Maybe you've tasted chestnuts roasting over an open fire, but have you ever heard of the tragedy of the American chestnut? This species, Castanea dentata, is effectively extinct -- thanks to the forces of the ruthless fungus Cryphonectria parasitica, agent in the now infamous chestnut blight. Shara Azad from Erika Edwards' Plant Diversity course at Brown University (Biol0430) investigates what happened to those thousands of acres of American chestnut forests and what glimmers of hope there may be in the future.
