oligotroph

(noun)

An organism capable of living in an environment that offers very low levels of nutrients.

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.
