Structures of Fucus spiralis, Fucus vesiculosus and Ulva sp. collected in the Paulina intertidal area.
Table 1.
Summary of the collected samples (number of replicates for every sampling time x algal species x sample type) in the Paulina area in November and April.
‘Clean’ algae were not prominently covered with biofilms, whereas algae ‘with sediment’ had prominent biofilms with sediment embedded. In November, clean Fucus vesiculosus were very rare and therefore were not sampled.
Fig 2.
Average proportional abundances of Pm I, Pm II and Pm III adults and juveniles at two sampling times in (a) November and (b) April on Fucus spiralis (n = 6, except for the first sampling in November, where n = 4), Fucus vesiculosus (n = 6) and Ulva sp. (n ≥3). Proportions of Fucus spp. are an average of the relative abundances of L. marina on all algal structures.
Table 2.
PERMANOVA results from the analysis of the proportions of Pm I, Pm II and Pm III adults and juveniles as a function of algal species, month and sampling time (nested in month).
Significant differences (P<0.05) are highlighted in bold.
Table 3.
Pairwise test results on the significant effect of algal species in the cryptic species composition for juveniles and on the significant interaction of algal species and month for adults.
Significant differences (P<0.05) are highlighted in bold.
Fig 3.
Average proportional abundances of Pm I, Pm II and Pm III adults and juveniles on different structures of Fucus spiralis (in order: receptacula, thalli and non-fertile tips; n = 6, except for the first sampling in November, where n = 4) and Fucus vesiculosus (in order: receptacula, thalli and bladders; n = 6) for the two sampling moments (n = 6) in (a) November and (b) April.
Table 4.
PERMANOVA results from the analysis of the cryptic species composition of adults and juveniles on Fucus spiralis and Fucus vesiculosus as a function of algal structures and month, with sampling time nested in month.
Significant differences (P<0.05) are highlighted in bold.
Table 5.
Pairwise test results on the significant effect of algal structure in the cryptic species composition for adults on Fucus spiralis and on the significant interaction of algal structure and month for juveniles on Fucus spiralis and for both stages on Fucus vesiculosus.
Significant differences (P<0.05) are highlighted in bold.
