“…Interspecific competition, predicted because of similarities in life styles, should vary in intensity with temporal variation in Microtus density. In areas of geographic sympatry with Microtus pennsylvanicus, Synaptomys cooperi has been reported from sphagnum bogs, dense forests, sedge/grass marshes, recent clearcuts, sparsely grassed openings in both deciduous and coniferous forests, and upland fields (Howell 1927, Coventry 1937, Hamilton 1941, Hooper and Cady 1941, Poole 1943, Stewart 1943, Smyth 1946, Odum 1948, Richmond and Rosland 1949, Barbour 1951, Connor 1959, Getz 1961, West and Hutchison 1964, Linzey and Linzey 1968, Doutt et al 1973, Kirkland 1977. Microtus occurs in habitats with dense herbaceous ground cover, but avoids woodlands except at times of high population density (Eadie 1953, Mossman 1955, Getz 1967, 1970a Grant 1972, Birney et al 1976.…”

These results suggest that in the southern Appalachians, Synaptomys is excluded from preferred habitats by Microtus and, as a result, lives where cover is sparse and food is low in nutritional value. Although these species do compete, this competition is relaxed when Microtus populations decline. When given access to preferred habitats the food habits of Synaptomys change and resemble those of Microtus, suggesting that the ultimate limiting resource is food. The combination of wider habitat tolerances by Synaptomys and temporal variation in intensity of competition allows coexistence of these species on a regional basis. Ecological Society of America
