Methods

We obtained the medium- to large-bodied mammal records—also including small-mammals with a strong prior documented relationship with the trees (e.g. Cricetidae and small marsupials)—via camera trapping (Bushnell ®; trophic HD model). Inventories occurred from late 2013 to early 2017 and intentionally coincided with the araucaria seed availability, with the fruitification of feijoa. In each site, we installed from 9 to 10 camera traps at ca. 30 cm from the ground. The traps were intentionally placed on natural trails and paths used by mammals. We distributed the camera traps in different environments. In total, we sampled 102 points and the sampling duration at each point ranged from 30 to 61 days, totaling a sampling effort of 11,956 camera-trap-days.
