Extreme Weather Impacts Wildlife Too

Extreme Weather Impacts Wildlife Too

Extreme weather caused by climate change has had a devastating impact on the human residents of B.C. The heat dome in June 2021 led to over 600 deaths in the province, while in September 2020, wildfires in and around B.C. led to Vancouver having some of the worst air quality in the world. The impact on wildlife and biodiversity, however, is not well understood and since the timing and the intensity of extreme weather events are unpredictable, it is difficult to research. This knowledge gap led the researchers of the Long-term Biodiversity Monitoring Program at the UBC Farm to use their data to investigate what impact extreme smoke and heat had on the wildlife that call the UBC Farm home.

The project has used automated cameras and audio recorders across the UBC Farm since 2019, gathering photos and sounds on birds, bats and mammals. The researchers assessed the data from the periods of the heat dome and wildfire smoke, and found that some, but not all, species decreased their activity. For birds and coyotes in particular, their behaviour increased slightly during the period of intense wildfire smoke.

“We often imagine that extreme weather events will have dramatic effects on wildlife,” says Dr. Matthew Mitchell, Research Associate in the Faculty of Land and Food Systems. “While coyotes and bats seem to decrease their activity with wildfire smoke, squirrels and birds can actually be more active. Some of this might be because of predator-prey interactions, where squirrels notice coyotes are less active so they in turn become more active. Or it might be because species like birds need to broadcast their presence and territories more when it is smoky.”

The researchers do not yet know why the animals behave as they do, but intend to find out more as they gather more data over the long-term.

Student Learning

Funded by an NSERC Discovery Grant and UBC Campus as a Living Laboratory, the project team was also supported by the UBC Farm Undergraduate Research Competition, which funded two students to get involved in the research.

“I was amazed by how many different forms of data we were collecting, ranging from physical surveys to audio recordings to motion-sensor trail camera photos,” says Julia Taylor, one of the undergraduate research assistants who worked on the project in summer 2022, adding that this experience has influenced her future career goals after she graduates in a few months.

Another student working on the project, Brooke Carlisle, found working with new and emerging data rewarding, even though it pointed to a lack of data on heat waves and terrestrial ecosystems.

“The 2021 heat dome has been well documented for its impacts on marine invertebrates, and previous heat waves have been linked to mortality of marine birds,” says Carlisle. “However, we found fewer studies on how animal communities on land react to extreme heat events. I’m glad that we are helping to strengthen this area of scientific literature that needs further research.”

Agriculture and Biodiversity

Dr. Matthew Mitchell

Wildlife and farmlands have important and beneficial interactions, says Dr. Mitchell, adding that a large proportion of the threatened species in Canada live in agricultural areas
since agriculture has driven the loss of their habitat.

“Wildlife species don’t just live in pristine habitats untouched by people. They are also integral parts of agricultural systems and can provide really important benefits to people, including farmers,” says Dr. Mitchell. “This includes pollination, pest control, and opportunities to appreciate and learn about nature. Understanding how to manage agricultural landscapes so that they also support biodiversity and wildlife species is one of the best ways to conserve nature and has the additional benefit of also increasing agricultural sustainability.”

Carlisle adds that this research may also point to the importance of having cooler, shaded areas within working landscapes to provide refuge for animals experiencing heat stress during these heat waves.

Long-term Monitoring

The project is ongoing, and the researchers are keeping an eye out both for long-term changes in the species they monitor, as well as any effects from more sudden extreme weather events. They will also be exploring ways to expand automated monitoring beyond the UBC Farm to investigate trends in biodiversity across Vancouver and the region to better understand more widespread impacts of climate change and extreme weather events.

For Dr. Mitchell, the project hits close to home, literally. As well as conducting research at the UBC Farm, he also lives close by and his kids spend a lot of time at the farm.

“Climate change is something that I think about basically every day and something that, as a parent, causes me daily stress and worry,” says Dr. Mitchell. “This project gives me an opportunity to contribute a little bit towards understanding, and potentially mitigating, the effects of climate change at a local scale and help conserve biodiversity in my neighbourhood.”

More Hybrid Learning on the Horizon

More Hybrid Learning on the Horizon

Through UBC’s Teaching and Learning Enhancement Fund, these faculty members are taking time to update or develop new courses, and create richer online content for the future hybrid learning environment. As part of the process, they have invited students to join their project teams to share their insights.

Dr. Lindsay Cuff, Assistant Professor of Teaching in LFS and Forestry, is leading a group of UBC instructors and students in updating scholarly writing curriculum adapted to a flexible hybrid teaching environment. The transformed curriculum, including new online learning modules and in-class extension activities, will impact first-year students and will thread through their undergraduate degrees into second-, third-, and fourth-year, fostering students’ growth, persistence, and identity as writers in scholarly communities.

Last year, Dr. Cuff launched a free, online textbook on scholarly writing called Writing Place. She wants to empower students to contribute to scholarly conversations and have them consider how their contributions can be shared beyond the university.

Dr. Ronaldo Cerri, Associate Professor and Director of UBC’s Dairy Education and Research Centre, is updating two animal health and physiology courses (APBI 312 and APBI 410) to create more hybrid learning opportunities aimed at improving student engagement, understanding of concepts and knowledge retention. By providing students with a hybrid model of teaching, Dr. Cerri
also hopes to reach a wider range of students with new learning opportunities. He will be supported by graduate students on this project.

The Food and Resource Economics (FRE) group, led by Professor Dr. Sumeet Gulati, will develop new courses for students in the undergraduate and graduate programs. The motivation is twofold: to fill in knowledge gaps in this relatively new program; and, to create in-class and online course materials. The new courses will include two undergraduate courses focussing on data analysis, and two graduate courses in microeconomics and econometrics. Graduate students will support FRE faculty members on the project team.

Developing Wildlife Welfare Policy Throughout the Province

Developing Wildlife Welfare Policy Throughout the Province

Erin A. Ryan
Bsc/MSc Applied Animal Biology

May 11, 2023 – Alumna Erin A. Ryan’s (BSc/MSc Applied Animal Biology) career sits at the intersection of science, community, and social good. From developing wildlife welfare policy to furthering Equity, Diversity, and Reconciliation in her field, Ryan’s work is multi-faceted and wide-reaching.

Ryan’s family history with the Faculty spans generations. She first learned of the Applied Biology program in 2008, when she attended a ceremony where her grandfather received an LFS Centenary Award for his outstanding achievements as an alumni. Celebrated LFS alumnus Len Marchand (BSc Agriculture 1958) had a groundbreaking career in politics as the first person of Indigenous status to serve as a Member of Parliament, but Ryan thinks of her grandfather as a scientist at heart.

“He was so proud I was going to UBC,” Ryan said. “And especially because I would be an Aggie like him.”

In the Applied Biology program, Ryan discovered her professional calling in the science of animal welfare. She currently works at the B.C. Society for the Prevention of Cruelty to Animals (BC SPCA) as a Specialist in Wild Animal Welfare.

Ryan’s initial focus was on urban wildlife, but she now works on provincial wildlife welfare initiatives that focus on public communication and advocacy. Ryan translates research and best practices into clear and actionable statements for implementation.

From her experience working for the BC SPCA, Ryan found a gap in the published research. There was a good body of research in humane control for most wildlife, but for mice and rats, research was mostly focussed on selecting the least harmful option of removal. Ryan wanted to find practices that actively considered humaneness instead and decided to pursue a master’s degree, which she completed in 2021.

Ryan describes her return to LFS as a homecoming, and her research on more humane pest control has actively shifted provincial policy. While defending her thesis, Ryan and fellow
alumna Dr. Sara Dubois (PhD Applied Animal Biology 2014) were consulted by the provincial government to help inform new regulations on rodenticides and pest control.

The province made the first set of temporary restrictions in July 2021, banning the non-essential use of Second-Generation Anticoagulant Rodenticides (SGARs), which are the most potent rodenticides and cause secondary poisoning for hawks, coyotes, and other predators. In January this year, the restrictions were made permanent. Along with restricting the sale of SGARs, these changes led to more proactive solutions that targeted the root cause of rodent infestations.

Ryan’s goal as a science communicator is to create policy that reflects all aspects of welfare, including those affected by systemic and societal biases. In 2020, Ryan joined the new BC SPCA Equity, Diversity, and Reconciliation working group, formed as a response to increased public attention on reconciliation.

Members vary by location throughout the province, to ensure that welfare concerns and communications are not limited to urban centres or any particular region. In the three years since
its inception, Ryan has worked with the group to publish their Foundational Principles for Equity, Diversity, and Reconciliation. The increased public attention has given Ryan hope.

“People are listening now,” Ryan said. “They won’t stand for lip service anymore, and organizations are trying to make meaningful change. This work is just beginning.”

Improving Clinical Practice in Pediatrics

Improving Clinical Practice in Pediatrics: The Importance of Patient-centred Care

Brock Williams
PhD candidate in Human Nutrition

Brock Williams, a PhD candidate in Human Nutrition and a Registered Dietitian, has worked in pediatric nutrition for almost a decade. He says that research approaches have changed significantly over the years.

“In the research field, we’re used to disseminating information through publications and journals and going to conferences,” explains Williams. “We’re much more aware now that we have to involve patient partners in planning and designing research so that we’re asking the important questions that patients want to have answered.”

Williams is currently finishing up his PhD where he is studying folic acid supplementation in children with sickle cell disease, a genetic disorder that causes a rapid turnover of red blood cells. Folic acid, the synthetic form of folate, helps to produce red blood cells but since it is now in our food systems through mandatory fortification, researchers have questioned whether children still need to take supplements. Additionally, from the patient perspective, taking a daily folate supplement in addition to multiple other medications
can be burdensome for children.

A major component of Williams’s project was leading a clinical trial looking at whether current clinical practice needs to be re-evaluated.

“It’s a very involved process but I think the exciting thing about doing clinical trials is that the outcomes can really influence clinical practice,” says Williams. “I decided to go into a PhD because I wanted to conduct research that generates more evidence for clinical practice in pediatrics.”

Williams explains that the current practice for folic acid supplementation in sickle cell disease is largely based on results from a study that was done in 1983.

“A lot of the evidence that we have for this widespread clinical practice is old and very scarce so for this project in particular, there was a big need to have more high-quality evidence to answer that question.”

For his post-doctoral research, Williams will be joining the Division of Allergy at BC Children’s Hospital, where he will focus on identifying the challenges and barriers that caregivers experience in introducing and regularly feeding infants commonly allergenic foods, such as peanuts, tree nuts, eggs, sesame, shellfish, fish, and wheat.

In 2019, the Canadian Paediatric Society introduced new recommendations on preventing food allergies in babies: common allergenic foods can be introduced into the diet of children who are at higher risk of developing a food allergy around six months, but not before four months of life. This was a significant change from advice in the early 2000s, which was to delay
the introduction of common allergens to children until later in life – up to two years old.

This shift resulted from large, well-designed clinical trials that demonstrated the benefit of earlier introduction of allergenic foods, particularly peanut and egg, for the primary prevention of food allergy.

Williams explains that major issues for implementing the guidelines are often centred around convenience: lifestyle inconvenience and challenges with food preparation. Other issues include infant refusal of foods and parental perceptions around reactions to foods, where a child might have a skin issue or digestive issue and parents might perceive that as an allergic reaction.

With the research team at BC Children’s Hospital, Williams will be working closely with families to address these issues, develop unique strategies to overcome them, and promote frequent intake to maintain tolerance.

Communicating this type of research to the general public is also a priority: “We can’t just publish in journals and go to conferences. We have to disseminate the information in an accessible way so that individuals who are affected by certain conditions can see what’s happening in research and what the advances are too.”

Some of the communication initiatives that Williams and clinician-researchers at BC Children’s Hospital are planning include social media outreach and webinars, in partnership with organizations like Food Allergy Canada.

“At BC Children’s, parents of children with food allergies have expressed to us that they wished this information was accessible to them when they started introducing solid foods to their infants, and that accurate, evidence-based guidance on social media would have been so helpful.”

Dean’s Message

May 10, 2023

Dean’s Message

This issue showcases some remarkable up-and-coming researchers. PhD candidate Brock Williams, in our Human Nutrition program, is doing work on two fronts to help families manage health issues. His PhD research is updating studies on how much folic acid supplementation is needed for children with sickle cell disease, including whether clinical practices need to be re-evaluated based on our changing food system. In his upcoming post-doctoral research, he’ll be working with caregivers to safely introduce potential allergens to infants.

Wilson Mendes is another PhD candidate, an interdisciplinary scholar who aims to expand Indigenous land-based education programs in urban spaces. This is based on his recent community research and experience at the three Indigenous Gardens at UBC Farm, where he saw the importance that culturally relevant and safe spaces can have in reclaiming self-determination and in cultural revitalization.

Varinia Cabrera is an exchange student from Uruguay who chose to study at our Animal Welfare Program to build a bridge between research in her home country and here at UBC. She is a master’s engineering student who builds technology to improve outcomes for animals in agriculture. She’s gaining knowledge about animal welfare practices and technology used in Canada, while providing her expertise to our researchers.

And lastly, changing weather patterns is top of mind for many people. What impact can extreme weather have on wildlife and biodiversity? Dr. Matthew Mitchell has collected data from the 2020 wildfire season and 2021 heat dome in B.C. to begin tracking the behaviour of bats, birds and mammals at UBC Farm. His study helps take a long-term look at how animals behave in extreme weather conditions.

Classroom learning: Insights from teaching award recipient

Tony Yang, a master’s student in Human Nutrition, was awarded the Faculty’s 2023 Killam Graduate Teaching Assistant Award to recognize his exceptional work enhancing student learning.

Throughout his master’s degree, Yang supported multiple LFS undergraduate courses, including FNH 160 (Integrated Physiology for Human Nutrition I), FNH 350 (Fundamentals of Nutrition), and FNH 477 (Nutrition and Disease Prevention).

By creating a welcoming and inclusive classroom environment, Yang helped students feel free to collaborate and learn. He encouraged students to explore their own interests, and tried to cater to each student’s individual needs and learning styles.

“When students were having difficulty grasping a concept, I treated them the way I would want to be treated if I were in their position,” Yang says. He tried to avoid just directly providing the correct answer to students if they got something wrong.

“The most rewarding part was during mid-term viewing sessions. When I saw a student struggling to grasp a concept, we would walk through their logic, and from there we’d identify where the logic didn’t connect. I tried not to give answers right away.

It’s important that students reach an answer using their own understanding. They’ll be able to recall it later better because they found it on their own terms.”

Yang finished his undergraduate studies in 2020 (BSc FNH) and was heavily involved in the LFS community during those years. He speaks fondly of his time at Agora Café where he made several friends with the other volunteers. He said it was a good learning experience managing the café and working as the catering manager who oversaw external orders.

It was in a third-year class that he discovered Dr. Barbara Stefanska’s research on molecular nutrition and cancer, specifically nutritional epigenomics. He was excited by Dr. Stefanska’s research and asked to volunteer in her lab, then decided to pursue a master’s degree to study human nutrition under her supervision. He recently completed his master’s thesis investigating pterostilbene, a compound found abundantly in blueberries, and its anti-cancer effects in liver cancer cells.

Yang also learned some things about himself during his time as a teaching assistant with his biggest takeaway being the realization that he truly enjoyed teaching – maybe even a little more than research: “I get more fulfillment interacting with students than looking at my machines and test tubes all day!”

This leads to a perfect next step for Yang – following graduation, he will be joining Capilano University as an Instructor for an Introductory Nutrition course.

Yang’s advice to students:
“Follow the learning objectives and treat them as their own exam questions. Also, don’t cram in your studies: study consistently throughout the term in shorter study blocks, frequently test your knowledge, and most importantly – remember to take breaks!“

Student Spotlight: Vivian Li

Vivian Li

What has been the best part of your university experience and your student life in LFS?

The people I’ve met, and all the moments and experiences I’ve shared with them. It’s really the culmination of all the little moments over the years — the inside jokes, the sense of pride after executing a successful event, or the excitement of welcoming new students to the campus on Imagine Day. These are just some of the good memories I’ll take away from my time at UBC.

How are you involved outside of your academics at UBC?

I have loved seeking a variety of involvements outside of my academics — in the past year, I have served as the LFS Student Senator, been on the UBC Student Leadership Conference planning team, and supported the LFS Mentorship Program as a Work Learn student.

I met so many friends through my different involvements and I’ve had such a great time supporting and building community in LFS. I really value the skills and experiences I’ve gained through my involvements, and consider them just as important as my academics!

As you approach graduation this Spring, what advice would you give to new students about how to build community at LFS?

For me, the hardest part was finding community and meeting others as a new student. My best piece of advice would be to keep an open mind to new opportunities no matter how scary they seem, and that it’s never too late to meet others and get involved! Utilize the different programs and resources available to you, and go from there.

How have LFS staff or faculty influenced your road to your potential career?

Big shout-out to the LFS Student Engagement Officer, Thilini Leitan, and the LFS Career Strategist, Rob Kim. The programming and resources they provide for LFS students, and the conversations I’ve had with them have had such an impact on me and have shaped my career directions.

Working in student affairs was definitely something I had never considered, but as I got more involved and began working closely with them both, I realized this was something I wanted to pursue for a career. I am very appreciative for all the support they provide students in the Faculty.

What excites you about becoming a member of the UBC LFS alumni community?

Knowing that even though I’ve graduated and am no longer a student, there are still many ways for me to stay connected with the Faculty. It’s reassuring to see the resources and programming both the Faculty and alumniUBC provide, whether it’s with the new LFS Young Alumni Council or coming back to the LFS Mentorship Program as a mentor.

And finally, what is your favorite place on campus to relax or study?

Hands down The Pod, which is the LFS Undergraduate Society lounge. I don’t get much studying done in there, but you can definitely bet that I am constantly taking a nap on the couches. I do my best work when I am well rested!

Earth Day: Looking at Long-Term Food Production

Earth Day: Looking at Long-Term Food Production

Thorsten Knipfer and Gopal Sharma

B.C. is facing warmer summers. What impact does this have on our food production?

Plant physiologist Dr. Thorsten Knipfer is researching the true water requirements of perennial plants grown in the region, with a current focus on hazelnuts, the only commercial nut crop grown in B.C. and one that is recovering from a recent occurrence of Eastern Filbert Blight disease.

With drought conditions intensifying during the growing season in B.C. due to lack of precipitation, Dr. Knipfer aims to help hazelnut growers maintain yield and crop quality without wasting irrigation water.

His team is delving into understanding the interaction of water and hazelnut plants by looking inside the plant – monitoring water tensions, water evaporation loss from leaves, and observing the fillings status of cells. High-tech devices and data collection are today’s tools of the trade.

“We are collaborating with BC Hazelnut Growers Association and Verdi, a start-up from UBC that is testing precision agriculture,” says Dr. Knipfer. “With Verdi, we’ll be installing water tracking verification systems using third-party sensors placed in hazelnut fields and custom software for data collection and analysis.”

To start, his lab is partnering with two hazelnut growers in the Fraser Valley to install water tracking systems. In addition, Dr. Knipfer’s team will be installing a precision irrigation system at UBC Totem Field to determine irrigation requirements of hazelnut trees.

“Water is one of our most valuable natural resources and sustainable water management through precision agriculture helps to protect our natural ecosystems through water conservation.”

Thorsten’s research was also featured in the Fall 2022 issue of ReachOut magazine. Read “Drought Resistance in Wine Grapes and Hazelnuts” here.

I am a Food Service Supervisor at Peace Arch Hospital. I coordinate and supervise 30 food service workers to ensure smooth food service operation.

How did your time in LFS impact you in your career since graduating?

I got my Bachelor of Science Degree in Nutritional Sciences from LFS, which allows me to get a CSNM (Canadian Society of Nutrition Management) certificate. As the External Executive in LFS, I developed my leadership and organizational skills, enabling me to pursue a career in the health food service industry.

How do you stay connected to LFS and your alumni community?

I reach out to fellow alumni who work in similar industries, either having an in-person meet up or connecting via LinkedIn. By connecting, I grow my university life and career networks.

What advice would you give to new students about how to build community at LFS?

1) The LFS Mentorship Program to receive guidance and support from mentors. Mentors share their experience and insights on their studies and career path.

2) Join a student organization, such as LFS Undergraduate Society. You learn how to work in a team and build soft skills to support your future career goals.

What was your favorite hangout while studying at UBC? Your favorite place to eat?

The Rose Garden was my favorite hang out at UBC. The garden is filled with diverse types of roses and smells. It’s a wonderful place for taking pictures, especially during sunset and graduation. I had a lot of memories related to the garden.

My favorite place to eat was Mercante, located on the first floor of Ponderosa Maple House. Their pizza is Italian style made-to-order, with some vegetarian options too. I enjoyed eating while in the restaurant’s study room.
