Characterization of The Persistent Cyanobacterial Bloom, Planktothrix in Sandusky Bay, Lake Erie

OHSU-TD-1512
ABSTRACT:

Planktothrix sp. is less studied than other bloom-forming cyanobacteria. The aim of this study was to determine characteristics of the Planktothrix bloom in Sandusky Bay. Using the 2013 Sandusky Bay metagenome and 2014 summer samples, it was found that the bloom in Sandusky Bay has limited diversity and is continuously dominated by Planktothrix. Nutrient profiles of the Bay suggest nitrogen limitation throughout the bloom season. Physical parameters recorded in Sandusky Bay are suboptimal for many known bloom-forming cyanobacteria. Given this information, it is not yet understood how Planktothrix survives and dominates Sandusky Bay. Future work will look further at community members playing a role in the nitrogen cycle in the Bay. Additionally, the succession of genotypes will be determined over time as the environmental parameters will be monitored over a longer period of time to determine how survival of Planktothrix is supported.

National Oceanic and Atmospheric Administration Harmful Algal Blooms Forecast 2014 Webinar

OHSU-CAST-1530

Recording of NOAA’s 2014 harmful algal blooms forecast, issued from Stone Lab.

ABSTRACT:

NOAA and its research partners predict that western Lake Erie will have a significant bloom of cyanobacteria, a toxic blue-green algae, during the 2014 bloom season in late summer. However, the predicted bloom is expected to be smaller than last year’s intense bloom, and considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake’s western basin and are classified by an estimate of both its concentration and how far it spreads.

Climate Change and Harmful Algal Blooms in Maumee Bay Webinar

OHSU-CAST-1527

This webinar covers the potential for future algal blooms in Lake Erie’s western basin.

ABSTRACT:

Harmful algal blooms (HABs) are a global problem and have reemerged as a concern in Lake Erie during the last decade. While some have hypothesized HABs in Lake Erie will become more frequent and larger, there are few studies linking predicted climate and watershed models to examine this issue. This talk will describe the methods and results of an ongoing project that links climate models, watershed models and HABs models to predict the frequency and magnitude of HABs through 2099.
This webinar will describe:

Predicted climate for the Maumee Basin through 2099
How climate change is likely to affect river discharge and harmful algal blooms in western Lake Erie
Modeling tools that can help people understand and manage the impacts of extreme weather events and climate change

Organic and inorganic nitrogen utilization by nitrogen-stressed cyanobacteria during bloom conditions

OHSU-RS-1502

Manuscript on nitrogen utilization by cyanobacteria

ABSTRACT:

Cyanobacterial blooms often occur in lakes that have high phosphorus (P) and low nitrogen (N) concentrations, and the growth rate of the blooms is often constrained by N. For these reasons, many researchers have suggested that regulation of both P and N is required to control eutrophication. However, because N occurs in many bioavailable forms, regulation of a particular form may be beneficial rather than regulation of all N forms. To address how N-stressed cyanobacteria respond to various N inputs, N enrichment experiments (nitrate, ammonium, urea, and alanine) were performed during N-limited cyanobacterial blooms in Maumee and Sandusky Bays of Lake Erie and in Grand Lake St. Marys (GLSM). Bioavailable N (nitrate, urea, and ammonium) concentrationswere also determined. Microcystis aeruginosa dominated the Maumee Bay bloom, where the highest growth rates were in response to ammonium additions, and lowest growth rates were in response to nitrate. Urea and the amino acid alanine resulted in intermediate growth rates. Planktothrix agardhii dominated the Sandusky Bay and GLSM blooms, where nitrate, ammonium, and urea addition resulted in similar growth rates. Additions of alanine did not stimulate growth of the Planktothrix blooms. Incubations using stable isotope 15N showed the cyanobacteria had a preference for ammonium, but the other forms were also assimilated in the presence of ammonium. These results show that cyanobacterial blooms will assimilate multiple forms of N to support growth. Thus, if lake managers do decide that N abatement is necessary, then all forms of bioavailable N need to be constrained.

Climate Change and Harmful Algal Blooms in Lake Erie Webinar

OHSU-CAST-1509

This 2013 climate webinar provides information about historical climate and potential future impacts of climate change in the Lake Erie basin.

ABSTRACT:

Harmful algal blooms continue to be a problem for the Lake Erie ecosystem and lakeshore communities, and predicted climate change impacts like increased heavy precipitation and higher temperatures have the potential to worsen these problems in the future. Focusing on Lake Erie, this webinar will provide information about historical climate and potential future impacts of climate change in the Lake Erie basin; how climate change could impact Lake Erie nutrient levels that drive harmful algal blooms; the potential effects of reduced lake ice and higher temperatures on algal blooms’ length and size. Speakers: Dr. Rick Stumpf of NOAA and Molly Woloszyn of Midwestern Regional Climate Center
