Doctoral Dissertations
To investigate the phylogeography of the rocky intertidal red alga, Porphyra umbilicalis Kutzing, a restriction fragment polymorphism assay (RFLP) of the ribulose bisphosphate carboxylase large subunit ( rbcL) was developed to accurately distinguish P. umbilicalis from the other morphologically similar species in the North Atlantic. Initial screening of ∼800 Porphyra specimens resulted in the additional discovery of a cryptic Porphyra taxon.
The presence and variability of group-I introns of the ribosomal small subunit (SSU) were screened in North Atlantic species of Porphyra in order to assess whether they could be biogeographically informative. In an initial screening for the helix 50 …
