|
What is allelopathy? |
Competition for space. |
|
|
What is chemotaxis? |
Pheromones and sex attractants. e.g. signal for numerous coral species to spawn at the same time |
|
|
What are commensal associations? |
Symbiosis. Two species working together. |
|
|
What are settlement cues? |
Chemicals that attract larvae or other propagules that may be floating in the water column and prompt them to settle on a surface (substratum). |
