On the other hand, all of the intense values of this 15N journal.pgen.1001210 variety correspond to isotope values of rodent species. Marsupials were concentrated inside a reasonably modest and higher position on the food chain (Fig two), probably relying on sources with fairly higher trophic levels (e.g. fungi, invertebrates, smaller vertebrates). Only one particular marsupial species, Gracilinanus microtarsus, presented reasonably reduce values of 15N (two.89), suggesting a diet program predominantly primarily based on C3 plant material (possibly fruits). Although we only captured one individual of G. microtarsus, our benefits contracts with other studies that consider this speciesPLOS 1 | DOI:ten.1371/journal.pone.0152494 April six,9 /Stable Isotopes and Diet program of Compact MammalsFig 3.

Interestingly, marsupials are also extremely concentrated within a smaller subset of 13C axis, indicating that theses species rely in comparable meals sources, likely derived from food chains primarily based on C3 plants. These benefits differ from the earlier classic dietary research, which regarded the didelphid marsupials as generalists and “omnivorous”, consuming a wide range of distinct fruits, invertebrates and compact vertebrates [60?2]. This `isotopic niche packing’ of marsupials in relation to rodents is actually a promising region of study and can bring new insights to know how these distinct lineages have shared sources along its history of coexistence in Neotropics. Rodents had been additional plastic in their use of meals sources with species distributed in up to three trophic levels.

Interestingly, there’s a clear distinction in carbon principal sources inside this second trophic level. Some species are really enriched in 13C (i.e. N. lasiurus and O. nigripes), whereas the other individuals are 13C depleted (e.g. A. montensis and T. nigrita). The latter pair of species share ecological traits concerning physique size, diet and vertical use of space [21], but differ in their period of activity: although T. nigrita has diurnal habits, A. montanensis has peaks of activity through the twilight.
