Competition may occur among other reef communities. Grazing by urchins and fishes is important in preventing seaweeds from overgrowing the reef. The dominant algae on a healthy reef are usually fast-growing filamentous forms or coralline algae, well protected by calcification (hardening) and the pro...
Coral reef degradation and loss will continue for the foreseeable future, particularly in those areas where evidence of systemic stress and global warming is substantial. FAQ’s on Effects of Global Warming on Coral Reefs Essay Question 1. What is the direct effect of global warming on corals?
Competition may occur among other reef communities. Grazing by urchins and fishes is important in preventing seaweeds from overgrowing the reef. The dominant algae on a healthy reef are usually fast-growing filamentous forms or coralline algae, well protected by calcification (hardening) and the pro...

Despite the wonders of innovation and science, there remains no better way to protect reefs than to preventtheir destruction in the first place. Scientists know that every intervention, however well-intentioned, could haveconsequences for the ecological balance ofecosystems. What's more, no technique...

The main effects of nutrients on corals appear to be indirect. The higher nutrient levels result in increased algal growth which can ultimately lead to complete destruction of the delicately balanced coral reef ecosystem. The available evidence implies that denitrification and phosphorus removal are ...
