Evolutionary Constraints: Phenology and elevational range limits in an annual plant
All species have limits to their geographic distributions and many range limits are stable over centuries, indicating a failure to adapt to conditions beyond the range edge. This simple observation contradicts copious ...
Stochastic and adaptive processes affect rapid evolution of two invasive plants in North America
Evolution can occur rapidly on timescales of years to decades. In addition to adaptive responses to natural selection, stochastic processes such as gene flow and genetic drift may influence rapid evolution in many species. ...
