[Coral-List] A couple rays of hope??

Dear Douglas and John

Interesting comments. I agree that the healthy coral cover isn’t the only
measure of coral reef “health”. In fact, a classic publication shows a long
list of indicators of state that should be evaluated within a multicriteria
analysis to measure conservation effectiveness:
*Galvis, N.H., 2001. Monitoring ecological and socioeconomic indicators for
management of coral reefs in Colombia. Proceedings of the International
Conference on Scientific Aspects of Coral Reef Assessment, Monitoring, and
Restoration. Bulletin of Marine Sciences ISSN 0007-4977 69(2) Sept.
847–859(13) *
http://www.ingentaconnect.com/content/umrsmas/bullmar/2001/00000069/00000002/art00047

The evaluation and monitoring of all those indicators as coral cover should
also be studied per area to compare changes in situ. If a significant lost
or difference of 10% is found within an increasing trend of deterioration,
in an area close to places where there are anthropogenic activites then it
is an alert that it is necessary to improve local adaptive management. If
after a bleaching event there is recovery then the coral cover is expected
to recover more quickly, in areas where there is not so much human negative
impact. According to Smith et al (2016
<http://rspb.royalsocietypublishing.org/content/283/1822/20151985>) the
average coral cover was greater on reefs adjacent to uninhabited islands
(24 vs 15%). However, this difference was non-significant. Most of the
studies on the Caribbean Coral Cover have reported significant lost in
areas close to human activities.  Anyway, it is better to prevent negative
impacts to coral reefs with effective conservation.

For future studies is necessary to consider what Baker (2016) point out
that in the quest for certainty, statisticians issue warning over misuse of
P values
