Natural history of canopy-dwelling beetles: More than just ‘Fun Facts’

This is the second post by undergraduate student Jessica Turgeon – she’s doing an Honour’s project in the lab; here’s her first post that introduces the project.  Since that first post, Jessica has spent a LOT of time at the microscope, and has identified over 120 species of spiders and beetles from forest canopies and understory habitats.

Every species has a different story to tell and each one of these is equally interesting. I sometimes think about natural history as ‘fun facts’: something interesting about an organism (or species) to tell children so that they can appreciate nature. As my time at McGill progressed and my knowledge of the natural world deepened, I realized that the ‘fun facts’ are actually built upon a very strong scientific foundation, and can help us understand results of research projects. Natural history can sometimes be reduced to ‘fun facts’ but it’s a whole lot more than that!

I decided that perhaps I should look at the natural history of some of my species and maybe this would shed light on some patterns that I’m seeing within the data. The most abundant beetle species was Phyllobius oblongus (Curculionidae) with 69 individuals. Interestingly, we only collected this species in the first half of our sampling season and they were mainly collected on black maple and sugar maple trees. To try and understand why this is so, I turned to the species’ natural history, and to the literature.

These weevils tend to eat fresh leaf shoots and prefer the soft leaves found on maple trees. Once the maple’s leaves are fully-grown, P. oblongus moves on to plants with indeterminate growth, like raspberry bushes (Coyle et al. 2010). This corresponds exactly to our data: the beetles were found on our black and sugar maples during the beginning of summer and then they taper off as the season progressed!

Beetle data: the European Snout Beetle was only collected during the beginning of the season.

Beetle data: the European Snout Beetle was only collected during the beginning of the season.

To make this even more interesting, P. oblongus is an invasive species. Its common name is the European Snout Beetle and was accidentally introduced into North Eastern North America in the early 1900s. While most invasive species are a cause for concern, both the Canadian and American governments largely ignore this species. It may inflict some damage to trees but not enough to be worried about. They’re more annoying to researchers than anything since they congregate in the trees in large numbers!

The second most abundant beetle species in the collections was Glischrochilus sanguinolentus (Nitulidae). This species is native to Canada and rather abundant. Species in this genus are called sap beetles but this species in particular is more commonly called a picnic beetle. Large groups of G. sanguinolentus swarm to picnics since they are attracted to sweet food, which ruins the picnics. In nature, they feed on the sap produced by injured trees – hopefully not an indication that the trees we were climbing were damaged!

The natural histories of species open new doors to understanding how organisms live and interact with one another. I thought that it was strange that P. oblongus completely disappeared from my samples midway through the sampling season and its natural history explained why this was so. Picnic beetles eat the exuding sap of an injured tree so in the future I’ll be on the lookout so that I don’t accidentally climb a broken tree! So really, natural history is more than just ‘fun facts’; it helps us understand patterns and to better understand how our natural world works.

Bog spiders: a serendipitous research project

This is a guest post, written by an Honour’s undergrad student in the lab, Kamil Chatila-Amos. It’s the first of two posts about his work, and the goal of this post is to introduce Kamil and his research project. 

Research can be serendipitous and spontaneous, and that’s certainly the story of how my honour’s project started! I spent last winter working on howler monkeys in Panama (which is a story in itself) and although I adored every second of it, it certainly made me out of touch with the McGill world. When I came back, most of my friends had found themselves a summer research job and even an honours supervisor for the upcoming semester.

So there I was, barely a week after my return, erratically filling out online job applications in the lobby of one of our buildings. I was looking at all kinds of opportunities: herbarium employee in Edmonton, ichthyology assistant in Wisconsin, plant surveying in Vaudreuil, bird surveys in Ontario, insectarium employee in Montreal. I was applying to anything and everything that was still available. Little did I know that the arthropod ecology lab is right next to the lobby… Chris walked by, saw me and stopped to chat. (Well it’s more accurate to say he talked to me while quickly walking to his next meeting)*. Turns out, a student of Terry Wheeler (another entomology Prof. at Macdonald campus), Amélie Grégoire Taillefer, was going to post a job online that very afternoon! She was looking for a field assistant to help her catch flies in bogs in the James Bay area.

A couple days later I was northern-bound! A 15 hour drive north of Montreal is the town of Matagami and about 30 km north of there is Lake Matagami, along which we were staying. In a yurt. A yurt!!! Basically, a large round tent of Mongolian origins. They’re big and this one had a minimal kitchen and shower. But the fact remains that it’s a tent with the isolative properties of canvas. It got pretty cold those first couple weeks and dropped below freezing a few nights. At least it had a fireplace. (It’s actually a great place for people wanting to explore that area of Québec and the owners are wonderful. Go check them out at ecogiteslacmatagami.ca)

The work itself was great. The first week, we explored the area for suitable bogs to install her pantraps. That’s when I realized how awesome bogs are. There are so many things to eat in bogs! Cattails, cranberries, Labrador tea, cloud berries, chanterelles, boletes, black flies…

For the remainder of the trip two days a week were spent visiting our five sites and harvesting the pantraps filled with flies, dragonflies, crickets, spiders and the occasional putrid mouse. The following two or three days we would sort through the samples, separating the lower flies (Nematocera) from the rest.

Ready for some serious bog-sweeping.

After the first week I couldn’t help but notice just how many spiders we were catching. Mostly out of pity I think, I decided to sort out the spiders as well. I felt bad throwing them out… Fast forward to five weeks later and I’m heading back to Montreal with a bagful of vials filled with dead spiders. (My roommates were not very fond of having them in our freezer).

A few weeks later I set up a meeting with Chris and essentially barged into his office with the spiders to ask to work in his lab. It took a while (and quite a bit of convincing) but here I am, sorting through spiders and writing blog posts!

The research project we structured has two components. The first part will look at how the community composition of spiders varies between the five sampled bogs. Second, I’m lucky enough to have the opportunity to try DNA barcoding using COI markers. This part remains very blurry right now**, but I’m very excited to see where it leads.

Kamil_Microscope

Kamil hard at work in the lab!

If it weren’t for serendipity I would not have gone to James Bay this summer. And if it weren’t for being spontaneous, I would not have sorted out the spiders and would not be working in Chris’ lab right now. But spontaneity does have its down sides. I didn’t plan far enough ahead** and in hindsight, I should have collected some insect orders to be able to do a more in depth ecological analysis.

* um, yes, I spend a LOT of time in meetings, and often have discussions and chats with student on my way to and from those meetings!

** for what it’s worth, research is often blurry, and planning ahead isn’t always possible!

Monitoring northern biodiversity: picking the right trap for collecting beetles and spiders

Ecological monitoring is an important endeavour as we seek to understand the effects of environmental change on biodiversity. We need to benchmark the status of our fauna, and check-in on that fauna on a regular basis: in this way we can, for example, better understand how climate change might alter our earth systems. That’s kind of important.

With that backdrop, my lab was involved with a Northern Biodiversity Program a few years ago (a couple of related papers can be found here and here), with a goal of understanding the ecological structure of Arthropods of northern Canada. The project was meant to benchmark where we are now, and one outcome of the work is that we are able to think about a solid framework for ecological monitoring into the future.

A few weeks ago our group published a paper* on how to best monitor ground-dwelling beetles and spiders in northern Canada. The project resulted in over 30,000 beetles and spiders being collected, representing close to 800 species (that’s a LOT of diversity!). My former PhD student Crystal Ernst and MSc student Sarah Loboda looked at the relationship between the different traps we used for collecting these two taxa, to help provide guidelines for future ecological monitoring. For the project, we used both a traditional pitfall trap (essentially a white yogurt container stuck in the ground, with a roof/cover perched above it) and a yellow pan trap (a shallow yellow bowl, also sunk into the ground, but without a cover). Traps were placed in grids, in two different habitats (wet and “more wet”), across 12 sites spanning northern Canada, and in three major biomes (northern boreal, sub-Arctic, and Arctic).

Here’s a video showing pan traps being used in the tundra:

Both of the trap types we used are known to be great at collecting a range of taxa (including beetles and spiders), and since the project was meant to capture a wide array of critters, we used them both. Crystal, Sarah and I were curious whether, in retrospect, both traps were really necessary for beetles and spiders. Practically speaking, it was a lot of work to use multiple traps (and to process the samples afterwards), and we wanted to make recommendations for other researchers looking to monitor beetles and spiders in the north.

The story ends up being a bit complicated… In the high Arctic, if the goal is to best capture the diversity of beetles and spiders, sampling in multiple habitats is more important than using the two trap types. However, the results are different in the northern boreal sites: here, it’s important to have multiple trap types (i.e., the differences among traps were more noticeable) and the differences by habitat were less pronounced. Neither factor (trap type or habitat) was more important than the other when sampling in the subarctic. So, in hindsight, we can be very glad to have used both trap types! It was worth the effort, as characterizing the diversity of beetles and spiders depended on both sampling multiple habitats, and sampling with two trap types. There were enough differences to justify using two trap types, especially when sampling different habitats in different biomes. The interactions between trap types, habitats, and biomes was an unexpected yet important result.

Our results, however, are a little frustrating when thinking about recommendations for future monitoring. Using more than one trap type increases efforts, costs, and time, and these are always limited resources. We therefore recommend that future monitoring in the north, for beetles and spiders, could possibly be done with a trap that’s a mix between the two that we used: a yellow, roof-less pitfall trap. These traps would provide the best of both options: they are deeper than a pan trap (likely a good for collecting some Arthropods), but are yellow and without a cover (other features that are good for capturing many flying insects). These are actually very similar to a design that is already being used with a long-term ecological monitoring program in Greenland. We think they have it right**.

A yellow pitfall trap - the kind used in Greenland, and the one we recommend for future monitoring in Canada's Arctic.

A yellow pitfall trap – the kind used in Greenland, and the one we recommend for future monitoring in Canada’s Arctic.

In sum, this work is really a “methodological” study, which when viewed narrowly may not be that sexy. However, we are optimistic that this work will help guide future ecological monitoring programs in the north. We are faced with increased pressures on our environment, and a pressing need to effectively track these effects on our biodiversity. This requires sound methods that are feasible and provide us with a true picture of faunal diversity and community structure.

It looks to me like we can capture northern beetles and spiders quite efficiently with, um, yellow plastic beer cups. Cheers to that!

If you want a copy of the paper, please let me know and I’ll be happy to send it to you. I’m afraid I can’t publish all of our work in open access journals because I don’t have enough $ to afford high quality OA journals.

** The big caveat here is that a proper quantitative study that compares pan and and pitfall traps to the “yellow roof-less pitfall” traps is required. We believe it will be the best design, but belief does need to be backed up with data. Unfortunately these kind of trap-comparison papers aren’t usually high on the priority list.

Studying natural history by stealth

Natural history can be defined as the search for, and description of, patterns in nature. I see natural history research as a more formal and structured approach to studying and recording the natural world. I also see this kind of research as a branch science that is often driven by pure curiosity. Many well-known and popular scientists are naturalists (ever hear of David Attenborough or E.O. Wilson?), and we can see that curiosity is one of the underpinnings of their work and personalities. Natural history research is, without doubt, very important, but in world of academic research, it sure doesn’t headline as pulling in multi-million dollar grants, nor does “natural history” appear in the titles of high profile research papers.

Is there a place for curiosity-driven natural-history research in today’s science? If so, how do we study it in the current climate of research?

Arctic wildflowers. Worthy of research... just because?

Arctic wildflowers. Worthy of research… just because?

This is big question, and one that we grapple with occasionally during my lab meetings. Most recently this came up because I challenged one of my students when they wrote about how important their research was because “…it hadn’t been done before“. In the margin of their work, I wrote “…so what? You need to explain how your work advances the discipline, and the explicit reasons how your research is important independent of whether or not it has been done before“.

Am I wrong? Is it acceptable to justify our research endeavours because they haven’t been done before?

The context matters, of course: some disciplines are very applied, and the funding model may be such that all or most research is directed, project-oriented. The research may have specific deliverables that have importance because of, perhaps, broader policies, stakeholder interests, or needs of industry. In other fields, this is less clear, and when working in the area of biodiversity science, such as I do, we constantly stumble across things that are new because they haven’t been studied before. And a lot of these ‘discoveries’ result from asking some rather basic questions about the natural history or distribution of a species. These are often things that were not part of the original research objectives for a project. Much of natural history research is about discovering things that have never been known before and this may be part of the reason why natural history research isn’t particularly high-profile.

Here are just a few examples of interesting natural history observations from our work in the Arctic:

This is the first time we observed the spider species Pachygnatha clerki on the Arctic islands!

Wow, we now know that an unknown parasitoid species frequently parasitizes the egg sacs of a northern wolf spider species!

Females of this little pseudoscorpion species produce far more offspring than what had been previously documented!

Now, if I wanted to follow-up on any of these observations, I think it’s fair to state that the research would be curiosity-driven, and not necessarily grounded in a theoretical or conceptual framework. It’s the kind of research that can be rather difficult to get funded. It’s also the kind of research that is fulfilling, and a heck of a lot fun.

I'm likin' these lichens. And surely data about them is required...

I’m likin’ these lichens. And surely data about them is required…

How then do you study such fascinating aspects of natural history? How do you get out to the field to just watch stuff; record observations just for the sake of it; spend time tabulating life history parameters of a species just because it’s interesting?

Perhaps you have the luxury of doing natural history research as your full-time job: You may be able to sit back and have people send you specimens from around the world, and maybe go out on an extended collecting trip yourself. You may be lucky enough (and wealthy enough?) to devote serious amounts of time to “think”, measure and record data about species. Perhaps you can even take a long walk each day to mull over your observations. Maybe you will gather enough observations to eventually pull together some generalities and theories, and perhaps you will get around to writing a book or manuscript about this….

Reality check: Most of us don’t have that luxury. Instead, we chase grants, supervise students, do projects that fit in with our unit’s research area, and publish-or-perish in the current model of academic research. Despite how we might long for the “good old days” of academia, they are gone (at least in my discipline). It’s rare that a University Professor or research scientist is hired to do stuff just to satisfy her or his own curiosity.

That main sound depressing to some, and hopeless, but it’s not meant to be. I do believe there are still ways to do exciting and interesting natural history research, and we can call it research by stealth.

In my field of study, establishing a research programs means getting grant money, and these are often aligned with priorities that matter to government, to policy, or to a particular environmental threat such as climate change or invasive species. It’s important to get these grants, and work with students and collaborators to try to solve some of the large and complex problems of the world. I am not advocating avoiding this. Instead, as we move along with these big projects, there are also countless opportunities to do a little natural history research, by stealth. Our first priority may not be the collection of natural history data, but nothing stops us from finding creative ways to make careful and meaningful natural history observations.

When taking a lunch break on the tundra, take a little longer to watch the Bombus flying by, or write down some observations about the bird fauna in your local study site, even if you aren’t an ornithologist. Keep a journal or sketch a few observations while you are sitting in the back of the field truck on that long drive up to the black spruce bogs. Each year, buy a field guide for a different taxon, and learn new stuff alongside your focused project. This ‘spirit’ of natural history observation is one that I promote to my own students, and I encourage them to follow up on some of these as a side-project to their main thesis research. Often, these end up being published, and end up in a thesis, and they certainly end up informing us more about our study species or study area.

Despite writing all of this, I still think my comment in my student’s writing will remain: we have to look at the importance of our research in the context of the bigger picture – it’s not enough to say something is important because it hasn’t been done before, and I’m not sure a PhD thesis can (or should) be entirely based on natural history observation. I would not be doing my job as a supervisor if I promoted curiosity-driven natural history research as the top priority for my student’s projects. To be candid: they won’t get jobs or publish papers in the higher profile journals (i.e., those ones that matter to search committees), and they won’t be well equipped when they leave my lab and head to another institution.

…But I will promote natural history research by stealth.

I think there is loads of room for curiosity-driven natural history research in today’s science. We may need to be creative in how we approach this, but, in the end, it will be worth it. We satisfy our curiosity, and learn a little more about the world along the way. We will also gain perspective and experience, and my students will be well equipped for a future in which natural history research is valued more highly then it is now.

Meet the lab: Elyssa Cameron

Here’s another in the “Meet the lab” series – written by Master’s student Elyssa Cameron.

Like many in my field, my love of nature and the creatures which inhabit it began much earlier than I can remember. From camping trips to day camps to museums and everything in between, I have always been passionate about understanding the world around me. Whether I was catching butterflies, trying to identify an elusive bird, exploring a new place or simply basking the in the beauty and wonder of an unaltered landscape, I knew that I wanted to be an advocate for nature.

In 2011, this led me to pursue an undergraduate degree at McGill University in Environmental Biology, specializing in wildlife. Here I learned the skills and thought processes that would help guide me on my journey. This is also where I feel in love with ecology and ecosystem dynamics. I was humbled by the enormous web of complexity which governs our world and sought to discover where exactly my interests lay. My search took me to South Africa, where I spent 3 week learning about wildlife management, game ranching, governance of national parks, and the challenges in maintaining healthy, safe, sustainable populations and ecosystems. It was during this trip that I realised that the management and conservation of any ecosystem needed to rest upon a solid understanding of the ecology of the system as well as the interactions of individual species, between different species and between species and their environment. Without this basic knowledge of how something works, one cannot hope to protect it.

With this newfound drive for management and conservation through a better understanding of ecosystem ecology, I signed on to do a Master’s project with Chris Buddle (McGill University) on arctic arthropods in 2014. Having never truly worked on insects and spiders before, I knew such an undertaking would be a challenge; but one that I was excited to take on! The aim of this project is to establish a more comprehensive long-term ecological monitoring program in Cambridge Bay, Nunavut, by linking patterns of vegetation and habitat diversity to arthropod diversity. In this way, we can examine the arctic ecosystem in a more complete way and not as a series of individual pieces. This will allow for more effective management in this rapidly changing ecosystem and will hopefully provide more predictive power for models and policies.

However, to obtain these baseline conditions, we must first collect the data. This took me on my second great adventure – a summer in Canada’s high arctic! For those of you who have not yet experienced the vast and diverse beauty of Canada, it is something I cannot recommend enough. But be forewarned, there are LOTS of bugs – which was great for the Bug Team! Working in association with CHARS (Canadian High Arctic Research Station) the Bug Team was part of a unit of researchers set on better understanding the arctic ecosystem and promoting interdisciplinary collaboration. We sampled spiders, flies, beetles, wasps and others to try and get the most complete view of the species diversity and community structure as we could in such a short summer.

Elyssa’s Arctic Adventures!

While there, we also did a number of community outreach programs to try and get the locals interested in science. We participated in a science night, made insect and butterfly collections to leave at the high school and Sarah Loboda (one of my wonderful lab mates!) organized day camp activities for the kids.

Now back at McGill, I spend most of my days in the lab looking through a microscope. With the general sorting of samples now complete, I am about to embark on my biggest challenge yet: species identifications! Both scary and exciting; but with the great support system here, I’m not worried.

As of January, I will also be co-supervising an intern from the Vanier Wildlife Technicians program with Chris Cloutier (the lab’s resident mosquito expert).

Meet the lab: Crystal Ernst

This is the first in a series of posts where each Arthropod Ecology lab member can introduce themselves. First up is PhD student Crystal Ernst:

I’m a Ph.D. candidate in the final stages of my program: these days I’m crunching out analyses and writing papers as I prepare to submit my thesis at the end of the term. As a community ecologist, I spend a lot of time thinking about how and why different species assemble together in space and time. These questions are foundational to the study of ecology and provide the overall framework for my research program, which uses beetles and other ground-dwelling arthropods to study the structure and determinants of terrestrial animal assemblages.

I have spent my summers conducting field research in gorgeous, remote regions of our northern territories, including Kugluktuk Nunavut and the Dempster Highway in the Yukon. My colleagues, members of the Northern Biodiversity Program, have contributed to the collection efforts as well, resulting in specimens being obtained from twelve different locations in the boreal forest, the subarctic and high arctic, spanning Canada coast to coast. I’m now neck-deep in the joy of interpreting the stories contained in my collection of specimens.

I’ve taken two approaches with this work. First, I’ve used a fairly traditional taxonomic approach to studying these animals: by identifying them morphologically (with a microscope and identification keys), I can associate each individual with a known insect species – although some new species have also been discovered! With this information I can describe the species richness (diversity) and distributions of different beetles in the north, and see which species are associated with each other at different northern locations. Secondly, I’ve looked at my arthropods from the perspective of their ecological functions – their roles in their environments. For example, some insects are responsible for pollenating plants, others are important decomposers, and others still are predators; arthropod assemblages can therefore be described in terms of the diversity and dominance of different functional groups. I am in the process of comparing taxonomic and functional assemblages found across northern Canada, and working to determine what aspects of their ecosystems (things like: temperature, wind, and sunlight; the diversity and structure of the plant community in which they live; soil characteristics) are associated with the way these assemblages are structured, and how they change over time and across space.

A fun complementary topic I’ve researched is the relationships between some high arctic ground beetles and a fascinating group of parasites called hairworms. I found a number of beetles from different locations to be infested with these worms; in one instance almost a quarter of the beetles were infected! The parasites are aquatic as adults and must first infect an aquatic insect (like a mosquito larva) before being transmitted to a terrestrial host (like a beetle) via the predation of the aquatic host by the terrestrial insect. To complete their life cycles, the worms somehow compel the beetles to enter the water, effectively forcing them to drown themselves so that the worms can emerge safely into their aquatic habitat. This discovery suggests an important link between the creatures living in terrestrial habitats and those in aquatic habitats and tells us about the arctic food chain: beetles must be eating mosquitos or other insects that have aquatic larval/immature stages. These prey items may, in fact, be a very important source of food. More work needs to be done to confirm this! In the meantime, I am excited to have found these associations – the fact that these particular species of beetles can be hosts for hairworm parasites is new information, and it appears that the parasite itself is a new species!

When I’m not writing my thesis or putting obscure little black beetles on pins, you can probably find me working at McGill’s Teaching and Learning Services, enjoying my time as a teaching assistant, networking on Twitter, mucking around in my vegetable garden (or putting said veggies in jars), walking my dogs, enjoying nature while canoe tripping with my partner, poking wildlife, or lifting heavy things at the gym. I’m on the hunt for a fantastic postdoctoral position that will allow me to continue studying different communities of living things in other ecosystems, and that factors that affect how they’re put together, and I’m excited about the many opportunities out there!

Expiscor (4 November 2013): the obscure edition

Last week I had a terrific discussion with a twitter friend, and he suggested that many/most of the links on Expiscor are ones that were VERY frequently discussed over various social media sites – i.e., a re-distribution of commonly viewed stories. Of course, that is part of the objective of Expiscor, but I also want to be a provider of stories people haven’t heard about previously. So, CHALLENGE ACCEPTED! This week my goal is to provide links to things that are so weird, and obscure that you will totally surprised. It’s the obscure edition….  Please take the poll at the end of this post to let me know if I succeeded!
