Legacy of the Last Glacial on the present-day distribution of deciduous versus evergreen boreal forests
Issue Despite their rather similar climatic conditions, eastern Eurasia and northern North America are largely covered by different plant functional types (deciduous or evergreen boreal forest) composed of larch or pine, spruce and fir, respectively. I propose that these deciduous and evergreen bore...
