Aquariattoral zones of larger bodies. Aquaria were the microcosm type first set up by Robert Warrington (Chapter 8). If one counts the aquaria in schoolrooms around the world and in the homes of hobbyists, probably millions of these microcosms have been set up, but relatively few have been seriously studied.

osteoclasts

Ponds and Poolsonds 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.

ASSET

Reefs and Benthic Microcosmsream microcosms where the water flow is unidirectional. This chapter concerns microcosms which mimic the reefs, bottom communities, and encrusting ecosystems in lakes and seas where water motions are multidirectional.

Reflections on the Human Experience of Joy whole, simplified ecosystems, and because they can be replicated for experimental studies at reasonable cost. This book is a review of the extensive but scattered papers and reports on microcosms, with emphasis on the concepts of systems ecology that emerge from the hypotheses and experimental tests.

Metabolism and Homeostasis consider in Chapter 2 the metabolic basis of microecosystems. The main processes are photosynthetic production, consumption, and the recycling of nutrients. Oxygen and carbon dioxide are produced, consumed, and exchanged with the atmosphere. Organic biomass is produced, accumulated, or used up, dep

策略

Succession and Self-organization These processes occur in microcosms, often rapidly, when the components are small with short turnover time. What actually occurs depends on the initial seeding of matter and available species. On a longer scale of time, the mature states which follow initial growth may oscillate, alternating produc
