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.
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]

Where Do Camels Belong? is a book by biologist Ken Thompson. [1] [2] [3] [4]The book examines the science and history of invasive species.The book describes itself as "an examination of the whole question of native and alien species, and what might be called an alien invasions industry—and its implications".
When the characteristics of a non-native species and native species are significantly similar a single native species can go a long way to prevent the invasion of a non-native species. [ 8 ] A habitat with high species diversity results in lower total resource availability thus decreasing the success of an invader. [ 8 ]
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 ...
