“…The fecal analysis method has been widely adopted to reveal the food habits of ungulates (Stewart, 1967;Todd and Hansen, 1973;Kessler et al, 1981). This method has an advantage to collect samples without sacrifice of animals, although it contains disadvantages to misrepresent the food habits because of different digestibilities of plants (Anthony and Smith, 1974).…”

“…We suspect the competitive relationship between the 2 2. Holechek et al 1982, Kessler et al 1981. Rumen analyses may have underestimated the proportion of spotted knapweed rosette leaves in diets because: 1) foliar material readily separated from leaf mid-veins and broke into small fragments, and 2) cervid mortality occurred disproportionately in forest habitats and during periods of deep snow cover.…”

Predicting seasonal diet in the yellow-bellied marmot: success and failure for the linear programming model

Seasonal diet selection in the yellow-bellied marmot (Marmota flaviventris) was studied at two sites in Montana during 1991 and 1992. A linear programming model of optimal diet selection successfully predicted the composition of observed diets (monocot versus dicot) in eight out of ten cases early in the active season (April-June). During this period, adult, yearling and juvenile marmots selected diets consistent with the predicted goal of energy maximisation. However, late in the active season (July-August), the model predicted the diet composition in only one out of six cases. In all six late-season determinations, the model underestimated the amount of monocot in the diet. Possible reasons why the model failed to reliably predict diet composition late in the active season are discussed.
