Plant and Animal Species Spread

As a result of the globalization of trade and transport, in the past decades, tens of thousands of species have spread into regions where they were not originally at home. Potentially serious consequences of this include the displacement or extinction of native species and the spread of health risks. Even though trade flows are known to represent an important path for the introduction of invasive species, this fact alone is not enough to explain the observed distribution patterns of species.

In order to study this apparent contradiction, a team developed a computer model that combines the international trade flows with the species' worldwide distribution. The model shows that short distances of less than 3,000 kilometres primarily serve the transport of species that already occur in the target country. On the other hand, non-native species are usually introduced over comparatively much longer distances.

Here, the global patterns of the species' spread closely mirror the global trade flows. However, this only holds true when a species conquers new ground for the first time. Once an exotic species has gained a foothold outside its region of origin, it can also spread to new areas over short distances.

The manner in which these 'new settlers' spread to new areas differs between various groups of plants and animals. Mammals, reptiles and fishes, in particular, often spread over rather short distances (3,000 kilometres). Plants and birds tend to invade regions at a much greater distance

"The spread of non-native species is a complex process, and the data situation is far from complete. Therefore, it is even more astonishing that the spread can be explained with simple models," says Prof. Dr. Bernd Blasius of the Institute for Marine Chemistry and Biology (ICBM) at the University of Oldenburg.

------ "This gives us reason to hope that in the future, the introduction of exotic species can be better understood, and more efficiently controlled, with the aid of such models!
