Two-Species Forests at the Treeline of Siberian Mountains: An Ecophysiological Perspective under Climate Change. | LitMetric

In an underexplored region of the East Sayan mountains, ecophysiological traits of two conifers, Du Tour and Ledeb., have been studied. The goal was to predict which of the species co-dominating the same habitat is more vulnerable under prospective climate change. Along a transect from the treeline to the floodplain, photosynthetic pigment content and electron-transport rate (ETR) were measured in needles of neighboring trees of the species. From 570 to 1240 m a.s.l., does not suffer from stress factors during the growing season, while does. The latter is reflected in a decrease of pigment content and ETR with the increase of altitude. A stronger climate-change trend (probably to more dry and warm conditions) will likely favor the shift of upper in altitudes, and only under the pine shelter might the fir survive the changes.
