white plague disease outbreak in a coral reef at los roques national park, venezuela.coral diseases have been reported as a major problem affecting caribbean coral reefs. during august 2000, a coral mortality event of white plague disease-ii (wpd-ii) was observed at madrizqui reef in los roques national park, venezuela. this disease was identified as the major cause of coral mortality, affecting 24% of all colonies surveyed (n = 1 439). other diseases such as black band disease (bbd), yellow blotch disease (ybd), dark spots disease (dsd) and white band disease (wbd) were also re ...200315264552
sexual reproduction of the reef-building coral diploria labyrinthiformis (scleractinia: faviidae), in the colombian caribbean.sexual reproduction of the coral diploria labyrinthiformis was studied for the first time. monthly histological analyses at the corales del rosario national park (colombian caribbean) from may 1997 to april 1998 show that d. labyrinthiformis is a hermaphroditic broadcasting species. it presents an annual gametogenic cycle with a 10-11 month period for gonad investment, in which oogenesis begins in august and ends in may-june. spermiogenesis is short because sperm cysts were only observed in may ...200417354395
[effect of herbivorous and corallivorous fishes on the survival of transplanted corals in the colombian caribbean].to examine the effects of herbivorous and corallivorous fishes on the survival of transplanted colonies of montastraea annularis, diploria labyrinthiformis and porites astreoides, both transplanted and native colonies were full-cage enclosed and compared to open (uncaged) colonies, while caging effects were assessed with a partial-cage (roof treatment). to evaluate if transplant stress increased the corals availability to fish predation, comparisons of fish foraging intensity among transplanted ...200719086388
the roles of temperature and light in black band disease (bbd) progression on corals of the genus diploria in bermuda.on bermuda reefs the brain coral diploria labyrinthiformis is rarely documented with black band disease (bbd), while bbd-affected colonies of diploria strigosa are common. d. labyrinthiformis on these reefs may be more resistant to bbd or less affected by prevailing environmental conditions that potentially diminish host defenses. to determine whether light and/or temperature influence bbd differently on these two species, infection experiments were conducted under the following experimental tre ...201021168414
