| In two oligotrophic lakes, calanoid copepods ingested HNF at biomass-specific rates that were 2.2 times higher than those of cladocerans. |
|
| Given the dearth of nutrients in their environment, these oligotrophic bacteria must generate their energy from a variety of sources. |
|
| The centers of a raised bog consist of oligotrophic peat, the best quality fuel, not polluted by mineral substances such as clay or sand. |
|
| Chestnut trees, birch trees, holly bushes and alder buckthorns in oligotrophic oak groves. |
|
| For males and females, much of the relationship was driven by the values for Lake Woodruff, the only oligotrophic lake. |
|
| Relatively cool summer temperatures and the oligotrophic conditions found in Lake Duhamel are conducive to whitefish development. |
|
| The limits of oligotrophic and eutrophic conditions have been set in terms of the rate at which oxygen is depleted from the hypolimnion. |
|
| In coastal marine waters, cyanobacteria are, conversely, responsible for most primary production in numerous oligotrophic environments. |
|
| This result is a paradox given the marked oligotrophic nature of the Mediterranean. |
|
| Particularly in temperate zones, such conditions favour a plentiful oxygen content, and the lake is said to be oligotrophic. |
|
| Misty lake is deeply stained, oligotrophic, and dense plant growths occur in the summer. |
|
| One such classification identifies two types of lakes: oligotrophic and eutrophic. |
|
| 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. |
|
| An aquatic environment rich in phosphorus is considered to be eutrophic, whereas a phosphorus-poor area is considered oligotrophic. |
|
| The Lake was originally an oligotrophic water body with hydrocarbonate-calcium ionic content, very low turbidity, and low concentrations of microelements. |
|
| Rainbow trout was collected in lakes of all sizes, depths, and elevations, ranging from low to high levels of lake disturbance and relatively oligotrophic to eutrophic waters. |
|
| Altogether, this indicates that sestonic components of autochthonous origin should be closer to Redfield proportions in eutrophic than in oligotrophic lakes. |
|
| 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. |
|
| Aquatic systems may change from oligotrophic to eutrophic, or the rate of eutrophication of a natural eutrophic system may be accelerated by the addition of nutrients and organic matter due to human activities. |
|
| To the contrary, didymo thrives in oligotrophic, or low-nutrient, waters. |
|
|
|
| Caribbean waters are relatively oligotrophic. |
|
| He continued his studies at McGill University in Montreal, where he examined the effects of fertilization on the nutrient status and food web of an oligotrophic wetland in central Manitoba. |
|
| Changes in algal community structure following zebra mussel invasion of an oligotrophic inland lake. |
|
| These habitats include shallow rain-fed seasonal pools and oligotrophic lacustrine habitats. |
|
| On the phytosociology and ecology of Isoetes asiatica Makino in oligotrophic water bodies of South Sakhalin. |
|
| This may be seen as a mismatch between water chemistry and water biology with a tendency for the biological component to be more oligotrophic than the chemistry would suggest. |
|
| Briefly, Florida Bay is subtropical and is generally oligotrophic. |
