These California wildflowers could save other plants
The mountain jewelflower, a widespread California wildflower, is increasingly vulnerable due to shifting rainfall patterns caused by climate change. Researchers at UC Davis have studied the species' seed dormancy and germination strategies to understand how it and related jewelflowers may cope with unpredictable climates. Their findings aim to inform broader conservation efforts for other native plants facing similar environmental pressures.
- ▪The mountain jewelflower (Streptanthus tortuosus) occupies diverse habitats across California but is threatened by later onset of the wet season and erratic precipitation.
- ▪Scientists have shown that desert annuals use seed banks with varied dormancy periods to hedge against drought, a strategy they are investigating in jewelflowers.
- ▪By analyzing seed germination and subsequent seed production in jewelflowers, researchers hope to develop insights that can be applied to protect many other native plant species.
- ▪The study builds on a decade of collaborative work among plant biologists and ecologists to model climate‑adaptation mechanisms across multiple species.
