초록
Ecological characteristics of Undariopsis peterseniana, an endangered brown alga, were investigated from January to December 2007 at Jeju Island, Korea. The U. peterseniana population formed dense patches at depths of 12~17 m depth. Growth in length of the alga reached a maximum of 168±36cm at June. Sorus were observed from May to August, and a maturation peak was detected in June, when bottom seawater temperatures were around 18℃. After zoospore release, the alga bleached and disappeared after August. Developmental initiation of sporophytes occurred at temperature above 15℃, and sorus formation required approximately 236 degree-days. This is the first study to examine a U. peterseniana population throughout the entire year in a natural habitat.

Sorus were observed from May to August, and a maturation peak was detected in June, when bottom seawater temperatures were around 18℃. After zoospore release, the alga bleached and disappeared after August. Developmental initiation of sporophytes occurred at temperature above 15℃, and sorus formation required approximately 236 degree-days. This is the first study to examine a U. peterseniana population throughout the entire year in a natural habitat.
