dc.description.abstract | Algae and the associated macrofauna in two
Icelandic intertidal ecosystems under cold and warm
influence, respectively, were studied with respect to algae-macrofauna relationships and a possible effect of
temperature on community structure. Two sites in Iceland were selected, Sandgerdi ligthhouse (648¢N
2240¢W) on the southwestern coast, and Grimsey Island
(6633¢N 1804¢W), in the north, on the Arctic Circle,
where sea temperature is considerably lower (5
approximately). The biomass of algae and the number of
species of algae and macrofauna were higher in Sandgerdi than in Grimsey, and the patterns of diversity,
evenness, biomass and abundance also differed between
the sites. In the intertidal zone of Sandgerdi, a total of 28
species of algae and 45 species of macrofauna were
identified whereas only 16 algal species and 27 macrofaunal species were found in Grimsey. Canonical correspondence analysis (CCA) using algal biomass as the
environmental variable were conducted, and revealed
significant relationships between algae composition and
the associated macrofauna; some macrofauna taxa
showed specific trophic or refuge relationships with algal
species. According to the CCA, Corallina officinalis
showed the highest correlation with macrofaunal
assemblages in both study sites. However, correlations
between macrofauna and other algae differed between
Grimsey and Sandgerdi. The present study, together
with additional observations in Greenland waters, shows
a general decrease of species richness and diversity towards the north which may primarily be due to the
temperature regime. | es |
