Diversity and activity patterns of medium- and large-sized terrestrial mammals at the Los Tuxtlas Biosphere Reserve, México

Studies on diversity of animal communities allow determination their species richness and composition. This information is particularly relevant to establish sound conservation programs in biosphere reserves, where human activities should be focused the sustainable use natural resources ensure biodiversity protection. study estimated determined composition activity patterns medium- large-sized terrestrial mammals Los Tuxtlas Biosphere Reserve (LTBR) located Veracruz, Mexico. We set 18 camera traps record medium from August 2016 January 2017. calculated trapping rate, guilds, species. Diversity was with Hill numbers. compared our estimates other studies tropical forest obtained 308 independent captures 13 species; Cuniculus paca Dasyprocta mexicana were highest rate. Order-0, order-1, order-2 values 13.99, 6.50, 4.75 effective species, respectively, which ranks LTBR fourth-most diverse reserve six rainforest sites southern recorded representing five trophic frugivore-folivores (five species) omnivores (three ranked highest. All primarily nocturnal (six or diurnal species). Tamandua mexicana, Leopardus pardalis, L. wiedii, Eira barbara are listed as endangered Mexican Official Standard Norm NOM-059-2019, wiedii near threatened IUCN Red List Threatened Species. able 40.6 % mammal known inhabit LTBR. The absence such large predators herbivores notable. Comparison Mexico show that landscape degradation impoverishing communities.
