Species Accounts - Overview
The problem of non-native species has been rated the second most important threat to biodiversity, after habitat destruction by humans, according to the IUCN. There is no doubt that many introductions have resulted in disasters and unwelcome homogenization of so many valuable ecosystems that altogether works to maintain a diversified, multi-functional world of life with intrinsic, practical and aesthetic values.
Human have been such a successful vector of exotic organisms that the populations of many of our commensals have become globalized, and there are no countries that could be exempt from the adverse effects of the phenomenal immigration of these organisms. Many cities are now invested with Pigeons whose excrement pollute the cityscape; outbreaks of mice were not uncommon at the turn of the last century, and the silent onslaught of garden birds, depleted fish stock in lakes, patches of noxious weeds choking out other plants and the familiar fauna of urban areas in Honolulu are just a few examples of the increasingly discernible presages of more serious effects of ecological imbalance as the new millennium shines through the clouds to find us amidst the most disastrous of acute environmental catastrophes in millions of years.
We will present a selection of the most influential NNS in this section to give a picture of what the situation is like and how the invasion is getting on. The species portrayed in this section are the soldiers of an army stampeding across the world, having crossed the gangway of vessels we have captained onto uncharted territory of milk and honey. Representative species from all major vertebrate groups feature in these profiles, as well as other less conspicuous species, which nevertheless contribute to no less disastrous effects than the 'mega fauna' of the present day --- humans, who had had them teleported to the wrong universe in the first place.
