As part of a continuing series of Canadian Entomology Research Roundups, here’s what some Canadian entomology grad students have been up to lately:

From the authors:

Finn Hamilton (University of Victoria)

It is now well known that the majority of insects host symbiotic bacteria that have profound consequences for host biology. In some cases, these symbioses can protect hosts against virulent parasites and pathogens, although in most cases it remains unclear how symbionts achieve this defense. In this paper, we show that a strain of the bacterium Spiroplasma that protects its Drosophila host against a virulent nematode parasite encodes a protein toxin. This toxin appears to attack the nematode host during Spiroplasma-mediated defense, representing one of the clearest demonstrations to date of mechanisms underpinning insect defensive symbiosis.

The Emerald Ash Borer (Agrilus planipennis Fairmaire, EAB) is a buprestid pest of ash trees in North America. As part of the development of long-term management plans for EAB, several projects detailing the biology and ecology of poorly-known, yet indigenous parasitoids associated with EAB were initiated. One project concerned the mating sequences of the chalcidid parasitoid, Phasgonophora sulcata Westwood. Many insects undertake repeatable actions prior to mating. These are commonly mediated by pheromones. The results of this research were the description of the mating sequence of P. sulcata, and evidence of female-produced pheromones that initiate these actions. Article link

The parasitic wasp genus Ophion (Hymenoptera: Ichneumonidae) is almost entirely unknown in the Nearctic region, with the vast majority of species undescribed. In this study, we published the first molecular phylogeny of the genus, based on COI, ITS2, and 28S gene regions. While focusing on Nearctic specimens, we also included representatives of most known species from the western Palearctic region and several sequences from other geographical regions. We delimited 13 species groups, most recognized for the first time in this study. This phylogeny will provide an essential framework that will hopefully inspire taxonomists to divide and conquer (and describe!) new species in this morphologically challenging genus. Article link

The relationship between insect body size and life history traits (e.g. longevity, fecundity) has been extensively studied, but the additional effect of body size on behavioural traits is less well known. Using the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Platygastridae) and three of its stink bug host species as a model system, we showed that body size differences were associated with a change in a suite of not only life history parameters (longevity, egg load, egg size), but also several behavioural traits (walking speed, oviposition rate, host marking speed). Our results highlight how the entire phenotype (behaviour and life history) has to be considered when assessing associations between body size and fitness. Article link

Insect wings often have directional roughness elements- like hairs and scales- that shed water droplets along the grain, but why are these elements not always pointing in the same direction? We proposed that three strategies are at play. Droplets should be (1) shed away from the body, (2) shed as quickly as possible and (3) forced out of “valleys” formed between wing veins. A mathematical model combining these three strategies fits the orientation of hairs on a March fly wing (Penthetria heteroptera) quite well, and could readily be applied to other species or bioinspired materials.

Cet article fait partie d’une série continue de rassemblement de la recherche entomologique canadienne (Canadian Entomology Research Roundups). Voici ce que les étudiants de cycle supérieur canadiens ont fait récemment:

De la part des auteurs:

Finn Hamilton (University of Victoria)

C’est bien connu que la majorité des insectes sont hôtes à des bactéries symbiotiques qui ont de profondes conséquences sur la biologie de l’hôte. Dans certains cas, ces symbioses peuvent protéger l’hôte contre de virulents parasites et pathogens, même si dans la plupart des cas planent encore un mystère sur la façon dont les symbionts réussissent à atteindre cette défense. Dans cet article, nous avons démontré qu’une souche de la bactérie Spiroplasma qui protège son hôte drosophile contre un nématode parasitaire virulent encode une toxine sous forme de protéine. Cette toxine semble attaquer l’hôte du nématode durant une défense induite par Spiroplasma. Ceci représente, à ce jour, une des démonstrations les plus claires des mécanismes sous-jacents de la symbiose promouvant la défense des insectes. Lien vers l’article

L’agrile du frêne (Agrilus planipennis Fairmaire) est un buprestide ravageur s’attaquant aux frênes d’Amérique du Nord. Dans l’optique du développement de plans de gestion à long-terme de l’agrile du frêne, plusieurs projets détaillant la biologie et l’écologie de parasitoïdes indigènes peu étudiés auparavant ont été amorcés. Un des projets s’intéresse à la séquence de reproduction d’un parasitoïde, Phasgonophora sulcata Westwood. Plusieurs insectes entreprennent des actions répétées avant la reproduction qui sont souvent induites par des phéromones. Les résultats de cette étude sont la description de la séquence de reproduction de P. sulcata et la preuve que les phéromones produites par les femelles sont à la base de ses actions. Liens vers l’article

Les guêpes parasitiques du genre Ophion (Hymenoptera: Ichneumonidae) sont presqu’entièrement inconnu dans la région Néarctique, où la majorité des espèces ne sont pas décrites. Dans cette étude, nous publions la première phylogénie moléculaire de ce genre, basé sur les régions COI, ITS2, and 28S. Bien que nous mettions l’accent sur les spécimens Néarctique, nous avons aussi inclus des représentants des espèces les plus connus de de l’ouest de la région Paléarctique et plusieurs séquences d’autre régions géographiques. Nous avons délimités 13 groupes d’espèces, la plupart étant reconnu pour la première fois dans cette étude. Cette phylogénie nous fournit un cadre essentiel qui pourra, nous espérons, inspirer les taxonomistes à divisier et conquérir (et décrire!) de nouvelles espèces dans ce genre qui présente de grands défis morphologiques. Liens vers l’article

La relation entre la taille des insectes et certains traits distinctifs (tel que la longévité, la fécondité, …) a été largement étudié, mais l’effet additionnel de la taille sur les traits comportementales sont moins bien connus. En utilisant le parasitoïde d’oeuf  Telenomus podisi Ashmead (Hymenoptera: Platygastridae) et trois de ses hôtes punaises comme système modèle, nous avons démontrés que la différence de taille était associé a un changement dans la plusieurs traits distinctifs (longévité, masse d’oeufs, taille des oeufs), mais aussi de certains traits comportementales (vitesse de marche, taux d’oviposition, taux de marquage des oeufs). Nos résultats mettent en relief comment la phénotype complet (comportement et traits distinctifs) doivent être considéré quand nous évaluons l’association entre la taille et la condition physique. Liens vers l’article

Les ailes de insectes ont souvent des éléments directionnels rugueux – comme des poils et des écailles- qui perdent des gouttes d’eau dans le sens des éléments, mais pourquoi ces éléments ne pointent pas toujours dans la même direction? Nous avons proposé que trois stratégies sont en jeu. Les gouttes pourrait être (1) évacuer loin du corps, (2) être perdues aussi vite que possible et (3) évacuer de “vallées” formés entre les veines des ailes. Un modèle mathématique combinant trois de ces stratégies concorde avec l’orientation des poils sur un taon (Penthetria heteroptera) assez bien et pourrait être appliqué à d’autres espèces ou à des matériaux inspirés par la biologie. Liens vers l’article

By B. Staffan Lindgren, Professor Emeritus

A while back, a paper accepted by The American Statistician entitled “The ASA’s statement on p-values: context, process, and purpose” was posted to the American Statistical Association website. The gist of the paper was that many disciplines rely too much on the p-value as the sole indicator of research importance. Not surprisingly, the paper received considerable attention.

Over my career, I had a love-hate relationship with statistics, knowing just enough to be dangerous, but not enough to really understand what I was doing. Consequently I relied on packaged software and/or colleagues or students who were more quantitatively minded than myself. For example, I generally made sure that a graduate student committee had at least one member with some strength in statistics to make sure I would not leave the candidate stranded or led astray. So if you read my thoughts below, keep in mind that I tread on very thin ice here. I fully expect some disagreement on this, but that is the way it is supposed to be. Ultimately it is your responsibility to understand what you are doing.

The approaches and tools for statistical analysis have changed a lot since my student days, which was at the dawn of mainframe computers for general use, on which we could use a software package called Textform rather than typing the thesis on a type writer as I (read “a secretary I hired and almost drove to depression”) did for my masters. My first visit to a statistical consultant at Simon Fraser University ended with the advice that “This data set can’t be analyzed, it contains zero values.” The software of choice was SPSS, which did not allow for any complexity, so I did a fair bit by hand (which might have been a good thing since it forced me to think about what I was doing, but certainly did not prevent errors). Later in my career it was sometimes a struggle to decide among differing opinions of statisticians what was and was not appropriate to use, but with a little help from my friends I think I managed to negotiate most of the pitfalls (no pun intended) fairly well.

One of the issues with our reliance on p-values is that it is tempting to do post-hoc “significance-hunting” by using a variety of approaches, rather than deciding a priori how to analyze the data. Data that show no significance often remains unpublished, leading to potential “publication bias”. In part this may be the result of journal policies (or reviewer bias), which tends to lead to rejection of papers reporting ‘negative’ results. We have also been trained to use an experiment-wise alpha of 0.05 or less, i.e., a significant result would be declared if the p-value is lower than 0.05. There are two problems with this. First, it is an arbitrary value in a sense, e.g., there really is no meaningful difference between p=0.049 and 0.051. Furthermore, the p-value does not really tell you anything about the importance of the result. All it can do is give some guidance regarding the interpretation of the results relative to the hypothesis. I have tried to make students put their research in context, because I believe the objective of the research may dictate whether or not a significant p-value is important or not. I used to work in industry, and one of the reasons I left was that recommendations I made based on research were not always acted upon. For example, pheromones of bark beetles are often synergized by various host volatiles. But whether or not they are may depend on environmental factors. For example, just after clear cutting the air is likely to have high levels of host volatiles, thus making any host volatile added to a trap ineffective. However, a company may make money by selling such volatiles, and hence they would tend to ignore any results that would lead to a loss of revenue. On the other hand, one could argue that they have the customers’ best interest in mind, because if host volatiles are important under some circumstances, it would be detrimental to remove them from the product.

This leads to my thoughts about the power of an analysis. The way I think of power is that it is a measure of the likelihood of finding a difference if it is there. There are two ways of increasing power that I can think of. One is to increase the number of replications, and the other is to use a higher alpha value. It is important to think about the consequence of an error. A Type I error is when significance is declared when there is none, while a Type II error is when no significance is found when in fact there is one. Which of these is most important is something we need to think about. For example, if you worked in conservation of a threatened species, and you found that a particular action to enhance survival resulted in a p-value of 0.07, would you be prepared to declare that action ineffective assuming that it wasn’t prohibitively expensive? If you have committed a Type II error, and discontinue the action, it could result in extinction of the threatened species. On the other hand, if you test a pesticide, would a significant value of 0.049 be enough to decide to pursue the expensive testing required for registration? If you have committed a Type I error, the product is not likely to succeed in the market place. If the potential market is small, which tends to be the case for behavioural chemicals, it may not be feasible to use this product because of the high cost, which has nothing to do with statistical analysis, but could be the overriding concern in determining the importance of the finding.

One area where the sole use of p-values can become very problematic is for regressions. The p-value only tells us whether or not the slope of the line is significantly different from zero, and therefore it becomes really important to look at how the data are distributed. An outlier can have a huge impact, for example (see figure). As an editor I saw many questionable regressions, e.g., with single points driving much of the effect, but which in the text were described as highly significant.

Fig. 1. An example of where a single point is driving a linear regression. Take it away and there is no apparent relationship at all. Figure from http://www.stat.yale.edu/Courses/1997-98/101/linreg.htm

Finally, we need to keep in mind that a significant p-value does not indicate certainty, but probability, i.e., at p=0.05, you would expect to get the same result 19 of 20 times, but that still means that the result could be the result of chance if you only ran the experiment once. (If you run a biological experiment that yields a p-value close to 0.05 a number of times, you would soon discover that it can be difficult to get the same outcome every time). Depending on the context, that may not be all that confidence inspiring. For example, if someone told you that there was only a 5% probability that you would be get seriously sick by eating a particular mushroom, wouldn’t that make you think twice about eating it?? On the other hand many of us will gladly shell out money to buy a 6/49 ticket even though the probability of winning anything at all is very low, let alone winning the jackpot, because in the end we are buying the dream of winning, and a loss is not that taxing (unless you gamble excessively of course). I consider odds of 1:8000 in a lottery really good, which they aren’t of course, evidenced by the fact that I have never won anything of substance! So relatively speaking, 1:20 is astronomically high if you think about it!

Why am I bothering to write this as a self-confessed statistics phobe? I have mainly to emphasize that you (and by “you” I primarily mean students engaged in independent research) need to think of statistics as a valuable tool, but not as the only, or even primary tool for interpreting results. Ultimately, it is the biological information that is important.

As part of a continuing series of Canadian Entomology Research Roundups, here’s what some Canadian entomology grad students have been up to lately:

Ecology and Evolution

Rasoul Bahreini (University of Manitoba) found that honeybee breeding can improve tolerance to Varroa mites which can help minimize colony losses in the winter and improve overwintering performance (Article link). Rasoul also found that reducing ventilation may be an effective way to manage Varroa mite infestation in overwintering honeybee colonies (Article link), and that Nosema infection restrained Varroa removal success in bees (Article link).

A novel method based on agar-polydimethylsiloxane devices to quantitatively investigate oviposition behaviour in Drosophila melanogaster was described by Jacob Leung and colleagues (York University) (Article link).

Paul Abram (Université de Montréal) and his colleagues found that a predatory stink bug has control of egg colouration, depending on whether it is laying on the top or underside of leaves.  The pigment protects developing embryos against UV radiation (Article link). See also a related post on the ESC blog, an article in the New York Times, and a dispatch article in Current Biology.

Philippe Boucher and colleagues (Université du Québec à Rimouski/Chicoutimi) found that ant colonization of dead wood plays a role in nitrogen and carbon dynamics after forest fires (Article link).

Did you know that ground squirrels have lice – and males have more than females? Neither did we, but Matt Yunick and colleagues (University of Manitoba) recently published an article in The Canadian Entomologist describing their findings (Article link).

Boyd Mori and Dana Sjostrom (University of Alberta) were part of a group of researchers that found that pheromone traps are less effective at high densities of forest tent caterpillars because of competition for pheromone plumes (Article link).

Parasitoid memory dynamics are affected by realistic temperature stress. As part of a collaboration with the University of Palermo (Italy), Paul Abram (Université de Montréal) and colleagues discovered that both hot and cool temperature cycles prevent wasps (Trissolcus basalis) from forgetting. (Article link).

Crisia Tabacaru and Sarah McPike (University of Alberta) studied Dendroctonus ponderosae and other bark and ambrosia beetles and found that competition between the beetles may limit post-fire colonization of burned forest stands (Article link).

Marla Schwarzfeld (University of Alberta) found that tree-based (GMYC and PTP) species delimitation models were less reliable in delimiting test species, and the Nearctic Ophion (Hymenoptera: Ichneumonidae) fauna is much larger than previously thought (Article link).

Where have all the mosquitoes gone? Emily Acheson and colleagues (University of Ottawa) found spatial modelling reveals mosquito net distributions across Tanzania do not target optimal Anopheles mosquito habitats (Article link).

Tyler Wist and colleagues (University of Alberta) found that a native braconid parasitoid (Apanteles polychrosidis) uses host location cues induced by feeding damage on black ash but not on green ash (Article link). Also check out the author’s recent post on the ESC Blog!

Agriculture

Sharavari Kulkarni and colleagues (University of Alberta) discovered that reducing tillage could increase the amount of weed seeds consumed by carabid beetles (Article link).

Physiology and Genetics

Sebastien Boutin and colleagues (Université Laval) are beginning to decode the genetic basis of honeybee hygenic behaviour (Article link).

Investigating the cold tolerance of different Sierra leaf beetle life stages, Evelyn Boychuk and colleagues (University of Western Ontario) found that adults are freeze tolerant, the eggs and pupae are freeze-avoidant, and the larvae are chill susceptible (Article link).

From the Authors:

Shaun Turney, Elyssa Cameron, and Chris Cloutier had this to say about their new article published in PeerJ:

Our supervisor, Prof. Chris Buddle, has always emphasized the importance of voucher specimens for our entomology research. He explained that voucher specimens make our work replicable and verifiable. We wondered how widespread the practice of making voucher specimens among those practicing arthropod-based research. We investigated the frequency of voucher deposition in 281 papers, and the factors which correlated to this frequency. Surprisingly, vouchers were deposited less than 25% of the time! Our paper highlights the need for a greater culture of voucher deposition and we suggest ways in which this culture can be cultivated by researchers, editors, and funding bodies.

From Ikkei Shikano, on two of his recently published articles:

Parents that experience a stressful environment can equip their offspring to fare better in a similar environment. Since this can be energetically expensive for the parent, we asked if parents are exposed to two stressors (nutritional stress and a pathogen), would they equip the offspring for both stressors or would they select one over the other? Cabbage looper moths exposed to a pathogen and poor food quality produced offspring that were highly resistant to that same pathogen. Parents that were given poor food produced offspring that developed faster on poor food. When the parents experienced both stressors, they produced offspring that were resistant to multiple pathogens but did not grow faster on a poor diet (Article link).

Herbivorous insects unavoidably eat large and diverse communities of non-entomopathogenic microbes, which live on the surface of their host plants. Previous studies suggest that consuming non-entomopathogenic bacteria may induce a costly immune response that might decrease the risk of infection by pathogens. But isn’t it wasteful for an insect upregulate a costly immune response to non-pathogens that it ingests with every meal? Within an appropriate ecological context, we show that cabbage looper, Trichoplusia ni, larvae do not induce a costly immune response, indicating that they are adapted to consuming non-pathogenic bacteria that are commonly found on the surface of their host plants (Article link).

From Kate Pare, on an article published by a group of undergraduates taking the Arctic Ecology field course at the University of Guelph:

Our study focused on changes in ant diversity in the area surrounding Churchill, Manitoba between the historic collections made by Robert E. Gregg in 1969 and collections made by students and instructors of the Arctic ecology field course in 2012. Seven ant species were collected in 2012 compared to the five species recorded from 1969. This increase in species richness in the 2012 collection is more likely a result of cryptic molecular diversity that was overlooked in the collection made in 1969 (Article Link, post on the ESC blog).

By Tyler Wist  

The ash leaf cone roller, Caloptilia fraxinella (Ely) (Lepidoptera: Gracillaridae) (Fig. 1) started to get noticed in the cities of the Western Canadian prairies in 1998, well, in Saskatoon, SK at least. I know this because that summer the green ash, Fraxinus pennsylvanica (Oleaceae), in my front yard was covered in cone rolled leaflets and had not been prior to that year. I had just started working for the City of Saskatoon’s Pest Management Program that year and one of our mandates was urban forest insects…not that there was any budget to control them, but it piqued my interest in urban forest entomology.

The following year, Chris Saunders with the City of Edmonton’s Pest Management Program, contacted us in Pest Management and asked if we had seen this cone roller on our ash trees because they had just noticed it on the ash trees in Edmonton. Greg Pohl had identified this leaf miner/leaf roller that year on all species of horticultural Fraxinus in Edmonton and published the identification and some life history of the moth in a 2004 paper (Pohl et al. 2004) along with a brief identification of several parasitoids that were reared from larvae and pupae. The lone braconid, identified to the genus Apanteles and found to be all one species by Darryl Williams of the Canadian Forest Service in Edmonton seemed to be the dominant parasitoid in this complex, but without a species designation not much else about the wasp could be gleaned from the literature.

Chris Saunders suggested that I study the ash leaf cone roller as a master’s project but I digressed from urban forest entomology for a few years into pollination of a nutraceutical/agricultural crop. By this time, the ash leaf cone roller had spread to every ash tree in both cities and often rolled 100% of the leaflets on a single tree. I finally followed Chris’ advice and started a PhD project in Maya Evenden’s lab at the University of Alberta, which was the only lab in Canada that was working on the ash leaf cone roller problem (Evenden 2009). The Apanteles sp. was still the dominant parasitoid and so, along with studies on the chemical ecology of the moth (Wist et al. 2014), I also studied the third trophic level in this system (Wist and Evenden 2013). Of course, I couldn’t go through my studies without knowing what the species designation was for the dominant parasitoid wasp. Fortunately, Jose Fernandez-Triana had just begun his study of the genus Apanteles at the CNC in Ottawa and once Henri Goulet passed along the Apanteles specimens that I had sent for identification he quickly determined that this parasitoid was Apanteles polychrosidis Viereck (Hymenopetra: Braconidae) (Fig. 2).

Fig. 2  – Female Apanteles polychrosidis Viereck (Hymenopetra: Braconidae)

Apanteles polychrosidis kills the ash leaf cone roller larvae before they can chew their emergence “window” that they use to escape the cone rolled leaflet as adults. This behaviour gives a fairly reliable visual cue that a cone rolled leaflet without a “window” has been parasitized by A. polychrosidis because the other parasitoids in the complex emerge after the cone roller has pupated and created its escape route “window”. Unrolling the leaflet confirms the presence of A. polychrosidis if its telltale “hammock-like” cocoon is present (Fig. 3). This type of cocoon is thought to be a defense against hyper-parasitism but as we found (Wist and Evenden 2013) it doesn’t always work out for A. polychrosidis!

Fig. 3 Apanteles polychrosidis Viereck (Hymenopetra: Braconidae) adult above its cocoon and beside the leaflet cone rolled by Caloptilia fraxinella (Ely) (Lepidoptera: Gracillaridae). Note the emergence hole in the side of the leaflet that the wasp chewed to escape.

To assess the percentage of parasitism by this dominant parasitoid I adapted a method that Chris Saunders and I had discussed years earlier for assessing the parasitism of Apanteles sp. on individual trees. For the initial experiment in our paper (Wist et al. 2015) I sampled leaflets to estimate the density of cone rollers on the tree and estimated the percentage of parasitism by A. polychrosidis on two of the common urban species of ash in Edmonton. Apanteles polychrosidis parasitism was higher on black ash, F. nigra, at all sites than it was on green ash, F. pennsylvanica, which can be called differential parasitism and it seems to be common when host larvae develop on two or more host plants, but had not been well studied on trees. When host density and parasitism were graphed, the relationship of parasitism to host density could be visualized by the slope of the regression line, and on black ash, parasitism was independent of host density on black ash, but was negatively density dependent on green ash. In other words, on black ash parasitism is always high but on green ash, parasitism declines as the density of C. fraxinella increases. I ran the same experiment on green and black ash trees in Saskatoon with the same results but we chose to leave them out of the final version of the manuscript.

I was already studying the chemical ecology of C. fraxinella so this was where we looked for an answer to the differential parasitism in the field. I ran a y-tube olfactometer experiment with black and green ash plant material as the attractive source of volatile organic chemicals (VOCs) and this turned out to be rather tricky. I had three treatments that I wanted to test; undamaged leaflets, leaflets damaged by C. fraxinella and leaflets that were mechanically damaged.

First, I tried to bag small seedlings as the source of the plant smell but I couldn’t seal the system well enough to get reliable airflow through the y tube chamber. I had to switch to using leaflets alone which raises the issue of the smell of the leaflets changing once they have been removed from the tree which could be a problem especially in the “undamaged” treatment. I also needed enough female A. polychrosidis hunting for hosts to give me a decent sample size so I had to collect and emerge as many “un-windowed” cone-rolled leaflets as I could in the summer, and hope that they would actually mate and want to oviposit into host larvae at this point in their lives. Another issue was that I couldn’t coax my summer emerged C. fraxinella to lay eggs on ash seedlings to create leaf-mined treatments. Fortunately, a subset of the local population of C. fraxinella had developed a second generation on the new ash leaves that a dying ash tree puts out in July in an effort to save itself. These leaflets became my leaf-mined treatment. Over two seasons with a lot of juggling and timing of three species I was able to gather enough experimental data with the olfactometer to discover that female A. polychrosidis were differentially attracted to the volatile odour cues from each ash species. In green ash tests, they were attracted to the smell of green ash alone but in black ash tests, they were not attracted unless the leaflets were attacked by its host. The “icing on the manuscript cake” was the GC-EAD results by co-authour Regine Gries that showed that 13 compounds in the volatile profile of ash could be sensed by the antennae of A. polychrosidis, and some of them are known to increase in response to herbivore damage.

I’d say that this manuscript is a starting point for further studies on this interesting parasitism system and could accommodate projects from chemical ecology and landscape ecology perspectives at the very least. In fact, Danielle Hoefele and Sarah McPike have already begun projects in Maya’s lab on the FraxinusCaloptilia-Apanteles system. In case you’d like to know more, here is the link to our manuscript published in Arthropod-Plant Interactions.

This year’s 2015 Joint Annual Meeting in Montréal, Québec includes a free lunchtime workshop sponsored by Cambridge University Press that tackles the topic of publishing scientific papers.

Discussion will be led by a three-member panel examining the publication process through the eyes of an author (J. Saguez), a journal editor (K. Floate) and a publisher (D. Edwards).  Following short presentations by each panelist, the floor will be opened for general questions and discussion.

Send us your questions and we will do our best to address them in our presentations.

What makes for a good paper?  Who should I include as co-authors?  How important is the cover letter?  Why is the review process so long?  How can I best respond to reviewer comments?  What journal should I publish in?  What is hybrid open access?  What are predatory publishers?  Why don’t journals make publications freely available?  Knowing the answers to these and other questions can take some of the frustration out of the publication process.

Our goal is to ensure that everyone leaves with a full stomach and new insights to simplify the publication of their next paper!  You can help us by sending your questions to Kevin Floate (Kevin.Floate@agr.gc.ca) by October 23rd.

See you in Montréal!

The field course in Arctic Ecology (BIOL*4610), offered periodically by the University of Guelph, explores ecological relationships in a sub-arctic environment. Based out of the Northern Studies Research Center, the 2-week course takes place in Churchill Manitoba and the surrounding area. That was what we, the students, knew going into the course. What we didn’t know was that course would be, for many of us, a once in a lifetime experience!

There are only three ways of travelling to Churchill, Manitoba: by boat, by plane or by train. Since we wouldn’t be taking the boat route, two options were left: an hour and forty-minute flight, or a three-day journey by rail. The latter is where most of our adventures began (particularly when some of us didn’t purchase a sleeper ticket). There is much to be learned from a long northward trek, from changing ecosystems and changing cultural environments to increasing price tags. Eventually though, the journey’s end came with a comfortable bus ride and an incredibly delicious meal at the Northern Studies Centre. From there on out, it was down to business.

The first week of our course was spent roaming the rugged landscape, learning about the diverse ecosystems the region has to offer while simultaneously trying to prevent ourselves from being carried off by the swarms of (seemingly) abnormally-sized horse flies. We visited sphagnum bogs, fens, the coast (which may have involved kayaking with belugas), a cranberry-laden moraine and the northern extent of the boreal forest. We explored Krummholtz and bluffs, learned that sedges have edges and learned to always be on the lookout for polar bears (at least 2 bear guards please!). The second week however, allowed us the liberty of designing and conducting our own studies.

As a real world example of scientific research in action, the first day of week-two was spent sampling in the footsteps of Robert E. Gregg and collecting ants from his original 1969 study sites (Gregg 1972). Armed with basic instructions on the identification of the 1969 sampled ant species and genera, we visited a total three sites: Cape Merry, the Churchill Welcome Sign, and Goose Creek Bog. At each site, we spent approximately three hours actively searching for ants, breaking open woody debris and digging into moss hummocks. This was true for all but the Goose Creek site where our (brand new bus) tire sprung a leak and we had no choice but to wait there (which may have resulted in a thoroughly sampled population of Odonates) until Alex Smith, one of the instructors walked into town to radio the Churchill Northern Studies Centre for Plan-B transportation. From there it was back to the lab for a crash course on identifying ants to morphospecies, and for many of us, a valuable lesson that all individuals of a species do not look the same (due to individual variation and cryptic diversity). The rest of week-two was spent with groups of students at every site chasing a variety of six-legged, sub-arctic mysteries. Of course, as students of the natural world, no curiosity was overlooked and no opportunity for fun either! Many an hour was spent bluff jumping, polar bear sighting, investigating the Ithaca shipwreck, and in the case of some students, completing a partial reconstruction of an arctic fox skeleton. Needless to say, it was a very short two weeks that passed with discovery and awe.

Going into our field course, I’m not sure any of us thought we would come out of it as published authors. For many of us that participated, the Arctic Ecology field course provided the first real opportunity to actively participate in research outside of the university. The idea that a few days’ worth of collections could be turned into a scientific paper was almost unimaginable. The resulting paper was the first publication that any of us had contributed to. It was exciting to receive the manuscript drafts, and then paper proofs and to know that even aspiring researchers like us could contribute to the knowledge of the scientific community.

During the course, we took high-resolution panoramic GigaPan photographs of the areas we sampled (Smith et al 2013) – you can explore those here. All the DNA barcodes we generated during the course are publicly available for download and exploration. Finally, we wrote about using GigaPans in our Churchill adventures in an article for GigaPan Magazine.

—-

I am a post-doc. I’ve been one for nearly six years. Like many other post-docs, I have been working for over a decade towards my goal: a tenure-track position at a research-intensive academic institution. I enjoy research and teaching, and so a career including both seemed like a logical pursuit. I must be good enough to succeed in this pursuit, otherwise someone would have told me to opt for a different path by now. After all, only a small percentage of Ph.D.s actually become professors. I must be pretty close to achieving this goal, because lately I’ve had several interviews – no offers yet. By now, most of my peers have secured permanent positions, although some have gone on different paths. It must be my turn soon. I had faith in the system; confidence in myself.

Earlier this summer, I was invited to give a talk at a conference, in a session on women in science. I accepted willingly; the subject seemed challenging and relevant. As I began to prepare, I realized I knew nothing about it. So, I did what any scientist would do: I turned to the primary literature on women in science. What I found changed my whole perspective on academia, my career, and most importantly: my life.

I learned that the tenure system is outdated, and filters out many creative and talented people. It was established ca. 1940, when those entering academic careers were mostly men. Assistant professors were expected to live on campus, and work intensively, around-the-clock, on establishing themselves until achieving tenure. Sounds a lot like graduate school, or a post-doc, doesn’t it? There’s not much room in that scenario for having a life outside of this pursuit. It turns out that not much has changed about this in the intervening 70+ years. To make it worse, there are now few jobs and too many of us with graduate degrees competing to fill them. It turns out that women, more often than men, are willing to forgo their academic dreams because of this ridiculousness, in favor of something better – probably a happier life. It seems that there are two issues. One: is it even possible? Women are confronted with the complications of basic biology at the very same time as they would be embarking on a demanding academic career. Most of us are well into our thirties, near the end of our child-bearing years, by the time we’re on the job search. Two: they’re exhausted, wondering if an academic career is akin to never-ending graduate school. In the academic atmosphere, there is intense pressure to do more; for example, publish or perish, fund or famish. Talent and creativity that science badly needs is undoubtedly lost as women and men continue to opt out of this outdated system, and for very reasonable grounds.

I took a long, hard look at my career so far. I’m on my third post-doc. I’ve had two failed relationships and a third that might not make it if I have to move again. I’m not married. I don’t have children. I’m in my mid-thirties, meaning that if I want to have children, I better get situated and do it soon. Maybe academia isn’t for me after all, even though my interests, teaching and research, are so well-aligned with the academic mission. I realized that my adult life so far, 90% career and 10% life outside of work, is a direct product of what I like to call our broken academic system. We need to better understand and voice our discontent with the broken academic system, or it won’t change.

I wondered if others feel the same way. In my field, had others thought of leaving science? And if so, why? Has the disparity in numbers of women and men graduates vs. those occupying professional positions actually changed in recent decades? Most importantly, what allows people to cope with such a rigorous career? I’ve been lucky to have had some great mentors, support from my family, and support and encouragement from the scientific community in my field. Have others had the same kinds of emotional support systems?

My study pursues these questions among three related fields: Forestry, Entomology, and Forest Entomology. In all three of these fields women are not historically well-represented, but this has changed in recent years, especially in Entomology. There are still few women in Forestry. Forest Entomology is a small field with a very inter-connected community, which I hope will provide an interesting contrast to its two larger, sister fields.

Please follow the link below to participate in my study, by completing my survey.

I invite men and women at all stages in their careers, as well as those who are no longer in science, to participate. Please forward this invitation to anyone you know who is no longer in science, but completed graduate school (M.S. or Ph.D.). The results of this study will be published in the primary literature.
