1. Physical and chemical characteristics of three acidic oligotrophic lakes and their watersheds in Kejimkujik Park, Nova Scotia.

2. Comparison with data from other studies confirms the predictive utility of water alkalinity for estimating Cd accumulation in fish from oligotrophic lakes.

3. Station Aloha was established in 1988 at the start of A Long-term Oligotrophic Habitat Assessment (Aloha) and this assessment continues today in many forms.

4. Its depth provides the only Bathypelagic (> 1000 m deep) freshwater habitat on Earth and its oxic, ultra‐oligotrophic features make it a freshwater counterpart of the deep ocean.

5. To study the biogeochemical cycle of phosphorus, it is very important to accurately determine the concentration of orthophosphates in the surface of oceans, especially oligotrophic open-oceans.

6. This is because macrofauna from abyssal sediments, especially in oligotrophic and mesotrophic areas, is generally much smaller than macrofauna found in eutrophic abyssal sediments and in shallower water.

7. Plankton (larger than 76 micrometers) taken from an undisturbed oligotrophic was found to have δ13 C values (=13/12 C relative to the Pee Dee be- Belemnite standard) rangingfrom –44 to –47 per mil

8. Biotopes, etc ; Oscillatoriales; biogeography; genes; new species; phylogeny; ribosomal RNA; Show all 7 Subjects Abstract: A population of Desertifilum (Cyanobacteria, Oscillatoriales) from an oligotrophic desertic biotope was isolated and characterized using a polyphasic approach including molecular, morphological, and ecological information.
