Healthy P. clivosa<\/em> on the Reef Flat, Jan 15, 2024.\u00a0Click on images for larger versions. <\/em>More Pics<\/a><\/p><\/div>\n

Large mounds of Pseudodiploria clivosa <\/em>are common on the Reef Flat and Diploria-Palytoa zones at Vauxhall and can assume some quite striking, even majestic, forms.<\/p>\n

I had not seen diseased Pseudodiploria clivosa<\/em> amongst these big specimens\u00a0 at Vauxhall until I viewed this large specimen on the Reef Flat, Mar 10, 2024. It’s a large specimen,\u00a0 located about 1\/3rd of the distance out from shore to the Reef Crest area. It has\u00a0 symptoms of Stony Coral Tissue Loss Disease (view AGGRA Card<\/a>), “the most devastating coral disease outbreak ever recorded” (1).<\/p>\n\n\n\n

Approx.\u00a0 route on Mar 10, 2024. , Asterisk shows location of diseased P clivosa<\/p><\/div>\n

In studies of SCTLD, P clivosa<\/em> has been cited as one of the Highly\u00a0 Susceptible\u00a0(2) or More Susceptible species (3).\u00a0 While P. clivosa is an common coral at Vauxhall, most specimens I have viewed were disease free. In 2023, McGill students observed far fewer diseased specimens of\u00a0\u00a0P clivosa<\/em> than they did for P. strigosa<\/em> (4).<\/p>\n

What makes particular coral species or particular specimens susceptible to SCTLD is not well understood (1). Perhaps there is resistance at the individual specimen level, perhaps not, or there may be interactions with other factors, e.g. heat stress (4).<\/p>\n

It should be informative to monitor this Reef Flat population in future, fingers crossed!<\/p>\n
