. Plantations of Eucalyptus globulus Labill. have beenexpanding rapidly worldwide. The species is considered invasive in severalregions. While in the native range, post-dispersal seed predation is known toseverely limit eucalypt recruitment, there is no experimental evidence ofseed predation in the introduced range. We hypothesised thatE. globulus seeds largely escape predation in Portugal, which mayexplain its prolific recruitment in some locations. We tested this hypothesisin central Portugal by exposing E. globulus seeds to the localfauna. For comparison purposes, we also used seeds from locally commonspecies: Acacia dealbata Link (alien, larger, elaiosome-bearingseeds) and Cistus salviifolius L. (native, similarly sized seeds). Weinstalled 30 feeding stations across three study sites, each one dominatedby one study species. Each feeding station featured four feeders withdifferent animal-access treatments: invertebrates; vertebrates; full access;no access (control). We placed five seeds of each plant species every day ineach feeder and registered the number of seeds missing, eaten andelaiosome detached over 9 summer days. Eucalyptus globulus seeds were highly attractive to fauna in thethree sites. Nearly half of E. globulus seeds were predated orremoved, thus contradicting our hypothesis. Surprisingly,E. globulus and A. dealbata seeds were used by animals insimilar proportions and C. salviifolius seeds were the leastpreferred. Vertebrates were the predominant seed predators and preferred thealien seeds. Invertebrates used all seed species in similar proportions. Wefound spatial variation regarding the predominant type of seed predators andthe levels of seed predation according to the following patterns:predominance of vertebrates; predominance of invertebrates; negligible seedpredator activity. Locations with negligible seed predation were abundant andscattered across the study area. Such spatial variation may help to explainthe heterogeneous recruitment patterns of E. globulus seedlingsfound in previous studies.
