Application of insular biogeography theory to conservation biology. Virgin forest: old growth forest, primary forest (cid:498)climax vegetation(cid:499) Secondary growth: plants that have come in since the disturbance. Succession: primary, colonization on a surface that has never been colonized before, volcanic, secondary, new vegetation that grows on surfaces that have had colonization before, processes include gradual increases in stature and complexity, pioneer species, (cid:498)climax communities(cid:499): Introduced intentionally or unintentionally by human: animal, plant, microbe, etc venomous, preys on native lizards, birds; power outages large flocks displaces native species, damages crops.
