| Tóm tắt: | Significant problems with invasive alien species are a relatively recent phenomenon.
In most parts of the world, the biggest impacts have been felt only
in the last 50 years. There are some prominent examples of widespread invasions,
presumably with impacts (although in most cases we have little or no
information on this) that date back much further. For instance, Charles Darwin
wrote of invasive populations of the alien milk thistle, Silybum marianum, and
cardoon, Cynara cardunculus, covering square kilometres in Argentina in
1833. Countless species were added to lists of invasive aliens in the 20th
century and for every region for which accurate data are available, the
numbers of species at every stage of the introduction–invasion continuum are
increasing. More worrisome invaders, more biodiversity affected and everincreasing
complexities for those tasked with the management of natural and
semi-natural ecosystems. |
