“…Lock et al (1984) presented data for the underside of rock surfaces which are similar to the data for disks incubated in the dark in White Clay Creek. The 2.2-fold increase in Chl a on sediments in the light may be attributable, in part, to spatial heterogeneity of algal growth, but increases of a similar magnitude have been reported for coastal waters (Fuhrman et al 198 5), and generation times of -1 d have been reported for diatoms growing at 10°C (Hitchcock 1980). Algae transported and deposited from upstream blooms were probably the source of the high Chl a concentrations associated with dark sediments.…”

Diel fluctuations in stream water temperature and chemistry, microbial biomass, and bacterial activity were measured in White Clay Creek, Pennsylvania, during vernal algal blooms in three different years. DOC concentrations increased 24-37% over early morning minima and temperature increased nearly 10°C over a 7-10-h period. Total carbohydrates and monosaccharides exhibited irregular fluctuations with total carbohydrates showing concentration peaks in the morning and afternoon. Acetate concentrations were highest in midafternoon, while the concentration pattern for primary amines differed from the DOC pattern with highest values at midnight. No distinct diel patterns were found for streambed ATP, GTP : ATP, Chl a, and total or active bacteria, although significant year-to-year and between-habitat differences were observed. Bacterial activity, measured by phospholipid biosynthesis, total lipid biosynthesis, respiration, and incorporation of [3H]thymidine into DNA increased 1.4-fold to 3.0-fold from morning to afternoon. Microcosm experiments indicated that the activity of bacteria attached to sediments was more sensitive to increases in water temperature than to changes in water chemistry, whereas bacteria attached to porcelain disks responded to the influences of both temperature and water chemistry.

“…However, S. costatum is a eurythermal species consisting of many sub-strains (Sarno et al, 2007), growing at water temperatures from 2.0℃ to 30℃ (Hitchcock, 1980), strains appearing through the year off the coasts of Korea and Japan (Oh et al, 2008;Shikata et al, 2008;Park et al, 2009). Maximal growth rates of different strains are found between 20…”

We examined the combined impacts of future increases of CO2 and temperature on the growth of four marine diatoms (Skeletonema costatum, Chaetoceros debilis, Chaetoceros didymus, Thalassiosira nordenskioeldii). The four strains were incubated under four different conditions: present (pCO2: 400ppm, temperature: 20℃), acidification (pCO2: 1000ppm, temperature: 20℃), global warming (pCO2: 400ppm, temperature: 25℃), and greenhouse (pCO2: 1000ppm, temperature: 2 5℃) conditions. Under the condition of higher temperatures, growth of S. costatum was suppressed, while C. debilis showed enhanced growth. Both C. didymus and T. nodenskioldii showed similar growth rates under current and elevated temperature. None of the four species appeared affected in their cell growth by elevated CO2 concentrations. Chetoceros spp. showed increase of pH per unit fluorescence under elevated CO2 concentrations, but no difference in pH from that under current conditions was observed for either S. costatum or T. nodenskioeldii, implying that Chetoceros spp. can take up more CO2 per cell than the other two diatoms. Our results of cell growth and pH change per unit fluorescence suggest that both C. debilis and C. didymus are better adapted to future oceanic conditions of rising water temperature and CO2 than are S. costatum and T. nodenskioeldii.

“…Examples of photoadaptive parameters are: the in vivo fluorescence yield of chlorophyll a (Kiefer, 1973;Heaney, 1978;Vincent, 1979Vincent, , 1980Hanis, 1980b), the chemical composition of phytoplankton (Gibson, 1978;Laws and Bannister, 1980;Falkowski and Wirick, 1981), ratios of photosynthetic pigments (Brooks, 1964;Falkowski, 1980;Prezelin and Matlick, 1980), photosynthetic capacity (Steemann Nielsen and Hansen, 1959;Steemann Nielsen and Jorgensen, 1968;Beardall and Morris, 1976;Falkowski, 1981), and in the broad sense, algal growth rate (Jitts et al, 1964;Paasche, 1968;Beardall and Morris, 1976;Hitchcock, Table 1. Simulations of algal response to 1980).…”

In their natural environment, phytoplankton are exposed to fluctuations in incident irradiance due to vertical displacements in the water column induced by turbulent fluid motion. Physiological adaptation to these fluctuations results in variation in a number of measurable quantities (e.g. parameters of P-I curves, fluorescence yield, chemical composition), each of which have different time-scales of adaptation. A reaction-diffusion model is analyzed to determine the physical conditions under which a given physiological adaptation would be of ecological importance and thus may show variation in the photoadaptive variable with depth in a mixing layer. Two non-dimensional numbers control the dynamics. KJP2y expresses the ratio of the mixing rate to the photoadaptation rate (K, is the eddy diffusion coefficient, l' is the mixing length, and y is the photoadaptation rate constant for given variable). k,t' is the ratio of the mixing length scale to the optical length scale (k, is the attenuation coefficient for scalar irradiance). When KJP2y is low and k,P is high, photoadaptation proceeds fast enough to create variations in depth in the photoadaptive variable and conversely, when &/P&( is high and k,t' is low, turbulent fluid motion dissipates any depth variation. By observing the variation in depth of several photoadaptive variables, each with a different photoadaptation time-scale, the mixing rate of the water can be estimated. Data from laboratory and field experiments are used to illustrate applications.
