The tension surrounding gender inequality is palpable for nearly all of us lately. It is now well-recognized that women have been, and still are, unfairly challenged in science. Much of this focus is on the current cohort of working women and the biases and personal- or societal-imposed obstacles that they face. My unsettled mind has wandered to the women who came before me. They boldly entered the workforce years ago, as a true minority, and captured many firsts for those of us who followed. What are their stories? How did they achieve happiness and reward in their careers?

Donna , forest entomologist at the U.S. Forest Service, is an excellent example of such a woman. In her first forestry job in 1977, Donna was the only female forester working for a large pulp, paper, and building products company. The men she worked with were baffled as to how she might relieve herself while in the woods all day. In her characteristic, matter-of-fact manner that she is well-known for, she replied, “Well, I pee—what else? I have to remove more clothing than you do, but I pee!”

As entomologists, we should all pay attention to Donna’s story, for two important reasons: She has navigated a career among nearly all male colleagues and, simultaneously, piloted one of the most successful forest insect-management programs in the world for over 20 years running. Donna has consistently orchestrated a suite of forest managers, regulatory officials, and researchers across administrative and jurisdictional boundaries to implement a standardized program that always reaches its goal, every single year.

I was brimming with curiosity about this woman from the moment I met her. How does she run this famous program—and make it look so easy? What are her secrets? Where did she come from? Where does she think the program is going? Where is she going?

When should a non-aggressive exotic species be demoted to a harmless naturalized resident?

Exotic species that establish, spread, and cause substantial damage are demonized as foreign invaders that charge with menacing force across the landscape. Rightly so; those pests threaten to displace or eliminate native species and alter ecosystem functions. Chestnut blight, emerald ash borer, and hemlock woolly adelgid are all excellent examples. What about invaders that aren’t so destructive? Or, at least don’t seem to be at the moment? At what point do we stop monitoring a seemingly innocuous invasive species, especially one that has proved itself a serious pest elsewhere? To make this decision, it’s helpful to know how much the species has affected its new habitat, and whether this impact already has or is likely to change over time. That is exactly what we set out to do with the European woodwasp, Sirex noctilio, in Ontario.

Nearly a decade after the woodwasp was first found in a trap near the Finger Lakes in New York (and then a year later across Lake Ontario in Sandbanks Provincial Park), it still hadn’t killed pines in noticeable numbers, either in the US or Canada. Native to Europe and Asia, this woodwasp has been introduced to several countries in the Southern Hemisphere, where it has been a serious pest in forests planted with exotic pines. By contrast, in North America, it seems that only the weakest trees, those that are already stressed by something else, are killed by the woodwasp. Would forests with many weakened trees allow populations of the woodwasp to build up enough that they could then kill healthy trees in well-maintained forests? Could we find any evidence that this had already happened or would likely happen in the future?

Women have become the majority of graduates in the natural sciences

In my quest to learn more about how people navigate careers in science, I return to the results of my survey, first discussed here last spring. Of the 1156 respondents, 161 (90 male, 71 female) were faculty or mentors who had trained a total of 1704 students in biology, ecology, entomology, or forest entomology between 1971 and 2015. They reported the numbers of female and male students they had graduated (MS or PhD) by time period, and what type of career those graduates occupied (to be addressed in subsequent posts). These data were less biased than other questions in the survey, because they did not rely on self-reports from the students.

In the 1970s, female graduates were the minority – or non-existent in some fields; by the 2000s they were the majority in all fields (51 – 71%, see figure). In the early time periods, females were best represented in entomology, which was also the largest sample: a total of 621 students graduated from 76 mentors. In biology, no female graduates were reported until the 1990s, yet by the 2000s they represented about 70% of graduating students.

Percentage of students who were female and graduated with a MS or PhD in each time period, categorized by field.

These results were similar to those from the US Survey of Earned Doctorates (SED). The SED reported that 55% of all life science PhDs in 2015 were awarded to women (53% for biology, and 48% for the agricultural sciences). Nationally in 1996, only 44% of PhDs in the life sciences were awarded to women, a 10% increase from 1986.

If over half of recent graduates in the natural sciences are women, then the workforce should reflect near equality by gender. It does not (see this study and another one). Among many possible reasons for this inequality (which I will discuss more in later posts), is that the length of a career surpasses time in training (graduate school and postdoctoral appointments) by several decades. This overlap of many graduating cohorts in the workforce makes it difficult to calculate exactly what portion of current professionals should be female, based on trends of graduating students. Some studies account for this caveat; mine did not. In those that did, the workforce was still not equal by gender. In upcoming posts, I’ll examine key gender differences among career types, and potential reasons for those differences.

Quality workdays


For a long time, I measured my work by its products. By that approach I was fairly productive, some days more than others. Big accomplishments were celebratory; long stretches with no measurable accomplishments were dismal. There were too many highs and lows. I needed less intensity, and more evenness. I needed a steady state that could sustain me for the length of a career.

I’ve been prioritizing the quality of my workday lately, rather than its accomplishments. I strive to leave the day ready for something else, not ready to crash, all physical, mental, and emotional energy spent. To achieve this, I’ve been regularly trying to do four things.

One: I build essential breaks into the day, forcing myself to leave a task, even if I’m deeply entranced by it. I vary the length and the focus of these breaks to keep them interesting. The main point is to do something else for a little while. If I’m in my office (aka sitting hunched over at the keyboard and staring intently at a computer screen), I get up and wander around. Maybe I go somewhere in particular; maybe I don’t. There are plenty of physical and mental benefits to this. I stretch tightened muscles, I mobilize my spine, and I reflect on my work. Walking down the hall to sharpen my pencil now serves two purposes! If I’m in the field, I might sit or lay down if the situation permits, or simply leave the area where I’m working to reflect, evaluate the progress and direction of the work, and maybe rest. Physical exhaustion has led me to make some questionable decisions about field projects in the past. I hadn’t realized how frequently I needed to pause to gain mental perspective on the difference between planned and realized outcomes of field work.

Two: I create pauses to transition between major work tasks. This naturally engineers a way to simultaneously reflect and prepare, so all my mental energy can go towards each task – when I’m actually doing it.

Three: I sometimes seek or plan social interactions throughout the day (if they’re not already scheduled as meetings, conferences, etc.), which can force me to focus on something else long enough to feel refreshed when I return to my work.

Four: Most importantly, I exercise during the office-bound workday. For me, physical energy is a product of spent mental and emotional energy. After exercise, I can return to work with more mental clarity than when I left. I’m extremely fortunate in that my job allows me to do this. I sympathize with those who do not have this luxury.

This has all been a real game-changer. Maybe it’s easy for some, but I have struggled to slow myself down, forget about finishing, and learn to enjoy the effort in itself. The rewards are valuable, and more emerge regularly. I’ll share what I’ve discovered so far. The quality workday approach

Stimulates creativity. My best ideas rarely arrive at opportune times. Breaks in the intensity of the workday create space for clever ideas to arrive on their own time.

Improves wellness. Pauses allow me to gauge my energy and stress levels, and adjust my plans accordingly (easier to realize than do). Self-care seems to naturally become a priority.

Promotes actual quality, rather than quantity of work. I’m not in a hurry to finish tasks anymore. When I pause and naturally reflect, I then make useful improvements to projects that I would not have otherwise made had I held myself to unnecessary deadlines.

Enhances time management. I’m forced to plan my daily tasks more carefully, neatly fitting them between the essential breaks.

I’m not an 8-hour on, 8-hour off machine, and it took me more than a decade to realize that. I’m so glad I did. I find ways to do less, rather than more, these days. I imagine the benefits will still be revealing themselves for a long time to come.


Alternatives: Entomologists Who Use Their Hard-Earned Research Skills in Non-Research Careers

This is a series that peeks into the lives of scientists. See other posts in the series.

Graduate school, the traditional conduit to an academic career, trains people to conduct research. Yet, many people with graduate degrees don’t end up in research careers (see here for stats and here for thoughts on alternatives). Research experience equips people with myriad skills that are useful beyond the lab (see here for examples). There seems to be a disconnect somewhere between developing these skills, identifying them, and finding a useful and satisfying place to implement them (a job!) that many face at some point (in graduate school, or in the final months of a grant, or even well into a dissatisfying job).

What are these skills? How do people prepare for and shift away from a traditional research trajectory, especially when surrounded by academic researchers all day!? And how do people find a non-research career that’s a good fit for their interests? There is plenty of self-help literature on this topic (see here, here, here, and here). Also useful, I think, is talking with others about their experiences.

I interviewed three people who have taken unique routes to a career in entomology. Categorized as extension- or science communication-focused, these careers are essential to deliver science and the products it creates accurately to the people who will use it. Maybe more relevant, though, is that these people identified what they liked most about science, kept sight of important things and people in their personal lives, and then built their careers around these priorities.

Field Season

The Ozark Mountains, Arkansas, in May (2005)

The leaves are out; the insects are out. I patiently watched the forest wake up this season. In the midst of another field season I pause to think about what draws me to it, year after year.

People who appreciate the natural world and enjoy outdoor pursuits are often envious of those of us who work outdoors. Rightfully so; the richest and most fulfilling moments of my life have been outdoors. And of course, a love of the outdoors is what initially attracted me to the natural sciences. Yet there is irony behind that naïve envy, because field season makes me feel like a crazy person. So much so that sometimes I think of giving it up for a safe and monotonous desk job. But then, I always return next year. Why?

Field work is rarely akin to a relaxing recreational holiday with friends. It has a habit of revealing and flaunting the worst parts of nature: brambles and thorns, poison plants, biting insects, miscellaneous hazardous wildlife, topography that is precarious at best and life-threatening at worst, sweltering heat and humidity, pelting rainstorms, blizzards, frost-bite worthy temperatures. The work itself is usually repetitive, monotonous, and often physically injurious – or exhausting at the very least. All the hours of travel are ridiculous (especially given that the very resources we are trying to protect are used to fuel that travel). I’ve spent many more hours driving to field sites than actually working in them.

Yet, I readily bolt out of my office for any chance to escape into the woods. The fascination and the drive that fuels a love of field season are, I think, much more complicated than I had realized. Field work awakens a primal sense of attachment and duty to the land that cannot be satisfied in any other way. And it follows an annual pattern that offers a strange sort of comfort.

Planning. Some years are more poorly planned than others, and range from day-of changes to activities neatly scheduled months (even years) in advance. If I can work out a clever balance between people’s schedules, tree and insect phenology, hazardous weather, and random-unforeseen-changes-of-circumstance, then I feel like an organizational master! If not (which is most often the case), then who cares about organized work schedules anyway? Regardless of my planning skills, the work seems to miraculously get done, time and time again.

Preparation. I envision every supply I might need (and often many I don’t need), try to think of whether I have it, someone I know might have it, or if I will have to buy it (grumble), and then I make a huge pile of all of it in the lab, office, or my bedroom. I fluctuate wildly between maximalist and minimalist in this process. Sometimes I’m so over-prepared that I dread putting everything away before I even return from the field. Other times (more often than not), I don’t arrive in the field with everything I need. I forget my raingear often enough that it has become comical. I once forgot my boots and didn’t realize it until we had already driven for three hours. My technician was furious. We went back to get them.

Apprehension. Will the project work? Will all the assumptions that we made about what insects and trees do and when they do it be correct? Probably not. Will the project be a complete failure? Will the entire field season have been a complete waste of time? Never. I always learn something that proves valuable in the future, no matter how meaningless it seems at the time. Is the project important? I wrestle with this one. The big-picture answer, I think, is no. On a smaller scale, it’s important that I make an effort to better understand the world, or to help it sustain itself, and that should be more than enough to satisfy a sense of pride in my work.

Anticipation. This phase usually arrives on the drive. When will we get there? Can we get the hell out of this truck already and get to work? We’re running out of time! But, strangely enough, there’s always enough time. And the work always gets done – even when daylight is escaping.

Chaos. This is almost inevitable. I’ve tried and failed to commit to less to mitigate it. The schedule of events, logistical hang-ups, tree phenology, insect phenology, weather fluctuations, and availability of people manages to saturate my brain at some point during the season. I can’t keep simple things straight anymore. I forget to do my laundry and run out of socks. I forget to brush my teeth. Too much is going on. It’s all so exciting and seemingly important that I don’t even care how scatterbrained I get. No matter how much I forget, the work miraculously gets done.

Rhythm. The chaotic dust has settled. The work has a comforting rhythmic pattern, an eb and flow; my brain and body connect and relax into the effort. The work is difficult, but satisfying. Working alone is easy; working with a team adds some complexity. A little time together and shared physical effort often smooths clashing personalities, and allows the work to flow naturally. Comradery has been established; things are going well.

The peak. I’m excited about how much I’ve accomplished and how quickly I’ve done it. But there is still so much to do…even as I feel myself losing energy. The work is taxing enough that several physical injuries have usually arisen (some more debilitating than others), and I start to look forward to the season’s close. I must now calculate just how far I can go until I can’t go anymore. Attachment and a sense of duty to the land come into focus to carry me through to the finish.

Collapse. I feel like a zombie. I’m so tired, I don’t even know how I manage to get places on my own two feet anymore. It might take weeks to recover. Why then, do I put myself through the rigor year after year?

Repeat. I skipped field season once. I thought it would be a joyous vacation. Instead, I was miserable and felt I had no purpose. So, now I dutifully return to the forest for each new field season, no matter how simple or small my projects seem. I don’t expect to solve the problems of nature. I only know that my presence in the forest, year after year, is certainly needed for my own well-being, and might somehow eventually be useful for the well-being of the planet.

What careers do women in the natural sciences choose?

My recent, and personally relevant, interest in transitions tied to scientific careers developed into two avenues of thought: introspection and external analysis. My first and most recent blog posts both address introspection. In the form of a survey, I looked outside myself to the scientific community to understand more about how others navigate scientific careers. In the coming blog posts I plan to relate the results of this survey, pause on the apparently meaningful patterns, and ponder how we as science professionals can be a better community.

First, I asked respondents to identify the field and career in which they landed.

The response to my survey was overwhelmingly – and perhaps unsurprisingly (I titled it “The role of support systems on success and retention in science”) – female (785 out of 1156 respondents). Below, I show only the results for women, because of the large bias in their sample size. Participants were mostly from the natural sciences of biology, ecology, entomology, and forest entomology. This probably reflected the identity of my professional network, and where the survey was circulated (Entomology Today, the Entomological Society of Canada, my personal Facebook page). There were many student and postdoc participants (386 of 1156 respondents), although because of the transitional nature of these roles, I chose not to include them in the results below.

Of 504 female respondents with graduate degrees (M.S. or Ph.D.), those in the fields of (a) biology, (b) ecology, (c) entomology, and (d) forest entomology (sample sizes in parentheses), categorized by type of career.

Percentage of graduates in the different careers was generally similar among the four scientific fields, with only a few notable differences. Between one-third and one-half of female respondents were in academia (teaching- or research-intensive), often more in research-intensive (20–30%) than in teaching-intensive (10–25%) positions. This is a larger amount than reported by other studies, which have found that 10–26% of graduates remain in academia following graduation (see this article and that article for more). If my results reflect reality, I find it heartening that these life sciences offer more academic opportunities for women (and probably men as well) than other scientific fields. However, the voluntary nature of my survey may have biased this finding. Maybe academics were more likely to notice or more compelled to complete the survey than others.

Less cheerful was that 7–12% of women were no longer in science, which is probably an underestimate, as many in this category may have been unaware of the survey, having lost touch with scientific circles that circulated it. Among the 256 men with graduate degrees, 6% were no longer in science. I hope to follow up with these groups to find out why they left science and what types of jobs they currently occupy. In a broader context, and much more alarming, is this article that reported 32–46% of US doctoral recipients in 2014 had not secured a job upon graduation.

Career choices of forest entomology graduates were most similar to those in the sister field, entomology, and least similar to those in biology and ecology, especially regarding government positions. Women choosing government jobs ranged from 11% in biology to 40% in forest entomology. I suspect that this reflects a greater availability of government jobs in forest entomology. Government agencies that employ forest entomologists include the USDA Forest Service, APHIS, and state Departments of Natural Resources or Agriculture. There are more women in senior research positions in the USDA Forest Service than in comparable positions in academia (Kern et al 2015, BioScience). Kern et al concluded that maybe the hierarchical structure of government promotes diversification more than academia, which operates under considerably less structure. It’s also possible that government positions are more favorable because they offer more work-life balance than academic positions.

From my results, it’s not possible to ascertain whether the relative percentages of women in different careers reflects the availability of those careers for students and postdocs on the job market. Many studies (this one, that one, and another one) have found that the availability of jobs (especially academic jobs) for people with graduate degrees has not kept pace with the increasing rate at which graduate degrees are being awarded. This has naturally resulted in a competitive job market.

I advocate that those of us with secure careers do more to help students and postdocs prepare for and secure science and science-related careers. These people represent the future of our fields. Take an interest in their professional development. Establish collaborative relationships that include them. Expose them to other aspects of your career that may not be apparent from their academic vantage point. Actively make connections with them at meetings, even if it’s only to ask how they are doing or how their project is coming along. People have done these things for me, and it has made all the difference.
