Cyclomorphosis

from Wikipedia, the free encyclopedia

The cyclones or cyclomorphosis even Temporalvariation or temporal change of form, describes the cyclical seasonal change in the morphology of organisms, especially the change of planktonic organisms such as water fleas , rotifers and other zooplankton . The name was coined in 1898 by the ecologist Robert Lauterborn , since then the phenomenon has been considered by numerous scientists, including the limnologists George Evelyn Hutchinson and Winfried Lampert .

The change in morphology mainly affects the length of various body appendages such as spines or, in the case of daphnia, the shape of the head and is probably induced by various factors that are effective during embryonic development, such as temperature, food availability, or the presence of potential predators .
