Big Fish, little fish: the ups and downs of Yellow Perch and Northern Pike in the Great River

Dr. Mary Ann Perron, Mitacs Postdoctoral FellowThe River Institute & University of Ottawa 

As River People, we all love and care for our fish. They are a key part of livelihoods and ways of life along the Great River. The St. Lawrence River has experienced major human-driven degradation that has fundamentally altered the food web. Yellow Perch are a sentinel species in the region with a culturally rich history. Northern Pike are top predators in the ecosystem and contribute to its natural regulation and equilibrium. The importance of both species, and their responses to environmental change, make them good indicators of the health of the Upper St. Lawrence River. As part of the Great River Rapport, we explored abundance indicators of Yellow Perch and Northern Pike in the Upper St. Lawrence River along with the major drivers of trends in abundance over the past 100 years. Join us on September 7th at 7pm at Schnitzel’s in Cornwall to learn more about these important fish! 

Dr. Mary Ann Perron completed her BSc at Laurentian University in Biology with a specialization in Restoration and Conservation Ecology. She then went on to complete her PhD in Biology at the University of Ottawa, specializing in freshwater ecology with a focus on wetland ecosystems and dragonfly science. Dr. Perron joined the River Institute in 2020 as a Mitacs postdoctoral fellow where she leads the scientific component of the Great River Rapport. She is currently leading a team of scientists to complete a series of technical reports on the 35 ecological indicators for the project.

Stories of Coastal Resistance and the Climate Crisis

Philip A. Loring, author of Finding Our Niche and associate professor at the University of Guelph 

Coastal communities are often described as being on the front line of climate change impacts. In this talk, Loring explores also how they can be the front line of active and innovative responses to climate change. He explores the deeply rooted but often overlooked injustices involved when communities are asked to be resilient or to adapt to changes and disasters over which they have no control or responsibility. With lessons from how fishing communities responded to the first year of closures of COVID19, Loring explores opportunities for communities to “bounce forward” in the face of change, mitigating carbon dioxide while also reducing vulnerability and building community well-being.

Dr. Philip Loring is an Associate Professor in the Department of Geography, Environment, and Geomatics at the University of Guelph, where he holds the Arrell Chair in Food, Policy, and Society. A human ecologist, his work focuses on the intersection of sustainability, food systems, and social justice, primarily in coastal settings. An avid science communicator, Loring emphasizes writing, film, and other forms of storytelling to reach diverse audiences. His book, “Finding Our Niche”, won a gold medal from the Independent Publisher’s Awards and a silver medal from the Nautilus Book Awards, and his TEDx talk, “No More Heroes”, has received over 100,000 views.

Breeding Bird Atlases: Putting Canada’s Birds on the Map 

Dr. Catherine Dale, Newfoundland Breeding Bird Atlas Coordinator, Birds Canada

Having solid baseline data about the distribution, abundance, and health of bird populations is essential for sound conservation and management decisions: we can’t know what we’re losing if we don’t know what’s out there! Breeding bird atlases are multi-year citizen science projects that aim to provide this baseline data by combining the efforts of scientists and birders to map the bird species breeding in a province. The data collected are used by governments, academics, industry, and conservation experts, and inform decisions about land and resource management to minimize the impact of development on biodiversity. Currently, there are 2 breeding bird atlases under way in Canada: the Ontario and Newfoundland Atlases. Come out to this talk to learn about how these ambitious projects are set up, what we can learn from them, and how you can join the fun and survey birds for science! 

Bio: Dr. Catherine Dale began her ornithology career studying tree swallows near Chaffey’s Lock, Ontario as an undergraduate student at Queen’s University, and has been fascinated by birds ever since. She completed a PhD in Biology at Queen’s in 2018, studying migration patterns of Western Bluebirds, and is currently employed by Birds Canada as the Coordinator of the Newfoundland Breeding Bird Atlas. 

She believes strongly in the importance of citizen science and loves that her job brings together two of things she’s most passionate about – birds and science outreach. Since her move to St. John’s, she has been eagerly exploring the woods, cliffs, and bogs of Newfoundland, and learning all about the birds of her adopted home.

Rethinking urban planning: Why sustainable cities are important

Angela Parker – Sustainability Project Coordinator, City of Cornwall 

Urban growth shows no signs of slowing and more than half of the world’s population live in cities. This is set to rise over 70% by 2070. Urban infrastructure today is built for yesterday’s climate, not tomorrow’s. If the future is going to be different because of climate change, then the past isn’t so helpful. Systematically integrating technological, nature-based, and social solutions is key. Strengthening urban climate resilience and lowering greenhouse gas emissions is crucial and needs to be considered in transportation and buildings, the two main emitters of greenhouse gases. This talk will discuss cities as a cause of and solution to climate change, and how the City of Cornwall, Ontario is taking action.

Angela holds a master’s degree in Geography, Urban and Environmental Studies from Concordia University, Montreal. Her research focused on human/animal interactions within particular spaces, including road ecology. She has since expanded from that research to contemplate how human-induced extreme weather events are impacting both domesticated and feral nonhuman species. 

She brings this knowledge and passion, as well as a decade of communications and outreach experience, to the City of Cornwall as the new Sustainability Project Coordinator. Her role at the City involves outreach for the community as well as implementing initiatives for current and future projects to ensure that the City mitigates greenhouse gases and becomes resilient to climate change. 

Native Insects and Invasive Molluscs:

Rivals for Domination of the Depth

Dr. David Bruce Conn

A river as large and complex as the mighty St. Lawrence entails a diversity of underwater habitats, each supporting a distinctive biota. The vast size and significant depth of the river, combined with frequent turbulence and powerful currents, create a dynamic environment that is difficult and hazardous to study. For 35 years, our teams have undertaken numerous projects, employing a range of methodologies to shed light on the animals that dwell on the river’s bottom and in many cases define the living communities of the deep. From scuba diving, to dredging from research watercraft, to examining animals that attach to navigational buoys, among other techniques, we have pieced together a growing body of information on the invertebrate bottom biota of the upper river, from Lake Ontario to Montreal. This benthos is very diverse, but in many locations is dominated by a small number of keystone species that define the communities of the deep. From native species such as filter-feeding caddisflies, to invasive species such as zebra mussels, this talk will explore the ever-changing life in the river’s depths.

Dr. David Bruce Conn is Gund Professor of Biology at the Berry College One Health Center, Associate of Invertebrate Zoology at Harvard University Museum of Comparative Zoology, and Senior Scientific Advisor on international issues for the U.S. State Department, while serving as a member of the White House national security subcommittee on foreign animal threats.

While a professor at New York’s St. Lawrence University, he chaired the multisectoral international St. Lawrence River Zebra Mussel Task to mitigate the spread of invasive European mollusc through Great Lakes system. He is an editor for several scientific journals, has been president of three international scientific societies, and is currently Vice President of the global INVASIVESNET organization. Prof. Conn continues to build collaborating teams around the globe, with research spanning many areas of the life sciences. His work on the St. Lawrence River began in 1985, with plans to continue into the future.

The FINS project: Little Fish, Big River 

Matt Windle

In 2015 the River Institute and the Mohawk Council of Akwesasne’s (MCA) Environment Program staff began a project with a simple goal: to describe the nearshore fish populations of the Akwesasne and Cornwall section of the St. Lawrence River. Under the moniker FINS (Fish Identification Nearshore Survey), the project was initially designed to fill in knowledge gaps and address community concerns regarding the state of small fish populations in the area, which were perceived to be declining. Since 2015 the FINS Project has grown considerably in terms of geographic scope, research focus, technological tools, and collaborative relationships. It has developed into a platform that has provided numerous local and regional benefits: high quality training opportunities for young professionals and volunteers; continuity of research and strengthening working partnerships between the River Institute and the MCA; filling in critical knowledge gaps for species at risk; monitoring the spread of aquatic invasive species (AIS); developing the use of new technologies such as Remotely Piloted Aircraft Systems (RPAS) and environmental DNA (eDNA); providing public outreach and education on fish species and their habitats; providing opportunities for university graduate students and collaborations; and identifying areas for restoration and conservation activities. To date the project has surveyed over 200 sites from Kingston to Montreal and documented over 155,000 fish from 67 species, and has built one of the largest and most unique baseline datasets of the Upper St. Lawrence River nearshore habitats. This presentation will focus on the highlights, successes and challenges of the FINS Project, with insights into plans for future directions and goals.

Matt is a biologist at the River Institute with experience in environmental science, freshwater ecosystem ecology, spatial analyses, contaminant analyses, and Remotely Piloted Aircraft Systems (RPAS).

He completed a BSc in environmental science from Queen’s University, and a M.Sc. in Biology at Memorial University of Newfoundland. In addition to his work as a Research Scientist at the River Institute, he is also a professor in the Environmental Technician Program at St. Lawrence College. He has certifications for open water SCUBA, the Ontario Stream Assessment Protocol (OSAP), Royal Ontario Museum (ROM) fish identification workshops, advanced operations and flight reviewer status for RPAS from Transport Canada, and the Ontario Wetland Evaluation System (OWES). 

The secret life of the American eel

Courtney Holden

Like many species, when eels are captured in the natural environment, much of their life history is a black box. Capture location can indicate recent habitat use, but for long-lived migratory fish that use multiple habitats across a broad geographic range, much of the fish’s interaction and experience with the environment during its lifetime largely remains a mystery. Stable carbon and oxygen isotopes in otoliths (fish hearing organs) provide an alternative “natural tag” that continuously logs the water temperature, food web use, and geochemistry of the water in which an eel is living. In this talk, I will describe how I used this tool to follow a population of American eels that were experimentally stocked in the upper St. Lawrence River between 2006 and 2010. Where did these eels disperse to after stocking? Did they behave like wild eels? Is climate change a factor in the species decline? Where are they now? 

Courtney recently completed her PhD at Queen’s University and joined the River Institute as a Research Scientist. She has spent over a decade studying the ecology of the American Eel in both the laboratory and the St Lawrence River using stable isotopes and eel otoliths to understand the interactions between eels and their environment.

Her career in fisheries began while handling nets and sampling fish communities in Lake Ontario as a student fisheries technician for the OMNRF. She then completed a B.Sc. (Honours) in Biology at Queen’s University and, before pursuing graduate school, worked as a Research Biologist on two Species at Risk projects that examined the abundance of Lake Sturgeon and American Eels in the upper St. Lawrence River.

Conserving little brown bats in Ontario

Brian Hickey

Brian received both his M.Sc and Ph.D. from York University where he specialized in the foraging and thermoregulatory behaviour of red and hoary bats in southern Ontario. His bat research has brought him to Zimbabwe, the Yucatan peninsula of Mexico and Ontario, Canada. While Brian is well known for his bat research, he has studied a wide range of taxa including birds, fish, reptiles, and invertebrates.

The unifying theme throughout his research has been an interest in understanding the role that environmental variation and individual behavioural variation has on the structure of animal populations and communities. Most recently, Brian has been investigating contaminant burdens (particularly mercury) in bats as well as monitoring the status of bat declines due to white-nose syndrome. In an effort to support bat populations, Brian has built and deployed over 170 artificial roosts across Ontario. As part of this effort, his team is currently documenting the recovery and growth of several colonies of endangered little brown bats.

In addition to his role as a research scientist, Brian oversees the River Institute’s education and outreach programs, which in 2019 received a national award from the Natural Sciences and Engineering Research Council of Canada (NSERC), for their excellence.

Bats in North America face numerous threats including loss of habitat (especially roosts), reduced prey populations due to excessive use of insecticides, exposure to contaminants including mercury, mortality caused by wind turbines, and the devastating effects of the introduced fungus that causes white-nose syndrome.

This fungus, which was first identified in New York state in 2006, is now found throughout Canada (and most of the US) and has resulted in population declines in bat hibernacula of more than 99%.  These massive declines might represent the largest decline in a mammalian population since biologists began tracking these types of events and has prompted some experts to predict the extinction of some species of North American bats.

Between May and August 2021, Brian and his team have surveyed potential maternity roosts of endangered little brown bats (Myotis lucifugus), one of the species most severely affected by white-nose syndrome. The roosts they surveyed included bat houses built and deployed by Brian, buildings or bat houses that were historically occupied by bats, and buildings owned by people who reported that they had bats living in their attics.

Brian identified 20 M. lucifugus roosts, including 17 bat houses and 3 buildings. Emergence counts were conducted at 11 of the 20 roosts with coloniy sizes ranging from 1 – 200 bats (mean 96). These results suggest bat populations in eastern Ontario may have developed resistance to the fungus and may be slowly recovering from the declines caused by white-nose syndrome.

A St. Lawrence River Odyssey on board the Lampsilis research vessel

Francois Guillemette

Riverine population identify with and use the St. Lawrence for food, transport, recreation and culture, but in turn significantly modify the sustainability of these ecological services. For example, the acceleration of human activities in recent decades has depleted some economically important fish stocks, destroyed wetland habitats, degraded water quality and accelerated invasions of unwanted species. However, at the local and regional levels, these impacts vary in their nature and intensity due to the complex hydrology of the St. Lawrence and the presence of different sources of pollution (urban and agricultural) along the river. Come aboard the Lampsilis research vessel to discover the fragile nature of the river and the most recent research results concerning its health.

François Guillemette is a Professor at the Université du Québec à Trois-Rivières, Trois-Rivières, Quebec and currently holds the UQTR Research Chair on the Ecology of the St. Lawrence. His research interests revolve around the fields of aquatic carbon biogeochemistry and microbial ecology. Of particular interest is the export, transformation and fate of organic matter from land to rivers, and the understanding of the metabolic response of microbial communities to changes in the supply, source and composition of organic material. His work also focuses on how urban and agricultural pollution affect the composition of microbial communities and the role they play in the functioning of river ecosystems and the services they provide to the society. Aside from his research program, he also has great interests in public education for the preservation, valuation and restoration of aquatic ecosystems.

Water, Fish, & Community

Barry N Madison, Ph.D

I take an integrative molecule-to-population level approach to my research. I draw on my broad research experience employing techniques from physiology, endocrinology, and toxicology to study animal responses to environment and climate change. In this presentation, I will provide some perspective on my background and approach to research, as well as the story of why Water, Fish, & Community represents a new age of integration in my scientific journey. Recent events have caused many scientists to reflect on what is important to us, and my hope is to demonstrate how COVID has made many of us rethink our approach to research. Instead of a detailed presentation of data, I hope to share my experiences and highlight the importance of flexibility in scientific research. I will offer some examples of this in practice using my own experience with recent collaborations with the River Institute. I will close with what I see as the opportunities, and their challenges for this way forward ahead. 

Originally from Kenora, ON, Barry pursued his passion for aquatic biology at Queen’s University and completed his PhD at the University of Guelph, where his research focused on the endocrine mechanisms of stress and growth in salmonids. A post-doc placement at the Royal Military College of Canada furthered his expertise in ecotoxicology in his work studying the effects of petrochemicals and novel watershed contaminants. As a Research Associate and Adjunct Professor at Queen’s University, he expanded his research into oil sands wastewater decontamination processes; explored modern methods for monitoring contaminants and indicators of ecosystem health; and studied novel bioremediation methods for harmful algal blooms. 

Barry has recently acted as a science contributor and advisor to the River Institute’s Great River Rapport, and his recent work with the Great Lakes Institute of Environmental Research (University of Windsor), Queen’s University, and the River Institute focus on Water, Fish, & Community.

Permaculture: An Introduction to Going Beyond Sustainability

Audrey Constance Wagner

MSc. candidate in Environmental Change and Management | University of Oxford BSc. Environment and Food Production | McGill University

In this Introduction to Permaculture, speaker Audrey Wagner lays out the foundation of permaculture theory and showcases some specific techniques and tools typically used in permaculture, before illustrating some examples from around the world. Permaculture (from permanent-culture or permanent-agriculture) is a system of design based on the observation of nature to create human societies which are beyond sustainable, abundant and regenerative. Emerging from the disciplines of ecology, systems thinking and traditional indigenous knowledge, permaculture guides us to work with nature to meet human needs while regenerating the environment at the same time. 

Audrey Wagner is an expert in the intersections between sustainability and food systems. Having conducted research on agroecological farms across the world, from Belize and India to Panama and Portugal, she is particularly well-versed in Permaculture. From Montreal, Canada, she holds a BSc. in Environment and Food Production, with a minor in International Agriculture, from McGill University. She is the co-founder of four organizations including the Macdonald Permaculture Showcase Garden and McGill Permaculture Club, and has worked as Sustainability Coordinator for McGill’s Food and Dining Services, researcher for the International Institute for Sustainable Development in Canada and for the United Nations World Food Program in Havana, Cuba. Currently studying an MSc. in Environmental Change and Management at the University of Oxford in the UK,

her current research focuses on payments for ecosystems services and indigenous sovereignty in the Peruvian Amazon. Audrey hopes to go on to work on agricultural nature-based solutions to climate change and biodiversity loss, while empowering farmers to strengthen their resilience and livelihoods, particularly in Latin America.

Exotic invasion of the Upper St. Lawrence River: Moderating Factors and Emerging Questions

Dr. Alison Derry
Associate Professor Université du Québec à Montréal

Exotic invasion is globally recognized as one of the most serious persisting threats to aquatic biodiversity and ecosystem function. Invasive species are difficult if not impossible to eradicate from natural ecosystems, and so it becomes it is important to understand factors that could moderate their ecological impacts once they have become irrevocably integrated in food webs. I will revisit the ecological impacts of round goby fish invasion in the Upper St. Lawrence River (Canada) on resident macroinvertebrate and fish communities, by taking into consideration the effects of time since initial invasion 20 years ago. I will also address how different refuge types constrain round goby invasion impacts on native biodiversity at the whole ecosystem-scale of the Upper St. Lawrence River. I will finish by discussing forthcoming research questions on how round goby invasion may impact contaminants and ecosystem services for humans.

Alison Derry received a BSc in zoology/environmental biology (University of Guelph), a MSc in limnology (University of Alberta), and a PhD in ecology and evolution (Queen’s University). She is presently an associate professor in the department of biological sciences at the Université du Québec à Montréal (UQAM). Her research program applies ecological and evolutionary theory to aquatic field ecosystems to address adaptive responses to environmental disturbance from populations to communities to ecosystems.

Michael Twiss is Yankee who grew up in northern Ontario, and arrived at Clarkson in 2002, following a brief tenure at Ryerson University (Toronto). Twiss’s expertise is in limnology of the Great Lakes-St. Lawrence River system.

Smart Bioplastics Products

Dr. Prashant Agrawal
Chief Scientific Officer Plantee Bioplastics

Plastics have varied application and have become an essential part of our daily lives. The use of the plastics has increased twenty-fold in the past half-century and is expected to double again in the next 20 years. As a global estimate, around 330 million tonnes of the plastics are produced per annum. The production, use and disposal of the plastics emerged as a persistent and potential environmental nuisance. The improper disposal of the plastics ends up in our environment, resulting in the deaths of millions of animals annually and also the reduction in fertility status of the soil. The bioplastics products are manufactured to be biodegradable with similar functionality to that of conventional plastics, which has the potential to reduce the dependence on petrochemicals based plastics and related environmental problems. The talk will focus on Plantee’s innovative technologies to make bioplastics more accessible. 

Prashant holds a PhD and MSc in analytical and material sciences from Queen’s University, Canada. He did his undergraduate (Dual BS-MS) from Indian Institute of Science Education and Research, India in Chemistry. His expertise lies in Scientific chemical formulation, experimental design, chemical analysis, engineering analysis, and product design and development. Prashant’s expertise in surface modification and analytical chemistry provides a deeper understanding of the science behind the bioplastic development process. 

Otters and Contaminants from the Oil Sands

Dr. Philippe Thomas
Wildlife Biologist, ECCC – National Wildlife Research Centre

River otters are sentinel species of aquatic ecosystem health. In areas like the Athabasca oil sands, environmental loadings of polycyclic aromatic compounds (PACs) and trace elements are increasing in areas of oil and gas extraction. Some of these chemicals have potential to affect reproductive health in river otters. Dr. Thomas’ research is investigating the toxicological impacts of PACs and trace metals on otters and developing unique methods to assess reproductive health. 

Dr Philippe Thomas is a wildlife toxicologist at ECCC with significant expertise in the biology of semi-aquatic mammals and migratory birds, field studies, impacts of persistent organic pollutants (POPs), heavy metal exposures and complex mixture assessments. He has more than 10 years of experience working with local stakeholders and Indigenous communities in and around the oil sands and the Canadian Arctic. Additionally, he is the project lead for the Arctic Seabird Monitoring Program, the federal/provincial oil sands monitoring program: hunter/trapper-harvested wildlife and toxicology project, and a community-led waterbird egg collection program part of the St Lawrence Action Plan.

Philippe works extensively with Indigenous communities impacted by resource development projects. Over the last 5 years, his work has focused on establishing chemical profiles of oil and gas contaminants on the feathers and in the organs of migratory game birds and mammals. 

Why do Landowners Restore Wetlands, and how does the Community Benefit?

Tom Langen
Interim Dean of Arts & Sciences at Clarkson University

The greatest opportunities for conservation of biodiversity and enhancement of ecological services are found on private property. In the St. Lawrence Valley and eastern Lake Ontario region of New York State, over 250 landowners have partnered with governmental agencies to restore and enhance wetlands on their property. What are the objectives of wetland restoration programs for the governmental agencies? Why do landowners chose to restore wetlands? Are wetland restorations similar to natural wetlands in terms of hydrology and water quality? Do they provide quality habitat for wetland-associated plants and animals? Tom Langen and his team’s research aimed at answering these questions, and providing best practices for public-private partnership wetland conservation programs.

Dr. Tom A. Langen is the Interim Dean of Arts & Sciences at Clarkson University. Dr. Langen conducts research on the environmental impact of roads, and on the effectiveness of public-private partnerships for wetland restoration. He leads professional development workshops in Latin America and North America on the environmental impact of roads and other infrastructure, and on wetland restoration. Prof. Langen teaches courses related to ecology, conservation, and animal behavior, and has published pedagogy research on innovative college teaching activities. He is also involved in local river conservation, public access, and village revitalization as a board member of Grasse River Heritage and the St. Lawrence Land Trust.

Reaserch Scientist at River Institute & MSc Candidate, University of Ottawa

Come hear Brian and Bailey discuss their research about the biological effects of mercury in bats!

Dr. Brian Hickey received his PhD in biology for work on temperature regulation in Hoary bats and he has studied bats in Canada, Mexico, and southern Africa. At the River Institute, his research theme has been how habitat changes impact animal populations. His recent work has focused on recovery efforts for Little Brown Bat populations that have been decimated by white-nose syndrome.

Bailey Bedard is from Ingleside, Ontario and is a MSc candidate at the University of Ottawa where she studies the molecular effects of mercury contamination on bats.

The Aquatic Rollercoaster: How the River’s Ups and Downs Impact Biodiversity

Matt Windle
Research Scientist at River Institute

River water level fluctuations are a natural phenomenon that help shape aquatic communities. However, the St Lawrence River (SLR) water levels have been managed for the past 60 years. Join River Institute Research Scientist, Matt Windle, for a talk on what the SLR used to be like and how aquatic life have adapted to the changes over the years. Matt has studied Hoople Bay to see how the biodiversity compares to other sections of the river that do not experience the same severe water level fluctuations and to track seasonal biodiversity changes.

Effects of Legacy Contaminants on the Great Lakes Ecosystem: A Proteomic Approach

Emmalyn Dupree
Chemistry PhD Candidate at Clarkson University

Emmalyn Dupree is a Chemistry PhD candidate at Clarkson University. Her research includes identifying the effects of legacy chemical contaminants in the Great Lakes on the human proteome. Proteome are all the proteins in the human body and are crucial to normal human functioning and factors in disease. Legacy chemicals come from the manufacturing and use of such things as pesticides, coolants, flame retardant, fertilizers, insulation, etc. Emmalyn’s research is part of a project for the Environmental Protection Agency.
