Discussion
The catastrophic decline of pollinators and other insects calls for a
thorough understanding of the underlying mechanisms to provide measures
for nature conservation and mitigate losses of ecosystem services. In
this study, we showed that two important pollinator guilds of Central
Europe responded differently to parameters of land-use intensification
and at different spatial scales. Further, our study indicates that
functional diversity of flower traits as a measure for habitat quality
seems to have no particular positive effect on pollinators, highlighting
the role of landscape processes to maintain pollinator diversity.
