Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

Understanding processes that limit species' ranges has been a core issue in ecology and
evolutionary biology for many decades, and has become increasingly important given the …

A key issue in predicting how ecosystems will respond to environmental change is
understanding why populations and communities are able to live and reproduce in some …

Anthropogenic climate change is projected to become a major driver of biodiversity loss,
destabilizing the ecosystems on which human society depends. As the planet rapidly warms …

Plastic traits are argued to favor the establishment of invasive alien plants and to evolve
during the invasion process, so that invasions may be favored by both plasticity and …

Background Altitudinal variation in vascular plant richness and endemism is crucial for the
conservation of biodiversity. Territories featured by a high species richness may have a low …

Rapid environmental change is forcing populations into environments where plasticity will
no longer maintain fitness. When populations are exposed to novel environments …

Environmental stress at high altitudes drives the development of distinct adaptive
mechanisms in plants. However, studies exploring the genetic adaptive mechanisms of high …

Anthropogenic change exposes populations to environments that have been rare or entirely
absent from their evolutionary past. Such novel environments are hypothesized to release …

Three Mediterranean oak species were considered in this study: one evergreen oak
(Quercus suber, the most tolerant to drought) and two winter-deciduous oaks (Q. faginea …
