I’m free of teaching duties for a few weeks, so my goal for now is to get a paper written summarizing our spider survey results. I’ve been working on figures lately, and here’s a map of our survey sites.
(I also have a boring grayscale map of the same thing, which is probably what I’ll have to use for publication.)
See? We surveyed both sides of the railroad tracks. We should have tried getting more homes in the southeast side of town, though. Not shown are some of our less careful observations of locations outside of garages and sheds, where we’d find many more Araneid spiders. That’s something for another day.
I’ve also been digging deeper into our data — we have all these locations with tallies of all the species present, which is kind of overkill, since the environments we’re looking at are all dominated by just four species, and they’re all coexisting in the same spaces. I’m getting a sense of some of the peculiarities of the distribution, though: I’ve been surprised to see how rare Steatoda triangulosa is around here — we found only one site with that species back in June — and how Steatoda borealis is uncommon as well, but they form these little localized colonies where they are the only Theridiidae present.
Now I’ve got plans for these new angles to pursue, but I have to wait for the world to thaw out and for spiders to rise up again.
