| Résumé : | Humans have been introducing species outside their native ranges as a source of food for thousands of years, but introductions of wildfowl have increased dramatically since the 1700s. The most serious consequence of this has been the extinction of endemic forms as a result of hybridisation, although competition between alien and native forms may also contribute to species loss. Globally, non-native wildfowl have yet to cause major disruption to ecosystem functions; introduce new diseases and parasites; cause anything other than local conflicts to agricultural and economic interests; or create major health and safety issues in ways that differ from native forms. The fact that this has not happened is probably simply the result of good fortune, however, since many introduced plants and animals have had huge consequences for ecosystems and human populations. The potential cost of greater environmental and economic damage, species extinction, and threats to the genetic and species diversity of native faunas means that we must do all we can to stop the deliberate or accidental introduction of species outside their natural range. International legislation to ensure this is remarkably good, but domestic law is generally weak, as is the political will to enforce such regulations. The case of the Ruddy Duck Oxyura jamoicensis in Europe will show whether control of a problem taxon can be achieved and underlines the financial consequences of dealing with introduced aliens. This paper was originally presented as the 58th Bernard Tucker Memorial Lecture to the Oxford Ornithological Society and the Ashmolean Natural History Society, in November 2008. |
