The treeline is an obvious ecotone between forest and tundra ecosystems. Climatic warming is expected to lead to the treeline advancing, although in many cases this has not been observed. This is most likely because other factors can also influence treeline dynamics, notably land use and herbivory in European treelines. In this study, the roles of climate and herbivory as determinants for change in stem number, growth and mortality responses of treeline ecotone trees were investigated.

气候和草食在沿纬度梯度驱动林木动态中的相对作用

树线是森林和苔原生态系统之间的明显过渡带。气候变暖有望导致林木行进，尽管在许多情况下还没有观察到。这很可能是因为其他因素也会影响林木动态，特别是欧洲林木中的土地利用和草食。在这项研究中，研究了气候和草食作为决定树上交错带树木茎数，生长和死亡率响应变化的决定因素。
