Wildlife, fisheries and conservation biology

The wildlife, fisheries and conservation biology program has more than doubled in enrollment over the past two decades, reflecting sustained interest in conservation and natural resource careers.

The curriculum emphasizes field-based learning. More than half of courses include outdoor labs, and students complete a required immersive field experience in Downeast Maine that is frequently cited as a defining part of their education. More than 80% of undergraduates report that fieldwork influenced their decision to enroll.

Students gain experience through field surveys, internships and research. About 70% complete field experiences, and more than half participate in faculty-led research. Faculty and students have also produced more than 140 peer-reviewed publications and secured nearly $16 million in research funding during the past five years.

Among graduates, 95% are employed or enrolled in graduate school, and 82% work in natural resource fields.

Animal and veterinary sciences

Enrollment in 91爆料鈥檚 animal and veterinary sciences program has increased since before the COVID-19 pandemic, reflecting demand for careers in animal health, veterinary medicine and agriculture.

The program prepares students for careers in veterinary medicine, research and agriculture-related fields. About 20% of graduates continue to veterinary or medical school, while others enter the workforce directly.

Students gain hands-on experience at the university鈥檚 J.F. Witter Teaching and Research Center, where they work with animals in applied settings and develop practical skills.

All students also participate in research with faculty on topics including animal health, environmental systems and disease. Faculty say the program is structured to support both exploration and career preparation as workforce demand continues to grow.

A group of chemicals known as PFAS have become a growing concern for human health, agriculture and the environment. Because they resist breaking down, these 鈥渇orever chemicals鈥 can accumulate in soil, water and food systems and expose people to a range of adverse health conditions.

From nonstick cookware and disposable tableware to everyday items like toothbrushes, these oil- and water-repellent chemicals became widespread in the late 20th century. Today, communities across the country are grappling with the residue they鈥檝e left behind.

Maine has emerged as a national leader in responding to PFAS contamination, advancing policies aimed at protecting farms, ecosystems and public health. Researchers at the 91爆料 are working to understand how PFAS moves through soil, crops and livestock; develop technologies to break it down; and design sustainable materials that could replace it in everyday products.

On this episode of 鈥The Maine Question鈥 podcast, host Ron Lisnet speaks with 91爆料 researchers Jean MacRae, Christina Murphy, Caroline Noblet and Rachel Schattman about how their work, spanning engineering, economics, agriculture and conservation biology, is helping communities confront PFAS and chart a cleaner path forward.

At the 91爆料鈥檚 Darling Marine Center, student researchers have launched a new project this summer to investigate the feeding habits of striped bass along the coast of Maine. 

The project is led by Abby Remick, a first-year graduate student in the lab of Michelle Staudinger, associate professor of marine sciences. Student researchers will collect striped bass samples and analyze them for their diet and nutrient content. Using this data, the team will assess the impact of bass feeding habits on a variety of coastal fishes and invertebrates, information which can support balanced management decisions that protect both predator and prey populations. 

To support their work, Remick and her colleagues are asking anglers throughout Maine鈥檚 coast to donate instead of discarding what remains of their striped bass catch after filleting. The donated samples from fish within the legal slot will be used for scientific analysis, both reducing waste and supporting research. The student researchers are also seeking licensed boat operators who are willing to bring them aboard to conduct additional sampling of striped bass catch. 

Contact Remick at 401.651.1034 or abrielle.remick@maine.edu to participate. More information about the research project and what students need is available online.

鈥淭he ocean is large, and our understanding of it is patchy. By inviting industry professionals and local communities to participate in research, the capacity for a well-rounded understanding of culturally and ecologically important marine species enriches and expands our knowledge of Maine鈥檚 coastal communities,鈥 Remick said. 鈥淗elp us study striped bass, one stomach at a time.鈥

In Maine, striped bass are top predators in estuarine and nearshore ecosystems, said Remick. Their feeding habits include forage fish such as river herring, menhaden, mackerel, juvenile groundfish and lobster. 

鈥淢ore than just a prized catch, striped bass are an integral part of Maine鈥檚 marine ecosystems, connecting ocean and riverine habitats as they migrate. Their seasonal presence speaks to the resilience of nature and the importance of careful stewardship in preserving Maine鈥檚 rich coastal heritage,鈥 Remick said. 鈥淯ltimately, diet studies can guide us towards a more ecosystem-based fisheries management style that better contributes to multi-species conservation in the Gulf of Maine.鈥 

While striped bass diet is well known along much of the mid-Atlantic coast, Remick said Maine鈥檚 waters have a surprising lack of data. Foraging ecology, the study of how animals search for and consume food in their environment, helps scientists at the Maine Department of Marine Resources (DMR) better understand the state鈥檚 coastal food webs and inform fisheries management. 

Close collaboration with the Maine DMR has built relationships foundational to this project, which will help Remick and the other student researchers integrate this data into stock assessments aligned with the department. Remick鈥檚 advisor, Staudinger, said the DMR鈥檚 marine resource scientists have helped Remick connect with the recreational fishing community through the , a national survey network through the National Oceanic and Atmospheric Administration.

Prior to joining the Darling Marine Center, Remick worked as an at-sea fisheries observer on commercial ground fishing vessels in the Northeast collecting bycatch data. The experience propelled her into fisheries research, where she gained inspiration for collaborative science that extends outside of the lab and classroom. Beyond this project, Remick is looking to partner with more local anglers, charter boat captains and tackle shops in coastal Maine to broaden data collection.

Scarce snowpack hindered snowmobile recreation in Maine last winter, squeezing businesses that count on the sport to draw tourists.

The 91爆料 released an on the economic contribution of snowmobiling in Maine, revealing a significant decline in impact for the 2023-24 season. According to the study, snowmobiling generated an estimated $582 million in economic contributions during the 2023-24 season, a sharp drop of $128 million compared to the previous year.

Snowmobiling is a cornerstone of Maine鈥檚 winter tourism industry, drawing enthusiasts from across the region. The sport supports local businesses, from lodging and restaurants to equipment retailers and repair shops, particularly in rural communities.

鈥淲ith the economic contributions of snowmobiling nearing $710 million in strong seasons, this activity is vital to Maine鈥檚 economy and identity,鈥 said Jessica Leahy, lead author of the report and professor of human dimensions of natural resources at 91爆料鈥檚 School of Forest Resources. 鈥淭he recent decline highlights the need for adaptation, particularly as climate change continues to affect snow conditions. Snowmobilers may need to change when and where they go, and businesses will also want to consider how they can change too.鈥

The findings underscore the financial toll of poor snow conditions and declining snowmobile registrations. The researchers caution that the 2023-24 estimates may underestimate the true economic decline. Poor snow conditions likely reduced the number and duration of snowmobile trips, impacting spending on lodging, fuel, dining and equipment.

鈥淜eeping current reports like the economic impact studies helps our State of Maine Snowmobile Program with short-term planning. However, we like to look at longer trends over ten years and can better plan that way,鈥 said Joe Higgins, snowmobile program coordinator for Maine鈥檚 Bureau of Parks and Lands.

The study builds on a that examined the 2018-19 season, when snowmobiling contributed an estimated $607 million to Maine鈥檚 economy 鈥 equivalent to $746 million in 2024 dollars. Updated results for the 2022-23 season indicate an economic contribution of $710 million in 2024 dollars, buoyed by favorable conditions and robust participation. However, the 2023-24 season saw a marked decline in snowmobile registrations and trip activity, leading to a significant decrease in economic impact.

鈥淟ike any outdoor recreational activity, we鈥檙e at the mercy of the weather. We can have very good years with lots of snow and other years, like last year with low snow which as noted impacts jobs, restaurants, hotels and other services,鈥 Higgins said. 鈥淭he Bureau of Parks and Lands fully understands the economic impact and importance of outdoor recreation to communities and will continue planning around climate changes.鈥  

The updated analysis used spending profiles from the 2018-19 season, adjusted for inflation, to estimate the economic contribution of snowmobiling for the 2022-23 and 2023-24 seasons. Spending data accounts for both resident and non-resident snowmobilers, incorporating costs such as trip-related expenses and equipment purchases. Snowmobile registration numbers were used as a baseline for calculating total contributions, with adjustments made for inflation to reflect current economic conditions.

Mindy Crandall, co-author and associate professor at Oregon State University, noted the importance of consistent updates to reflect evolving trends. 

鈥淭his method allows us to track economic contributions year over year, but significant changes in behavior or conditions 鈥 such as those seen during the pandemic or due to climate change 鈥 could require comprehensive re-evaluations,鈥 she said.

The report suggests continuing this methodology through the 2027-28 season, after which a comprehensive survey of snowmobilers will be necessary to account for shifts in spending behavior and other evolving factors.

This report is an update to the comprehensive 2020 study conducted by 91爆料, which analyzed the spending patterns and economic contributions of snowmobilers during the 2018-19 season. The report was funded by the Maine Snowmobile Association, with support from the Maine Department of Agriculture, Conservation & Forestry.

Ask anyone who frequents the forests of New England and they will likely speak of unwelcome companions 鈥 ticks.

Blacklegged ticks are expanding their range and rising in numbers, infecting people with pathogens that cause conditions like Lyme disease and babesiosis. Climate change is frequently blamed, but researchers have noticed another man-made problem may be helping the pests spread. Invasive forest plants like buckthorn, honeysuckles and Japanese barberry create dense, damp thickets where surveys show ticks love to lurk. 

With a new opportunity to turn the tide on ticks in sight, three 91爆料 researchers secured a from the National Science Foundation to test if controlling unwelcome forest plants also reduces densities of ticks, and how landowners can best apply and share that information. Graduate and undergraduate student researchers will be recruited to support the project. 

Landowners 鈥 whether suburban homeowners or small woodland owners 鈥 make choices about how to manage invasive plants and ticks, but typically address them separately. Forest ecosystems are complex and continually change, making the best strategies for managing these challenges feel elusive. To help landowners, the project will develop actionable recommendations on forest management as well as best practices for sharing that information, and establish a network for spreading these ideas. 

鈥淭his research uses the connection between human health and our environment to combat multiple issues simultaneously,鈥 said Allison Gardner, an associate professor and medical entomologist at 91爆料 who is one of the project鈥檚 principal investigators. 鈥淏y developing actionable strategies to help landowners target invasive plants, we can also reduce habitats where ticks thrive and tick-borne diseases spread 鈥 a win-win for people and the environment.鈥

The project unites Gardner鈥檚 entomology expertise with social, behavioral and environmental scientists, enabling them to seamlessly translate field research into change in the forest. Other principal investigators include 91爆料 professors Jessica Leahy, a human dimensions of natural resources scholar and forester, and Timothy Waring, an evolutionary and behavioral scientist; as well as William Landesman, an associate professor who studies microbiology and tick-borne pathogens, and Kristen Ross, a plant and restoration ecologist and assistant professor; both of Vermont State University.

鈥淥ne problem is that it鈥檚 hard, even for scientists, to figure out the best approach. So there鈥檚 no guarantee that landowners are going to learn effective solutions either. We will study how landowners learn forest management practices from one another with an eye to finding and spreading these win-win approaches,鈥 said Waring.

The five-year study will survey tick densities and test management techniques in Maine and Vermont. Researchers will also explore how landowners manage their woods for both ticks and invasive plants, and how they learn 鈥 or fail to learn 鈥 best practices from each other. They will then take what they learned and teach landowners grappling with the unwelcome duo best practices for simultaneously managing invasive plants and ticks. The project will foster further dissemination of this research by establishing a peer-to-peer outreach program called Forest Landowner Education & Research Network (Forest LEARN). Forest LEARN will equip landowners as ambassadors for science so they can share best practices for invasive plant and tick management with their neighbors and communities.

Private and public land managers who wish to contribute to the tick-forest research or join the LEARN network should email jessica.leahy@maine.edu. The Forest LEARN program will provide tailored training and resources to empower landowners to manage their woodlands more effectively and share strategies with their peers.

鈥淭his is more than a research project 鈥 it鈥檚 a community effort to create healthier landscapes and protect Maine鈥檚 residents,鈥 said Leahy. 鈥淏y collaborating with landowners and developing peer networks, we鈥檙e building the capacity for Maine to thrive in the face of emerging challenges.鈥

The American woodcock is a well known shorebird found across eastern North America. Each year, they migrate from overwintering locations in the southeastern U.S. to breeding locations across the northeastern and midwestern U.S. and southeastern Canada.

To gather data on the woodcock鈥檚 migration, a team led by faculty at the 91爆料 has collaborated with 15 different state natural resource agencies, federal agencies in the U.S. and Canada, a number of conservation nonprofits and two other universities.

The Eastern Woodcock Migration Research Cooperative was co-founded by 91爆料 avian experts Erik Blomberg and Amber Roth, both faculty at 91爆料鈥檚 Department of Wildlife, Fisheries and Conservation Biology, which Blomberg chairs. Roth also holds an appointment in 91爆料鈥檚 School of Forest Resources.

Researchers use GPS trackers affixed to the birds to study their movement throughout the year. Widespread collaboration has generated a dataset with nearly 700 individual woodcock tracked by GPS. Through their migrations, these birds have flown to nearly the full extent of the species鈥 range in North America, through 32 states and seven Canadian provinces.

Graduate and undergraduate 91爆料 students used data from the project, which is supported by the Maine Agricultural and Forest Experiment Station through the College of Earth, Life, and Health Sciences, for various studies. A former postdoctoral fellow with the project, Sara Clements, evaluated migration strategies and . Alexander Fish, who completed his Ph.D. in 2021, compared the timing of woodcock migration with the annual hunting seasons for the species and .

If you鈥檝e felt the familiar itch of browntail moth rash, seen the grayish-green needles of an infested hemlock or watched as woodpeckers bore into ash trees for a meal hidden beneath the surface, you鈥檝e experienced the devastating effects of non-native pests. Browntail moth, hemlock wooly adelgid and emerald ash borer are only three of the many pests that have wreaked havoc on Maine鈥檚 public health, economy and ecological landscape. 

A photo of a person writing on a plastic bag

Angela Mech, assistant professor of entomology at the 91爆料, is an expert on forest insects, specifically the invasive ones.

鈥淲hen talking about non-native insects that invade North America, the first time something is detected, those of us who work in the field hold our breath, because we have no idea if it鈥檚 going to be the next emerald ash borer, the next browntail moth, the next really bad thing,鈥 Mech said.

Mech has been grappling with how to predict which of these invaders may cause the next ecological disaster since 2016, when she was a postdoctoral researcher at the University of Washington. 鈥淲hy do some species do all these bad things? But the majority of them don鈥檛?鈥 Mech said, posing the same question that brought the group together initially. 

That question inspired Mech and her collaborators to develop a tool to predict the risk a non-native insect may pose if introduced to a certain area. Its name is, fittingly, pest predictor. 

The is the result of seven years of work by Mech and across the United States, with funding from Davey Tree Expert Company, the U.S. Geological Survey and the USDA Forest Service. Davey Tree Expert Company also acts as host for the tool. It launched in fall 2023 and uses input data determined by hypotheses to predict the probability of a non-native insect becoming a high-impact pest. It is hosted by i-Tree, a peer-reviewed software suite from the Forest Service that provides urban and rural forestry analysis and benefits assessment tools.

To create the tool, researchers compiled factors that may affect non-native insects鈥 ability to reshape a forest. Traits of the insect, traits of the North American host trees, insect evolutionary history and tree evolutionary history were each evaluated and then combined into a single model that predicts the risk a given insect poses for each North American tree species.

鈥淲e had to collect all this data to test those hypotheses,鈥 Mech said. 鈥淥ur conclusion was that, like every recipe, there are multiple ingredients, and so there was no single answer. It was actually multiple things. Sometimes it does have to do with the host and then it also has to do with evolutionary history. It鈥檚 about having these things lined up in the right way. It鈥檚 the recipe for destruction.鈥

A photo of a pest trap with bugs in it

Nathan Havill, a research entomologist with the Forest Service鈥檚 Northern Research Station was one of many of the pest predictor鈥檚 key developers. Havill works in the agency鈥檚 invasive species unit, concentrating on pests that impact trees and forest ecosystems. He focuses mainly on genetics and evolutionary biology, examining new pests to find out more about where they came from and their natural enemies that may have the potential to stem their spread. 

A photo person looking a pest trap

At present, Havill is gathering information about approximately 70 species of non-native insects. His intent is to input this information into the model, which can help determine if any have the potential to become high-impact pests.

鈥淥ftentimes, when a non-native insect gets introduced and it rears its ugly head as a pest, it鈥檚 a scramble to figure out what it is and where it came from. During the time when we鈥檙e trying to figure out that basic information, the pest is killing trees,鈥 Havill said. 鈥淚f we can focus our efforts on particular groups of insects and study those before they get here, then we can reduce some of our time trying to figure out those basic elements. That鈥檚 really the benefit that I see for this tool: being able to focus the research and make it more efficient to study those insects that have a higher probability of becoming mega invaders.鈥

Havill also noted that the use of a tool of this kind creates a more efficient and cost-effective workflow for eradicating pests once they arrive.

鈥淥ftentimes we鈥檙e caught by surprise, and by the time we realize that an invasive insect is a serious pest, it鈥檚 spread so much that eradication is really difficult. If we can recognize and understand what the pests are earlier, and be able to identify them and find them earlier, then we can potentially eradicate them before they spread and become pervasive pests,鈥 Havill said.

Mech and Havill both see this tool as a proactive solution to the reactive work they both do daily. With the tool鈥檚 ability to help predict the next ecological disaster, their next step is to spread the word and connect with researchers worldwide to determine how it can make an impact in their own countries.
