Synonyms; Capea biruncinata var. No. In the field at Goat Island Bay, sporophytes produce the bulk of their spores in late autumn or winter, and gametophyte reproduction follows in winter or spring (depending upon depth) (Novaczek, 1980) when water temperature is generally below 15 ~ Limited recruitment can occur in shallow water in autumn when storms open spaces in the Ecklonia radiata forest. Abstract . Brief description. reproduction and gametophyte growth and survival of Ecklonia radiata (C. Agardh) J. Agardh in south-western Australia. Increasing ocean temperatures are a threat to kelp forests in several regions of the world. Ecklonia radiata is the major habitat-forming kelp in temperate Australia where it plays a pivotal role in structuring shallow, inshore communities, by providing habitat and energy to higher trophic levels.

These results were related to patterns in local environmental conditions in an attempt to ascertain which factors explain variation throughout the season. Within this range, fertile female gametophytes grown at lower temperatures had fewer, larger cells and thus fewer potential ova than those grown at higher temperatures.
