“…the rate of species extinctions that would occur if the humans were not around) and consequently we are living in a planet with a biodiversity crisis ( [42] Pim 2014). In particular, the local or functional extinction of animal populations by those human activities a process called defaunation (Galetti & Dirzo, 2012), is associated with a decrease in ecosystems integrity (Bello, et al, 2015; Gutierrez-Arellano & Mulligan [5]; Munguía [6]. Wild fauna, through trophic interactions participate in key ecological processes like predation, seed dispersal, litter respiration and decomposition, carrion removal, herbivory, maintenance of water quality and stream restoration, trampling of seedlings, dung removal, pollination and plant recruitment, carbon cycling, soil erosion and keeping cattle fodder Dirzo [7] and therefore wild fauna have a critical role in the long term prevalence on the ecosystems functioning.…”

“…Mammals play a vital role in the ecosystem and have diverse functional ecological roles (Lacher Jr. et al 2019), which makes them an excellent group to evaluate the human influence on functional diversity. Previous studies have shown that the least impacted sites have a higher representation of certain functional groups such as carnivores, frugivore-herbivores, and arboreal mammals (Munguía-Carrara et al 2019). On the other hand, highly fragmented sites have lower functional diversity compared to partially fragmented and continuous forests (Ahumada et al 2011).…”

Functional diversity quantifies the distribution and range of functional traits of species that influence ecosystem processes. We evaluated the functional diversity of the medium and large-sized mammals in a tropical rainforest in Southern Mexico to determine which landscape characteristics associated with human activities affected the composition of mammal functional diversity and functional group abundances. We used camera-traps to document the diversity and composition of medium and large-sized mammals at four sites with different levels of protection and management. We estimated species richness, diversity, and functional diversity for each site, and compared these indices between sites to understand the effects of biodiversity loss in ecosystem dynamics and to detect ecological patterns driven by human perturbation. The density of human settlements was the main covariate related to low species richness and low abundance of large mammals with specialized diets and low population densities. Poaching and other human activities in forested areas near human settlements might have caused large herbivore and specialized carnivore populations to decrease, and populations of medium-sized rodent species to increase. Our results indicated that human perturbation in forested areas had also an impact at the functional level reducing the abundance of some functional groups, and this might have negative consequences for tropical rainforest functions in the long term. Effective management actions should be implemented in Protected Areas with a high density of human settlements nearby to prevent the decline of mammals’ functional groups and negative consequences for tropical rain forests’ ecological functions.

“…The combination of these traits resulted in a classification of 22 trophic guilds for birds and 27 for mammals, and each taxonomic group was assembled into eight broader groups based on their feeding habits [ 30 ]. This classification of functional traits has been used to study a wide range of topics as the composition of species, trophic guilds and trophic relationships in communities [ 31 ]; activity patterns and temporal variation of species and trophic groups [ 32 ]; ecological integrity of ecosystems [ 33 ]; impact of urbanization and fragmentation [ 34 ]; transmission of diseases or the presence of parasites related to ecological traits [ 35 ], and proposing restoration and conservation actions [ 36 ].…”

There has been a recent exponential growth in the study of functional trait ecology. Nonetheless, the study of functional traits and functional groups has been limited for terrestrial vertebrates. We conducted a classification update of functional groups (FG) of birds and mammals in Mexico, and determined the distribution patterns of FG species richness in different ecosystems nationwide. We selected six functional traits (feeding habit, locomotion, feeding substrate and technique, activity period, seasonality, and body size) obtained for 987 and 496 species of birds and mammals, respectively. A cophenetic correlation analyses resulted in values of 0.82 for the bird species dendrogram, and 0.79 for the mammal species dendrogram showing that the structures adequately reflected the similarity between observations. We obtained 52 FG for birds, assembled into 9 broader groups based on their feeding habits (16 invertivores, 6 carnivores: 5 herbivores, 9 aquatic vertivore/invertivore, 5 granivores, 1 scavenger, 3 nectarivores, 4 frugivores, and 3 omnivores). We obtained 35 FG for mammals, assembled into 9 broader groups based on their feeding habits (4 granivores, 10 herbivores, 1 nectarivore, 4 frugivores, 8 invertivores, 3 omnivores, 2 aquatic vertivore/invertivore, 1 hematophagous, and 2 carnivores). Overall, the distribution of FG species richness for birds and mammals gradually increased from the Nearctic to the Neotropical region, following a typical latitudinal species richness pattern. Few FG of migratory birds, and FG of granivore and herbivore mammals showed more species in the Nearctic and in the transitional regions. Our study provides a baseline for identifying ecological functions of species of birds and mammals in different ecosystems in Mexico, and contributes to understand the relationship between species diversity, community structure and ecosystem functioning. Identifying spatial patterns of functional trait diversity is important as biodiversity loss has a negative impact on ecosystem functioning and provision of environmental services.
