Introduction
Methods
Empirical networks
Empirical networks were constructed from the interactions recorded by Kopelke et al. (2017). This dataset consists of replicate samples of Salix (willow species) – willow-galling sawfly – predator interactions across Europe. Data collection spanned 29 years across 641 sites (some with repeat visits) revealing 1 173 links across sites and trophic levels. Sites spanned a large latitudinal (in the context of continental Europe) from Italy (39.00/deg N) to Norway (70.78/deg N). Making this a good dataset to interrogate regarding the aim of this paper owing to the large environmental gradient.
