Resumen:
Agricultural land management modify environments in such a way that ecosystem functions areimpaired. The establishment of exotic plants, favoured by agricultural landmanagement, may alter the foraging behaviour of native floral visitors andconsequently the pollination service they provide. To determine whetheragricultural land management affects the pollination service provided by floralvisitors for the most abundant plant species in a Pampean grassland ecosystem,we compared the pollination service of native and exotic entomophilous plantsin landscape fragments with or without current agricultural usage. Both thequantity (number of conspecific pollen grains deposited on stigmas) and quality(proportion of heterospecific pollen grains deposited on stigmas) of thepollination service was estimated for four to nine entomophilous plants in eachlandscape fragment. Agricultural land management reduced the quality of thepollination service due to an increase in the deposition of heterospecificpollen on stigmas.
