A Joshua tree (Yucca brevifolia) dusted with snow following a spring snowstorm in Tikaboo Valley, Nevada. Joshua trees are part of a highly specialized pollination relationship with yucca moths. In Tikaboo Valley, two species of yucca moth co-occur, and trees pollinated by each moth species are morphologically distinct.

Willamette University students Tyler Starr (left) and Jeffrey Collins (right) collect morphological data from a Joshua tree (Yucca brevifolia) in Tikaboo Valley, Nevada. The morphological data, along with genetic information, will help the young scientists determine whether 'hybrid' trees grow in a population where two different pollinators coexist.
