The relationship between diet and biomass was examined in the Amazonian ungulates (red brocket deer, grey brocket deer, collared peccary, white-lipped peccary, and lowland tapir) of Northeastern Peru. Tropical forest ungulates have lower biomasses than savanna or grassland ungulates, because in tropical forests the majority of primary production occurs in the canopy, well out of reach from terrestrial herbivores. Within the Amazonian ungulates, species that supplement their diet with animal material, namely the peccaries, obtain a greater crude and metabolic biomass, and higher reproductive rates than the purely herbivorous species. Omnivory appears to help terrestrial herbivores inhabiting closed canopy forests overcome some effects of food limitation.
在秘鲁东北部的亚马逊有蹄类动物（红短角鹿、灰短角鹿、领西貒、白唇西貒和低地貘）中，研究了饮食与生物量之间的关系。热带森林有蹄类动物的生物量低于热带稀树草原或草原上的有蹄类动物，因为在热带森林中，大部分初级生产发生在树冠层，陆生食草动物难以企及。在亚马逊有蹄类动物中，通过动物材料补充饮食的物种，即西貒，比纯食草物种获得更高的粗生物量和代谢生物量，以及更高的繁殖率。杂食性似乎有助于栖息在封闭树冠森林中的陆生食草动物克服食物限制的一些影响。
