Water-use responses of 'living fossil' conifers to CO2 enrichment in a simulated Cretaceous polar environment.

abstract：BACKGROUND AND AIMS:Spring ephemerals have a specific life-history trait, i.e. shoot growth and sexual reproduction occur simultaneously during a short period from snowmelt to canopy closure in deciduous forests. The aim of this study is to clarify how spring ephemerals invest resources for seed production within a res...
