Reproductive consequences of flower damage in two contrasting habitats: The case of Viola portalesia (Violaceae) in Chile

The indirect impact of flower herbivory on plant reproduction depends on the pollination environment, particularly on the presence or absence of pollinator species with the ability to discriminate damaged from undamaged flowers. The change in pollinator assemblages, due to habitat modification, may...
