Ecosphere

Ecosphere has several different meanings:

  • In ecology the term ecosphere can refer to the Earth's spheres, a planetary ecosystem consisting of the atmosphere, the geosphere (lithosphere), the hydrosphere, and the biosphere.
  • In astronomy an ecosphere is an imaginary shell of space surrounding stars where conditions are such that life might survive. See habitable zone.
  • Ecosphere (aquarium) is a water filled sealed glass ball containing living algae and shrimp in a stable miniature ecosystem.
  • Ecosphere is also the name of an open-access journal published by the Ecological Society of America
Ecosphere (aquarium)

The EcoSphere and "Original Ecosphere" are trademark names for sealed blown-glass miniature aquaria produced by Ecosphere Associates, Inc., of Tucson, Arizona, United States. Spherical or ovoid, the aquaria range from roughly baseball-size to soccer-ball-size. They are sold worldwide as scientific novelties and decorative objects.

The EcoSphere's main visual appeal is provided by tiny red-pink shrimp, Halocaridina rubra, between 1/4 and 3/8 inch (or approximately a centimeter) in length. The shrimp swim energetically around the aquarium, eat the brown bacterial and algal scum on the glass, consume the filamentous green algae which sometimes forms a globular pillow in the water, and perch on a fragment of soft coral.

The main conceptual interest of these objects lies in the fact that they are materially closed ecological systems which are self-sustaining over a period of years. At room temperature, and with only low inputs of light, the algae produce oxygen which supports the shrimp and bacteria. Bacteria break down the shrimps' wastes. The breakdown products provide nutrients to the algae and bacteria upon which the shrimp feed. The manufacturer states that shrimp live in the EcoSphere for an average of 2 to 3 years, and are known to live over 10 years.

A magnetic scrubber is enclosed in each EcoSphere. By passing another magnet over the outside of the glass, the owner can manipulate the scrubber to clean the inside of the EcoSphere.

Ecosphere (social enterprise)

Ecosphere is a social enterprise that works on the sustainable development of Spiti Valley, a cold mountain desert in the Trans- Himalayas of India, by focusing on economic empowerment, environmental conservation and community development.
