oligotroph

Examples of oligotroph in the following topics:

• Oligotrophs

  • Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density.
  • An oligotroph is an organism that thrives in an environment that offers very low levels of nutrients.
  • Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density.
  • An ecosystem or environment is said to be oligotrophic if it offers little to sustain life.
  • An example of oligotrophic bacterium are Caulobacter crescentus.

• Prochlorophytes

  • Picoplankton are responsible for the majority of the primary productivity in oligotrophic gyres, and are different from nanoplankton and microplankton.
  • These oligotrophic organisms are abundant in nutrient-poor tropical waters and use a unique photosynthetic pigment, divinyl-chlorophyll, to absorb light and acquire energy.

• Sea Coral and Sea Anemone Zooxanthellae

  • Cnidarians that are associated with Symbiodinium occur mostly in warm oligotrophic (nutrient-poor) marine environments where they are often the dominant constituents of benthic communities.

• Morphologically Unusual Proteobacteria

  • One notable group of prosthecates is the genus Caulobacter crescentus, a Gram-negative, oligotrophic bacterium widely distributed in fresh water lakes and streams .

• Planktonic Food Webs

  • On a broad scale, growth of phytoplankton in the oligotrophic tropical and subtropical gyres is generally limited by nutrient supply, while light often limits phytoplankton growth in subarctic gyres.

• Caulobacter Differentiation

  • Caulobacter crescentus is a Gram-negative, oligotrophic bacterium widely distributed in fresh water lakes and streams.

• Planktonic Communities

  • On a broad scale, growth of phytoplankton in the oligotrophic tropical and subtropical gyres is generally limited by nutrient supply, while light often limits phytoplankton growth in subarctic gyres.
