Field and greenhouse experiments
Are those ghosts? Nope, they're whole-plant pollinator exclusion bags! Chamaecrista fasciculata has indeterminate growth and produces flowers along all of its branches, so covering the entire plant was the only option for excluding pollinators. I purchased all of the bridal tulle and hula hoops I could find within 20 miles to construct these.
Is seed dormancy affected by climate change? I'm exploring that question now by excavating seeds buried in a snow-manipulation experiment. To differentiate between a dormant and non-viable seed that didn't germinate, I dissect them and submerge them in a stain that will turn respiring tissue pink. This is what dormant embryos look like after they have been stained!
