Table 2. Richness, comparison between the areas of the isotopic niche space (SEAC) occupied by rodents vs. marsupials, and percentage of the niche overlapped with the other group for marsupials and rodents in three sites of the Atlantic forest.
| Site | Richness | SEAC (‰2) | % Marsupials' niche overlapped with rodents' niche | % Rodents' niche overlapped with marsupials' niche | ||
|---|---|---|---|---|---|---|
| Rodents | Marsupials | p-value | ||||
| Botelho | 18 | 17.28 | 1.59 | <0.001 | 12.87 | 1.21 |
| Itamambuca | 10 | 20.11 | 0.49 | <0.001 | 31.43 | 1.5 |
| Vargem Grande | 9 | 28.3 | 2.34 | <0.001 | 94.75 | 13.15 |
| All sites | 22 | 18.86 | 1.97 | <0.001 | 46.77 | 4.95 |
The isotopic data were defined in delta notation (δ) and reported in parts per mil (‰) of international standards.
