The Onslaught of Alien Species, and Other Challenges in the Coming Decades *

摘要: Abstract: Among the many environmental challenges faced by conservation scientists and managers in coming decades, inexorable invasion of alien species from distant land masses between heretofore isolated regions within continents may be most revolutionary. Although these invasions will homogenize impoverish world's biota, they lead to a deeper understanding ecological communities. One consequence current biotic interchange is that public's use outdoors continue decline as new pathogens parasites, their distributions survival enhanced climate warming other anthropogenic factors, reduce safety enjoyment hunting fishing hiking. The forthcoming massive disruptions are bound produce misunderstanding conflict among environmentalists. Attempts biologists manage wild feral animals, including vector species, blocked animal's rights groups. Even biology movement there real potential conflicts, especially over turf resources. Such conflicts serious threat biological diversity. Tolerance compromise essential if accomplish its mission.
