The gradient is used subse quently as an strength resource to force the uptake of metabolic substrates in polar epithelial cells and to exploit it for reasons of communications in excitable cells.

Or, and this is more likely at present, it could be that lightly burned fires, which remove the canopy and create hotter and more luminous conditions at ground level, are not very different - from the plant's perspective - from other disturbances producing the same effect. In this latter case, quilo and tevo would merely be colonizers favored under disturbances large enough to produce the hot ground conditions, as simulated by Munoz and Fuentes (1989) in the laboratory and by the light burning fires reported by Segura et al.
We found that herbs may play a role in the survival of seedlings of Adenostoma, but in different way than suspected. Removing herbs tended to decrease the survival of Adenostoma seedlings whereas it hardly changed that of Ceanothus at all .
