calder summer undergraduate research symposium presentation

Project BaselineA Seed Bank to study plant evolution

Project Baseline:A seed bank to study how plants are evolving in response to global climate change- Multi-university, NSF-funded project- 2nd summer of 50-year project

How it BeganAfter a drought, garlic mustard seeds exhibited a change in flowering time

Why is the Baseline seed bank useful?

- Little currently known about the rate of evolution in the wild- Climate change alters selective pressures, affects evolution- Rich source of information about evolutionary questions for future generations

Why is the Baseline seed bank useful? (cont’d)

- Living genome bank allows for use of resurrection approach- allows us to distinguish between genotypic & phenotypic changes

Baseline Species & Sites- Both native and invasive- Common throughout the United States- thrive in frequently disturbed meadows - Collect at sites where we can return for several decades (university research forests, LTERs)

Rumex crispus, or curly dock

Impatiens capensis, jewelweed or touch-me-not

Rudbeckia hirta or black-eyed susan

Baseline Field Work

- Depends on phenology: the timing of the populations’ life cycle

- Cold, long winter resulted in later phenology than usual

Impatiens pallida

Where do you come in?- NYBG volunteers clean the seeds so they can

be packaged and sent to the storage facility.- The seeds will be stored until a scientist uses

them to conduct a resurrection-approach experiment!

Thank you for helping Project Baseline succeed!
