**Quebec City, Canada** – A team of researchers at the Institut national de la recherche scientifique (INRS) has developed a revolutionary new tool called RosHAB, designed to monitor the health of lakes in real time using genomic analysis. The tool offers a significant advance in protecting these vital ecosystems from the threats posed by climate change and human activity.
Lakes play a crucial role in our ecosystems, providing drinking water, supporting biodiversity, and driving economic activities. However, they are increasingly under threat from pollution, climate change, and other human activities. To effectively protect these valuable resources, researchers have been working on innovative ways to monitor their health.
RosHAB utilizes metagenomics, a powerful technique that analyzes the genetic material of all microorganisms present in a water sample. This allows researchers to identify changes in the lake’s microbiome, an indicator of its overall health.
“A single drop of water in a lake can harbor thousands, even hundreds of thousands of microbes,” explained Dr. Jérôme Comte, Associate Professor at INRS. “These microbes are the silent watchdogs of our aquatic ecosystems. RosHAB helps us listen to what they’re telling us about the lake’s health.”
Traditionally, lake health monitoring relied on optical microscopy, which requires significant time and expertise. RosHAB, however, offers a much faster and more efficient approach.
“The RosHAB tool can be used directly in the field, providing a profile of the lake’s microbiome within a few hours,” said Dr. Christophe Langevin, a PhD candidate at INRS. “This allows for rapid detection of potential problems, such as the proliferation of cyanobacteria, which can be harmful to human health and aquatic ecosystems.”
The researchers emphasize that implementing genomic tools in lake management requires training and adaptation for monitoring teams. However, the benefits of RosHAB, such as early detection of environmental threats and the ability to take preventative measures, make it a valuable addition to lake protection strategies.
“Understanding and monitoring the health of lakes through the microbes that live in them is essential for ensuring their preservation for future generations,” said Dr. Naíla Barbosa da Costa, a researcher at INRS. “RosHAB gives us a powerful new tool to protect these vital resources.”
