title: Determining the effects of introduced species.
abstract: People have moved species around the world for millenia, sometimes by accident, but often with considerable enthusiasm. English garden birds in New Zealand are merely quaint curiosities introduced by settlers wanting the familiar species of their former homes. Some introductions have been devastating - goats or rabbits on various islands, for example. Other introductions, such as those of genetically engineered organisms, present potential problems yet to be considered in any detail. What should we expect the impact of introduced species to be?
