Marginal Coral Populations: the Densest Known Aggregation of Pocillopora in the Galápagos Archipelago is of Asexual Origin Frontiers in Marine Science (2014)
Coral populations at distributional margins frequently experience suboptimal and variable conditions. Recurrent El Niño-Southern Oscillation (ENSO) warming events have caused extensive mortality of reef-building corals in the Eastern Pacific, and particularly impacted branching pocilloporid corals ...

Status of Coral Reefs of Little Cayman, Grand Cayman and Cayman Brac, British West Indies, in 1999 and 2000 (Part 1: Stony Corals and Algae) Atoll Research Bulletin (2003)
A benthic assessment of the isolated Cayman Islands was completed at 42 sites. Major changes in the reef community structure were documented by comparison with earlier studies. Acropora palmata and A. cervicornis, once abundant as ...
Responses of Three Coral Communities to the 1997–98 El Niño–Southern Oscillation: Galápagos Islands, Ecuador Bulletin of Marine Science (2001)
One deep (13–15 m depth) and two shallow water (1.5 and 7 m) coral communities in the Galápagos Islands, Ecuador were monitored for tissue response (bleaching, paling, morbidity) and secondary responses during and after elevated ...
Experimental Studies of Rapid Bioerosion of Coral reefs in the Galápagos Islands Coral Reefs (1996)
Experimental carbonate blocks of coral skeleton,Porites lobata (PL), and cathedral limestone (LS) were deployed for 14.8 months at shallow (5–6 m) and deep (11–13m) depths on a severely bioeroded coral reef, Champion Island, Galápagos Islands, ...
Reef Coral Reproduction in the Eastern Pacific: Costa Rica, Panamá, and Galápagos Islands (Ecuador). II. Poritidae Marine Biology (1994)
A comparative study of the reproductive ecology of the zooxanthellate, scleractinian corals Porites lobata Dana and P. panamensis Verrill was conducted from 1985 to 1991 in eastern Pacific reef environments that were severly impacted by ...
The Effect of Temperature on the Benthic Stages of Cyanea (Cnidaria: Scyphozoa), and Their Seasonal Distribution in the Niantic River Estuary, Connecticut Journal of Experimental Marine Biology and Ecology (1991)
There are three benthic stages in the life history of Cyanea: the polyp stage and two kinds of cysts; one kind is produced by the polyp (podocysts), and the other by the planula larvae (planulocysts); ...
