SECTION I.—ON THE DISTRIBUTION OF CORAL-REEFS, AND ON THE CONDITIONS FAVOURABLE TO THEIR INCREASE. With regard to the limits of latitude, over which coral-reefs extend, I have nothing new to add. The Bermuda Islands, in 32° 15′ N., is the point furthest removed from the equator, in...
The green alga Dictyosphaeria cavernosa (Forskl) Brgesen competes with corals for space on the slopes of patch and fringing reefs in Kane'ohe Bay, O'ahu, Hawai'i. Macroscopic algae rarely occur on pristine coral reef slopes, but are increasingly common at sites of anthropogenic nutrient ...
Researchers have measured the dynamics of coralreefgrowth in the central Red Sea, establishing a baseline that can be used to evaluate how the reefs are affected by climate change or events, such as the global bleaching event of 2015-2016. To get a complete picture of reef growth, the team...

Darwin's work on Coral Reefs (NATURE, vol. x., pp. 408-410), Prof. Dana adduces four examples of islands in which he thinks comparatively recent volcanic action has prevented the formation of extensive coral reefs. One of these is Savaii, the largest island of Samoa....

(1) Basic Concept The early stages of coral growth and reef building, and also the distribution of reefs, are largely controlled by geomorphological, structural and ecological factors (see Coral Reefs—Morphology and Theories ). Gradually, however, the winds and currents gain in importance and, ...
This study examined the daily otolith incremental widths of juvenile Neopomacentrus bankieri, a planktivo- rous damselfish, from three inshore coral reefs in the Great Barrier Reef. Measurements of turbidity, temperature, wave action, and tidal forcing at each reef were taken every 10 minutes ...
