Acropora was the most common coral in the collections.
Trends in levels of activity of three othe. genera of corels
vere similar to Acropora, and
absolute levels differed, but
not significantly.
Consider-
ing Acropora levels as unity,
other genera had these values:
Heliopora 2.6, Porites 1.3,
and Pocillopora 0.7.
Samples
at Vera and Olive showed sig-
nificantly greater activity
in Porites than in Pocillopora.
Figure 18 shows that a
gives -2.23 as the slope.
From
1 to 8 (average 3.6170.5) plates
were the basis for #sch point on
the graph.
The decline data of Figure

Projection of the decline curve
into the future would be of
special interest because of the
basic role of corals in the
atolls.

Decays, also, appear in
Figure 18.
Slopes on the same
day are in general agreement,
with the exception of curve -5.
When decline and decay slopes are
compared over identical periods
decays are seen to be appreci-
ably less steep than declines.
Table 13 gives data pertinent to
the decays.
Only the early
portion of curve 5 exceeds the
decline curve in steepness.
