“…The second group includes species with more eurythermal temperature requirements: Enteromorpha clathrata, Enteromorpha intestinalis, Pol ysiphonia urceolata, Ulva lactuca, Chaetomorpha tortuosa, Bangia atropurpurea, Eudesme virescens. The growth range was between 0 and 20 ~ with optimum growth between 10 and 15~ typical for cold-temperate algae (Bolton & Lfining, 1982;Lfining, 1984;Lfining, 1985;tom Dieck 1992btom Dieck , 1993Wiencke & tom Dieck, 1990). These algae survived up to 24 or even 31 ~ similar to warm-and cold-temperate species (Yarish et al, 1987;Cambridge et al, 1987;L(ining, 1990).…”

“…The first group includes species with more stenothermal temperature requirements: Acrosiphonia arcta, Acrosiphonia sonderi, Urospora penicilliformis, Devaleraea ramentacea, Desmarestia aculeata, Pilayella littorah's, Chromastrum secundatum, Chromastrum virgatulum, Chordaria flagelliformis. These algae displayed a high degree of cold adaptation with respect to the growth ranges (mostly 0-15 ~ and optima (0-10 ~ The USL's (17-23 ~ were however -with the exception of C. secundatum and D. ramentacea -similar to those of algae from the cold-temperate regions (Bolton & Lfining, 1982;Lfining, 1984;Lfining, 1985;Liining & Freshwater, 1988;tom Dieck, 1992btom Dieck, , 1993Wiencke & tom Dieck, 1990).

“…Using the test methods of the present study, a growth optimum at 0~ can also be expected in the Antarctic isolates of these species. The USL's from the Arctic isolates of A. arcta and U. penicilliformis were 22 or 23 ~ respectively (Table 3), and from the Antarctic isolates 22 or 19 ~ respectively (Wiencke & tom Dieck, 1990). The available data indicates an ecotypic variation in the temperature requirements for survival, and presumably also for growth, in the different Northern and Southern Hemisphere populations of these two species.…”

“…3). Wiencke & tom Dieck (1990) determined growth optima at 5 ~ for isolates of A. arcta and U. penicfltiformis from King George Island (Antarctica). These rates were (in contrast to the current study) calculated over the whole investigation period of 28 days (+ 7 days for acclimation).…”

The temperature requirements for growth and upper temperature tolerance were determined in 16 macroalgal species collected on Disko Island (Greenland). The upper survival temperatures were examined in 1 ~ steps, and growth measured at 5~ intervals between 0 and 20 ~ using a refined method, where the fresh weight was determined weekly or fOrtnightly over a period of 5 or 6 weeks. To express temperature-growth responses, growth rates of temperatureacclimated plants were taken. Two groups with different temperature requirements were identified: The upper survival temperatures in these species and inChaetomorpha tortuosa, Bangia atropurpurea and Eudesme virescens were between 24 and 31 ~ These algal species showed little adaptation to the Arctic temperatures. In contrast, algae from the first group exhibited a relatively high adaptation to low temperatures -approaching the low temperature requirements of Antarctic algae. The results are discussed in relation to the geographic distribution of individual species.

“…In general, the water temperature in Antarctic ranges from -1.8 to 5.0°C no matter in winter or in short summer (Wiencke and Dieck 1990). The freshwater Antarctic phytoplanktons are able to grow under the constant low temperatures from 0 to 5.0°C (Priddle et al 1986).…”

Stichococcus, a genus of green algae, distributes in ice-free areas throughout Antarctica. To understand adaptive strategies of Stichococcus to permanently cold environments, the physiological responses to temperature of two psychrotolerants, S. bacillaris NJ-10 and S. minutus NJ-17, isolated from rock surfaces in Antarctica were compared with that of one temperate S. bacillaris FACHB753. Two Antarctic Stichococcus strains grew at temperature from 4 to 25°C, while the temperate strain could grow above 30°C but could not survive at 4°C. The photosynthetic activity of FACHB753 at lower than 10°C was less than that of Antarctic algae. Nitrate reductase in NJ-10 and NJ-17 had its optimal temperature at 20°C, in comparison, the maximal activity of nitrate reductase in FACHB753 was found at 25°C. When cultured at 4-15°C a large portion of unsaturated fatty acids in the two Antarctic species was detected and the regulation of the degree of unsaturation of fatty acids by temperature was observed only above 15°C, though the content of the major unsaturated fatty acid aC18:3 in FACHB753 decreased with the temperatures elevated from 10 to 25°C. Elevated nitrate reductase activity and photosynthetic rates at low temperatures together with the high proportion of unsaturated fatty acids contribute to the ability of the Antarctic Stichococcus to thrive.

Life strategy, ecophysiology and ecology of seaweeds in polar waters

Polar seaweeds are strongly adapted to the low temperatures of their environment, Antarctic species more strongly than Arctic species due to the longer cold water history of the Antarctic region. By reason of the strong isolation of the Southern Ocean the Antarctic marine flora is characterized by a high degree of endemism, whereas in the Arctic only few endemic species have been found so far. All polar species are strongly shade adapted and their phenology is finely tuned to the strong seasonal changes of the light conditions. The paper summarises the present knowledge of seaweeds from both polar regions with regard to the following topics: the history of seaweed research in polar regions; the environment of seaweeds in polar waters; biodiversity, biogeographical relationships and vertical distribution of Arctic and Antarctic seaweeds; life histories and physiological thallus anatomy; temperature demands and geographical distribution; light demands and depth zonation; the effect of salinity, temperature and desiccation on supraand eulittoral seaweeds; seasonality of reproduction and the physiological characteristics of C.
