Biological Filter Pond

This concise yet comprehensive introduction to the biology of standing waters (lakes and ponds) combines traditional limnology with current ecological and evolutionary theory. It integrates the effects of abiotic constraints and biotic interactions at both the population and community level, allowing the reader to understand how the distribution and success of different organisms in this freshwater habitat can be explained and predicted. The book is focused on temperate lakes and ponds, drawing on examples from polar and tropical systems to provide a broader context. The Biology of Lakes and Ponds, now in its second edition, will be a valuable text for university tuition. However, its lucid explanations and descriptions of adaptation, dominance, dispersal, and succession of organisms, as well as the effects of abiotic factors, predation, and competition, ensure its relevance and use to a broad audience of biologists and naturalists with an interest in freshwater ecology.

Schmutzdecke - Schmutzdecke (German, "grime or filth cover", sometimes incorrectly spelt Schmutzedecke) is a complex biological layer formed on the surface of slow sand filter beds. The Schmutzdecke is the layer that provides the effective purification in potable water treatment, the underlying sand providing the support medium for this biological treatment layer.

Graduated neutral density filter - A graduated neutral density filter, also known as a graduated ND filter, split neutral density filter, or just a graduated filter, is an optical filter that has a variable light transmision. Typically half of the filter is of neutral density which transitions, either hardly or softly, into the other half which is clear.

Lamellae (zoology) - Lamellae are gill-shaped structures: fine sheets of material held near one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding, the traction surfaces of geckos, and chloroplast membranes where high permeability is important.

Aerated lagoon - An aerated lagoon is a holding and/or treatment pond that speeds up the natural process of biological decomposition of organic waste by stimulating the growth and activity of bacteria that degrade organic waste.
