Unlike the notable ideas (concerning the success of invasive non-indigenous organisms) that preceded it, such as the enemy release hypothesis (ERH) and Charles Darwin's Habituation Hypothesis, [2] the EICA hypothesis postulates that an invasive species is not as fit (in its introduced habitat) at its moment of introduction as it is at the time that it is considered invasive.
The Invasive Species Compendium (ISC) is an online, open access reference work covering recognition, biology, distribution, impact, and management of invasive plants and animals produced by CAB International alongside an international consortium. [1] It comprises peer-reviewed datasheets, images, and maps, a bibliographic database, and full ...
A young cane toad. The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
Most exotic species do not become invasive, [7] and some authors suggest that those that do represent repeated and larger introductions that generate propagule pressure. [8] Among the many explanations for invasive success, however, the enemy release hypothesis has had the most support. [9]

Many of these, especially the tiger pear, quickly became widespread invasive species, rendering 40,000 km 2 (15,000 sq mi) of farming land unproductive. [2] The moth Cactoblastis cactorum from Argentina , whose larvae eat prickly pear, was introduced in 1925 and almost wiped out the prickly pear.
These are lists of invasive species by country or region. 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 ...
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
