Overview of hypothesized and observed responses to higher moisture availability in traits related to water balance in Potentilla diversifolia plants on the Niwot Ridge alpine tundra LTER site (Colorado, USA)

Trait*	Hypothesized	Observed
Percentage wide vessels	↑	↑
Potential maximum conductivity	↑	↑
Percentage intervascular xylem	↓	↓
Specific leaf area (SLA)	↑	↑

* Traits developing after installation of a snow fence in 1993 that divided the population into a drier windward group and a moister lee-side group.
