摘要: When the barrier between biotas with long separate histories breaks down, species invade from one biota to other. Studies of episodes marine and terrestrial biotic interchange that have occurred during last 20 million years show large-scale extinction before onset renders especially prone invasion. As environments are being exploited eliminated on an ever increasing scale in human-dominated biosphere, geographical expansion which evolution high competitive, defensive, reproductive abilities has proceeded furthest will become more frequent. Historical events interactions essential ingredients for understanding current future structure composition world's biota.
