Microbial Community Dynamics Of A Microcystis Bloom, Helena Pound
Microbial Community Dynamics Of A Microcystis Bloom, Helena Pound
Doctoral Dissertations
Harmful algal bloom events are notoriously associated with massive economic and environmental consequences, causing wildlife and human health risks. As these blooms increase in occurrence, duration, and severity around the world, it is essential to understand conditions leading to bloom formation and why they persist. Abiotic factors such as nutrients are commonly considered in bloom dynamics, but biotic interactions with co-occurring microbial species and viruses must also be taken into account. Harmful algal blooms dominated by the cyanobacterial genus Microcystis occur in bodies of water around the world and provide an ideal system in which to study top-down controls on …

Urea As A Nitrogen Source For Microcystis Aeruginosa, Bernard Shafer Belisle
Masters Theses
Over the last decade, Lake Erie has experienced annual harmful algal blooms events dominated by the toxic cyanobacterium Microcystis aeruginosa. It is still unclear what causes Microcystis blooms to occur, but there is broad agreement that eutrophication of freshwater systems from anthropogenic sources (urban, industrial, etc.), has led to their proliferation. In particular, the organic compound urea has been implicated as an important source of anthropogenic nitrogen, due to its increased use in agricultural practices. Currently, urea constitutes more than 50% of the nitrogen used for agricultural fertilizer globally, and its usage has increased more than a 100-fold over …
