/ˌænəˈbaɪəsɪs/

Definitions

• A state of suspended animation in which metabolic processes are temporarily stopped or slowed down, often in organisms capable of entering such states, like certain microorganisms or animals.
• The condition in which an organism, especially one under adverse environmental conditions, appears to be in a dormant state with minimal metabolic activity, awaiting more favorable conditions.

Usage Examples

• "The desert plant enters anabiosis during dry spells, awaiting rain to trigger its revival."
• "Certain microscopic organisms can survive extreme environments by entering a state of anabiosis."

Etymology

From Greek "ana-" (up, again) + "biosis" (mode of life), referring to a return to life or activity after a period of dormancy or suspended animation.

Synonyms

• Dormancy
• Suspended animation
• Hibernation

Antonyms

• Metabolic activity
• Life
• Revival

Translations

Regional Pronunciation Variations

• In some regions, the emphasis is placed on the first syllable: "ANA-biosis."
• In technical fields, the pronunciation may emphasize the second syllable: "a-NA-biosis."

Historical Usage

The term "anabiosis" was first coined in the early 19th century, as scientists began to explore the phenomenon of life forms entering states of dormancy or metabolic slowdown under extreme conditions. It has since been a central term in the study of extreme environmental conditions and biological survival strategies.

Cultural Nuances

While "anabiosis" is most commonly used in scientific contexts, it has metaphorical applications in literature and culture to describe periods of inactivity or stagnation, followed by a resurgence or awakening. The concept is sometimes linked to themes of resilience and recovery, especially in challenging circumstances.

More Information

Anabiosis is a biological state in which organisms suspend or dramatically reduce their metabolic activities in response to extreme environmental stress, such as drought, freezing, or lack of food. Some microorganisms, such as tardigrades, and certain plants and animals, like desert rodents, have evolved mechanisms for entering anabiosis, allowing them to survive until conditions improve.

This state is closely related to other forms of dormancy, such as hibernation and torpor, but differs in the degree and type of metabolic shutdown. Anabiosis is an important survival strategy for organisms in environments where fluctuating or extreme conditions prevail.
