Seedlings that were once removed by ecological selection now become favored, because the shaded forest floor has become ideal for such shade tolerant species.

Partial shading stunts its growth, and significant shading can eliminate it in the long term by reducing its ability to compete with more shade-tolerant species.
43.
The characteristic maritime-like forest occurring on the perimeter of Callawassie Island is composed of live oak and salt-tolerant species such as loblolly pine and palmetto.
44.
It is the most cold-tolerant species of eucalyptus, with " E . pauciflora " subsp . " niphophila " surviving temperatures down to and year-round frosts.
45.
It is by far the most cold-tolerant species in the Meliaceae and the only member of the family that can be cultivated successfully in northern Europe.
46.
Furthermore, although these species often dominate immediately following a disturbance, they are unable to compete with shade-tolerant species later on and replaced by these species through succession.
47.
Since both Western Hemlock and Western Redcedar are shade tolerant species, a basal area of is recommended and would be the maximum basal area the stand could support.
48.
A Douglas-fir stand may grow for centuries without disturbance while an old-growth ponderosa pine forest requires frequent surface fires to reduce the shade-tolerant species and regenerate the canopy species.
49.
Non-pioneer heliophilic ( sun-loving ) tree species then add to the biomass and species richness as well as shade tolerant species and this can last 75 to 150 years.
50.
Pemberton's deer mouse is a very cold-tolerant species; they live and survive in temperatures between 22 and 25 �C . They are usually sexually mature by 55 days of age.
