Nickel. None of the three fish species exhibited
a significant HabType*TL interaction
for nickel (data not shown). Moreover, nickel
concentrations were not significantly associated
with TL in kelp bass (data not shown) and
kelp rockfish (data not shown). However, an
inverse association between nickel concentrations
and TL was observed in Pacific sanddab
(F 1,91.9
=9.91, P=0.002). On average, nickel concentrations
in Pacific sanddab decreased by
4.1% (95% confidence interval, -6.7 to -1.6%)
for every 1.0-cm increase in TL. Nickel concentrations
in all three species (including Pacific
sanddab, after controlling for TL) did not differ
significantly between HabTypes (Figure 16).
Rubidium. Kelp bass and Pacific sanddab
did not exhibit significant HabType*TL interactions
for rubidium (data not shown). In
both fish species, TL was not significantly associated
with rubidium concentrations (data
not shown). Moreover, rubidium concentrations
did not exhibit significant differences
between Habtypes for kelp bass and Pacific
sanddab (Figure 17). On the other hand, rubidium
concentrations in kelp rockfish exhibited
a significant HabType*TL interaction
effect (Figure 18), indicating that the relation
between rubidium concentrations and Hab-
Type differed by TL. On average, rubidium
concentrations in kelp rockfish decreased by
