Molecular ecological studies of New England species of Porphyra (Rhodophyta, Bangiales)
Conspicuous spatial and temporal patterns were recorded for several populations of Porphyra. The high intertidal zone at Fort Stark was dominated throughout the year by the aseasonal annual P. 'umbilicalis', while the low intertidal at the same site had a distinct summer maximum consisting of P. 'leucosticta' and P. 'umbilicalis'. By contrast, P. 'umbilicalis' and P. 'purpurea' dominated the high intertidal zone at Dover Point, except during winter-early spring months when P. 'yezoensis' was most conspicuous. Porphyra 'purpurea' and P. 'yezoensis' were most abundant within the low intertidal zone at Dover Point, with the former plant being present almost year round and the latter having a distinct winter-early spring maximum. The mean lengths of P. 'umbilicalis', P. 'leucosticta' and P. 'purpurea' were largest during summer and, when present, smallest in winter.

- Nova Hedwigia is an international journal publishing original, peer-reviewed papers on current issues of taxonomy, morphology, ultrastructure and ecology of all groups of cryptogamic plants, including cyanophytes/cyanobacteria and fungi. The half-tone plates in Nova Hedwigia are known for their high quality, which makes them especially suitable for the reproduction of photomicrographs and scanning and transmission electron micrographs.
