[Coral-List] Cold water and coral mortality

[James Cervino PhD.]

Good day Gene; here is a paper that discusses the Biology and Physiology
pertaining to corals as it pertains to cold stress.

Steen RG, Muscatine L (1987) Low temperature evokes rapid exocytosis
of symbiotic algae by a sea anemone. Biol Bull 172:246–
263

* For those interested in what may lie ahead here are some "ancient"
* pre pdf papers describing effects of cold fronts/cold water on common
* species of corals in the Florida Keys.
*
* 1) In this study water temperature below 14 degrees C during a cold
* event in Feb 1962  killed transplanted A cervicornis in the Fla Keys
* Keys.
* Shinn, E. A., 1966, Coral growth-rate, an environmental indicator:
* Journal of Paleontology, v. 40, no. 2, p. 233-240.
*
* 2) In this study  transplanted M. annularis  was killed by 9.7
* degrees C at Snake creek Jan 20, 1977
* Hudson, J. H., 1981, Response of Montastrea annularis to
* environmental change in the Florida Keys, Proceedings, Forth
* International Coral Reef Symposium 2 Manila. pp. 233-240
* More details of that low water temperature event are in:
*
* 3) Roberts, H. H., Rouse, L. J.,Jr., Walker, N. D., and Hudson, J.
* H., 1982, Cold-water stress in Florida Bay, and northern Bahamas--a
* product of winter cold-air outbreaks. Journal of Sedimentary
* Petrology, v. 52 pp. 0145-0155.
*
* 4) The same cold event (Snow in Miami) killed many acres of A.
* cervicornis at Dry Tortugas as described by:
*   Davis, G. E., 1982, A century of natural change in coral
* distribution at the Dry Tortugas: a comparison of reef maps from 1881
* and 1976. Bulletin of Marine Science, v. 32, pp. 608-623.
*
* The Jan 20 1977 event (when snow flurries were seen in Homestead,
* Florida) literally wiped out A. cervicornis on all shallow bank areas
* of the Tortugas. This species recovered but was later exterminated by
* disease between 1983 and 1984. Staghorn coral remains in decline at
* Tortugas. These studies led coral biologists to believe that low
* water temperature controls the distribution of of Staghorn and
* Elkhorn in the Florida Keys thus limiting them to the outer margin of
* the reef tract. Gene
