Each tiny leaf represents a single species and clicking on the leaf will […]

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 […]
