Edge Effect - Types

Types

  • Inherent- long term natural features underline adjoining vegetation, they are stable and permanent
  • Induced- from natural disturbances or human related activities, they are subject to successional changes over time
  • Narrow- straight, sharp, abrupt (forest and agricultural field)
  • Wide (ecotone)- distance between border and point where physical conditions and vegetation do not differ from interior of patch
  • Convoluted- has curves, not a straight line
  • Perforated- not a solid border, has gaps

Height can create borders between patches as well.

Famous quotes containing the word types:

    He types his laboured column—weary drudge!
    Senile fudge and solemn:
    Spare, editor, to condemn
    These dry leaves of his autumn.
    Robertson Davies (b. 1913)

    As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.
    Saul Bellow (b. 1915)

    The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.
    Anton Pavlovich Chekhov (1860–1904)
