Role of urea in microbial metabolism in aquatic systems: a biochemical and molecular review (2010, background): “Urea uptake rates in aquatic systems range from <0.1 nM-N h–1 to 3.6 µM-N h–1 (Kristiansen 1983, Berg et al. 1997, Lomas et al. 2002, Berman & Bronk 2003).”
KINETICS OF NITRATE, AMMONIUM, AND UREA UPTAKE BY FOUR INTERTIDAL SEAWEEDS FROM NEW ZEALAND 1 (2004, background): “…may be relatively low (Probyn and Chapman 1983, Plagányi and Branch 2000), urea may be made available through excretion by molluscs (Berman and Bronk 2003), bacterial degradation of dissolved organic N (Antia et al. 1991, Berman et al. 1999), or agricultural runoff (Berman and Bronk 2003).”
Heterotrophy in Tropical Scleractinian Corals (2009, background): “…also by larger animals such as fish, they are generally considered an important nitrogen source for phytoplankton (Maguer, Lecorre & Madec, 1996; Berman & Bronk, 2003) and zooxanthellae (Grover et al., 2006, Biological Reviews 84 (2009) 1–17 2008 The Authors Journal compilation 2008 Cambridge…”
Microbial uptake of dissolved organic and inorganic nitrogen in Randers Fjord (2004, background): “(direct or indirect release by phytoplankton and bacteria) (Berman and Bronk, 2003).”
DON as a source of bioavailable nitrogen for phytoplankton (2006, positive): “…balance their DON consumption with uptake of inorganic nutrients (Wheeler and Kirchman, 1986; reviewed in Kirchman, 2000), but also that phytoplankton from various marine ecosystems use DON to meet their cellular N demands (reviewed in Antia et al., 1991; Bronk, 2002; Berman and Bronk, 2003).”
Effects of nutrients, salinity, pH and light:dark cycle on the production of reactive oxygen species in the alga Chattonella marina (2007, background): “…nitrogen (DIN), recent work has revealed that dissolved organic nitrogen (DON, including urea, dissolved free amino acids, and nucleic acids) may also serve as important nitrogen sources for many phytoplankton species, including HAB-causative species (Anderson et al., 2002; Berman and Bronk, 2003).”
The role of nitrogen in promoting the toxic cyanophyte Cylindrospermopsis raciborskii in a subtropical water reservoir (2006, background): “Compounds such as urea and free amino acids in the dissolved organic nitrogen (DON) pool can also be utilised by a wide range of phytoplankton (Berman & Bronk, 2003).”
Comparison of nitrogen fixation rates determined with different methods: a study in the Baltic Proper (2005, background): “A potential alternative internal nitrogen source is DON (Berg et al. 2003, Berman & Bronk 2003, Glibert et al. 2004).”
Pluses and minuses of ammonium and nitrate uptake and assimilation by phytoplankton and implications for productivity and community composition, with emphasis on nitrogen‐enriched conditions (2016, background): “…forms of N used by phytoplankton, nor is NH14 the only form of chemically reduced N that is increasing, as dissolved organic nitrogen (DON) is recognized to be increasingly important and a dynamic N form in phytoplankton nutrition (Berman and Bronk 2003; Glibert et al. 2006; Solomon et al. 2010).”
Evidence for dissolved organic nitrogen and phosphorus uptake during a cyanobacterial bloom in Florida Bay (2004, background): “In a recent review of DON utilization by phytoplankton (Berman & Bronk 2003), it was clearly shown that not only can many species utilize DON, but many types of DON are utilized by phytoplankton.”
Ecological Stoichiometry, Biogeochemical Cycling, Invasive Species, and Aquatic Food Webs: San Francisco Estuary and Comparative Systems (2011, background): “Unfortunately, much still is not known about the bioavailability of most organic N and P constituents (Seitzinger et al., 2002b; Berman and Bronk, 2003).”
P-limited bacteria but N and P co-limited phytoplankton in the Eastern Mediterranean—a microcosm experiment (2005, background): “This conflicts somewhat with the growing body of literature demonstrating that phytoplankton and especially cyanobacteria do utilize DON (reviewed by Berman and Bronk, 2003 ), but this issue cannot be resolved until we know more about the composition and utilization of DON in the Eastern Mediterran”
Seasonal phytoplankton nutrient limitation patterns as revealed by bioassays over Baltic Sea gradients of salinity and eutrophication (2007, background): “Although both algae and bacteria have been shown to utilize organic N and P, this is more widespread in heterotrophic nutrition (e.g. Berman & Bronk 2003).”
