Adaptive divergence is widely accepted as a contributor to speciation and the maintenance
of species integrity. However, the mechanisms leading to reproductive isolation, the genes …

Oak barrels serve two purposes in the production of distilled spirits: storage containers and
reaction vessels. It is the latter function which bestows barrel aged spirits with their unique …

Intraspecific trait variation has been singled out as an important mechanism by which
individuals can cope with environmental variations and avoid local extinctions. Here we …

We tested the effects of hybridization and introgression on the levels of leaf fluctuating
asymmetry (FA) in a hybrid zone between Quercus magnoliifolia and Quercus resinosa at …

Aim Information on the association between geographical patterns of hybridization and the
climatic niche requirements and co‐occurrence of the species involved can provide …

Trait-based approaches have emerged as promising strategies for understanding plant
adaptation mechanisms to the changing environment. At present, there are a large number …

Seed mass represents the reserves available for growth in the first stages of plant
establishment. Variation in seed mass is an important trait which may have consequences …

Quercus rugosa Nee (section Quercus) has a distribution from the southern United States to
Honduras. This study characterized leaf variation across the whole distribution of the …

Key message Leaf symmetry and leaf size are explained by genetic variation between and
within lineages and to a lesser extent by climatic factors, while leaf asymmetry can only be …

Background: Variation in leaf morphology is an important indicator of how plants respond to
different environmental conditions. Leaf trait variation is associated with physiological …
