Abstract |
Global change, especially landscape simplification, is
a main driver of species loss that can alter ecological interaction
networks, with potentially severe consequences to ecosystem functions.
Therefore, understanding how landscape simplification affects the rate
of loss of plant–pollinator interaction diversity (i.e., number of
unique interactions) compared to species diversity alone, and the role
of persisting abundant pollinators, is key to assess the consequences of
landscape simplification on network stability and pollination services. France, Germany, and Switzerland. We analysed 24 landscape-scale plant–pollinator
networks from standardised transect walks along landscape simplification
gradients in three countries. We compared the rates of species and
interaction diversity loss along the landscape simplification gradient
and then stepwise excluded the top 1%–20% most abundant pollinators from
the data set to evaluate their effect on interaction diversity, network
robustness to secondary loss of species, and flower visitation
frequencies in simplified landscapes. Interaction diversity was not more vulnerable than
species diversity to landscape simplification, with pollinator and
interaction diversity showing similar rates of erosion with landscape
simplification. We found that 20% of both species and interactions are
lost with an increase of arable crop cover from 30% to 80% in a
landscape. The decrease in interaction diversity was partially buffered
by persistent abundant generalist pollinators in simplified landscapes,
which were nested subsets of pollinator communities in complex
landscapes, while plants showed a high turnover in interactions across
landscapes. The top 5% most abundant pollinator species also contributed
to network robustness against secondary species loss but could not
prevent flowers from a loss of visits in simplified landscapes. Although persistent abundant pollinators buffered the
decrease in interaction diversity in simplified landscapes and
stabilised network robustness, flower visitation frequency was reduced,
emphasising potentially severe consequences of further ongoing land-use
change for pollination services. |
