Scientists crack rhino horn riddle

eeded in this area," said Tobin Hieronymus, a doctoral student in biological sciences and lead author on the study.

The study also found that the melanin and calcium patches appear in yearly growth surges but the effects of temperature, diet and stress on the growth are still unknown. The results of the horn growth study may be of interest to conservation groups whose goal is to strengthen rhino populations and reduce the poaching of horn for the black market.

"Ultimately, we think our findings will help dispel some of the folk wisdom attached to the horn. The more we can learn about the horn, the better we can understand and manage rhino populations in the wild and in captivity," said Lawrence Witmer, a professor of anatomy in Ohio University's College of Osteopathic Medicine and director of the project.
