Cystoseira
''Cystoseira'' is a genus of brown algae in the order Fucales. Description As presently defined, ''Cystoseira'' comprises fucoids characterised by Antheridium, antherozoids without stigmata, few Antheridium, antheridial branches, trichothallic hairs in conceptacles, large ovoid oospheres, and eggs that remain attached to the surface of the Receptacle (botany), receptacles through mucilaginous stalks until after fertilization. Distribution ''Cystoseira'' as presently defined occurs only in the Mediterranean and Northeast Atlantic. Species from the Indian and Pacific oceans are presently included in different genera. Ecology ''Cystoseira'' are important habitat-forming species in coastal waters of the Mediterranean and Northeast Atlantic. They require good water quality, and can be used as bioindicators for pollution levels. Species ''Cystoseira'' was recently found to include multiple unrelated lineages. As a result, most species were moved to the genera ''Stephanocystis'', ''Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
