DNA breakthrough detects genetic diversity of invasive fish

September 13, 2023 sarah JonasResearch Results

Ecologists have demonstrated that the genetic material that species shed into their environments can reveal not only the presence of the species but also a broad range of information about the genetics of whole populations — information that can help scientists trace the source of a new invasive population as well as prevent further invasion.

A team of scientists led by the Wildlife Conservation Society (WCS) and Appalachian State University used environmental DNA (eDNA) to document the breadth of high-alpine biodiversity present on Earth’s highest mountain, 29,032-foot Mt. Everest (8,849 m).

What’s down there? WHOI study shows environmental DNA is a reliable way to learn about migration from the ocean twilight zone

November 1, 2021 sarah JonasResearch Results

The mid-ocean “twilight zone” holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult.
