Harmful algal blooms and eutrophication: Nutrient sources, composition, and consequences
Although algal blooms, including those considered toxic or harmful, can be natural phenomena, the nature of the global problem of harmful algal blooms (HABs) has expanded both in extent and its
Eutrophication of Chesapeake Bay: historical trends and ecological interactions
This review provides an integrated synthesis with timelines and evaluations of ecological responses to eutrophi- cation in Chesapeake Bay, the largest estuary in the USA. Analyses of dated sediment
Eutrophication and Harmful Algal Blooms: A Scientific Consensus.
In January 2003, the US Environmental Protection Agency sponsored a "roundtable discussion" to develop a consensus on the relationship between eutrophication and harmful algal blooms (HABs),
Escalating Worldwide use of Urea – A Global Change Contributing to Coastal Eutrophication
While the global increase in the use of nitrogen-based fertilizers has been well recognized, another change in fertilizer usage has simultaneously occurred: a shift toward urea-based products.
Effect of irradiances up to 2000 μE m−2 s−1 on marine Synechococcus WH7803—I. Growth, pigmentation, and cell composition
TLDR
Results support the notion that nutrient replete Synechococcus have the capacity to grow at maximal growth rates in brightly lit oceanic surface mixed layers.
Mixotrophy, a major mode of nutrition for harmful algal species in eutrophic waters
TLDR
An alternate premise is examined, that many harmful algae which thrive in eutrophic habitats are mixotrophs that respond both directly to nutrient inputs, and indirectly through high abundance of bacterial and algal prey that are stimulated by the elevated nutrients.
Prorocentrum minimum (Pavillard) Schiller A review of a harmful algal bloom species of growing worldwide importance
Prorocentrum minimum (Pavillard) Schiller, a common, neritic, bloom-forming dinoflagellate, is the cause of harmful blooms in many estuarine and coastal environments. Among harmful algal bloom
Release of Dissolved Organic Nitrogen by Marine Diazotrophic Cyanobacteria, Trichodesmium spp

  • 1 November 1994
TLDR
Rates of release of DON showed considerable variation within replicate experiments and were variable depending on time of day and duration of time course experiments, likely a significant source of new nitrogen for the associated bacteria or the non-nitrogen-fixing filaments of the Trichodesmium colonies.
Nitrogen Uptake, Dissolved Organic Nitrogen Release, and New Production
TLDR
In oceanic, coastal, and estuarine environments, traditional nitrogen-15 techniques were found to underestimate new and regenerated production by up to 74 and 50 percent, respectively.
Role of urea in microbial metabolism in aquatic systems: a biochemical and molecular review
TLDR
This review summarizes what is known about urea sources and availability, use of Urea as an organic N growth source, rates of urea uptake, enzymes involved in urea metabolism (i.e. urea transporters, urease, UALase), and the biochemical and molecular regulation ofUrea transport and metabolic enzymes, with an emphasis on the potential for genomic sequence data to continue to provide important new insights.
