Abstract
Molecular studies have shown that New Zealands
rocky shores are a habitat for >30 species of Porphyra,
but little is known of their seasonal and zonal
distribution. The spatial and temporal distribution
of bladed Porphyra gametophytes at Brighton Beach,
southeast New Zealand, were monitored for
32 months. Molecular markers were used for species
identification, and a total of nine species was
observed as being present during this time. Two
species, P. cinnamomea and Porphyra sp. ROS 54,
were the most common, and both were present for
most months, while the remaining seven species
were present sporadically, for only a few weeks at a
time. P. cinnamomea W. A. Nelson and Porphyra sp.
ROS 54 were most common in the midintertidal,
and both showed a similar seasonality with the highest
presence during spring. They also showed a similar
trend of seasonal dieback resulting in at least
1 month (May) in two consecutive years when they
were both absent. This is one of the few studies
investigating spatial and temporal distribution within
a genus and over a 3-year period. Our results show
no distinct intertidal zonation patterns within the
genus, and we conclude that morphologically similar
species in a similar habitat rely on physiological
mechanisms for survival.
