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]
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.
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 ...

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 ...
In southern Europe, the scarcity of rabbits threatens the conservation of endangered predator species higher up the food chain, that depend on small game such as rabbits. These include the Iberian lynx and the Iberian imperial eagle. For this reason, biological warfare against rabbits in Australia is a serious concern for conservation ...
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.
Climate change is likely to favour some invasive species and harm others, [3] but few authors have identified specific consequences of climate change for invasive species. [4] As early as 1993, a climate/invasive species interaction was speculated for the alien tree species Maesopsis eminii that spread in the East Usambara mountain forests ...
