Table 1.
List of functional traits and categories used to classify functional groups for birds and mammals in Mexico.
Fig 1.
Functional groups (FG) for species of birds and mammals occurring in Mexico.
Dendrogram and FG obtained for (A) 496 species of mammals and (B) 987 species of birds. Number in bars indicate the number of species in each FG. Color legends indicate the broader groups based on their feeding habits (invertivores, carnivores, herbivores, granivores, aquatic vertivores/invertivores, frugivores, nectarivores, scavengers [birds], omnivores, hematophagous [mammals]).
Fig 2.
FG of birds divided by seasonality depicting the contribution of resident, migrants, transient and accidental species, with an example of how one FG (invertivore, arboreal hunter) is distributed in Mexico and the number of species found along the country, adding the combined map for the winter season when all species coincide in Mexico.
Fig 3.
FG shared by species of mammals and birds, and the contribution of each taxonomic group, with an example of how one group (frugivore, semi-arboreal, arboreal gleaner) is distributed in Mexico when considering only mammalian species, only bird species, and both taxonomic groups combined.
Fig 4.
Functional group richness (number of functional groups) across Mexico, for (A) birds in the non-migratory season, (B) birds in the migratory season and (C) mammals. Blue polygon represents the Mexican Transition Zone, between the Nearctic region (north) and the Neotropical region (south) [61].
