    Notes: Abstract The benthic algal vegetation of Mjóifjörđur, situated in the central area of the East Icelandic coast, is described regarding the species distribution from the head to the mouth of the fjord, the main algal associations and zonation patterns. The vegetation gradient along the fjord coast is related to the hydrographic conditionsviz. the influence of freshwater discharge in the inner area and that of the cold water masses of the East Icelandic Current in the outer area. Comparisons are made with the vegetation of other Icelandic fjords investigated during surveys of the Icelandic algal vegetation as a whole.

    Gradient in seaweed vegetation patterns along the North Icelandic coast, related to hydrographic conditions (1992)
    Springer
    Hydrobiologia 242 (1992), S. 133-147 
    Details
    ISSN: 1573-5117
    Keywords: Icelandic seaweeds ; vegetation gradient ; algal association ; zonation patterns ; northern Iceland ; hydrographic conditions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The benthic algal vegetation of the North Icelandic coast exhibits particular features, different from those found in southern and western Iceland on the one hand and in eastern Iceland on the other. It is characterised by low-eulittoral belts of Devaleraea ramentacea, Petalonia species and Chordaria flagelliformis as well as by meadows of diverse Acrosiphonia species. In the tide pools Atlantic and typical North Icelandic associations occur side by side. This area thus represents an intermediate region between Atlantic and subarctic growth conditions. A certain gradient in the west-east direction was observed within the North Icelandic vegetation type and is possibly related to the gradual cooling and dilution of the water masses which pass the North Icelandic shelf. The hydrographic discontinuity in the extreme NW creates a sharp floristic and vegetational boundary for benthic algae, whereas in the NE a gradual transition towards the subarctic East Icelandic vegetation was observed. The Atlantic character of the vegetation was more pronounced in the western than in the eastern part of the north coast. An enclave of warm water vegetation was interposed along the western banks of the Tjörnes peninsula.

    Resources and possibilities for exploitation of North Adriatic seaweeds (1990)
    Springer
    Hydrobiologia 204-205 (1990), S. 309-315

    ISSN: 1573-5117
    Keywords: Adriatic seaweeds ; algal resources ; alginic acid content ; biomass ; protein content
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Suggestions for a small-scale exploitation of seaweeds in the northern Adriatic are given along with a survey of the fresh weight biomass and chemical composition of individual species. The intertidal is occupied by Fucus virsoides. In polluted sites, it is replaced by seasonal annuals. Cystoseira species are dominant in the upper subtidal and represent the major part of seaweed resources in this area. In polluted sites they are replaced by Halopteris scoparia and Dictyota dichotoma. Peaks in biomass were found in spring in the upper water layers and in early summer lower in the subtidal. The protein content of most species exhibited maxima in spring. Elevated values were found in plants from polluted and estuarine habitats.

    Changes and degradation of seaweed stands in the Northern Adriatic (1993)
    Springer
    Hydrobiologia 260-261 (1993), S. 239-253 
    Details
    ISSN: 1573-5117
    Keywords: algal associations ; zonation patterns ; fucoids ; pollution impact ; eutrophication
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract During the last two decades conditions in the polluted shelf area of the Northern Adriatic became critical, leading to eutrophication and anoxia. They are reflected in changes and degradation of the macrophytobenthos with simultaneous increase of phytoplankton blooms. Pollution-induced changes of the benthic algal vegetation comprise altered zonation patterns and leading algal associations along with a decrease in species number and fresh weight biomass. A reduction or absence of fucoid stands was observed in the eulittoral and sublittoral. Fucus virsoides was in most cases replaced by ephemeral species which form distinct zones during spring and by turf-like mats of Gelidium pusillum. Sublittoral Cystoseira stands were either reduced or absent, replaced by populations of Halopteris scoparta, Dictyota dichotoma, Halopithys incurvus, Padina pavonica and under extreme conditions by Ulva rigida with Scytosiphon lomentaria and Enteromorpha species during spring. A decreased depth penetration of macroalgae was observed in polluted sites. It seems likely that amorphous mucus aggregations resulting probably from excess phytoplankton blooms which were found during summer months of the last few years, have a deleterious effect on macroalgae.

    The benthic algal vegetation of land-locked fjords in southeastern Iceland (1999)
    Springer
    Hydrobiologia 393 (1999), S. 169-180 
    Details
    ISSN: 1573-5117
    Keywords: land-locked fjords ; S.E. Iceland ; vegetation gradients ; algal associations ; filamentous algae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Land-locked fjords, which communicate with the open sea through narrow channels, were studied along the hydrographic boundary area in southeastern Iceland. There is an ample freshwater supply into these fjords. Growth conditions for benthic algae range from marine over brackish to limnic. The benthic algal vegetation is dominated by filamentous brown and green algae, found mainly in loose, entangled mats. Fucoids are subordinate and form continuous populations only close to the channels. Giant specimens of foliose algae (Ulva lactuca, Ulvaria and Monostroma species, Porphyra purpurea) were found attached to pebbles in sandy habitats). Chorda filum dominates in the sublittoral and is locally accompanied by Laminaria saccharina (in a broad growth form). A vegetation gradient from the entrance towards the innermost areas of these fjords was obvious. On soft substrata Vaucheria spp. are common. Admixture of marine phanerogams (e.g. of Ruppia maritime) into the benthic algal vegetation is also a characteristic feature.
