Shape Correction Function

The shape correction function is a ratio of the surface area of a growing organism and that of an isomorph as function of the volume. The shape of the isomorph is taken to be equal to that of the organism for a given reference volume, so for that particular volume the surface areas are also equal and the shape correction function has value one.

For volume, reference volume, the shape correction function equals for

  • V0-morphs:
  • V1-morphs:
  • isomorphs:
  • static mixtures between a V0- and a V1-morph: for

The shape correction function is used in the Dynamic Energy Budget theory to convert the equations for isomorphs to that for organisms that change in shape during growth. The conversion is necessary for food (substrate) acquisition and mobilization of reserve for use by metabolism.

Famous quotes containing the words shape, correction and/or function:

    The poet will prevail to be popular in spite of his faults, and in spite of his beauties too. He will hit the nail on the head, and we shall not know the shape of his hammer. He makes us free of his hearth and heart, which is greater than to offer one the freedom of a city.
    Henry David Thoreau (1817–1862)

    Shakespeare, with an improved education and in a more enlightened age, might easily have attained the purity and correction of Racine; but nothing leads one to suppose that Racine in a barbarous age would have attained the grandeur, force and nature of Shakespeare.
    Horace Walpole (1717–1797)

    Think of the tools in a tool-box: there is a hammer, pliers, a saw, a screwdriver, a rule, a glue-pot, nails and screws.—The function of words are as diverse as the functions of these objects.
    Ludwig Wittgenstein (1889–1951)
