Using feces to identify species

According to a press release from Northern Arizona University, Drs. Faith Walker and Carol Chambers at the Bat Ecology & Genetics Lab have developed a system called Species From Feces to identify bat species from guano collected in field locations such as mines, caves, bridges, etc. The system takes advantage of DNA sequencing technology and an assay to look for genetic identifiers unique to different species using DNA barcodes. The sequences can then […]

Genetic regulation of horse conformation

In a new study published in Physiological Genomics, researchers explored the role of genetics in the conformation of Tennessee Walking Horses. In other words, how close each animal they sampled looked to an “ideal” Tennessee Walking Horse.  According to Kylee Jo Duberstein (Department of Animal and Dairy Science, University of Georgia), there are five criteria that are examined when evaluating the conformation of a horse. These include “balance, structural correctness, way of going, […]
