Seasonal variation in the attachment strength of blue mussels: Causes and consequences
The midintertidal zone of temperate rocky coasts is often dominated by mussels that form dense beds and exclude other primary space holders. The rate at which storms remove mussels from their substrate consequently has a controlling influence on intertidal community structure. The rate of disturbanc...

The midintertidal zone of temperate rocky coasts is often dominated by mussels that form dense beds and exclude other primary space holders.
