The different strategies of Pinus sylvestris and Larix sibirica to deal with summer drought in a northern Mongolian forest–steppe ecotone suggest a future superiority of pine in a warming climate
Pinus sylvesteris L. is locally common at the lower forest line to the steppe in Mongolia’s taiga forests, which are otherwise dominated by Larix sibirica Ledeb. The factors responsible for the occurrence of pine patches in the forest–steppe ecotone are insufficiently studied. We analyzed the respon...
