Surface enlargement in the rumen of free-ranging muskoxen (Ovibos moschatus) - Zurich Open Repository and Archive


Clauss, Marcus; Adamczewski, J; Hofmann, R R (2010). Surface enlargement in the rumen of free-ranging muskoxen (Ovibos moschatus). European Journal of Wildlife Research, 56(2):181-185.

Abstract

The intraruminal papillation pattern indicates the degree of rumen contents stratification, and is related to the feeding niche of a ruminant. Muskoxen (Ovibos moschatus) display a variety of morphophysiological adaptations typical for grazers. We investigated the intraruminal papillation of 22 free-ranging muskoxen from 5 different months, by comparing the surface enlargement factor both between seasons, and between individual rumen regions. The seasonal pattern of rumen papillation indicated a distinct seasonality in food quality. The intraruminal papillation indicated a moderate degree of rumen contents stratification typical for intermedate feeders. The nutritional ecology of muskoxen is characterized by specific morphophysiological adaptations to a grass-dominated diet that nevertheless allow extensive seasonal use of browse forage.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
