One of the interesting parts of being a scientist is that it requires wearing a lot of different hats.

There's the "Field Biologist" hat, which involves traveling out to exotic locations (like Tucson) to track down obscure organisms, braving the hardships of the wild and the vagaries of the weather. I spend lots of time with maps during this part. This part is awesome.

Then there's the "Experiment" hat, which overlaps with some of the other hats but mostly seems to involve collecting and analyzing data (how I get to this point involves wearing some of the other hats). I like this one because it involves a lot of tangible things: measurements, numbers written on pages, set time frames, chemicals in test tubes, color changes, and occasional exclamations of, "BING!" or "It's SCIENCE!"

Then there's the "Grant-writer" hat, which is how I get money to wear the other hats. It involves convincing other people that the things I do are worth spending money to do--that they contribute to some broader theoretical framework in some way that expands our understanding of the world around us, or some other such nonsense. This alternates between being stressful and rewarding (in my mind I go, "This is a useless waste of time" and then "This explains EVERYTHING!").

Then there's the "Educator" hat, which involves things like blogging about ants, writing popular science articles about them, getting interviewed for podcasts or TV shows, bringing ants into classrooms, or talking about ants with my friends or students. This is inspirational.

There's also the "Mathemetician/Statistician" hat, for figuring out how to make sense of the results of experiments. Mmm, number-crunching. Very rewarding when I finally figure out how to do something.

The "Librarian" hat, for finding out about related research and keeping those publications organized. (Appeals to one's meticulous side)

And the "Manuscript-writer" hat, for making sense of the mathematical outcomes. This one often causes a lot of hair-pulling. Oh sure, I can write, but it can be hard to avoid self-censoring.

Oh, and I shouldn't forget the "Zookeeper" hat, which refers to both mentoring activities (<--joke) and taking care of ant colonies. Somewhat mundane, but necessary. Okay, maybe mentoring activities should fall under a separate "Mentor" hat.

Oh, and there's a "Performer" hat in there somewhere, too, for the presentations I give either here at school or at professional conferences. High stress but ultimately inspirational, especially when other people get fired up by my work.

So it's no wonder I feel kind of busy sometimes.

Today, I am hoping to accomplish the following:
1. Send a draft of my dissertation proposal to 3 of my 5 committee members.
2. Submit a travel grant for a conference in October, which also requires writing a poster abstract.
3. Rewrite 4 articles for Ask-A-Biologist (mercifully brief, but 'twill still take time).
4. Feed and water all of my ant colonies.
5. Make sure my undergraduates feel generally happy and as though they are making good progress (because they are).

It's already 1:00, and I've been able to make some, but not all, revisions to my proposal draft. Wish me luck with the rest.

Whew. Next week is going to be busy, not for any single reason, but for the conglomerate of reasons. Hopefully some good will come from it all. In the very least, I won't be bored!

I woke up tired this morning, but convinced myself to go rowing anyways, and as usual, rowing did not disappoint. It wasn't the most exciting of mornings, but I'm glad I got out there.

Then I came home and used up some leftover buttermilk to make buttermilk pancakes, complete with Herman and sprinkled with poppyseeds and sesame seeds. Oh, and topped with strawberries and whipped cream. Let's just say that I like breakfast, a lot.

Then I went in to school, and finished grading my students' exams, as I'd promised I would. By the time that was finished, I had just enough time to eat a bite of lunch before heading over to hear the first part of a lecture by Peter Singer.

I'm almost glad I wasn't able to stay. I found his supposedly ethical arguments for the humane treatment of animals to be illogical and therefore irritating. I, for one, can think of much more reasonable approaches for thinking or arguing about the subject instead of having to rely on concepts of consciousness (how about a more general concept of relation to the world around us? Why should animals--and only certain animals, at that--get the special treatment?). But I had to run off to office hours, which provided a convenient excuse to leave. For questions, the lecture organizers handed out 3x5 index cards to be passed to the front, so after hearing the brief segment I stayed for, I simply asked why Singer relied on this shaky concept of consciousness instead of appealing to a broader aesthetic. It would have been nice if he had gotten to the question, but I'll never know. Honestly, Elaine Scarry's approach (see On Beauty and Being Just), or Wendell Berry's perspective or David Abrahm's viewpoint would make for a more pleasing argument, in my humble opinion. Yet somehow this guy is a well-renowned dude at Princeton. Go figure.

Seeing the students who came to office hours one last time was touching and a bit sad. I'm going to miss this bunch--they were enthusiastic, sharp-witted and fun. But it will be good for them to move on. I can only hope that something that I've said, advice or otherwise, will stick with each of them and have a positive influence on their lives.

Then I got to have a nice chat with a faculty member who is full of insights, and then ate a bit of dinner before heading over to ceramics, which I realize I'd been looking forward to all day.

You see, last week, I played around with some stains, just to see how they worked since I've finally switched to light-colored clays where stains will actually show. After staining these first four porcelain pieces, I glazed them, and today I finally had a chance to see the results of my labor. And the results have been astoundingly beautiful. I might even take some pictures. I think I've finally found the art that I've been after, that combination of ceramics and painting, and on top of that, an outlet for my fondness for black silhouettes, which started back when I was drawing with compressed charcoal.

After admiring my handiwork, I got to work throwing, which went quite well. I'd bought a bag of B Mix with Sand the week before and had started working with it then, but didn't get very far, so tonight was my first real big test run with the stuff. Compared to the porcelain, and even to the Jamaican (black clay) I'd been using before, it's strong and resilient, though its surface develops a somewhat odd texture. I had one of those nights where I was pleasantly surprised by the fact that yes, I could throw, and am not doomed to a life of throwing bowls.

I threw three tall cylinders, which will be turned into pitchers, as well as some spouts, and now it's the end of a long day and my hands are tired from the work. But it's a good feeling.

Yesterday was a good day, altogether. In the middle of the afternoon, as I was quietly nodding off over a stack of papers in need of grading, a somewhat familiar face said, "Hi, Rebecca!" It was the graduate student of a professor from UT Austin who studies leafcutter ants. Apparently he and this prof were on their way through town on a bit of a collecting tour through Arizona and northern Mexico. This sort of thing happens periodically--U likes to just buzz through without much warning or fanfare while on the middle of these expeditions. I can't blame him, really--the drive over is pretty long, and if I were him I'd want to be spending more time outside digging up ants, too.

Probably the best part of the visit is that it was yet again one of those cases where I've been putting off taking care of a couple of things, and those things eventually came to me instead. Even better, U is incredibly supportive of my research. Yesterday he said, "I think what you're doing is great and I'd like to support it in whatever way I can." You can't get much more supportive than that. We're planning a trip out to visit his lab towards the end of May, which promises to be a great time as well.

It's so nice to have such encounters--they leave me going, "Yay, ants!" instead of "Bleh, grading."

After all that was said and done, I went to ceramics and had a good night there as well. I've been working with porcelain clay, which presents a lot of new challenges, but I managed to throw five out of six pieces of clay that I'd wedged--a pretty high success rate, all things considered.

I can now only hope that the rest of the week continues to go well. We're so close to the end of the semester, and I can hardly wait to have a bit of free time to actually get some research done.
rebeccmeister: (Default)
For those who might wonder, I think the feeling of flying by the seat of one's pants (what's the etymology of that phrase, anyway?) never really goes away in academia. Or maybe that's just how my lab and I function.

Yeah.

I'm incredibly grateful for the proposal-writing seminar that I organized and that a professor volunteered to lead. Incredibly. It leaves my advisor and me much less room for dithering. In part, it's painful to run up against such deadlines, but in the long run it's basically the only way to get myself through this process. (I'm grateful for the pain, I suppose).

Obliquely, I'm referring to the fact that I have to have a one-page proposal prospectus put together by 10 am today, and to the fact that I have just barely managed to pull all of the components together just now. We'll see how it goes. I suspect the very first complaint will be that it's too densely worded.
rebeccmeister: (Acromyrmex)
Today, our lab will have a special set of visitors: a couple of middle-schoolers, along with their teachers and parents. These lucky kids are going to tour several different places on campus, and then will be recording podcasts as part of ASU's Ask-A-Biologist program. The ant podcast and related content are going to be under development until probably June, because we're hoping to get more information together on how to build an ant farm and on cool science experiments with ants. There will also, of course, be some videos of ants, probably hosted on good old YouTube. Stay tuned.

I love this stuff--it's so fun to see people get excited about ants and science. I'm somewhat terrified of how the podcast recording will go, but I think it will be fine once it's over.
rebeccmeister: (Default)
I have to say, I'm eternally grateful for the fact that I required my students write a draft of their lab reports, and then helped them with revisions before having them hand in final copies. It's a relief to be able to have intelligent conversations about their ideas as I grade instead of having to sort through whether or not they've captured the basics for the assignment. Of course, I've only read through two of approximately 42 reports so far...
rebeccmeister: (Wha?)
This week has been INSANE. Lots of meetings, some productive, some ???. A bit of research. Crazy teaching. My goal for the lab this week was to help students locate primary research articles: scientific papers that describe original hypotheses and experiments. This time around, I made students tell me what the causal question (how/why/what causes something), hypothesis, and experiment were. Some students are able to do this relatively quickly, but other students struggle mightily with the concepts. They are absolutely key to understanding how science works, so I have to push them to think things through. But each student selects a different article, and each student must get individual attention to know if their article is appropriate for the guidelines of the assignment. This means I have to think about approximately 24 different subjects over a very short timeline. Long story short, it's exhausting.

What a week. I'll be grateful when it's Saturday. I plan a nice leisurely ride to the Farmer's Market, possibly followed by some more biking, and then a heck of a lot of grading.

Yeah.
rebeccmeister: (Acromyrmex)
I keep on blogging today because I'm trying to work on my dissertation proposal, which means that I'm seeking out distractions instead. Actually, I *feel* like things have been going okay so far today, which is probably even more important than thinking I'm making progress or actually having any measurable indicator. This feeling could be because I don't have any particular pressure to show a definite product for my effort today.
cut for blathering )
Anyway. I'm impressed if you read the above blathering, but if you are in similar straits, perhaps it's useful to you. The interesting part of the day is that I figured out a nifty new way to look at some of my data (new to me, at least). I'm working on trying to understand the relationship between leafcutter ant colonies and their fungus as the colonies grow, and so I measured colony size and fungus size every week for two months in 25 colonies (with more than a little help from my friend [livejournal.com profile] myrmecology, of course). My challenge at the moment is how to depict these things in a way that will allow me to ask and answer interesting questions. There's a positive relationship between colony size and fungus size, but that in itself isn't all that exciting. It's the changes over time in the two factors--are they systematic and regular (fungus and colony grow together), or crazy and irregular (colony grows, fungus shrinks, fungus recovers, colony grows)? And how does that relate to the way that other things grow? I can't say much more than that at the moment, but I'm working on it.
rebeccmeister: (Acromyrmex)
This semester, my awesome undergraduates and I have devised a scheme to keep ourselves on track with the research we hope to accomplish. My objective for this week was to complete some measurements on samples of leafcutter ant trash heaps, and I was moderately successful today. But I thought you'd probably be amused to hear about what this work entails.

First, I should explain how leafcutter ant colonies work, from the perspective of materials management. The ants harvest leaves (hence the name leafcutter), and bring these leafy bits back to their colony. Once they bring the leaves underground, they are carefully licked clean and chewed up into tiny fragments. These freshly cleaned fragments are then attached to the ants' fungus garden, and oftentimes new strands of fungus are carefully planted on the fresh material. The growing fungus is used as food, mostly for the developing young.

Eventually, the fungus uses up all of the accessible nutrients in the leaf fragments, and grows old and dies. At this point, the ants carefully trim out the dead bits, and carry them off for disposal in a trash heap. If they were to leave these bits in the nest, they would attract unhelpful, weedy fungus species. Colonies vary in their garbage management systems: some opt for open-air trash piles, while others create underground dump chambers.

In the laboratory, the ants can't be too choosy about where to leave their trash. The species that I work with generally throws out its garbage in piles in external foraging chambers, which is nice for me because then it's fairly easy to collect. The only trouble is that the ants don't sort their garbage by type: dead ant bodies and minuscule fragments of plaster get incorporated with the used-up fungus. I'm only interested in the used fungus for the moment, so I've had to develop methods to get only what I want. My solution so far has been to develop a miniature sieve to sift out much of the plaster bits, and then to go through the remnants carefully by hand with a dissecting needle and paintbrush, separating chunks of plaster and dead ant bodies from the old fungus bits. Fortunately, a dissecting microscope has aided me considerably with the process, but altogether it's painstaking work. I can only hope that the ant trash will be as informative to my questions as human trash is informative to archaeologists.

I'm currently battling a moderate cold. It's not terrible enough that I can declare, "I'm sick!" and stay home and shirk work, but it has made me disinclined to get up early and row or ride my bike (besides, I can still point to last weekend's adventures as justification to take a break). Altogether, I can't even really complain, as it's the first time I've been sick since The Mono. That doesn't make illness enjoyable, though.

Right before I fall asleep, I am reading The Wind-Up Bird Chronicle, by Haruki Murakami, as recommended to me by [livejournal.com profile] trifold_flame, and it is a pleasing novel for its concreteness and vagueness. It allows me to imagine my own version of scenes with a pleasing photographic quality even as I read the story of someone else. I think this has to do with the mention of everyday objects, particularly foods: a ham sandwich, coffee, hard-boiled eggs. Also, alleyways, houses, tall grass, raindrops.

I have been away from fiction for so long.

Meanwhile, I am tempted to also let myself fall into the grips of a work of non-fiction, a book about a particular set of studies of leafcutter ants in Panama. It's written for a scientific audience, and yet has the pleasing story-telling quality achieved by a set of good writers who write to illuminate and not impress. The difficult balance is that this book blurs distinctions between work and leisure, and I must consider it in conjunction with other considerations for my time.

For quite a while there, I was caught up in trying to treat my time as a precious thing, saving it for something, trying to allocate it cleanly to this or that. But if it is too cleanly compartmentalized, my personhood is severed (this part belongs to work. this part belongs to rowing. this part belongs to cooking. this part belongs to ceramics. I am fragmented.). In contrast, when I do things like riding to Tucson, I feel more restored to myself, especially as I watch the sun arc across the entire sky in the cycle of the day.
rebeccmeister: (Acromyrmex)
Much of yesterday was spent considering the interface between science and society, largely because I can't decide what I want to do after graduate school and because I enjoy getting caught up in the human aspect of science. I'm getting started with an outreach project to teach middle-school teachers how to use ants in the classroom, and so there has been a great deal of initial excitement about those ideas. Then, [livejournal.com profile] myrmecology and I got into one of those "I don't know what I'm doing with my life" conversations. Taking a quick inventory, I'm guessing that that conversation isn't ever going to stop--my father is still asking that question, after all, and he's had many more years to work on it.

Then, teaching in the evenings is kind of difficult for me, because I have a hard time concentrating on other things beforehand and get really wound up afterwards. My students were a lot of fun, however, and patient with my fuzzy presentation of science. On the one hand, I'm a bit frustrated that my presentation was so fuzzy, but on the other hand, it's probably a more accurate picture of how science ends up working. I just hope they continue to keep thinking carefully as they write, and continue to ask a lot of good questions. That's key. I'm enjoying the challenge of trying to figure out how to meet the students at the right level to get them to expand their thinking.

We played Scrabble right after I finished teaching, which felt a bit like chaos upon chaos, but it was good. It's such a valuable chance to catch up with my friends and to expand my vocabulary (with SCART being the most recent amusing addition, as in, "I need to SCART me arse!").

I recently bought new sheets, which I put on my already-too-comfortable bed last night. I blame them for the fact that I had a difficult time getting out of bed this morning. It doesn't help that my plans for the day involve a lot of thinking--I feel as though I'm trying to give birth to entire new ideas all at once, and, frankly, I'm not sure my brain is up to the challenge. I was able to convince myself that I wouldn't be able to get much done if I was tired, and so I slept.

Aside to Manuscript of Doom II: The Sequel: I will be quite glad when you are out of my life. Thinking about one subject is difficult enough--thinking about two simultaneously often makes me want to cry.

I get the feeling that I shouldn't feel so reluctant to talk about my research, but whenever anyone asks how it's going it always seems like an overly complicated question to answer. Actually, Berry's writings have been somewhat comforting and helpful on that account. If one accepts the idea of the unknown and unknowable, and gives up the illusion that science=progress, it changes one's goals as a scientist. In some respects, I think I'm letting go of the idea of making some tremendous revolutionary breakthrough with my research on leafcutter ants, and am instead hoping to emerge with an appreciation for what I can and cannot know about these diminutive farmers.

Dithering

The impending approach of a new semester always inspires me to make grandiose plans for things I can or should accomplish. The largest-looming item on my agenda is my dissertation proposal, which my imagination keeps turning into an insurmountable, vast cliff. I tell myself that I require a certain degree of quietude to write effectively--I was able to take a good crack at the Manuscript of Doom II: The Sequel right before my departure for Seattle because I set aside entire days to work on it. But I'm yet convinced that I could write otherwise, perhaps by developing some writing rituals to aid in focusing.

I also think another part of the problem is a lack of a writing community. Though it's often done in isolation, writing is inherently communal--we write for each other, for our future selves. We seek lasting impact. Most writers seek help as needed while they write, and I've come to realize that I cannot always expect the necessary support from my advisor alone.

I don't expect the answers to these questions to leap out at me suddenly. But it is my hope that I can create a new routine for myself as the semester begins, one that will provide continual encouragement.
rebeccmeister: (Default)
It has been an odd work-week. I spent all of Monday and half of Tuesday working on the Manuscript of Doom II: The Sequel. When I got tired of that, I stopped. On Wednesday, I spent basically the entire day tracing fungus areas in a set of 25 photos--the measurements will help [livejournal.com profile] myrmecology and me determine the amounts of fungus present in leafcutter ant nests as part of a larger project on the subject.

Then I spent basically the entirety of yesterday and half of today rehousing the leafcutter ant colonies that are getting too big for their britches and giving them their food and water and blankies and tucking them in all nice and cozy for the holidays. The ant care work was good for me--it's easy to lose touch with how the colonies are doing unless one checks in on them in a systematic fashion.

Then I wrote up a big list of all of the projects I'm working on and typed up a five-page list of all of the references (research articles) that I have put in the "add to my brains" pile. With the aid of the list, I won't have to carry the entire pile around anymore.

And with that, I think I'll go home. This week wasn't exactly what I expected it to be, but I feel like stuff got done and I'll be ready to dive back in when I get back from Seattle.

Le sigh.

Today I am putting together a poster for a conference presentation next week. Once again, this is the sort of thing perhaps best left up to ye visually/computingly talented types, and yet the science is paramount and I don't have the time to run around making it pretty. Thanks to all who offered assistance with the map project, by the way. I haven't had a chance to do any more work on it, but the test version has given me more ideas.

Back to work.
rebeccmeister: (Default)
I have finished grading exams at last. They're dangerously simple to grade--I deduct points without writing comments, which means I have to be extra-vigilant about reading carefully (reading carefully naturally happens when I grade with comments, but that whole enchilada is much more painstakingly time-consuming).

Overall, I'm happy with my experiment in exam-writing. Their final exam was written around the theme of global warming, although much of it ended up being about Sonoran Desert Toads (I'm sure the herpetophiles enjoyed that). It was also a bit more open-ended than the previous exam, which is always a double-edged sword.

Their responses to a question about the peer-review process were nice to read, but for a couple of questions it looks like either many students didn't read the questions all that carefully or I need to do a slightly better job with the wording. They also had nice, thoughtful responses to a question about research on global climate change (namely, why are studies showing definitive biological consequences due to climate change so rare? How does this affect predictions based on models of climate change?). So that was good. It's such a nebulous concept that I think it's useful to give students some more concrete ideas/thoughts to hang their hats on. And if these students won't think critically about things like climate change, who will?

Altogether, though, I must admit I'm glad to be finishing up with the semester. I didn't quite click as well as I'd like to click with my classes, so I won't miss them much (don't tell them!). Things were reasonably amiable, but the spark just wasn't there. C'est la vie.
rebeccmeister: (Default)
There go 20 hours of my life.

Let me back up for a minute: I was trying to measure the amount of phosphorus in a bunch of different samples. To do so, I basically add some chemicals that react with the phosphorus in the samples and make the samples turn blue. The amount of blue is directly proportional to the amount of phosphorus in the sample.

But how do I attach numbers to these things? Part of the process involves measuring the blueness of a bunch of samples whose phosphorus content I know in advance (because I put all of the phosphorus in there). Then I can create a line graph of the relationship between the amount of blue (measured as a sample's absorbance of light in a spectrophotometer) and the amount of phosphorus. This line is known as a standard curve, and so if I know a sample's blueness, I can use the standard curve to estimate its phosphorus content.

But there are some tricks to this debacle: one's standard curve must be very, very accurate. All of the points of the known samples must line up right on the line, and the samples that are supposed to contain zero phosphorus should not develop any blue color.

I was cautiously optimistic today when I approached the finish line because my zeros were zero. But alas, the points do not line up on the line, so I cannot say with any certainty how much phosphorus is in my samples.

This is a frustrating result after 20 hours of work, and means at least another 20 hours more, if not more than that.

Ugh. Time to sleep, and then I have a dissertation committee meeting first thing in the morning. Double ugh.
rebeccmeister: (Acromyrmex)
Today's work went amazingly well, for a change, which means I might even get to lounge about just a bit before finishing up my stack of grading, writing an exam, and getting prepared for my committee meeting on Monday.

I spent the morning doing more tiny activities: first, I used a fancy machine to grind up samples of leaves, oatmeal, polenta, and ant trash into fine powders. The samples are placed into small plastic tubes along with a miniature marble made of a very hard plastic. These are loaded into a machine that shakes them up and down and back and around at an extremely high speed. In theory, the plastic ball smashes against the material until it is pulverized. In practice, sometimes the plastic ball gets stuck and has to be unstuck by hand and reloaded and shaken until it can't be shaken no more (which is to say, I've come unglued and have started crying and kicking my heels against the floor in frustration--rarely happens, but ugly when it does).

In contrast, today's samples pulverized nicely on the first try, with the exception of the polenta. There always has to be an exception, doesn't there? I finally gave up on the polenta in light of the fact that I already have some data on their phosphorus content.

Step two in this whole enchilada is to weigh out tiny specks of the freshly created powder into glass test tubes. That's how you can tell I do science--there are lab coats and test tubes involved. Oh, and later on there are strangely-colored liquids (fuschia and blue)--but I'm getting ahead of myself. Weighing the powder is not as simple as it might sound. Sometimes the air here is so dry that static electricity causes the leaf-motes to be flung through the air instead of sitting in place to be weighed. So when I put a sample on the balance, it registers a weight, and then the weight gradually decreases and decreases and never settles on a number. On top of that, the balance (scale) that I use to weigh samples can be finicky at times. The first time this happened, it took me a long time to figure out what was going on, and this, too, involved a lot of crying and heel-banging. A wise and patient lab technician's counsel cleared this problem up last time (put samples in teeny-tiny plastic tubes with closeable lids for weighing), but the solution is time-consuming.

Today, the solution wasn't even necessary--no particles flung themselves around, and I was able to use the faster tin-foil weighing method instead of the tubes. Hazaa!

The upshot of all of this is, I was anticipating a 10- to 12-hour day of weighing, if I were lucky. Instead, I finished in 4.5 hours. Oh, and I figured out how to listen to KEXP while weighing, which made everything just that much more civilized (fun, almost).

In case all of this makes you really want to trade lives, well, you might want to wait until after Monday, because the whole process is nowhere near finished. Now that the samples are in the test tubes, I can begin the analysis to measure their phosphorus content. But I won't start that until Sunday because it's another 10-12 hours of work. And only at the very end of that day will I know if the whole process worked, or if I'll have to start all over again.
rebeccmeister: (Acromyrmex)
Anthropologists have it easy: I spent a good portion of today staring at tiny things through a microscope as I painstakingly sorted through ant trash heaps.

The whole thing was actually quite fascinating: over the summer, while [livejournal.com profile] myrmecology and I measured foraging preferences and the total leaf intake of 25 of our leafcutter ant colonies, I also collected up all of the ants' garbage so that I can do a full "garbage-in, garbage-out" analysis. Except...ant trash is complicated. Leafcutter ants are actually quite fastidious little creatures; in our lab nests, the ants will pile together the carcasses of dead ants along with bits of used-up fungus, white chunks of plaster of Paris dug out of the fungus chamber floor (used to keep humidity high in the fungus chamber), and other material that the ants decide is unfit for fungiculture (if we feed them oatmeal, most of the oatmeal ends up in the "reject" pile).

For my purposes, I really only want the chunks of used-up fungus, so I developed a miniature sieve to sift out most of the plaster of Paris, and employed a specially-modified paintbrush to sort through the rest of the material. If you were to come across this paintbrush in your house, you'd probably throw it away, but it's actually one of an entomologist's best friends. The few remaining bristles have been mashed sideways so the brush acts like a gentle, miniature hand for sorting, although I must admit that it isn't quite that simple--static electricity is most unhelpful in this process. Other tools, like forceps, end up knocking stuff around even more, so the trusty brush is key.

Once the trash was sorted, I weighed it. Next, I'll grind it into a powder and will measure its phosphorus, nitrogen, and carbon content. And that will help me understand how leafcutter ants and their fungus affect cycling of these three key elements.
