zooplankton–phytoplankton relationships in shallow subtropical versus temperate lakes Apopka (Florida, USA) and Trasimeno (Umbria, Italy)
This study compares and contrasts the dynamics of phytoplankton, zooplankton, and nutrients in two of the largest shallow lakes in the USA (Lake Apopka, Florida) and Europe (Lago Trasimeno, Umbria, Italy) and ...

Zooplankton response to extreme drought in a large subtropical lake
Plankton data from 1997 to 2005 were used to examine impacts of a managed draw-down, subsequent drought and resulting historic low water levels (during 2000 and 2001) on the zooplankton of Lake Okeechobee, Flo...

Phosphorus dynamics at multiple time scales in the pelagic zone of a large shallow lake in Florida, USA
Phosphorus (P) dynamics in large shallow lakes are greatly influenced by physical processes such as wind-driven sediment resuspension, at times scales from hours to years. Results from long-term (30 year) rese...
