TL;DR: There is no evidence, however, that resource availability and global physicochemical parameters were different enough in the Mesozoic to have led to sauropod gigantism.

TL;DR: It is suggested that the decreasing ability for colonic water absorption in large grazing ruminants and the largest extant foregut fermenter, the hippopotamus, are an indication of this limit, and are the outcome of the competition of organs for the available space within the abdominal cavity.

TL;DR: Comparative physiology applies methods established in domestic animal science to a wider variety of species to lead to improved insight into evolutionary adaptations of domestic animals, by putting domestic species into a broader context.

TL;DR: Traditional explanations for herbivore niche differentiation along a BM gradient should not be based on allometries of digestive physiology, and differences in the scaling of wet gut contents and dry matter gut contents confirm a previous finding that the dry matter concentration of gut contents decreases with body mass.

TL;DR: It is proposed that very large body size does not automatically imply a digestive advantage, because long MRTs do not seem to be a characteristic of very large species only, and a potential body size limitation for herbivory on the lower end of the body size range is supported.
