The allometry of food intake in grazing ruminants
(1) A simulation model of grazing mechanics in ruminants shows that, due to the allometric relations of bite size and metabolic requirements to body size, small animals are able to subsist on shorter
ON THE RELEVANCE OF NONEQUILIBRIUM CONCEPTS TO ARID AND SEMIARID GRAZING SYSTEMS
The dynamics of arid and semiarid grazing systems are prone to the effects of highly variable rainfall, with droughts causing frequent episodic mortality in herbivore populations. This has led to the
Modelling the nutritional ecology of ungulate herbivores: evolution of body size and competitive interactions
TLDR
It is suggested that the upper limit to ungulate body size is determined by the ability to extract nutrients from feeding niches during the nadir of the seasonal cycle of resource quality and abundance.
The functional significance of the browser-grazer dichotomy in African ruminants
TLDR
There is little difference in digestive strategy between African ruminants with different morphological adaptations of the gut, after controlling for the effects of body mass.

Resource heterogeneity and ungulate population dynamics
It has been suggested that climatic variation has the effect on the dynamics of arid and semi-arid grazing systems of reducing animal numbers below the level at which they have much impact on
Megaherbivores influence trophic guilds structure in African ungulate communities
TLDR
It is shown that the different trophic guilds within African ungulate communities react differently to environmental factors (rain and soil), and that megaherbivores, and particularly elephants, appear to compete with mesomixed feeders and mesobrowsers.
Metabolic constraints on voluntary intake in ruminants.
TLDR
The empirical evidence for metabolic feedback shows that the animal's productive potential, which affects its ability to utilize nutrients, interacts with the balance of absorbed nutrients to regulate intake, and models that describe the phenomenon in terms of global variables can simulate the way constraints may operate without requiring or providing a deeper understanding of the metabolic processes involved.
DIET SELECTION IN GOATS: A TEST OF INTAKE-RATE MAXIMIZATION
TLDR
It is argued that the most likely explanation of the preference of goats among five grass species was accounted for by differences in intake rate or differences in species-specific attributes of the grasses is the difficulty of discriminating between alternatives of similar intake rate.
