1980, MacCracken and Hansen 1984). The consumption of different 
species at different times of year may be related to the water con- 
tent (Getz 1966, Dunson and Lazell 1982), availability of nutrients 
and secondary compounds (de la Cruz and Poe 1975), or the amount 
of fiber in different stages of plant growth cycles.
