CATAMI macroalgal classification aligned with life-history characteristics often used in the derivation of indicators, and with the ecological status groups for monitoring the health of marine systems.

A range of macroalgal indices have been proposed for subtidal environments that utilise morphological and biological traits of species or groups. Table 1 shows how CATAMI macroalgal classifications aligned with life-history characteristics often used in the derivation of indicators, and with the ecological status groups proposed by Orfandis et al. for monitoring the health of marine systems [88].Ecological state group I—late successional species, ecological state group II—opportunistic species.CATAMI macroalgal classification aligned with life-history characteristics often used in the derivation of indicators, and with the ecological status groups for monitoring the health of marine systems.
