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.
