Variation in quality of mountain birch and tea-leaved willow for mammal and insect herbivores: Differences among trees, among sites and between tree species
We evaluated palatability of winter dormant tree twigs to the mountain hare Lepus timidus and the grey-sided vole Clethrionomys rufocanus with captive animals. We tested differences among trees within sites, among sites, and between two tree species (the mountain birch Betula pubescens ssp. czerepan...
