| dc.description.abstract | To investigate whether endangered endemic plants of the Azores are threatened by pollinator limitation, we studied the insect pollinator communities of Azorina vidalii, Euphrasia azorica, Myosotis azorica and Solidago azorica on Corvo Island. We found no evidence for dependence on a specialised pollinator. Instead, we found five to 21 mostly generalist insect pollinators per plant species, six of them probably introduced species. Diptera, with at least 12 species, and Hymenoptera, with at least nine species, are the most important insect orders and also most important in visitation frequency. The relatively high pollinator diversity for each of the studied plants and the high proportion of generalists indicate that the pollination networks of the four study plant species are rather resilient, i.e. the loss of a species would not constitute an immediate threat. Seed counts and numbers of juvenile plants indicate that reproductive success of all four species is stable. Altogether, our results suggest that there is no pollinator limitation in the four study species. Conservation measures should therefore focus on other threats, on Corvo mainly on grazing pressure. | en |
