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.
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 native counterparts and, in fact, exhibited lower relative growth rates. [23] In other cases, invasive success was due not to release from herbivory but greater tolerance of it. [24]
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 ...
Cane Toads: An Unnatural History is a 1988 documentary film about the introduction of cane toads to Australia. Cane toads were introduced to Australia with the aim of controlling a sugar cane pest, the cane beetle, but they over-multiplied and became a serious problem in the Australian ecosystem.

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.

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 range of the common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture and human interests.
