Research

Macroecology and Global Change

Macroecology is the study of ecological processes at very broad spatial scales: by leveraging pre-existing datasets that cover massive spatial and temporal extents, we are able to answer pressing questions in global change and conservation. Broadly, we ask how climate and landcover change impact species’ ranges and diversity. This can include questions about effects of pesticides, short and long-term climate trends, and habitat loss and connectivity, among others. While this work often focuses on well-studied insects like bees, butterflies, and dragonflies, we also exploring patterns in birds and mammals.

Landscape and Metacommunity Ecology

While this type of research is done at a much smaller scale than our macroecology work, designing and conducting our own field surveys allows us to ask questions about the impacts of global change that can’t be answered with existing data. We have tended to pursue topics like landscape change, habitat connectivity, and plant availability for pollinators, but many other lines of inquiry are possible. Recently we have become particularly interested in microclimates, and how small-scale climate extremes can have important impacts on species and communities. Observing our study organisms in the field is always encouraged, and can give us a new perspective on our macroecological research.

Publications

Our research group has >110 publications, with several additional articles in process, and 3 books on EDI and education. "In preparation" works aren’t listed. These papers have accumulated around 16,800 citations and Kerr has an H-index of 55.

We try to make every contribution count in terms of scientific and societal benefit (i.e. NOT "minimum publishable units"). We work with media frequently and have contributed to policies and legislation provincially and nationally in Canada. Examples of impact include contributions to the Ontario Endangered Species Act, conservation commitments in the northern boreal regions of Canada, protected area planning at the federal level, specific policies and practices around equity, diversity, and inclusion, and issues around the recovery of science integrity in Canada. 

Scientific publication is in transition. We have often published our work using the "gold" open access standard, but associated costs have grown unsustainably and can become unsupportable on public research funds. We will shift, sometimes, to the "green" standard. While we continue to use social media, we are shifting toward Mastodon and decisively away from Twitter for ethical reasons. Mainstream media covers our work intensively and we are often asked to comment on developments in the news (e.g. COP15).

Biography

I am an elected Fellow of the American Association for the Advancement of Science (AAAS), the Royal Society of Biology, and an invited member of Sigma Xi Scientific Honours society. I held the University Research Chair in Macroecology and Conservation from 2013 to 2023. I am a past President of the Canadian Society for Ecology and Evolution, where I led work on EDI and on policy engagement. I am an alum of the Global Young Academy and have had research successes that are important to me, including Young Researcher of the Year, Early Researcher Award from Ontario, Science Ambassador for Canada (from Partners in Research), the Excellence in Media Relations prize for Research, and the University of Ottawa Leadership Award for Teaching for work on inclusive and online teaching practices during the pandemic. I was recently recognized as the Faculty of Science Researcher of the Year.

I did my undergrad at U of O in Biology and my honours project with David Currie and my PhD at York with Laurence Packer. I went on to a postdoc in Oxford with Bob May and Dick Southwood. I can't do either of these legendary scientists justice here. I ended up back in Ottawa as a research scientist in remote sensing with the stellar Josef Cihlar, and then full circle to Biology at University of Ottawa. I returned to Oxford for sabbatical as an elected Senior Research Fellow in Mansfield College and the Institute for Environment.

I try to give back more than I use. I am strongly engaged in public science and at the science-policy interface. Activities I’ve helped lead include improving endangered species legislation in Canada and Ontario, the development of federal policies around equity, diversity, and inclusion in research, boreal conservation, malaria challenges in East Africa and as a voice opposing the Orwellian perversion of facts and evidence at the federal level in Canada during a previous government. I worked with then Minister of Science, the Hon. Dr. Kirsty Duncan, to champion the proposal and development of Canada’s Chief Science Advisor, serve as an executive of NSERC Council as Chair of Discovery Research. I serve on NSERC Council Executive, a Governor-In-Council appointment (approved by Federal Cabinet and the Governor General).

Lab Values

Participation and Support

Participating in the lab as much as possible, and supporting other lab members, improves everyone’s experience. Engagement with other lab members is vital for learning and growth as a scientist, and lab members should spend time in the lab whenever possible. This also facilitates a feeling of community in the lab, and fosters connections between lab members. Everyone is expected to attend lab meetings during the year, except when field work or other research activities cause conflicts. Lab members are also expected to present talks or posters at scientific conferences, and attend departmental seminars when they intersect with our research interests. Lab members are encouraged to participate in science communication activities (i.e. Let’s Talk Science, BioMatters magazine), the uOttawa Biology Graduate Student Association (BGSA), and other science or department related organizations and events.

Colleagues can be great sounding boards for research ideas, lab protocols, methods for analysis, etc. Students and post-docs often review each other’s research proposals and scholarship applications, and lab members present to the lab for feedback before conferences and research committee meetings. Lab members are encouraged to introduce new members to Ottawa, include them in social events, and generally make everyone feel welcome. All lab members should attend lab MSc and PhD thesis defences, and should try to attend lab social events when possible (get excited for the yearly Mas-Kerr-Chef cooking competition!).

Mental Health

By fostering a respectful and collaborative environment, and participating and supporting each other, we hope to build a foundation for good mental health in the lab.

In addition to this, we encourage students to respect their own limits, and create a healthy work-life balance for their time in the lab and beyond. This means working a reasonable number of hours and giving ourselves time off: depending on how you like to work this might be working 9-5 and taking weekends off, or working a more flexible schedule. In your down time we encourage you to relax and do things you enjoy - check out the Biology Graduate Student Association events or explore Ottawa! Vacations are also important, and we have a flexible approach to ensure everyone takes the time that they need.

Another important strategy is to celebrate the small wins. A research project can take a year or more from conception to publication, so setting smaller goals (finishing data collection, finishing analysis, presenting at a conference, first draft done!) can help keep you aware of all the progress you’re making.

Finally, if you are ever struggling with burnout, feeling overwhelmed, or experiencing other mental-health issues, remember that other lab members have likely been through the same thing, and you can always talk to Jeremy and your colleagues.

Media

Précis on media engagement:
The Kerr Lab does a lot of media work around biodiversity conservation, climate change, scientific integrity, and the development of science policy. We have been quoted in most major media outlets for both broadcast and print, as well as in the science press (e.g. Science and Nature) and popular science press (e.g. National Geographic, Scientific American, Popular Science, New Scientist, etc.).

Working with the media means keeping a different set of rules in mind when having a conversation. You’re always on the record unless it is explicitly agreed otherwise. It can be embarrassing if you get taken quoted out of context. Everyone makes mistakes when engaging in outreach. The trick is to avoid really big ones (e.g. saying something not supported by evidence or false claims about expertise). Never, ever claim a personal view is the same as a scientific view. This can (and should) kill credibility.

Care about what you’re saying and say it concisely, accurately, and memorably. Think about who is hearing you speak, not about how you most want to say something. 

We do a lot of outreach beyond traditional scientific venues. This is particularly important these days as a means of countering disinformation about basic scientific evidence for conservation and global change. We need to present the evidence as it actually exists to enable more informed decision-making. 

Public decision-making isn’t going to be made better if scientists don’t help the general public and political establishment understand the nature of discovery and the evidence that exists for some of the most pressing environmental challenges.

Biologists wait to see whether warm-weather insects survived brutal winter
Publication: Ottawa Citizen
Date: Tuesday April 1st, 2014
The giant swallowtail is a gorgeous butterfly from Canada’s extreme south. Biologists won’t know for certain until warm weather begins, but they’re watching to see whether the butterfly and other warm-weather insects will survive the coldest winter in 20 years. Jeremy Kerr, Department of Biology, reveals that this year will be especially insightful for understanding how climate change is going to alter the geographic range of species.

Monarch butterfly count in Mexico reveals steep decline

Media engagement around “Climate change impacts on bumblebees converge across continents”, published in Science (2015) and “Climate change contributes to widespread declines among bumble bees across continents”, published in Science (2020).

Media coverage for these papers was global. The first of these papers, edited by Dr. Sacha Vignieri at Science, was the subject of a press event that the American Association for the Advancement of Science organized. The AAAS and their chief press officer, Natasha Pinol, decided this work seemed significant (we were just happy to have addressed the reviewers’ comments) and we worked with them to assemble multimedia materials. Natasha’s efforts deserve great credit and so do those of the uOttawa media crew. A partial list of media that excludes much non-English coverage and most radio broadcasts. We will expand the list when we have a more complete picture of how this work was covered.

We were misquoted a few times and some media outlets suggested that climate change is a silver bullet killer for bumblebees, and that nothing else matters. That just isn’t right at all, and we never said or hinted at this. We did find a distinct effect of climate change that was not due to neonicotinoids or habitat changes, but we already know those factors kill bees. Honestly, how anyone can find it surprising that insecticides kill insects is beyond me (neonicotinoids are insecticides). Nevertheless, neonics and habitat losses are not a silver bullet explanation any more than climate change is. We are hitting bees with everything we’ve got. It’s like claiming that because smoking causes lung cancer, it is impossible to suffer health problems for any other reasons. 

Oh, and this work led to many wingnut emails also. We have been informed, in no uncertain terms, that we are secret agents for the pesticide industry, that cell towers cause global pollinator declines, and that Satan is responsible. Oh yes, and that tomatoes don’t need pollinators. Ever. The climate change deniers trolled out over this too, but didn’t say anything unusual or factual. We receive many nice messages also. 

It was also pretty cool that Leonardo Di Caprio and Margaret Atwood sent out messages on social media about our 2020 publication in Science.
