Researchers in the field of ecology have made a groundbreaking discovery, shedding light on the genetic makeup of entire populations through the examination of environmental DNA (eDNA). This remarkable advancement not only aids in tracking and preventing the spread of invasive species but also plays a crucial role in the conservation of endangered species, akin to the meticulous work of forensic investigators.
Ecologists have unveiled that the genetic material released by species into their surroundings holds the key not only to confirming the presence of these species but also to a wealth of information about the genetics of entire populations. This revelation has far-reaching implications, as it enables scientists to pinpoint the origins of newly invasive populations and take measures to curtail their expansion.
The innovation in environmental DNA (eDNA) analysis opens up exciting possibilities for safeguarding endangered and vulnerable species, offering hope for the preservation of biodiversity.
David Lodge, co-author of the study and director of the Cornell Atkinson Center for Sustainability, likened this progress to the work of forensic scientists at crime scenes. The meticulous research conducted in this study, published in the Proceedings of the National Academy of Sciences, demonstrates the successful application of this methodology in the field. Specifically, the researchers conducted field sampling of invasive round goby fish in various locations, ranging from the Great Lakes to the New York Finger Lakes.
In their investigation of the Great Lakes, the researchers collected water and tissue samples from round goby fish in 13 different locations spanning from Lake Michigan to Oneida Lake. Their eDNA sampling technique proved effective in detecting nuclear genetic variations, enabling a detailed analysis of genetic diversity and variations within species. This newfound knowledge is invaluable to natural resource managers as it empowers them to trace the source of invasive populations and implement strategies to prevent further invasions or mitigate their impact.
The breakthrough also offers a means to understand the demographics of imperiled species without the need to physically capture these rare and vulnerable creatures. Populations in decline often suffer from a loss of genetic diversity, and eDNA analysis may enable scientists to detect these declines early on. Kara Andres, the study’s first author and a postdoctoral fellow at Washington University in St. Louis, highlighted the significance of this advancement.
The study was authored by Kara J. Andres, David M. Lodge, and Jose Andrés, and its findings hold profound implications, particularly in marine environments. According to Jose Andrés, a Cornell Atkinson faculty fellow and a senior research associate, this breakthrough represents a significant stride in unlocking the full potential of genomics techniques when applied to aquatic eDNA samples.
Funding for this study was generously provided by the U.S. Department of Defense, the National Oceanic and Atmospheric Administration, the National Science Foundation, and Cornell Atkinson, highlighting the collaborative effort and importance of this research in various fields.

Frequently Asked Questions (FAQs) about eDNA Breakthrough
What is environmental DNA (eDNA)?
Environmental DNA, or eDNA, refers to genetic material that species release into their surroundings. This genetic material can be found in various environmental samples, such as water and tissue samples.
How does eDNA analysis help in tracking invasive species?
eDNA analysis enables researchers to not only detect the presence of species but also gather detailed genetic information about entire populations. This information helps in pinpointing the origin of invasive populations and devising strategies to prevent their further spread.
What are the applications of this eDNA breakthrough?
This eDNA breakthrough has wide-ranging applications. It aids in protecting endangered species by providing insights into their genetics and demographics. It also assists natural resource managers in understanding genetic diversity within species and in halting the movement of invasive species.
How does eDNA analysis benefit the study of imperiled species?
eDNA analysis allows scientists to understand the demographics of species in decline without physically capturing them. This knowledge is crucial for conservation efforts as declining populations often suffer from a loss of genetic diversity.
