LIFE HISTORY AND GROWTH OF LAURENCIA BRACHYCLADOS (RHODOPHYTA, CERAMIALES)

Laurencia brachyclados Pilger from Hawaii completed a "Polysiphonia -type" tri-phasic life history in 21 weeks in laboratory culture. Tetraspores developed into gametophytes in a nearly 1:1:1 ratio of females:males:non-reproductive. Carpospores were released as early as 21 days after mixin...

Zusammenfassung:	Laurencia brachyclados Pilger from Hawaii completed a "Polysiphonia -type" tri-phasic life history in 21 weeks in laboratory culture. Tetraspores developed into gametophytes in a nearly 1:1:1 ratio of females:males:non-reproductive. Carpospores were released as early as 21 days after mixing virgin female and male gametophytes. Cultured thalli showed a "guerilla type" growth form. Other Hawaiian Laurencia species in culture had longer maturation times or remained non-reproductive. Variation in life history schedules may influence Laurencia species coexistence and algal community structure.
