  • n. An abrupt and marked variation in the condition or appearance of a species; a sudden modification which may give rise to new races.

from The Century Dictionary and Cyclopedia

  • n. Saltatory action; the act or movement of leaping, or effecting a saltus; a leap or jump; hence, abrupt transition or change.
  • n. Jumping movement; beating or palpitation.
  • n.
  • n. The name ‘saltation,’ or in recent years ‘mutation, has been applied to extreme fluctuation, the immediate cause of which is unknown. The experiments of Dr. Hugo de Vries on the saltations of the descendants of an American form of evening primrose (Œnothera lamarckiana) have recently drawn general attention again to the possibility that saltation has had a large part in the process of formation of species.

  • "A recent study finds that saltating sand particles induces a static electric field by friction. Saltating sand acquires a negative charge relative to the ground which in turn loosens more sand particles which then begin saltating. This process has been found to double the number of particles predicted by previous theory. This is significant in meteorology because it is primarily the saltation of sand particles which dislodges smaller dust particles into the atmosphere. Dust particles and other aerosols such as soot affect the amount of sunlight received by the atmosphere and earth, and are nuclei for condensation of the water vapour."
