“…These data are in accordance with the results of Hammer (1968Hammer ( , 1969. If low salinity is obtained by dilution of sea water with distilled water, algae usually showed a linear decrease of photosynthetic activity.…”

“…Ogata and Matsui (1965) and Hammer (1968Hammer ( , 1969 have also noted that photosynthesis depends on the content of bicarbonate ions in the media. This was the reason that in the investigated algae (except in Wrangelia penicillata) the rates of oxygen production were always less at 38°/ 00 S and 42°/ 00 S than in diluted sea water.…”

“…The influence of temperature, salinity, dessication, pH, and polluted water on the assimilation rate of various marine plants has been studied by several authors (Legendre, 1921;Montfort, 1931;Gessner andHammer, 1960, 1971;Schwenke, 1960;Blinks, 1963;Munda, 1963Munda, , 1974Ogata and Matsui, 1965;Nellen, 1966;Hammer, 1968Hammer, ,1969Gessner, 1969;Biebl and McRoy, 1971;Mathieson and Burns, 1971;Ogata and Schramm, 1971;Burns and Mathieson, 1972. Artifical sea water or natural sea water diluted with distilled water was used in most of these experiments.…”

In the littoral algae Fucus virsoides, Ulva lactuca, Porphyra leucosticta and the sublittoral Wrangelia penicillata the combined effects of salinities and temperatures on the assimilation rate were studied. Experiments were made in two series in which the salinities below 37 % 0 S were performed by diluting sea water with distilled water or with fresh spring water. In all investigated algae net oxygen production increased in the salinity concentrations which were prepared by düuting sea water with fresh spring water. In dilutions performed with distilled water, the oxygen production was depressed by all concentrations. Parallel with lower temperatures and lower salinities, usually low or even negative net production resulted. In general, the fresh spring water of high alkalinity (6.70 milliequivalents/1) and large amount of nutrients (reactive phosphorus 1.12 Mgat/1 and nitrates 27 jjg-at/l) when mixing with sea water, especially during low tide, caused incieased photosynthesis in algae, in comparison with that of normal salinity.

“…Gordon et al (1980) used 200 mg I" 1 NaHCO 3 as a supplement in the preparation of different salinities for a study of salinity tolerance in the green alga Cladophora albida (Huds.) Hammer (1969) demonstrated that chloride ions can be replaced by available bicarbonate ions in the 'apparent free space' of seaweeds and this may account for sustained photosynthesis at low salinities. They demonstrated some suppression of photosynthesis at 0.2 and 60%o but little effect over the range 10 to 40%o.…”

The growth rates of germlings of the large, introduced, brown alga Sargassum muticum (Yendo) Fensholt, collected from Bembridge, Isle of Wight, south coast of England, are described under different conditions of temperature, irradiance and salinity. The germlings showed a broad tolerance to all three environmental parameters, with growth recorded from 10 to 30 °C, 9 to 175 μΕ m" 2 s" 1 (500 to 10000 lux) and 6.8 to 34%o salinity; optimum growth occurred at 25 °C, 44 μΕ m"" 2 s' 1 (2500 lux) and 34%o salinity. These results are discussed in relation to aspects of the present and future ecology and geographical distribution of this invasive alga.Fundamental to the success and spread of Sargassum muticum in the North Atlantic and beyond is its ability to tolerate and respond to environmental parameters. In this respect probably the most vulnerable growth stage in the life history are the young germlings. To date germling growth rates in relation to controlled physical factors have only been investigated in the Sargassum species S. echinocarpum J. Agardh, S. obtusifolium J. Agardh, S. oligocystum Montagne, S. polyphyttum J. Agardh (De Wreede 1976, 1978 and Pacific populations of S. muticum (Norton 1977). In the present paper results are presented of an investigation into the effect of temperature, irradiance and salinity on European S. muticum germlings. Materials and MethodsDetails of the three germling growth studies are listed in Table I. Healthy fertile plants were taken from the mouth of Langstone Harbour, Hampshire and cultured at 20 °C under continuous light until multicellular germlings were released. These germlings were stored in a 10 °C growth room at 50 μΕ m" 28 " 1 with Botanica Marina / Vol. 32 / 1989 / Fasc. 2
