We examined seedling survival and net growth for three years in contrasting canopy type (closed canopy vs. gap) and neighbor density (clipped versus unclipped) environments for northern, central and southern populations of sugar maple (<i>Acer saccharum</i>) representing a climate-of-origin gradient, experimentally planted from Arkansas, USA to Ontario, Canada at ten forested sites along a 1,700 km transect spanning beyond the species’ range.

本研究针对沿气候起源梯度分布的糖枫（Acer saccharum）北部、中部与南部种群，于美国阿肯色州至加拿大安大略省范围内，在横跨1700公里且覆盖该物种自然分布范围以外区域的10个森林样地中开展实验种植；随后在不同冠层类型（密闭冠层与林隙）及邻体密度（修剪组与未修剪组）的环境条件下，对幼苗的存活率与净生长量进行了为期三年的监测。
