2: A classic on biological invasions
This is a classic work (originally published in 1958) by the British scientist, Charles Elton. It is a must read for those who are interested in the field of bioinvasions, even if modern researchers do not agree with every point Elton made.
Elton gives examples of species that have been transported from one part of the world to another, sometimes becoming established pests. He shows how biogeographic areas may start to blend in, if not be lost, if biological invasions occur continuously.
Another issue Elton looks at is the use of pesticides and the resulting resistant strains of the pests the chemicals were meant to eliminate or control.
In the end, Elton calls for conservation - a co-existance between humankind and nature, and ecological variety.
