VEGETATIVE REPRODUCTION BY LAYERING VERSUS SEXUAL REPRODUCTION IN A SPRUCE-FIR FOREST AT ALPINE TREELINE, MEDICINE BOW MOUNTAINS, USA
Alpine ecosystems offer a unique opportunity to study tree species at the edges of their distributions and physiological limits. Clonal growth has shown to be an advantageous trait for woody species in alpine zones because it provides protection from high winds, freezing temperatures, and ice …

Fine-Scale Mechanisms Influencing Germination Success, Seedling Growth and Survival in an Alpine Forest-Tundra Ecotone
Despite the expectation that treeline will advance as climate continues to warm, it has only done so in approximately half of all sites studied. One of the explanations for the nonresponse of treelines is based on reproductive limitations including seed production, germination, establishment and …

Population Structure and Biophysical Density Correlates of Whitebark Pine (Pinus albicaulis) at Two Treelines in the Northern Rocky Mountains
… a keystone species and an important component of treeline ecosystem dynamics; however, subalpine populations have declined nearly rangewide in recent decades. Though declines in subalpine forests have been well documented in the literature, few studies have assessed population structure and …
