American ginseng (Panax quinquefolius L.) is an uncommon to rare understory plant of the
eastern deciduous forest. Harvesting to supply the Asian traditional medicine market made …

Reciprocal transplant experiments designed to quantify genetic and environmental effects
on phenotype are powerful tools for the study of local adaptation. For long‐lived species …

Management of domesticated ungulates on grasslands has the potential to affect ecosystem
function at landscape to global scales. In the southwestern United States, introduction of …

Local adaptation and species interactions have been shown to affect geographic ranges;
therefore, we need models of climate impact that include both factors. To identify possible …

Tools for exploring and communicating the impact of uncertainty on spatial prediction are
urgently needed, particularly when projecting species distributions to future conditions. We …

Non-wood forest products (NWFPs) derived from understory plants are attracting attention
about sustainable forestry development. Geographical distribution and climate correlates of …

Environmental stochasticity can have profound effects on the dynamics and viability of wild
populations, and habitat heterogeneity provides one mechanism by which populations may …

Over the next century, the conservation of biodiversity will depend not only on our ability to
understand the effect of climate change, but also on our capacity to predict how other factors …

The response of vegetation to climate change has implications for the carbon cycle and
global climate. It is frequently assumed that a species responds uniformly across its range to …

PREMISE OF THE STUDY: Theory predicts that limited gene flow between populations will
promote population differentiation, and experimental studies have found that differentiation …
