Rising temperatures caused by climate change could negatively alter plant ecosystems if temperatures exceed optimal
temperatures for carbon gain. Such changes may threaten temperature-sensitive species, causing local extinctions and
range migrations. This study examined the optimal temperature of net photosynthesis (Topt) of two boreal and four
temperate deciduous tree species grown in the field in northern Minnesota, United States under two contrasting temperature
regimes. We hypothesized that Topt would be higher in temperate than co-occurring boreal species, with
temperate species exhibiting greater plasticity in Topt, resulting in better acclimation to elevated temperatures. The
chamberless experiment, located at two sites in …
