Geographic variation in trees has been investigated since the mid‐18th century. Similar
patterns of clinal variation have been observed along latitudinal and elevational gradients in …

In the face of anthropogenic climate change, species must acclimate, adapt, move, or die.
Although some species are moving already, their ability to keep up with the faster changes …

Although plants have moved across the landscape in response to changing climate for
millennia, projections of contemporary climate change suggest that forest tree species and …

There is growing concern that flooding is becoming more frequent and severe in Europe. A
better understanding of flood regime changes and their drivers is therefore needed. The …

The benefits and risks of human-aided translocation of individuals within the species range,
assisted gene flow (AGF), depend on the genetic divergence, on the rate and direction of …

The increased availability of spatial data and methodological developments in species
distribution modelling has lead to concurrent advances in phylogeography, broadening the …

Populus tremuloides (trembling aspen) recently experienced extensive crown thinning,
branch dieback, and mortality across North America. To investigate the role of climate, we …

Warming has been particularly strong at high latitudes in recent decades and bioclimatic
models predict northern shifts in optimal conditions for most species. Climate is a strong …

Aim Determine if differences in the climatic niche between conspecific adult and juvenile
trees of the western U nites S tates vary by species traits and to assess if forest canopies …

Species environmental niches are central to ecology, evolution, and global change
research, but their characterization and interpretation depend on the spatial scale …
