Evaluating the definition and distribution of spring ephemeral wildflowers in eastern North America

The paper defines and maps the distribution of spring ephemeral wildflowers in eastern North America using georeferenced data and remote sensing, finding that ephemeral behavior varies continuously across species ranges.

Phenological mismatch between trees and wildflowers: Reconciling divergent findings in two recent analyses

This paper investigates discrepancies between two studies on phenological mismatch using different datasets and finds that data extent and model design differences, rather than species or phenophase selection, explain the contradictory results.

Wildflower phenological escape differs by continent and spring temperature

The paper shows that wildflower phenological sensitivity to spring temperature is conserved across continents, but canopy trees in North America are more temperature-sensitive than in Asia and Europe.
