Historical and ongoing hybridization between the oak species Quercus petraea and Q. robur leads to difficulty in identifying the taxonomic status of individual trees. Despite this, Beatty et al. using genetic and...

Positive pCO2–stomatal frequency relationship in Quercus
Hu et al. determine a new positive relationship between atmospheric pCO2 and stomatal frequency in Quercus guyavifolia.
Stress tolerance of recalcitrant embryonic axes of Quercus
A study finds that four Quercus species adapted to arid and semi-humid climates still produce recalcitrant seeds.
Cambial reactivation and formation of earlywood vessels in oak
The continuous formation of earlywood vessels is crucial for the growth of ring-porous hardwoods. Kudo et al. study Quercus serrate seedlings and find that a combination of localized heating and disbudding of dormant...
Individual mating patterns in mixed oak stands
Trees can mate assortatively, which may be a result of variable compatibility among trees due to genetic and/or environmental factors.
Turnover of foliar N absorbed at different times
Although nitrogen turnover within plants has been studied intensively, the fate of N absorbed at different times and particularly over winter is not completely understood. Ueda et al. trace N absorbed at different times...
