<span>Populations of algae and the animals that feed on them are lower in oligotrophic lakes because of low nutrient concentrations. Thus the water remains clear. The decay of the relatively small amount of organic matter in oligotrophic lakes does not completely deplete the hypolimnetic supply of dissolved oxygen. Therefore, lack of oxygen does not restrict animals from living in the hypolimnion of oligotrophic lakes. Lake trout, for example, require cold, well-oxygenated water and primarily live in the hypolimnion of oligotrophic lakes. Minnesota's oligotrophic lakes are found in the northeast region of the state, where infertile soils are covered with mixed conifer forests.</span>

In the Claritin commercial, the man is laying in the grass with a
beagle puppy. The beagle is a breed of small hound that is similar to a larger
foxhound that has approximately
220 million scent receptors. This is the reason why they are employed as
detection dog and not as guard dogs for they are usually friendly dogs.
