Active and passive dispersal

Like most biological categories, the distinction between active and passive dispersers is blurred at the edges. Passive dispersal in air currents, for example, is not restricted to plants. Young spiders that climb to high places and then release a gossamer thread that carries them on the wind are then passively at the mercy of air currents; i.e. 'starting' is active but moving itself is effectively passive. Even the wings of insects are often simply aids to what is effectively passive movement (Figure 6.1).
