    Light-shade adaptation of Stylophora pistillata , a hermatypic coral from the Gulf of Eilat (1981)

    Notes: [Auszug] Specimens of S. pistillata, adapted to light and shade regimes, were collected from a remote reef near Nabq in the Sinai Peninsula (28.20° N, 034.95° E) and taken immediately to a lagoon near a shore-based laboratory. The corals were kept in shaded (10% incident light), submerged baskets in ...

    Effects of temperature and day length on the mass balance of Antarctic phytoplankton (1987)
    Springer
    Polar biology 7 (1987), S. 35-42

    Topics: Biology
    Notes: Summary Photosynthesis and respiratory carbon losses of freshly collected Antarctic phytoplankton were measured in incubators at 5 temperatures between-2° C and +8°C. The results were used to predict daily growth rates and to define temperature and daylength boundary conditions under which the net balance between photosynthesis and respiration would be positive and allow increases in standing stock. Whereas the Q10 of photosynthesis was 1.4–2.2, the Q10 of respiratory losses exhibited a wide range and higher maxima (2.3–12). Model calculations sugest that under ample light energy supply during long summer days, potential daily growth rates are not severely affected by the low temperatures prevailing in the Southern Ocean. If energy supply is restricted by short days and deep water column mixing, substantially reduced respiration rates at low temperatures may allow the algae to survive.

    Some aspects of the ecology of the desert snail Sphincterochila prophetarum in relation to energy and water flow (1981)
    Springer
    Oecologia 50 (1981), S. 103-108

    ISSN: 1432-1939

    Topics: Biology
    Notes: Summary Between 1976–1978, we studied the ecology of the Sphincterochila prophetarum, the most common snail, on stony slopes in Northern Negev. Energy and water flow determinations were made at the individual and population levels on a field observation basis and metabolic data were derived from laboratory simulations. The snails are active during 5–7% of the time during the year, while the remaining 95% of the time, the snails are in aestivation under stones. The energy and water inputs during the short feeding periods are very fast. Only 8% of the total energy in the eaten food are assimilated. Eighty-nine percent of the total assimilated energy are utilized in respiration during the various periods of activity and dormancy. The water loss during the feeding and activity period is about 37% of the total annual input. The snails lose twice as much the amount of water during the winter dormancy periods than in the summer dormancy period.
