Landscape structure, insect herbivory, and ecosystem services

I’m pleased to announce a new publication to come out of the lab, with lead author Dorothy Maguire and co-authored by Elena Bennett and Patrick James. In this work, Dorothy ponders and writes about the broader implications of insect herbivory. More specifically, how insect herbivory is affected by landscape connectivity (i.e., the degree to which habitats are linked to each other), and how plant-feeding insects may relate to ecosystem services (i.e., the values and services that humans get from our natural systems).

Important insects when, as caterpillars, eat a lot of foliate: Female (l) and male (r) Gypsy moth, caught in the act.

We certainly know that insects can do all kinds of damage to plants in ecosystems, but do insects in more (or less) connected habitats do more damage? To address this question Dorothy scoured the literature and got the relatively unsatisfactory answer of “sometimes”: 49% of the papers suggest increased connectivity relates to more insect herbivory and 28% of the papers show less herbivory in more connected patches. The lack of a clear answer actually makes quite a bit of sense since every context can be quite different, and not all insects are equal. It is hard to generalize since effects in forests will not be the same as in fields, and insects that are out-breaking (i.e., with major population explosions) may be affected differently than non out-breaking species. Dorothy certainly found these contexts were important. The results were important to illustrate how we need to adapt any management options with close attention to both landscape feature and their interaction with the life-history of the herbivore.

The second part of Dorothy’s work delved deeper into the literature to ask about the effects of out-breaking versus non out-breaking herbivore species on a select suite of forest ecosystem services: effects on timber production, aesthetics, soil formation and Carbon sequestration. There were some interesting results of this and again, any particular effect of herbivory on an ecosystem service was highly sensitive to the outbreak status of the herbivore. For example, the aesthetics of a forest can be positively affected by low levels of herbivory since this may help create pleasant conditions for light infiltration to the forest floor. However, an out-breaking species may defoliate a tree more completely, thus reducing the aesthetic value. Another example is that low levels of herbivory may positively affect timber production because trees may show “compensatory” growth after light feeding by an insect. In contrast, timber production will be negatively affected by high levels of defoliation as this may reduce a tree’s ability to grow. Although some of these results may seem rather logical, Dorothy’s work was unique as it showed how the scientific literature supports the connections between a herbivore’s life-history and key ecosystem services.

Graphs are divided into four sections representing positive and negative effects of herbivory on ES, during non-outbreak (low) vs. outbreak (high) levels of herbivory. Quadrants are coloured differently based on the hypothesized strength of the effect of herbivory on ES: weak (light grey), moderate (dark grey) and strong (black). Proposed relationships are derived from synthesis of the available literature. From Maguire et al.

The last part of the work was focused on building a conceptual framework – a framework that ties together landscape structure, the process of herbivory, and ecosystem services. This is meant to be a road map for any stakeholders with an interest in any or all of those factors. For example, should a forest manager be tasked with understanding how to increase or support a particular ecosystem service, she or he needs also to recognize how that service is tied to important processes such as herbivory, and the related connections to the broader landscape.

This work is novel and important because it links the well known process of insect herbivory to concepts of ecosystem services and to the discipline of landscape ecology. The marrying of these areas is critically important as we face increasing pressures on our natural systems, and the complexity of the systems can be overwhelming. We hope this work piques more interest in this topic, and that the framework Dorothy provides is useful to all the stakeholders.

The Challenges and Opportunities of University Administration: reflections from a Deanlet

A “Deanlet” is a cutesy name for an Associate Dean. I have no idea who came up with this title, but I first heard it from Terry McGlynn about a year ago, just before I started my first year as an Associate Dean of Student Affairs. Yes, it’s been a year. A very quick and exciting year. And a year is a good point to stop, pause and reflect on life as an Associate Dean*.

An Associate Dean is a level of the university administration just below a Dean (who typically oversees a Faculty). A Deanlet helps run a Faculty because there are too many bits and pieces for one person to handle. In my case, I oversee the affairs of undergraduate students in our Faculty (of which there are about 1,400 undergraduates). This includes recruitment efforts, aspects of student records, dealing with and helping students in academic difficulty, sitting on various committees at various levels in the University, working closely with my Faculty’s executive committee to help establish and oversee larger projects, and a myriad of other tasks (for example, reading names at convocation – something I get to do tomorrow!). In my role I spend a lot of time communicating and collaborating with students, staff, professors, and administrators. I see and experience many aspects of our Faculty.

So, let me report and reflect on three challenges with being a Deanlet, and three of the greatest opportunities that the position has offered me in the first year.


1) Perhaps the biggest challenge in my role has been learning how to help students in difficulty. Student wellness is a priority for me, but it’s not always easy to navigate and find the best solutions when students are struggling, and every situation is context-specific so few ‘generalities’ exist. Sometimes the struggles are academic, and sometimes they involve issues of mental or physical health. I’m often on the front line, and have to make difficult decisions: decisions that affect people. This can be stressful and difficult at times, and certainly means the work doesn’t always stay at the office. Thankfully I have received some excellent training, and have a great team to help, I feel supported, and I am gaining experience that will certainly help me into the future.

2) A second challenge is time management: I have meetings scheduled almost every day, and although they are worthwhile and important, they take time. I remain active as a teacher and a researcher, and I will continue to have a lab and teach my classes, but it can be difficult to balance everything. Before becoming a Deanlet I had a high degree of flexibility in my schedule, which is something many Professors value. However, that flexibility is much diminished, and it has required a lot of adapting. I have no regrets and I expected this (and no, I’m NOT complaining about how busy I am), but I would be lying if I didn’t state that this year has been a big adjustment. The other issue around time management is that when many hours are spent in meetings, this means squeezing other work into weird times of the day.

3) Being a Deanlet sometimes places me in a position of having navigate collegiality: being a colleague in one circumstance, but an Associate Dean in another, can be a challenge. I sometime have to make decisions that do not always please my colleagues (e.g., here’s a new policy XYZ that required you to change how you fill in paperwork XYZ), but also collaborate with my colleagues in research projects, in teaching and on committees. Another example is when a student brings an issue to my attention, perhaps in reference to a grade they received – I sometimes need to bring this to the attention of an instructor and these are not necessary simple or easy discussions. We are all adults, of course, but there is sometimes a divide between administrators and academics, and a professor who is an administrator (this is more-or-less the model at my institution) needs to be cognizant of the different hats, when to wear them, and how to strike the right balance. That being said, I can honestly say that my colleagues have truly been collegial. In my opinion, our institution runs relatively smoothly and effectively in part because our administrators keep one foot in the classroom and research lab.


1) It may sound cliché, but the best part of my Deanlet position is the people I get to interact with. A professor sees students in a classroom or research lab, and interacts with her or his peers, and certainly a Departmental chair, on a regular basis. A Deanlet gets to do this, and more: I see students for a suite of reasons (beyond teaching), and I meet Profs from many different corners of the University, largely because of the University-level committees I sit on. I also work in an office with *amazing* staff, who really run the show! These are individuals deeply committed to the University, and who have the students’ best interests in mind. A university runs well because of its staff, and the Deanlet appointment has afforded me very new and important perspectives on this. In general, Academic staff do not always appreciate the administrative and support staff, and the stresses and challenges they face. This is among the most valuable lesson that my Deanlet appointment has given me so far.

2) The second reason being a Deanlet is a great opportunity is because it places you in a position to understand the inner workings of a University. I have been able to see how the different arms of the University operate, and been in a position to compare and contrast operations in different Faculties with those in my own. It has allowed me wonderful insights into my institution, and allowed me to be an active player in the future directions of my Faculty, something I had hoped to do as part of this appointment. It is sometimes easy to criticize the ‘administration’ from the outside, but once being part of the process, I am much more sympathetic and sensitive to the reasons why some processes, policies and procedures are a certain way, and I am learning about how the system of collegiality at a University works to make change, and why that change sometimes takes time.

3) From a more selfish reason, a valuable gift of my Deanlet appointment is the constant learning it has provided: every day is different, there are always new projects, and the academic year brings different waves of activity, with each wave bringing its own sense of adventure. I’m the sort of person who thrives on variation, and thrives on new problems to solve, whether it be learning the finer points of a student assessment policy, or figuring out the best wording for recruitment materials. A University is a complex place, and delightful in this complexity. University Administration is another set of doors, levers and handles, and figuring out what they all do, and where they all go, is a good fit for me.

I hope this post provides some insights into the role of an Associate Dean in a University (don’t believe everything you read!). Of course, every University is different, and many of the challenges and opportunities will depend on institutional contexts and culture, but I would also think that some of the challenges and opportunities are relatively general (any Associate Dean’s out there wish to comment, below?). When others are afforded the opportunity for administrative appointments, I hope it’s considered seriously, as it’s certainly been a rewarding experience for me.

I will end with a sincere thanks to all the people who have supported me over the past year. The learning curve has been steep but my colleagues, staff, mentors, and my family have been patient and supportive. I’m excited and feeling ready for the years ahead.


* I’m not 100% sure why I wrote and published this post. And it was one that I wavered on for a while. However, I suppose it’s a way to time stamp my own thoughts, for selfish reasons – at the end of my term as a Deanlet, in four years from now, it will be interesting to see how my perspectives change. Perhaps it also because many people don’t know what a Deanlet does and I wanted to provide a glimpse into this portfolio.

Beetles from the North

I’m super-excited to announce new research from the lab, published yesterday with lead author Dr. Crystal Ernst.

Crystal’s paper focused on taxonomic and functional diversity of beetles across 12 sites in northern Canada, ranging from Labrador to the Yukon Territory, and from the bottom of James Bay all the way up to the tip of Ellesmere Island. This work is result of the Northern Biodiversity Program: a multi-institutional collaborative project about the ecological structure of northern Arthropods.

The paper was titled “Drivers and Patterns of Ground-Dwelling Beetle Biodiversity across Northern Canada” and in this research Crystal sorted and identified over 9,000 beetles from 464 species, and she classified the species by their functional ecology to assess how functional diversity may vary across the large spatial scale of this project. Instead of re-writing a summary here, I thought to use this blog post as an opportunity to reflect on what I see as the critical findings from this work, and why this is a paper that I’m incredible proud to be a part of.

  • To me, one of the more interesting findings of this work was that the functional diversity of beetles varied by latitude: although beetles do many things (e.g., herbivore, decomposers, carnivores), it doesn’t seem like all these functions happen at all latitudes. For example, although we document an impressive number of carnivores at all the sites, they are relatively more common in the more northern locations. This is a bit peculiar, and suggests that food-webs involving arthropods vary in some important ways depending on the biome. We also document that temperature is a major explanatory variable when considering functional diversity, which raises the important question about potential effects due to climate change. Indeed, should temperatures change in the north, this may affect the functional ecology of beetles, which in turn could affect other parts of the system.

  • The research generally supported the well-known pattern in biogeography about how species richness decreases at more northern latitudes. When looking at which environmental variable may explain this pattern, temperature again came out on top. In other words, what beetles are found where is in part due to the temperatures in that region. Climate change scenarios therefore have significant potential effects on beetles in the north: beetles, like most other arthropods, are tightly linked to temperature. Even small changes in temperatures in the north may have big consequences for beetles.
  • One of the other big findings, to me, was the fundamental value of species-level data for an important taxa, across vast areas of Canada. Crystal recorded new Territorial and Provincial records for 15 beetle species, increasing knowledge about northern biodiversity. I’m also pleased that the data are fully available on-line, via Canadensys, so other researchers can access the information, re-analyze data, and benefit from and build upon this work.
  • The Arctic is special: it is a vast, cold, treeless landscape, with blankets of tundra, and permafrost underfoot. But it’s also special for beetles. After Crystal analyzed the community-level beetle data, using ordination methods, it became apparent that assemblages from the Arctic Islands of Canada were distinct from the sub-Arctic and north-Boreal sites. From a conservation perspective this is quite important. To some, the Arctic may come across as a big, ‘life-less’ region, with the odd polar bear roaming about, but in reality it hosts thousands of species, including hundreds of beetle species, and that beetle community is very different from what we find in other parts of North America. Special things deserve recognition and protection.
  • Every journalist I talked to has asked “Why beetles?” This is an easy one to answer: they fill virtually all roles in ecosystems, they are diverse, they are of interest to many people, and they are beautiful. The latter point is an important one, as it is important to capture curiosity and fascination about arthropods.

In sum, this was a terrific project to be involved with, and our lab (and our collaborators) are thrilled that the efforts from the Northern Biodiversity program are showing up in the literature (for more examples, check out this, or this).

And rest assured, there’s more to come…

Earthworms at the Morgan Arboretum

This is a post written by undergraduate student Jessica Turgeon – she’s finishing up a project about earthworms.

When I was a child, you could always find me either in a tree or in the dirt. I liked to follow the ants up into the trees and back down again, where I would switch over to digging for earthworms. I loved the feeling of soil between my hands and thinking to myself that these little worms were responsible for making the soil the way it is. I now know that the process is a bit more complex than this but overall, five year old me was almost right.

JessicaI spent my whole life loving nature, especially those living in it. By high school I became a strong advocate for environmental protection, even helping a teacher create a bylaw in my municipality to stop parents from idling in front of elementary schools. This experience truly opened my eyes to the will power and determination this generation has when it comes to changing old mentalities about the environment.

When choosing a university to go to, there was no doubt in my mind whether I should apply to Environmental Biology at the Macdonald campus of McGill or not. This program combines both of my passions: nature and its diversity and environmental management. I’ve since embarked on an amazing journey that has shaped me as a person.

Being around so many naturalists rekindled my love for earthworms, so much so that I decided that I wanted to conduct a research project about them. With the help of Chris Buddle (McGill) and NSERC USRA, I decided to take on a project detailing their biodiversity at the Morgan Arboretum, a nearby forest.

Earthworms can greatly affect Southern Quebec soils because all of the species found here are invasive1. Forests have evolved without the help of earthworms, meaning that earthworm burrowing action is somewhat of a new experience for the trees1. The worms break up and mix the soil when they crawl, leaving the soil readily susceptible to erosion2. While earthworms are prized by gardeners as natural tillers, this can have drastic effects on hardwood forests2.

It was important to me to find out where certain earthworms were in the Morgan Arboretum and why they were there. Soils vary in their composition and properties, meaning that some are more suitable for earthworms than others. The goal of my project was to analyze three different soil types (sandy, clay, loam) with regard to earthworm species. I did so by sampling in the three soils and by collecting and analysing the soil using basic soil analyses.

I found no earthworms in the sandy soil over the course of the sampling period, strongly suggesting that no earthworms inhabit sandy soils. Sandy soils are too rough and painful for earthworms to crawl through, therefore they are actively avoided. The clay and loam soils had much higher numbers of individuals, with 9 species each. After statistical testing, it was concluded that there is no significant difference between the two soils and it could be said that they are similar in biodiversity. In addition, a strong correlation between particle density (how dense the soil is) and earthworm abundance was found. As particle density increases, to a certain extent, so does abundance.

Earthworm Sampling

To conclude, my data suggests that the clay and loam soils in the Morgan Arboretum are similar in biodiversity, both supporting an equally diverse number of earthworm species. However, the sandy soil does not contain any earthworms, suggesting that this type of soil is incapable of supporting earthworm activities. This is interesting information for soil management, since, in terms of earthworm abundance and biodiversity, clay and loam soils are similar.

Earthworms are essential ecosystem engineers that change the soil to better suit their lifestyle and this is why they are often studied. Hopefully my story has encouraged readers to respect earthworms a bit more; after all, they do much more than be an excellent fish bait!

The effects of Twitter on student engagement and learning

There are lots of ‘feel good’ stories about using Twitter in teaching, and I’ve long been a supporting of using social media in undergraduate classes. But does it work…? What effects does Twitter have on learning?

An example of a student Tweet, used to promote their blog post.

This was a question we decided to tackle in my field biology class, and recently, in a collaboration with Lauren Soluk (as part of her graduate work), we surveyed students about using Twitter in the classroom*. Here are the take-home messages from the work:

  • Students Tweeted over 200% more than what was required as part of the course work
  • Students used Twitter in many different ways, from informal communication, to promoting their own blogs, to asking questions of each other or of the course instructors and TA.
  • Students used Twitter to communicate with their instructor or TA 56% of the time, with their peers 27% of the time, and with people external to the course 17% of the time.
  • 94% of students felt that among-group communication was beneficial (i.e., either ‘yes” or ‘somewhat’) to their learning, and 78% of students surveyed felt Twitter increased this among-group communication.
  • When asked whether Twitter had an impact on how they engaged with the course content, 67% of the students answered ‘yes’ or ‘somewhat’.
  • When asked whether Twitter is a good tool to help student learn in the classroom,  78% of the students answered ‘yes’ or ‘somewhat’.

Interesting, most students surveyed said they wouldn’t continue to use Twitter after the class was over. They certainly preferred other tools (e.g., Facebook) to Twitter. Despite this, the students felt Twitter useful in the context of the field biology class, and could see its value independent of their own personal views.

Overall, the results are impressive, and suggests there are good reasons to consider using social media tools such as Twitter, in a University class. It’s certainly not a tool for everyone (and there are important guidelines to consider), nor would it be useful in all contexts, but it clearly serves an important role in my field biology class. Twitter allows students to engage with different audiences, and helps create a rather novel learning community: a community that can include experts from around the world.

Student for a day (Part 3): operation dissection

This is the third and final post about going back to the classroom: you can find the first post here and the second one here.

We rushed from the lecture hall to the basement of the main teaching complex on campus. I walked down the hall towards the lab, that old familiar smell was in the air: it was the “face-muscle dissection day” in Comparative Anatomy. This took me immediately back to my undergraduate days at the University of Guelph.  There were just over a dozen students in the lab, and the ‘specimens’ (I shall NOT mention what they were!) were sitting on stainless steel lab tables, with the dissection gear at the ready. Scalpel? CHECK. Forceps? CHECK. Scissors? CHECK. It was operation: dissection. I was nervous…. then I was handed rubber gloves and a labcoat. I was WAY out of my element…

The instructor started with an extremely detailed 45 minute lecture, providing an excellent overview of the game-plan for the dissections: the expectations of the students was exceedingly clear, and the instructor’s own deep expertise was obvious.

Checking the notes before the dissection commences...

Checking the notes before the dissection commences…

And then the music went on (yes, music! One of the TAs always picks a lovely selection to work to) and the clang of forceps, scalpels scissors started: the students were off, peeling skin and searching for ever-elusive face muscles. It was hard and tedious work: after 30+ minutes our team had only just begun to expose the first layer of muscles. The students expressed how tough the class was, and how it took an incredible amount of time to study their notes after labs. In addition to their own notes, the textbook, and the laboratory notes, my team was taking photos with their smartphones, and taking some videos to use as future study aids. They have a test coming up soon, and were working hard to remember the content and link the ‘thing’ to the ‘name’. I asked the students why they were taking such a challenging course… surely it was required for their program? It turns out that the course wasn’t required, and the students were taking it because they wanted to. It was one of their favourite classes because it involved ‘doing’ things and involved experiential learning on a topic they were deeply interested in (animal biology). The act of dissecting was how they were learning, and the act of dissecting allowed them to really understand how animals work: from the shape and size of salivary glands, to why certain muscles were more developed than others, or how whiskers are embedded deep under the skin surface.

At one point I looked at the clock and was amazed that a full hour had already passed. I looked up from our specimen (and yes, my lab partners had given it a name…) and did a scan of the laboratory: everyone was hunched over, smiling, and now and then you heard ‘COOL’ and ‘WOW’. They were learning together, learning by doing, and loving it. They loved the challenge of the class and they weren’t watching the clock.

I had to leave and get back to my office, and the instructor came up afterwards to say thanks. I was told that never before had another instructor or Prof stepped into the classroom to see what they were doing. That’s a shame.

With my lab partners.

With my lab partners.

I come away from my “student for a day” experience with some vivid memories, new perspectives, and the following take-home messages:

  • There’s a lot of material! Wow, there was a lot of material! The students are learning a very high volume of content, and this happens day after day after day. No wonder they are sometimes stressed and fall behind. As Profs, we need to perhaps better recognize and respect work loads.
  • Different teaching styles are valuable: from lectures to discussions to hands-on laboratories, the variation was much appreciated. It would be tough sitting through six straight hours of lecture, but varying it between different formats works very well. Education is not, and should not *ever* be uniform. One shoe doesn’t fit all, and there is incredible value to ensuring our students get the variation in educational styles.
  • Spaces are important, perhaps more so than I appreciated before: the physical space itself had a great influence on my time as a student, from the angle of the screen to the placement of the door. The little things matter and the space is a key partner in learning. Variation in available spaces must match variation in different types of courses and instructors. We need big and small lecture halls, well-equipped laboratories, and collaborative learning spaces.
  • Students are bright, motivated, serious, and have high expectations: this is good to recognize. I already felt this about students on my campus, but seeing this first hand in three different classes confirmed my suspicions. We should maintain rigor and approach each course with an expectation that the audience is ready to learn and ready to be engaged.
  • Instructors always rush around from class to class and meeting to meeting, but we sometimes forget that students need to rush around too! There isn’t always time in their schedule to eat, line up for the washroom, or physically get from one classroom to another. This is a reminder for me to end class when it’s supposed to end, and be a little more forgiving when students come in a little bit late.

In sum, I will do this again, and would urge my colleagues to do the same. It’s important to see what students see, learn about different approaches to the classroom, and be sensitive to a full timetable and to the high workload that students experience.

A very special thanks to the students who allowed me to tag along: you were patient, kind, and made the experience extra-special.

Student for a day (Part 2): the lecture hall

This is the second of a three-part series on going back to the classroom: check out the first part here.

So far I was enjoying shadowing students for a day: I was excited after my exposure to the research project course, and was fuelled up on coffee as I checked the schedule, wolfed down my lunch and met my next chaperone. We walked together to a different building and to a more traditional setting: a lecture hall. The class was about animal health, and the content was about a retained placenta in cows, and how this affects bovine health and how the retained placenta might lead to other uterine diseases. The instructor, after setting up the Powerpoint, first took 5-10 minutes to ask the class questions from the last lecture. It was clear that this was a normal start to each lecture as the students had dutifully prepared questions for the instructor, and time and care was taken to address each student. This is a great approach, and although I sometimes do this with my own lectures, I don’t do this consistently at the start of each class. I think the students really appreciated devoting this time to discussion at the start of each of their lectures.

The instructor had carefully prepared slides, and had a very nice pace for the entire 90 minutes lecture. I learned a great deal, from Freemartins, to how to treat a cow with a suspected uterine infection. I was deeply impressed by the depth of knowledge of the instructor: research from peer-reviewed papers was used throughout the lecture, and many anecdotes were used to ground the content. There was a lot of content, and it was also clear that the instructor has high expectations of the students. The instructor was also passionate about the material, and this helped keep my interest.

The view from my seat in the lecture hall.

The view from my seat in the lecture hall.

One of the most interesting experiences for me was being able to view the students’ computer screens from the vantage point of a student! I could see about 6-7 screens, and I had some expectation that Facebook or cruising on web-browsers would occur. To my surprise and delight, students were using their computers largely to take notes: some students had the lecture slides (provided by the instructor before class started) on half their screens and a word processer on another part of their screen and they were moving with ease between the two. This was the definition of effective multitasking. My chaperone had a different approach, and was writing in a spiral-bound notebook. She told me that later on she looks at the lecture slides and cross-references with her hand-written notes as an effective way to study. I was impressed: these students are serious, and have given a lot of thought to the best way to take lecture notes and study. I have previously offered some rather strong opinions about instructors posting Powerpoint slides on-line, but what I was seeing in the classroom was certainly causing me to reflect and reconsider my opinions.

There were three important take-home message for me during this lecture:

  • start each class with questions and answers from the previous lecture
  • bring examples from peer-reviewed literature into lectures
  • recognize that students with laptops in class are using these laptops for class.

After lecture we had to rush (10 minutes between classes is not much time!) through melting snow and mud-puddles to get to the basement of another building for the final adventure for the day…
