Retention Ponds Can Significantly Decrease Runoff, Study Shows
University of Arkansas, Fayetteville

University of Arkansas researchers have simulated the effect of a series of retention ponds in the West Fork of the White River Watershed and found that construction of 22 one-acre ponds, with an average flood-pool depth of 8.2 feet, in sub-basin areas can decrease peak-flow runoff by about 15 percent. Such a retention pond system would have the potential to significantly decrease water loss from runoff in watersheds of at least 75,000 acres.

CEO Retirements Cause Negative Reactions From Shareholders, Markets
University of Arkansas, Fayetteville

CEO retirements – the most common reason for executive succession and yet a relatively overlooked area of research – are assumed to be an inconsequential part of normal business and therefore not disruptive to an organization. A new study by management researchers at the University of Arkansas shows this conventional assumption to be inaccurate. According to market data, shareholders perceive CEO retirements to be a significant disruption to the viability of an organization.

New Study Ties Tooth Wear in Fossils to Diet, Validating Decades of Research
University of Arkansas, Fayetteville

A team of researchers has validated data and found a new model for paleontologists to use to track the diet of our ancient ancestors and animals by analyzing the wear on their teeth. Dental wear is among the top techniques scientists use to reconstruct and analyze dietary patterns of human ancestors and animals. Researchers recently questioned the validity of tooth-wear analysis, however, stating that environmental elements such as grit on food was likely responsible for wear. This challenge has led paleontologists to question decades of results. This study validates the use of tooth wear for understanding diet of fossil animals.
