Geologists with the University of Wyoming have performed a study that shows bedrock may be just as important as temperature and moisture in regulating the distribution of vegetation across mountain slopes. Assistant Professor Cliff Riebe was one of the researchers on the study and says they determined that plant growth is limited by the composition of the bedrock.

Riebe says the findings that bedrock geochemistry is as important as climate in regulating vegetation is important because it could be applied to granite rock formations throughout the world. Their study was recently published in the Proceedings of the National Academy of Sciences.
