Growth and Reproduction of Dictyota binghamiae J. G. AGARDH

Growth and Reproduction of Dictyota binghamiae J. G. AGARDH Introduction Dictyota binghemiae J* G. AGARDH (1894: 72) is one of the largest species of this widely distributed and common brown algal genus. It is found in the sublittoral, growing at depths from the sublittoral fringe down to 38 m (SMITH, 1969). The species is confined to and widely distributed along the Pacific Coast of North America, ranging from Godkin Pt., Hope Island, British Columbia (NoRRis and ABBOTT, 1972) to central Baja California (DA^SON, 1961). We have found that in the Santa Barbara area this plant is most abundant at depths of 6 --8 m, growing on rocks exposed to moderate surge or current. The present study was undertaken in part to provide a more complete description of the vegetative and reproductive morphology of this plant than has heretofore been available. In addition, vegetative growth rates were measured and the formation and release of gametes and spores was studied. Hopefully the results obtained will contribute to a better understanding of the biology of a plant that has been the subject of some taxonomic confusion in the past (DA\VSONS 1950a; b) and which is a common member of the local keip bed Community.

Abstract

Introduction Dictyota binghemiae J* G. AGARDH (1894: 72) is one of the largest species of this widely distributed and common brown algal genus. It is found in the sublittoral, growing at depths from the sublittoral fringe down to 38 m (SMITH, 1969). The species is confined to and widely distributed along the Pacific Coast of North America, ranging from Godkin Pt., Hope Island, British Columbia (NoRRis and ABBOTT, 1972) to central Baja California (DA^SON, 1961). We have found that in the Santa Barbara area this plant is most abundant at depths of 6 --8 m, growing on rocks exposed to moderate surge or current. The present study was undertaken in part to provide a more complete description of the vegetative and reproductive morphology of this plant than has heretofore been available. In addition, vegetative growth rates were measured and the formation and release of gametes and spores was studied. Hopefully the results obtained will contribute to a better understanding of the biology of a plant that has been the subject of some taxonomic confusion in the past (DA\VSONS 1950a; b) and which is a common member of the local keip bed Community.
