Using snorkelers and SCUBA divers is not the best way to monitor fish populations, if we want to know the evolutionary effects of overfishing. The fish population in coral reef areas is often assessed by snorkelers or SCUBA divers, but new research shows that these methods may misrepresent the number of fish.
The study for the first time tested coral larvae in a method that has been used previously to test fish, and found that young coral have strong preferences for odors from healthy reefs. "Not only are coral smelling good areas versus... Read Post
A team of scientists from Canada and Australia has discovered that a decline in shark populations is detrimental to coral reefs. "Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous... Read Post
Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs. Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the deg... Read Post
