Euryoecious and stenoecious

Euryoecious organisms are those which have a broad variety of ecological living conditions, regarding one single factor for example plants that grow both on wet and dry soils. An example are the pines, which in some areas grow on humid soils as well as on dry soils while on medium soils they are absent because other, more competitive trees dominate.

Stenoecious organisms on the other hand are quite limited in their conditions, for example plants that grow only on moist and acid soils in shaded positions.

Euryoecious organisms are principally more adaptable and less vulnerable than stenoecious ones.
