Spiderday (#13)

After a busy summer, and a lot of time away, I’m pleased to start up Spiderday again. Here are some arachnid-themed links pulled from the web over the past couple of weeks.

Curiosity, passion and science: On the natural history of an Arctic pseudoscorpion

I’m pleased to announce a publication about the natural history of a tiny, wonderful arachnid: the pseudoscorpion Wyochernes asiaticus.

I’ve published quite a few papers, but this one is really special: it’s special because it’s about an obscure creature for which virtually *nothing* was known. It’s about a species with a fascinating distribution. To me, it’s an epic tale about a species that nobody really cares that much about. It’s special because it is research that was done just out of pure curiosity and fascination: there was no larger purpose, no great problem to solve, and no experiments to run*. It was based on observation and observation alone, and it was a long slog – done over many, many years (it took about 7-8 years to pull together this story, and this story is really only a prologue). Fundamentally this research was about trying to gather some base-line data about a small animal living in a big landscape.

The big landscape: A river above the Arctic circle: our pseudscorpion friend can be found under the rocks alongside this river.

This work presents some life-history data about a fascinating northern pseudoscorpion species, occurring only in the north-west of North America. As far as I know, it occurs only in regions that were primarily unglaciated during the last glaciation event which covered pretty much all of the northern half of the continent. However, unlike other Beringian species (e.g., the wooly mammoth), this little arachnid did not go extinct but rather continues to thrive in its somewhat unusual habitat under rocks, near rivers or streams.

After collecting and measuring nearly 600 specimens, I can now tell you a bit more about the species distribution in North America, and provide some insights into its life history traits. For example, larger females tended to have higher clutch sizes, a very common and well-known pattern with other arachnids, but there was certainly a paucity of data about this for pseudoscorpions. I also know that all its life stages can be collected in the Yukon in July, and that females can carry around quite a few young (over a dozen!).

But that’s about it. Beyond those fundamental life history measurements and comments on its distribution, the bulk of the species biology remains a mystery.

It may be possible to look at this work as a failure. Heck – a LOT of specimens were collected, by many, many enthusiastic helpers. It took some resources to get the work done (although it was mostly through stealth). A lot of time was spent at the microscope, and it certainly took a bit of time to pull together the paper. And what for? We still don’t know very much about the species: how does it disperse? How does it overwinter? How does it survive flooding of its habitat? How restrictive are the habitat affinities of the species? Do females and males tend to hang around the same rock, or do they mill about with others? What does it eat?

I don’t see this as frustrating, or discouraging, because it’s a start. Before thinking about bigger questions in ecology and evolution, your first need some basics. Only then is it possible to ask broader questions about, say, phylogeography, dispersal limitation, or behaviour.

I hope this work encourages others to seek out and discover new and interesting things about the unnoticed species that walk underfoot, live in tree-tops, swamps, or beneath park benches.

I was very pleased to publish this work in the Canadian Field-Naturalist. Sure, it’s not a ‘high impact’ journal, but it’s a rather special and unique journal for being an excellent location to publish work on the natural history of our species. I hope others consider this journal as an outlet for their curiosity-driven science. Over time, I hope the pendulum does swing, and as a scientific community we really embrace the value of “basic” natural history data. Without a fundamental working knowledge of our species we are hamstrung when it comes to solving the big environmental challenges facing our planet. It’s time to play catch-up. Let’s worry less about impact factors and show some love for smaller journals that are brave enough to keep on publishing about natural history. Let’s spend time observing our natural world, collecting interesting data just because.

I ended my paper with a paragraph about what it felt like to do this research. I am so thankful the editors allowed me to keep this paragraph. It’s important, and reflects my long-standing belief that the lines between a subjective love of nature, and objective observations about nature, should be blurred. They certainly are for me.

In conclusion, observing these marvelous animals in one of the most beautiful areas of the planet, was gratifying, awe-inspiring, and helped solidify a love of natural history. What has been learned is only the prologue to a truly astounding epic: many more discoveries await.
