My guest today is Shelley Sianta, a PhD student at UC Santa Cruz, and she studies evolution in a group of plants that have specialized on serpentine soils. These may sound like sketchy conditions and indeed they are. Serpentine soils are high in toxic metals and low in precious nutrients. As such, the plants that live there have evolved a variety of coping mechanisms. Its these coping mechanisms that interest Shelley Sianta as they may be at the root of why we see such high rates of endemism on these toxic soils. Listen in for a fascinating exploration of plant evolution.
