title: Moose and birch: How to live on low-quality diets.
abstract: Ten years ago, the question of forage use by moose largely focused on whether nutritive factors or secondary compounds determined their use of individual tree species. Today, it is clear that both are important. Research during the last few years has tried to explain the hierarchical decisions in the foraging patterns of moose.
