Forage Quality and Aggregation by Large Herbivores
Abstract
Three general hypotheses have been proposed to explain why many large herbivores have highly aggregated patterns of distribution: dilution of predation risk, maintenance of forage in an immature but highly nutritious growth stage, and ideal free distribution in relation to spatial variation in either forage quality or primary productivity, Evaluation of the latter two hypotheses has been hampered by lack of a formal theoretical framework for assessing the effects of forage quality on resource acquisition by herbivores. A model is proposed that demonstrates how trade-offs between instantaneous intake and forage digestibility might lead to optimal rates of energy intake at iow to intermediate levels of forage abundance. Simulations based on the energy-intake model suggest a number of key environmental factors that should determine the impact of forage maturation and spatial variation on herbivore distribution patterns. All of the proposed advantages of aggregation may have general applicability, but the relative importance of each probably varies according to the specific circumstances facing a given herbivore population

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
