摘要: The moose choice of birch clones was studied by offering nine European white plantlets to free‐ranging in a field cafeteria experiment. Twig quality, especially the defensive chemical content, affected feeding preference. Moose took bite larger diameter but tended consume less from with high phenol content. preferred small current annual shoots and few resin droplets.
