An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species ...
Large-leaved lupine (Lupinus polyphyllus): native to western North America but introduced and invasive in several areas worldwideIn biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. [1]
Many terms are used to describe the new range, such as non-native, naturalized, introduced, transplanted, invasive, or colonized range. [3] Introduced typically means that a species has been transported by humans (intentionally or accidentally) across a major geographical barrier. [4]
An introduced species that can spread faster than natives can outcompete native species for food, squeezing them out. Nitrogen and phosphorus are often the limiting factors in these situations. [17] Every species occupies an ecological niche in its native ecosystem; some species fill large and varied roles, while others are highly specialized.
Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. [1]
Native plants are plants that have been growing for thousands of years or longer in particular regions on land and in the sea, without being introduced by humans. Native plants support pollinators ...
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Enemy release may be weaker, too, when an exotic species is more closely related to native species in their introduced ranges, making them more likely to share herbivores or pathogens. [22] In a meta-analysis of 19 research studies involving 72 pairs of native and invasive plants, invasive exotic species did not incur less damage than their ...
