Oligotroph - Wikipedia
An oligotroph is an organism that can live in an environment that offers very low levels of nutrients. They may be contrasted with copiotrophs, which prefer nutritionally rich environments. Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density.
Oligotrophy - an overview | ScienceDirect Topics
Oligotrophy is defined as the ability of microbes to grow when concentrations of nutrients are very low or absent. Although oligotrophy generally has been considered the domain of prokaryotes, sufficient evidence is available to support the idea that fungi also can grow oligotrophically (Wainwright 1993).
What Are Oligotrophic, Mesotrophic, And Eutrophic Lakes?
2017年4月25日 · Oligotrophic: An oligotrophic lake or water body is one which has a relatively low productivity due to the low nutrient content in the lake. The waters of these lakes are usually quite clear due to the limited growth of algae in the lake. The …

Oligotroph - an overview | ScienceDirect Topics
Small (<3 μm) single-celled picocyanobacteria, most notably of the genera Prochlorococcus and Synechococcus, dominate vast expanses of the global oceans and often constitute ∼25% of oceanic photosynthetic production and biomass (Flombaum et al., 2013; Mann and Clokie, 2012).
What Are Oligotrophic Ecosystems: Characteristics and Significance
2024年1月30日 · Oligotrophic ecosystems are characterized by low nutrient levels, particularly nitrogen and phosphorus, which limit the growth of aquatic plants and algae. They often occur in environments where nutrient input is minimal, such as deep lakes or clear, open oceans.

2005年5月12日 · Oligotrophy, the obligate or facultative capacity to live in low-nutrient habitats, has played a major role in the evolution of photosynthetic organisms. Energy/carbon deficiency: evolution of photosynthesis about 3.5 Gyr (billion years) ago, then use of H 2 O as electron donor, and accumulation of O 2 from about 2.3 Gyr ago.
