Fig 2. Isotope plot depicting means isotope values (δ¹⁵N and δ¹³C) of rodent (gray dots) and marsupial (blue dots) species from Atlantic rainforests, with respective standard isotope ellipses, for each studied site and all sites polled together.

Isotope values were corrected downward 2.7‰ (for δ¹⁵N) and 2.4‰ (for δ¹³C) to account for trophic enrichment. Isotope values of the potential food resources are represented in boxplots. Species code: 1 = Didelphis aurita; 2 = Gracilinanus microtarsus; 3 = Juliomys pictipes; 4 = Marmosops incanus; 5 = Metachirus nudicaudatus; 6 = Monodelphis Americana; 7 = Monodelphis iheringi; 8 = Monodelphis scalops; 9 = Monodelphis sp.; 10 = Philander frenatus; 11 = Akodon cursor; 12 = Akodon montensis; 13 = Blarinomys breviceps; 14 = Brucepattersonius soricinus; 15 = Delomys dorsalis; 16 = Delomys sublineatus; 17 = Euryoryzomys russatus; 18 = Necromys lasiurus; 19 = Oligoryzomys nigripes; 20 = Sooretamys angouya; 21 = Thaptomys nigrita; 22 = Trinomys iheringi.
