Novel copper‐binding and nitrogen‐rich thiols produced and exuded by Emiliania huxleyi (2004, background): “In surface seawater, copper is complexed by a pool of organic ligands that decreases the bioavailable free ion concentrations from toxic to nutritive levels (van den Berg 1984; Coale and Bruland 1988; Moffett 1995), and variations in copper (Cu) complexation can influence community composition in ma”
Copper requirements for iron acquisition and growth of coastal and oceanic diatoms (2005, background): “Algal species are known to differ greatly in their sensitivities to Cu and their abundances in natural waters are thought in part to be influenced by variations in environmental Cu concentrations (Brand et al. 1986; Mann et al. 2002).”
Is the distribution of Prochlorococcus and Synechococcus ecotypes in the Mediterranean Sea affected by global warming (2011, background): “Indeed,Prochlorococcusgrowth was shown to be strongly affected by fairly low concentrations of this element, while Synechococcuscells can usually withstand higher concentrations (Mann et al., 2002).”
Genome divergence in two Prochlorococcus ecotypes reflects oceanic niche differentiation (2003, background): “Innermost circle (8) represents the GC skew curve.”
Production of cobalt binding ligands in a Synechococcus feature at the Costa Rica upwelling dome (2005, background): “This has been attributed to copper toxicity associated with photodegradation of organic ligands that otherwise would lower copper bioavailability and a higher copper sensitivity in Prochlorococcus than Synechococcus (Mann et al. 2002).”
Influence of light and temperature on Prochlorococcus ecotype distributions in the Atlantic Ocean (2007, background): “Because Prochlorococcus have been documented to grow at rates of about 0.1 d21 (Mann et al. 2002) below the mixed layer in the Sargasso Sea, where variation in ecotype abundance is greatest, it is very unlikely that any changes in growth or mortality rates could account for the order of magnitude…”
The genome of a motile marine Synechococcus (2003, background): “Characterizing these further may put a mechanistic basis behind previous observation”
Ecotypic variation in phosphorus-acquisition mechanisms within marine picocyanobacteria (2005, background): “…isolates (LL ecotypes), which differ in their chlorophyll b/a ratio, photosynthetic capabilities, copper sensitivity, nitrite utilization, and depth distributions (Moore et al. 1998, Moore & Chisholm 1999, Rocap et al. 1999, West & Scanlan 1999, West et al. 2001, Mann et al. 2002).”
Viability and niche segregation of Prochlorococcus and Synechococcus cells across the Central Atlantic Ocean (2004, background): “Also, Mann et al. (2002) recently identified copper toxicity as a factor able to influence Prochlorococcus and Synechococcus distribution in the Sargasso Sea.”
Culturing the marine cyanobacterium Prochlorococcus (2007, methodology): “eReferred to as PRO-TM; used for trace metal studies (Mann et al. 2002; Saito et al. 2002) and for obtaining axenic MED4 and MIT 9312 through plating with the addition of vitamins and spent media from Co-limited cultures (see text; Saito 2001).”
