Feeding strategy of two rodent species in a set-aside field and its influence on alimentary tract morphometry
Abstract We examined the feeding strategy of two dominant rodents, the common vole ( Microtus arvalis ) and the pygmy field mouse ( Apodemus uralensis ), in set-aside fields over a period of 1 year. Diet analysis revealed dominance of green plant shoots in common vole’s diet and seeds in the diet of...
