title: Data from: Geographical variation in mutualistic networks: similarity, turnover and partner fidelity

description: Although species and their interactions in unison represent biodiversity
 and all the ecological and evolutionary processes associated with life,
 biotic interactions have, contrary to species, rarely been integrated into
 the concepts of spatial β-diversity. Here, we examine β-diversity of
 ecological networks by using pollination networks sampled across the
 Canary Islands. We show that adjacent and distant communities are more and
 less similar, respectively, in their composition of plants, pollinators
 and interactions than expected from random distributions. We further show
 that replacement of species is the major driver of interaction turnover
 and that this contribution increases with distance. Finally, we quantify
 that species-specific partner compositions (here called partner fidelity)
 deviate from random partner use, but vary as a result of ecological and
 geographical variables. In particular, breakdown of partner fidelity was
 facilitated by increasing geographical distance, changing abundances and
 changing linkage levels, but was not related to the geographical
 distribution of the species. This highlights the importance of space when
 comparing communities of interacting species and may stimulate a
 rethinking of the spatial interpretation of interaction networks.
 Moreover, geographical interaction dynamics and its causes are important
 in our efforts to anticipate effects of large-scale changes, such as
 anthropogenic disturbances.
