Sampling Design-- Illustration of how environment (“habitat patch”), host bat, and parasitic bat fly each influence the microbiomes within bat flies (A; see in-text description of line colors). Sampling map constructed in QGIS v3.12 of REGUA area sites with fragments outside of REGUA labelled with the prefix “F” and ordered from smallest (F1) to largest (F10; B), the extent of the sampled area is shaded in black in the map at the top right, and the southern sites are mapped in relation to REGUA in the map on the bottom right. Green area of the map on the left indicates forested habitat based on imagery from SOS Mata Atlántica, while white areas are all non-forested habitat types.
