The genus Laminaria sensu lato : recent insights and developments
TLDR
This review about the genus Laminaria sensu lato summarizes the extensive literature that has been published since the overview of the genus given by Kain in 1979, and covers recent insights into phylogeny and taxonomy, and discusses morphotypes, ecotypes, population genetics and demography. Expand
Seasonal variation in ecophysiological patterns in macroalgae from an Arctic fjord. II. Pigment accumulation and biochemical defence systems against high light stress
TLDR
Overall, the synthesis of UV-absorbing substances and the increase in the activity of the antioxidative systems in the open-water period imply an increased resistance to high underwater light conditions, including UV radiation. Expand
Fatty acid composition of Arctic and Antarctic macroalgae: indicator of phylogenetic and trophic relationships
TLDR
The fatty acid composition of 6 Arctic and 14 Antarctic macroalgae species (Rhodo- phyta, Phaeophyta and Chlorophyta) from Kongsfjorden (west Spitsbergen, Arctic) and King George Island was investigated to make fatty acids a potential tracer for studies of food-web interactions. Expand
Distribution of three alien cyanobacterial species (Nostocales) in northeast Germany: Cylindrospermopsis raciborskii, Anabaena bergii and Aphanizomenon aphanizomenoides
TLDR
Investigating the spatial distribution and relative frequency of C. raciborskii close to its northernmost distribution limit and the habitat in which it is most likely to occur in this climatic zone concluded that alien thermophilic cyanobacterial species are much more widely distributed in temperate Germany than previously known. Expand
Chloroidium, a common terrestrial coccoid green alga previously assigned to Chlorella (Trebouxiophyceae, Chlorophyta)
TLDR
All Ch Lorella-like strains related to Chlorella saccharophila and C. ellipsoidea to the genus Chloroidium Nadson and to emend its diagnosis are proposed, as well as four new combinations of these species that are likely to be used as chemotaxonomic marker. Expand
Photoprotective substances in Antarctic macroalgae and their variation with respect to depth distribution, different tissues and developmental stages
TLDR
3 physiologically different groups of algae in terms of MAA values are presented: species with no capability for MAA biosynthesis; species with a basic MAA con- centration which is adjusted relative to changes in environmental radiation; and Species with a relatively high MAA composition and concentration irrespective of environmental conditions. Expand
Natural ultraviolet radiation and photosynthetically active radiation induce formation of mycosporine-like amino acids in the marine macroalga Chondrus crispus (Rhodophyta)
TLDR
While shinorine accumulation was much more stimulated by UVR, the content of all other MAAs was more affected by high PAR, indicating an MAA-specific induction triggered by Uvr or PAR. Expand
Enzymatic defences against photooxidative stress induced by ultraviolet radiation in Arctic marine macroalgae
TLDR
Overall, the ecological success of macroalgae in the eulittoral and upper sublittoral is supported by an enhanced oxygen-reactive scavenging system, allowing fast acclimation to the changes in environmental radiation conditions. Expand
MYCOSPORINE‐LIKE AMINO ACIDS AND PHYLOGENIES IN GREEN ALGAE: PRASIOLA AND ITS RELATIVES FROM THE TREBOUXIOPHYCEAE (CHLOROPHYTA) 1
TLDR
The data presented suggest a chemotaxonomic value of the 324 nm‐MAA in green algal taxonomy and proposes the new combination Lobosphaera incisa to address the paraphyly of the genus Myrmecia Printz as presently circumscribed. Expand
Physiological and morphological processes in the Alpine snow alga Chloromonas nivalis (Chlorophyceae) during cyst formation
TLDR
It is shown that the cysts are photosynthetically highly active, although they do not divide, and that Chloromonas nivalis can cope with low as well as high light conditions, and genetic variations due to spatial isolation are indicated. Expand
