The flux rates were determined on sediment from different water depths ... and primary production and compare their production with that of other primary producers (e.g. phytoplankton, sea ice algae, coralline algae, and benthic macrophytes
Typical O2 productionrates for vegetation are between 30-220 g/m2 per day, therefore an area between 5 and 30 m2 is required (Eckart 1996). This area ... produces. Algae are responsible for 90% of the photosynthetic production of O2

Larkum (1983) proposes that 8 g C m-2 d-l is the maximum sustainable limit to net primary production on coral reefs ...

is below limiting level. By ratio N/Р in algae tissues it can be inferred by possible limitation of their photosynthesis or growth rate. So, on several species of green, brown ... . On the basis of measurements of algaeproduction parameters and the ratio N/Р ... Table 1.

experience an algal “bloom” – a large production of the microscopic plants, called algae, which float suspended in the water and give it its green color. Photosynthesis from algae ... this excessive amount of algae pumps a lot of oxygen into the water via photosynthesis
and bicarbonate is likely to limit the rate of photosynthesis (e.g., Larkum et al. 2003). Both ... photosynthesisrates (Figs. 3 and 4). The stationary phase cultures of Nitzschia ovalis (Fig. 3) were an exception, where respiration rate in darkness was ;60% of net photosynthesisrate at 105
no evidence that competitive interactions decoupled algal and bacterial production ... between epiphytic algae and bacteria also is consistent with results of other studies ... of nutrients into epilithon is the most likely rate-limiting step in nutrient transfer
