Life history strategies of three species of Cystophora (Phaeophyta, Fucales) from a shallow subtidal community in South Australia / by Sarah L. Hotchkiss.
A number of life history traits were quantified for three species of Cystophora. The composition and dynamics of the community were monitored and related to temporal changes in the patterns of growth and reproduction of each species, and also to patterns of recruitment and early community …
