Several different sporophytes
were collected in the following two localities.
Generally, the sequence and timing of sporophyte
development for each species was similar for each forest age class so data was pooled for each species and peaks of each phenostage were used to better show the phenological development (Fig.

and direct spore culture (; Figure 2).

tea (reported as Ampithoe tea) on a single Pelvetia fastigiata sporophyte
. The interactive effect of nest-building and feeding activities by kelp-curler amphipods on particular blade tissues (e.g., meristems and the influence on growth rate) is not yet completely understood.
In the first method the whole 'head' of the kelp sporophyte
is cut off between the bulb at the top of the stipe and the primary blade.
Plants have two generations: sporophyte
Each species identified was described morphologically using the gametophyte characters (leaf arrangement, midrib, base, apex, margin, cells, and shape) and sporophyte
characters (size, shape, texture of capsule and seta, number of teeth).
is found in abundance with foot, seta and capsule.
The structure and properties (viscosity, degree of setting) of the carrageenans vary from species to species, and there are even variations between those obtained from the different phases (sporophyte
and gametophyte) of a single species.
