Última The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach Ecología austral Paiaro,Valeria; Cocucci,Andrea A; Oliva,Gabriel E; Sérsic,Alicia N. The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe. The identity of its floral visitor assemblage and to what extent this species depends on bird pollination for sexual reproduction is yet unknown. A. desideratum's vast distribution includes climatic gradients, which may promote geographical shifts in its floral visitors. The aims of this study were to determine the species dependence on pollinators to set fruits, to identify its floral visitor assemblages, to document possible geographical and environmental variation of these assemblages across the species range and to assess their temporal constancy. We conducted different pollination treatments in several...
