Inasmuch as the earth supports a wide variety of terrestrial communities differing in size and species composition, and because no two of these communities are identical in terms of foods and feeders, a correspondingly great complexity of feeding relationships is to be expected. Consequently, food-habit studies must take cognizance of dynamic interplay among many factors which vary with place and time, including that between food availability and the food preferences of consumers. Although ecologists have developed some sophisticated models of the various feeding interactions (e.g., Holling, 1963, 1964, 1966), the number of species whose food-habits and preferences have been carefully studied is small. Further knowledge is needed, particularly of the feeding biology of organisms in specific, limited communities and ecosystems.
