Resumen:
Understanding the causes and consequences of specialization in species interactions iscentral to ecology and evolutionary biology. This knowledge is important because specializationmay have profound ecological and evolutionary consequences (Brown 1984; Thompson 1994;Waser et al. 1996; Vázquez and Simberloff 2002). A primary question is how commonspecialization (or generalization) is in nature. Plant-pollinator interactions have been frequentlyregarded as tightly coevolved and highly specialized, with a general evolutionary trend towardsincreased specialization (Waser, Chapter 1, this Volume). But the extent to which suchspecialization actually occurs in most, or even some, of the species in a given community hasbeen recently questioned (Ollerton 1996; Waser et al. 1996).
