The microhistological technique: testing two central assumptions in south-central New Mexico [when determining dry-weight composition of masticated forage samples from steers grazing Bouteloua gracilis rangeland]

Two central assumptions of the microhistological technique were tested for their accuracy. The estimation of particle density by relative frequency proved to be accurate for equal-sized plant fragments. Ratios of identifiable to nonidentifiable fragments were neither equal to one nor equal between g...

Description
Summary:Two central assumptions of the microhistological technique were tested for their accuracy. The estimation of particle density by relative frequency proved to be accurate for equal-sized plant fragments. Ratios of identifiable to nonidentifiable fragments were neither equal to one nor equal between grass and forb fragments.
