The Maine Department of Agriculture, Conservation and Forestry (DACF) today announced $3 million in new PFAS Fund research grants to support Maine farms impacted by PFAS. While the vast majority of Maine farms are not impacted, DACF is currently working with 127 sites, ranging from small properties to large, diversified farms, to provide testing, financial assistance, research, and technical support that help farmers make informed decisions and continue operating safely.

Over the past five years, DACF has built robust programs of testing, expert guidance, and financial assistance to ensure safe food and continued farm operations on properties impacted by PFAS contamination. Most contamination stems from the historic use of wastewater sludge as an abundant, low-cost fertilizer, a practice banned in Maine in 2022. The presence of PFAS on agricultural land raises questions about how PFAS circulate through soil, water, plants, and animals; where PFAS accumulate within plants, animals, and animal products; and what management practices can be adopted to protect food safety and worker health. The PFAS Fund research grant program was established to help answer these questions.

DACF awarded a first round of research grants in Spring 2025 to fund projects investigating topics ranging from the use of biochar to immobilize PFAS to bioaccumulation and depuration in dairy sheep and understanding and managing the transfer of PFAS from soils to poultry and eggs.

 â€śThese new grants expand and accelerate agricultural PFAS research,” said DACF Commissioner Amanda Beal. “The results will help impacted farmers in Maine and across the country make informed decisions so they can continue to operate and thrive.”

For this round of applications, the PFAS Fund invited two categories of proposals: major grants focused on a broad set of research priorities to be carried out over two years, and targeted grants focused on narrower research questions that can be investigated over a shorter period. The Fund received a total of 31 grant applications requesting over $11 million. The application selection process was highly competitive. Each proposal was evaluated by a team of peer reviewers drawn from academia, State and Federal agencies, and the private sector.

The nine selected projects will focus on:

• Improving soil tests;
• Understanding plant, animal, and pollinator uptake of PFAS;
• Impact of PFAS on animal and pollinator health;
• Advancing predictive modeling of soil to livestock pathways;
• Whether plant uptake and PFAS leaching can be reduced through biochar;
• Possibilities for alternate crop production.

Photosynthesis is the oldest carbon-capture technology on Earth. For eons, plants have pulled carbon dioxide from the atmosphere and locked carbon — the building block of life on our planet — into their bodies and roots. 

In young forests, the widespread consensus is that this process rapidly pulls, or sequesters, carbon from the atmosphere. As forests mature, more trees start to die, releasing the carbon they captured in their wake. Carbon sequestration, the thinking goes, slowly stalls and old forests eventually release roughly as much carbon into the air as they capture.

Thirty years of measurements taken by 91±¬ÁĎ scientists at a remote 550-acre forest challenge this idea.

At Howland Research Forest, located about 30 miles north of Orono, Maine, in the towns of Edinburg and Howland, 98-foot towers rise above the spruce and hemlock canopy. They are topped by instruments that measure carbon dioxide flux — the exchange of the gas between the forest canopy and the atmosphere. The measurements are so precise that they can detect the breath of a technician working nearby.

What they have recorded is a carbon record of exceptional length drawn from a mature, undisturbed forest. The data generated here is reshaping how the world understands forests and their influence on climate. The towers on Howland have been collecting data since 1996, making them among the longest-running records of their kind in the United States, second only to Harvard Forest. 

These findings are used by scientists, educators and land managers worldwide, informing forest management, timber production, carbon budgets, conservation and policy. But the future of this research is uncertain. For decades, the Howland towers were supported through the federally funded AmeriFlux network. As research priorities shifted, that support was interrupted, putting the long-running record at risk. 

A recent $175,000 private gift to the 91±¬ÁĎ Foundation — equal to the site’s annual operating cost— has temporarily filled that gap, keeping the research running through next year. Without it, the towers would have gone offline this August, bringing 30 years of continuous monitoring to a standstill. 

“We have funds to continue another year. But our latest research, the student experience, the experimental work on managed versus unmanaged forests — all of it depends on the towers being operational. If the tower goes offline, we lose the context this monitoring data provides, and everything that has been built on it.” Shawn Fraver, Associate professor of forest ecology.

While the gift provides a one-year lifeline, it does not solve the underlying challenge. Sustaining this irreplaceable observatory and training ground for 91±¬ÁĎ students aspiring to become foresters, conservationists and researchers requires .

A living benchmark

Mature, unmanaged forests are exceptionally rare in New England. Centuries of timber harvest have reset the ecological clock across nearly every landscape. 

At Howland, the forest canopy is dominated by trees between 100 and 200 years old. Some are even older. They had already stood for centuries when Henry David Thoreau passed through central Maine on his way to Mount Katahdin in the 1840s.

A yellow birch documented in the forest’s permanent research plots dates to the mid-1600s — at least 367 years, the oldest of its species on record in Maine. Cedar and hemlock that sprouted in the 1700s stand alongside fallen logs in every stage of decay. Their slow decomposition is a critical part of the carbon cycle that researchers here are still working to fully understand.

Coarse woody debris — the fallen logs and standing dead trees so characteristic of old forests — are largely absent from managed landscapes. At Howland, it is everywhere. 

The forest is surrounded by active timber operations, which makes it something else: a control site. Without Howland as a baseline for what an unmanaged forest looks like, the comparisons that inform forest management across the Northeast would be far less meaningful.

The Northeast Wilderness Trust recognized that value in 2007, when it purchased the 550-acre site and permanently protected it as forever-wild. The protection came at a critical moment: the previous owner had considered resuming active management, which would have disrupted decades of research.

“We permanently protected Howland because ancient forests are rare and have so much to teach us,” said Shelby Perry, the Northeast Wilderness Trust’s wildlands ecology director. “Howland shows us the unique value of wild places amid managed landscapes. What researchers learn here informs forest policy at a global scale. Keeping this land wild and keeping the research going are inseparable.” 

For these findings, time is priceless

When a carbon flux tower was installed at Howland in 1996, it became a founding site of the AmeriFlux network, which has spread to more than 500 monitoring stations across the Americas. 

“We measure temperature, wind speed and direction, and the air’s carbon dioxide, water and methane concentration every tenth of a  second. That’s over 315 million data series a year,” says Roel Ruzol, 91±¬ÁĎ research associate and Howland Forest’s site manager. 

Ruzol keeps the towers running, coordinates access for researchers and works with Fraver to eliminate what he calls “noise,” or anomalies in the data created by rain, snow, power fluctuations or a bird perching near the equipment. They then convert these measurements into precise half-hour flux rates, that is, how much carbon the forest absorbs and releases. The findings are online for anyone to access.

“Science is a continual and ever-building process. The continuity of monitoring at Howland is a big part of what makes this data so powerful.” Chris Hettwer, 91±¬ÁĎ alum.

The Howland record is now 30 years old. The forest has stored, on average, nearly 3.5 tons of carbon dioxide per acre per year. That was not unexpected, but the long-term trend was surprising, even to the researchers who built the flux network. The rate of carbon uptake is increasing over time. This old forest has not plateaued; it’s accelerating sequestration.

“If you considered just the first 10 years, you would see a slight decrease and might conclude the forest was declining as a carbon sink,” said Shawn Fraver, associate professor of forest ecology at the 91±¬ÁĎ, who has conducted research at Howland since 2015. “However, when viewed over 30 years, we actually see an increase. That long-term view completely changes the story.”

The trend held through climate extremes. The 30-year record spans the warmest, wettest and driest years in the past 125 for Maine. Scientists do not yet know why, but the findings, which were in the Journal of Geophysical Research: Biogeosciences, provide the basis for experimental research that can provide actionable insights. 

Another study co-led by Fraver, whose research program is partially supported by the Maine Agricultural and Forest Experiment Station and the National Science Foundation, aims to identify the mechanisms by which forests switch from methane sources to sinks and back. Previous research showed that forest soils emit methane in wet conditions. Waterlogged soils favor the microbes that generate it. But those studies largely focused on landscapes that are known methane sources, ignoring sites like Howland that, depending on soil moisture, alternate between being a source and a sink. 

The documented source-sink switch at Howland has led to a National Science Foundation-funded project, now entering its final year, which attracted researchers from institutions across the country — San Diego State University, North Carolina State University, Arizona State University, and the Woodwell Climate Research Center in Massachusetts, as well as the 91±¬ÁĎ. The findings are expected to meaningfully revise how methane is accounted for in forest carbon budgets.

The data from Howland have been downloaded more than 16,000 times since being made publicly available in 2007. Researchers around the world have used Howland and the data gathered there to build climate models, calibrate satellite data, advise policymakers and teach the next generation of forest scientists.

A living lab for forest management

Howland’s scientific value extends beyond the conservation land itself. Three flux towers now operate across the area: two on Northeast Wilderness Trust land and a third on property managed by American Forest Management (AFM), a forestry consulting company that has been managing harvest activity nearby in recent years. “Not every forest company would be willing to cooperate with us on this. It’s a huge benefit to us as researchers,” Fraver said. 

The AFM tower, established in 2012, has been tracking carbon dioxide fluxes continuously through a period of active shelterwood harvest. With the Howland towers providing an unmanaged comparison site, researchers have a rare before-and-after opportunity that almost never presents itself in landscape-scale ecology.

A newly funded $243,000 study from the will extract maximum value from that natural experiment. Combining forest inventories, LiDAR-derived biomass estimates, ground and tower-level flux measurements and carbon modeling will give managers the most comprehensive picture ever assembled of how partial harvests affect the forest carbon budget.

“American Forest Management has always believed that good forestry and good science go hand-in-hand. Hosting the tower on our client’s land is one of the most tangible ways we can contribute to that.” said Jeremy Miller, Region Technical Manager at AFM and alum of 91±¬ÁĎ’s School of Forest Resources. “The NSRC study will give us an idea of how partial harvesting affects carbon dynamics in the short and long term.”

The results will give forest managers who want to incorporate carbon objectives into their planning, alongside timber production, a quantitative foundation to build on.

A proving ground for people and technology

Howland also serves as a key research site for 91±¬ÁĎ graduate students, along with undergraduate field technicians who spend summers gaining hands-on experience with advanced instrumentation and long-term ecological research methods. 

Chris Hettwer, who earned his master’s degree from the School of Forest Resources in 2025, said the opportunity to work at Howland helped draw him to Fraver’s lab. 

“Working at Howland was an instrumental experience that fundamentally shaped me as a scientist,” says Hettwer, who is now pursuing a Ph.D. at the University of Chicago. “In addition to learning the technical field skills for researching ecosystem processes, I gained a deeper understanding of how scientific research is conducted, communicated, and built cumulatively over time. Much of what I do now is grounded in what I learned at Howland.”

A network of approximately 150 permanent research plots distributed around the flux towers provides a training ground unlike any classroom. 

So does a 7.4-acre research plot, established by NASA in 1989 to ground-truth satellite instruments. This project led the site to be photographed from space more than anywhere else on the planet at the time. Every tree above 10 centimeters in diameter was mapped and measured. In 2015 and 2025, Fraver and his research team repeated the inventory and took core samples from 10% of the trees to track growth trends. 

That plot revealed the 367-year-old yellow birch. It also told the story of a forest shaped by centuries of disturbance: spruce budworm outbreaks, wind storms, selective harvests in the 1800s and the slow return of a mature forest carpeted with deadwood and moss. 

Howland is where emerging scientists and technology learn to read the forest.

One more year

Maintaining Howland’s flux towers, sensors and core infrastructure costs approximately $175,000 per year. That annual cost was historically covered through the federally-funded AmeriFlux network, but shifting research priorities have left the site without consistent support.

“Without this gift, the AmeriFlux tower would have shut down this August,” Fraver said. “We have funds to continue another year. But our latest research, the student experience, the experimental work on managed versus unmanaged forests — all of it depends on the towers being operational. If the tower goes offline, we lose the context this monitoring data provides, and everything that has been built on it.”

The recent private gift ensures operations through next year, but it does not establish a long-term solution. Keeping one of the longest carbon dioxide flux records in the Americas running, and preserving decades of continuous data, requires sustained annual investment.

“Science is a continual and ever-building process. The continuity of monitoring at Howland is a big part of what makes this data so powerful,” Hettwer said.  

The science at Howland is answering questions that matter in Maine and globally — how much carbon do mature forests sequester, how harvest practices affect forest-atmosphere interactions, and whether forest soils remove methane. These are not strictly academic questions. The findings help forest managers and policymakers make data-driven decisions in a changing world.

“The questions we are asking now about carbon, methane and how managed and unmanaged forests compare will offer critical insights for forest management in the coming decades,” Fraver said. “This forest is capable of providing those answers. It just needs the towers to keep running.”

School of Forest Resources / 91±¬ÁĎ Foundation

Moose are an essential part of Maine’s ecosystems, cultural identity and outdoor economy. As ecosystems rapidly change, moose face an increased risk of infection by parasites and disease. 

Researchers at the 91±¬ÁĎ are researching new ways to study and monitor the parasites that plague Maine’s moose in order to best help and manage the population. 

91±¬ÁĎ third-year Alden Falardeau of Saco, Maine, is leading the team in testing new methods of monitoring for parasites in moose. Advised by associate professor of animal health Pauline Kamath, Falardeau is focusing on lungworm (Dictyocaulus spp.) and gastrointestinal parasites. Lungworms weaken a moose’s immune system and hamper its ability to fight off external stressors like winter ticks. Gastrointestinal parasites also can weaken moose, making them more susceptible to other parasites, some of which  may cause emaciation. 

Falardeau, an animal science major, is investigating whether lungworm infections can be detected through DNA analysis of moose lung tissue, while identifying the gastrointestinal parasites present in their fecal pellets. Her team is testing these methods using samples from live captures and hunter harvests. Better detection can improve monitoring and understanding of parasite prevalence among moose. 

For the lungworm, the team extracted DNA from lung tissue samples. Researchers then evaluated them for traces of lungworm using polymerase chain reaction (PCR), which amplifies a unique section of lungworm’s DNA where signs of this parasite can be found.

“If we can verify lung tissue as a sample to detect lungworm, that could help with future research,” said Falardeau. “It can also help get the community more involved in research if we are able to use hunter harvested samples for identifying infections like lungworm.” 

Current research on lungworm in moose relies on visually examining moose lungs or waste, the efficacy of which can be dependent on a range of factors. Genetic data, in contrast, may allow scientists to identify traces of lungworm faster and with greater accuracy. 

Understanding what gastrointestinal parasites they should be looking for will allow for better detection and management in future. “Essentially, we are looking to identify and quantify the parasite eggs and larvae that are present in fecal samples,” said Falardeau. Crucially, this approach is not invasive, which is great for the moose. 

This project was made possible by funding from 91±¬ÁĎ’s Center for Undergraduate Research and has provided Falardeau valuable hands-on experience. 

“I’ve learned so much, from lab techniques to experimental design, and I’ve had the opportunity to be involved in meaningful conservation research,” he said.

This research is rooted in the One Health approach, which recognises that people, animals and the environment are interconnected. It also highlights the importance of monitoring wildlife disease for broader ecological well-being. 

As Maine’s moose remain a vital part of the state’s identity, efforts to better understand parasite impacts are critical to ensuring the long-term health of this iconic species and the ecosystems of which they are a part.

Last week our senior and national team placed 3rd behind Texas A&M University and Penn State University, two extremely competitive programs. Retired School of Food and Agriculture Professor of Animal and Veterinary Science, Dr. Dave Marcinskowski noted “Only twice before since 1998 has our national team placed third never higher.”

Dairy Challenge began in 2002 with the goal to develop tomorrow’s dairy leaders and enhance
progress of the dairy industry, by providing education, communication and networking among
students, producers, and agribusiness and university personnel. Every year students from across
the U.S. and Canada gather to apply their dairy knowledge skills, and the 91±¬ÁĎ
has been participating in this contest since its inception.

This year the contest was held in Sioux Falls, South Dakota with 282 student participants from
42 Universities across the U.S. and Canada. Representing 91±¬ÁĎ at the contest were Amanda
Allan majoring in Zoology, Cece Desautell, Felicity Gregware, Makayla Dingle, Opal
Beauchesne, and Riley McAllaster, majoring in Animal and Veterinary Sciences. In order to
prepare for this contest the students met weekly over the past year and reviewed dairy farm
benchmarks, learned how to interpret dairy records, and conducted a “mock challenge”. During
this “mock challenge” held in Deering Hall this past March 2026, the students evaluated a local
alumnus dairy farm, Taylor Dairy, and prepared a presentation with recommendations which was
presented to a panel of judges who were industry experts. This mock challenge emulated the
dairy challenge contest the students would participate in once in Sioux Falls.

At the contest held in South Dakota, juniors Makayla Dingle and Opal Beauchesne participated
in the Academy learning experience, while the seniors participated in the National Contest.
There were 4 dairy farms to evaluate, and this year 91±¬ÁĎ evaluated dairy farm B and
competed against 8 other Universities. Amanda, Cece, Felicity, and Riley each applied their
teamwork and expertise to evaluate a very well-managed 6,000 dairy herd that produced on
average 79 lbs of milk per cow per day and 5.5 lbs/cow/day of fat plus protein. The 4 91±¬ÁĎ
students put the dairy knowledge that they have learned from 91±¬ÁĎ professors, the staff and
cows at Witter Center, their peers and Maine dairy farmers to the test. The students were able to
earn 3rd place among the 8 teams that evaluated dairy farm B.

The 91±¬ÁĎ students were coached by Dr. Glenda Pereira, however, various members helped prepare and travel with the students including Dr. Dave Marcinkowski, Dr. Jessica Motta and Ethan Robertson. The students fundraised in order to travel to South Dakota and are thankful for the support from the College of Earth, Life and Health Sciences, cow level sponsors Phoenix Feeds of Maine, Poulin Grain, as well as calf level sponsors Cabot, and Jason Johnson.

Congratulations to the students for their success at the 2026 North American Intercollegiate
Dairy Challenge.

The first thing the students noticed at the 91±¬ÁĎ’s J. Franklin Witter Teaching and Research Center was the smell — fresh hay and something earthier, followed by the low hum of cows shifting in their stalls. Then came hesitation and, finally, curiosity, as small hands reached out to touch an animal many had only seen in books.

Dawna Kulakowski teaches first through third grade in Troy, Maine. For her, moments like this are the point.

“I think it’s important for kids in these grades to come to the farm and learn about agriculture here at the university, because they have a lot of this out in their own communities, and they might be interested in a career in this area in the future,” Kulakowski said. “I think a lot of these kids like hands-on learning to experience things in the real world.”

Public access is central to operations at Witter Farm in Old Town. It welcomes K-12 students, community residents, university groups and professional organizations to meet the animals, learn about the research and contribute to Maine’s agricultural industry.

On a cool March day, students from Troy Central School, including those in Kulakowski’s class, traded their desks for a behind-the-scenes look at a working agricultural operation just outside 91±¬ÁĎ’s campus.

Trotting horses, mooing cows and fresh hay greeted the group as their chatter and laughter filled the barns. The visit connected Maine’s traditional classroom education with the state’s agricultural industry — one that relies on a new generation to sustain it.

Guiding them through the barns were 91±¬ÁĎ student workers, who balance coursework with leading tours and completing their daily responsibilities on the farm — an example of the university’s learner-centered approach as an R1 research institution.

Their work gives visiting students a peer-led introduction to agriculture while reinforcing their own hands-on education.

“As part of the class, students come in during their sophomore year and start working on the farm doing all kinds of things. The highlight, though, is when they are assigned to a pregnant female cow,” said Chelsea Carr, livestock operations manager. “They get to be here for the birthing as part of their grade, and once the calf arrives, they get to name it as a group.” 

The Witter Center houses multiple operations, including Witter Farm, and serves as a hub for animal sciences and sustainable agriculture. As a primary facility for the Maine Agricultural and Forest Experiment Station, it integrates hands-on undergraduate and graduate education with high-level research.

The farm houses 78 animals and regularly welcomes school groups that engage directly with the animals and learn where their food comes from.

Many students also connect with the farm beyond their visit through the “Adopt a Cow” program, a Discover Dairy and New England Dairy joint initiative that features Witter Farm as one of several participating farms across New England.

“Every farm puts up two calves that get adopted by classrooms. I believe last year we were adopted by 600 classrooms of kindergarteners, and the adopted cows that we have this year are Darling and Doris. I’m sure that most of the tours on my schedule are here to see them,” Carr said.

Through this yearlong virtual initiative, educators can bring the world of farm life into their classrooms. By adopting a calf from a New England dairy farm, students can follow a specific calf’s development over the course of the school year. This immersive experience is supported by complimentary educational materials from Discover Dairy, helping students understand dairy farming and how milk reaches their tables.

“We send updates, photos and videos of our adopted calves to Discovery Dairy, who then shares this information with the participating classrooms that have adopted our calves,” said Patricia Henderson, Witter Farm’s superintendent.

Beyond traditional farm work, Witter Farm reflects the modernization of agriculture through its robotic milking barn.

“We put in the VMS300, a voluntary milking system, about a year ago in March. It’s a robot that milks the cows without people having to do it. The cows can come in whenever they want, and the robot will milk them, clean the teats and collect a whole bunch of data for us,” Henderson said.

The farm’s openness is intentional. Leaders say inviting the public in and encouraging questions helps challenge misconceptions about agriculture.

“I think there’s a lot of stigma behind dairy farming, so opening our tours to any and all questions is important for opening farms like this to the public and growing their knowledge of our industry,” said Riley McAllaster, a senior in the animal and veterinary science program with a pre-veterinary concentration.

That effort is tied to a broader concern: fewer people are entering the agricultural workforce.

“I hope these tours spark an interest in agriculture for these kids. With our new technology, like the robot barn, I hope people will understand that this is a modern, informing industry,” Carr said. “I want more people to be aware of the many agricultural jobs beyond working as a farmer, including research roles. Renewable farming is a growing industry, and it is full of jobs that need to be filled, and I hope these kids realize these opportunities early on.”

Understanding the source of stress and disease can be difficult, especially if the subject of stress is a fish, or even thousands of fish. 

Detecting and diagnosing stress and disease is a major challenge for aquaculture farms, where keeping fish happy helps them thrive. In fish, stress can be hard to detect before it becomes problematic, and testing for the source of stress usually requires physical examination or biopsy, which are invasive and often lethal.

An international team of researchers led by the 91±¬ÁĎ is trying to change this by developing noninvasive, rapid tests that can detect stress and disease without touching the fish, just the water in which they swim. 

Scientists from 91±¬ÁĎ, Dublin City University (DCU) and Queen’s University Belfast, plan to develop a new testing method that uses environmental RNA (eRNA) so aquaculture farmers can monitor fish health more quickly, efficiently and humanely.

“The goal is to get a window into the physiology of the organisms, their health in particular. By looking at what RNA is being shed from their tissues into the environment, eRNA can give us insights into what the fish are doing as biological machines,” said Michael Kinnison, 91±¬ÁĎ professor of evolutionary applications and director of the Maine Center for Genetics in the Environment.

Key to this research is a difference between environmental DNA (eDNA) and RNA. DNA within an organism’s cells does not change over an organism’s life or cell to cell — it is the blueprint of life. In contrast, RNA is what turns a general DNA blueprint into the diverse building blocks and processes that give various cell types and tissues their function. Because of this, the RNAs that an animal produces varies depending on where it is in its lifecycle, what is happening in its environment and what processes are underway in its body, such as stress or disease. When animal cells are naturally shed into the environment, their DNA and RNA become eDNA and eRNA, but the eRNA does not last as long. While this means eRNA is harder to detect, it also has the potential to provide a near real-time window into an animal’s condition. 

A major challenge for researchers is linking particular eRNA signals to specific stressors, but pilot data and recent research by others suggest it is possible. For example, researchers in Japan successfully . 

“This hasn’t been done for salmon yet, and it’s just exciting because it means that if we could use these RNAs, we wouldn’t have to kill fish to biopsy them. We might be able to figure out and treat disease before it gets really bad,” said Erin Grey, 91±¬ÁĎ assistant professor of aquatic genetics.

In addition to identifying what eRNA signals are tied to salmon stress and disease, the team will use CRISPR-Cas diagnostic technology to develop rapid tests for those eRNA signals. Similar to a COVID test, these tests could allow someone at an aquaculture farm to sample water and quickly identify issues. Early intervention in salmon farming has the potential to improve treatment of fish, allow for more targeted treatment and avoid economic damages that run into the hundreds of millions annually. 

The project is starting with small controlled systems like tanks, and as research progresses, the team hopes to expand to more open systems like net pens. Fish will be sampled in Maine and Scotland at 91±¬ÁĎ’s Aquatic Animal Health Laboratory and the University of Aberdeen’s Scottish Fish Immunology Centre. The initial focus will be on heat stress and furunculosis, two common challenges experienced by salmon farms. Researchers are working with the salmon aquaculture industry and fish health diagnostics providers to further identify what other pathogens or stressors would be most impactful for further investigation. 

While eRNA technology is in a nascent stage of development, this project brings together the expertise needed to rapidly advance its potential and put it in the hands of food producers. 

“Environmental RNA technology is still at an early stage of development, but its potential is significant. At Queen’s, we will apply advanced genomics and bioinformatics approaches to identify the molecular signatures of stress and disease in salmon,” said Paulo Prodöhl, professor of population and evolutionary genetics from the School of Biological Sciences at Queen’s University Belfast. “By working closely with colleagues at DCU and 91±¬ÁĎ, we aim to ensure that this technology moves from proof-of-concept to practical application for the aquaculture industry.”

This research is made possible by ,  a tri-jurisdictional collaboration between the United States, Ireland and Northern Ireland which was officially launched in 2006. Under this program  the international project team receives  funding from the Agriculture and Food Research Initiative from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA NIFA), the Department of Agriculture, Food and Marine (DAFM) in Ireland, and the Department of Agriculture, Environment and Rural Affairs (DAERA) in Northern Ireland.

“This funding is a testament to the power of interdisciplinary research,” said DCU School of Biotechnology professor Anne Parle-McDermott. “By combining our molecular expertise with the knowledge and expertise at 91±¬ÁĎ and QUB, we are uniquely positioned to tackle one of aquaculture’s biggest challenges.”Contact: Daniel Timmermann, daniel.timmermann@maine.edu
