For its evening program on February 20th, the Gila Native Plant Society has invited plant ecologist Justin Zweck to give a presentation on the pollination strategies of plants in the genus Dalea.

While some species feature the typical "papillionoid" form in which the anthers and stigma are enclosed within the petals, others have a more open form. By comparing pollination systems within and between forms, Justin tested hypotheses regarding the advantages and disadvantages of specialist vs. generalist pollination. You will leave this talk with a deeper understanding of the evolutionary ecology of Dalea species, legumes, and generalist-specialist pollination systems at large.

The program will be hybrid – in person and via Zoom – on Friday, February 20, 2026, at 7:00 pm. All are welcome. It will be live on the WNMU campus in Harlan Hall, Room 111. Those who prefer to attend online may request a Zoom link from gilanative@gmail.com.
