Fig. 6.7. Relationship between
oxidation rate of LYA-lysine
(nMh- 1 ) and water temperature
(OC) at time of sampling. All
samples taken are shown; when
rates were below detection limits, the number of samples (n)
is indicated (reprinted from
Pantoja and Lee 1994, with permission from ASLO)

concentration of ammonium at
the time of sampling in several
environments (data extracted

Ambient ammonium (iJM)
tions display more versatile pathways to obtaining nutrients they require than we have
traditionally thought.
