Resumen:
1Although reproductive success of pollination specialist plants has been predicted tobe more sensitive to habitat fragmentation than that of generalist plants, recent resultsindicate that effects do not differ between plants with different degrees of specialization.2We provide an explanation for such unexpected results by linking evidence thatspecialization of plant?pollinator interactions is asymmetric to observations thatgeneralist pollinators are less affected by habitat fragmentation.3Plant specialization cannot therefore be considered in isolation from the degree ofspecialization of the mutualist partners. Evaluation of both sides of the mutualisticinteraction will yield insights into the mechanisms behind species? responses to habitatfragmentation.
