Cluster analysis of the fish assemblage structure by monthly variations and tidal rhythm.

<p>Monthly samples were divided according to the tidal rhythm into the following four categories: high tide during semi-diurnal tides (SH), low tide during semi-diurnal tides (SL), high tide during diurnal tides (DH) and low tide during diurnal tides (DL). Months are in the numeric form (1 to 12). Dashed line indicates the 50% cut-off value.
