Marsupials had been concentrated in a comparatively small and higher position around the food chain (Fig two), likely relying on sources with relatively high trophic levels (e.g. fungi, invertebrates, small vertebrates). Only 1 marsupial species, Gracilinanus microtarsus, presented relatively reduce values of 15N (two.89), suggesting a diet program predominantly primarily based on C3 plant material (likely fruits). Even though we only captured 1 individual of G. microtarsus, our final results contracts with other studies that take into consideration this speciesPLOS A single | DOI:ten.1371/journal.pone.0152494 April 6,9 /Stable Isotopes and Diet plan of Smaller MammalsFig three.

Interestingly, marsupials are also hugely concentrated in a little subset of 13C axis, indicating that theses species rely in equivalent food sources, likely derived from food chains based on C3 plants. These results differ from the earlier classic dietary studies, which viewed as the didelphid marsupials as generalists and "omnivorous", consuming a wide variety of various fruits, invertebrates and small vertebrates [60?2]. This `isotopic niche packing' of marsupials in relation to rodents is actually a promising area of study and can bring new insights to understand how these diverse lineages have shared resources along its history of coexistence in Neotropics. Rodents were extra plastic in their use of meals sources with species distributed in as much as 3 trophic levels.

Interestingly, there is a clear distinction in carbon primary sources within this second trophic level. Some species are exceptionally enriched in 13C (i.e. N. lasiurus and O. nigripes), whereas the other people are 13C depleted (e.g. A. montensis and T. nigrita). The latter pair of species share ecological characteristics concerning body size, diet program and vertical use of space , but differ in their period of activity: although T. nigrita has diurnal habits, A.
