Eksempler på phytoplankton

• It is also possible that many freshwater phytoplankton groups had yet to evolve.

• They explain the link between nutrient recycling efficiency and surface nutrient concentration in terms of consumption by phytoplankton, iron supply, light limitation and temperature.

• In addition, a phytoplankton decline would carry marked consequences for phytoplankton's role in the global carbon cycle.

• Interrelated influence of iron, light and cell size on marine phytoplankton growth.

• The distributions of peak areas of phytoplankton biomass and krill were patchy.

• Eutrophic or nutrient-rich marine environments are often characterized by a high primary productivity of phytoplankton.

• Its dilution effect stabilises the water column, increases the retention of nutrients washed off the islands and leads to periodic phytoplankton blooms.

• The geographical extent of this biotope varied, dependent upon the efficiency of local upwelling conditions to provide nutrients for phytoplankton.

• Other contributing factors may be a reduction in light due to greater phytoplankton in the -oodwater and possibly epiphytic algal growth on the submerged leaves.

• They highlight the submergence of breeding colonies under raised sea levels, and also the reduction in phytoplankton populations as a consequence of warmer sea temperatures.

• This supports the relatively rapid change in the taxonomic composition of phytoplankton caused by fluctuations of the chemocline.

• The two northern lagoons tend to suffer from increasing nutrient loading and so have dense phytoplankton.

• Increasing radiation slows the process of photosynthesis in phytoplankton in the oceans' surface layers.

• The approach involves comparison with modern lake systems and phytoplankton productivity.

• They were part of a complex trophic web of the time including primary producers (phytoplankton) and primary to tertiary consumers (zooplankton and filterfeeders, suspension and deposit feeders, and invertebrate predators).
