Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood
Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood
Honors Projects
Global lakes are experiencing an increase in toxic algal blooms that can be damaging to the environment. These blooms are caused by cyanobacteria, specifically a species called Planktothrix. Skinn Lake, in Ohio, is a location of a cyanobacterial bloom that is mainly populated by Planktothrix rubescens. This lake was further examined to identify the major toxin-producing bacteria and identify environmental microbes surrounding the bloom. When the data was examined it was found that the microbiomes of the lake greatly differed between the winter (bloom) months and the summer (non-bloom) months. This difference can be viewed within the nutrient analysis from …

Eutrophication, a process that occurs due to excessive accumulation of nutrients such as nitrogen and phosphorous is primarily from anthropogenic nitrogen and natural occurrences. This phenomenon causes cyanobacterial overgrowth which can potentially lead to toxic algal blooms that affect public drinking water sources and recreational usage. An immediate need to detect bloom forming cyanobacteria in freshwater bodies early hand is critical to implement prevention strategies. These microorganisms contain phycobiliproteins such as phycoerytrhin, and allophycocyanin as part of the phycobillisome that allow autofluorescence. In this study, 36 freshwater bodies from 14 New Jersey counties were collected and processed for flow cytometric …

Microcystis aeruginosa is among the most common harmful algal-blooming species in the world. Potent microcystins released by M. aeruginosa have been linked to liver failure and death in aquatic mammals, like the endangered California sea otter, and provide a serious public health risk to humans. Once characterized as a freshwater problem, M. aeruginosa is expanding on a global scale, making persistent returns in freshwater, brackish, and coastal marine ecosystems. Though commonly observed dominating aquatic ecosystems in low N:P atomic ratios less than 44:1, the reliability of N:P ratios as a tool for managing and predicting M. aeruginosa blooms is explored …
