The region of the Amazon rainforest where Josh Kielsmeier-Cook, a U of M plant pathology Ph.D. student, does field research is one of the most biodiverse locations on Earth. One hectare, or almost 2.5 acres, in Yasuní contains more species of trees than are found in all of North America. Unfortunately, oil drilling threatens parts of this biosphere reserve. For Kielsmeier-Cook, that means time is running out to classify and better understand the ecology of a particular fungal genus that may be useful in pharmaceuticals and bioenergy production.
