Site selection
Field sites were located on the Atherton Tablelands (17º 18’ S, 145º
29’E to 17º 36’S, 145º 44’ E) in northeast Australia (Fig. S1).
Twenty-four sites were selected in four different land-use types (six
replicates per land-use) within a mosaic agricultural landscape: remnant
forest, avocado orchard, dairy farming, and arable rotation cropping
(Fig. S1). These represent the major agricultural and natural land-uses
in the study area. Sites were separated by at least 1.5 km, with most at
a distance of 3 km from the nearest neighbouring site. These distances
are greater than average foraging flight and pollen transport distances
for our focal insect taxa, which are generally less than 1.5 km
(Zurbuchen et al. 2010; Rader et al. 2011; Smith &
Mayfield 2015).
