Frost ring distribution in Araucaria araucana trees from the xeric forests of Patagonia, Argentina

Frost rings are defined as anatomically abnormal and ecophysiologically pathological structures. We studied frost injuries in tree-rings of Araucaria araucana trees growing at the northern limit of its natural distribution. We recorded 121 frost injuries at two sites in the northern xeric distributi...
