Ponds and Pools
Ponds are small bodies of water, usually much wider than they are deep, and usually containing self-organizing ecosystems. Ponds have been called microcosms by many writers in literature, such as Thoreau in his description of Walden pond in Massachusetts. Forbes (1887) and Hutchinson (1964) called ponds microcosms in the scientific sense of being a miniature demonstration of the processes occurring on a larger scale in lakes and oceans. In our terminology, most ponds are actually mesocosms, being larger than the small experimental laboratory microcosms.
