The answer is blowing in the wind


Figure 1
Plants that colonize new and/or transient habitats may find themselves ‘out on their own’ with very few individuals of the same species in the vicinity. Opportunities for outbreeding are then very restricted and it is therefore not surprising that many colonizing and pioneer species are self-fertile. Indeed, so common is this correlation that it is often assumed that all such species are mainly inbreeders. However, it is dangerous to make unsupported assumptions of this kind, as nicely shown by Friedman and Barrett (Toronto, Canada, pp. 1303–1309) in respect of the North American annual Ambrosia artemisiifolia. The authors' experiments were models of efficiency and clarity. Firstly, they grew plants in arrays of differing densities. Planting density had some effect on the amount of pollen received: plants . . . [Full Text of this Article]
