- The relationship between gas transfer velocity and wind speed was evaluated at low wind speeds by quantifying the rate of evasion of the deliberate tracer, SF 6, from a small oligotrophic lake.
- Trophic means concerned with nutrition, and oligotrophic lakes are poorly fed; that is, they have a low concentration of nutrient elements such as nitrogen and phosphorus.
- Altogether, this indicates that sestonic components of autochthonous origin should be closer to Redfield proportions in eutrophic than in oligotrophic lakes.

- Given the dearth of nutrients in their environment, these oligotrophic bacteria must generate their energy from a variety of sources.
- A coupled algae - bacteria relationship mediated by C released from algae was observed during a 2-yr period in an oligotrophic high mountain lake, except at upper depths.
- It is interesting that they found a lower incidence of food limitation in K. cochlearis from an oligotrophic lake than we found in a eutrophic pond which presumably had a higher total biomass of phytoplankton.
- We examined long-term phytoplankton data records for four oligotrophic boreal lakes situated in the Experimental Lakes Area, western Ontario, for responses to climatic change.
- Median photosynthetic parameters observed with the oxygen method were up to twice as high as those measured with 14 C in other oligotrophic Shield lakes.
- Model predictions of downwelling spectral irradiance distributions in seagrass canopies growing in both oligotrophic and eutrophic waters were within 15% of field measurements.
- Redberry Lake, an oligotrophic saline lake in central Saskatchewan, is located in a hydrologically closed basin and has high levels of DOC.

noun ˌɒlɪˈɡɒtrəfi

Ecology

This production increase suggests that a shift in the trophic status of the river from oligotrophy to eutrophy accompanied development of New Bedford's commercial economy.
Example sentencesExamples
- Oligotrophy, the obligate or facultative capacity to live in low-nutrient habitats, has played a major role in the evolution of photosynthetic organisms.
