What processes determine the direction and rate of range shift change in response to global change? How generalizable are plant responses to climate change? What is the most appropriate scale to study plant responses to climate change?
Despite more rapid warming during winter months than summer months, relatively little is known on the effects of winter warming. Warmer winters and declining snowpacks are affecting species. The question is whether or not the net effect of winter warming will be good.
Species traits conferring differences in sensitivity and ability to respond to global changes may influence species ability and need to track shifts in habitable climate space. Traits provide clues into species near-term and long-term response to climate change.
