Nest-building in Basenjis

A not-so-scientific study.

I sometimes wonder about the effects of domestication on dog behavior. I mean to say I wonder idly — not seriously. Because seriously, sometimes dogs are so funny, I wouldn’t want to change them. Mine have always been invaluable boredom-alleviators, as well as entertainers and anti-depressants. Speculating on why they do the things they do provides me with hours of amusement. Reading a book on dog behavior by some expert would just spoil the whole exercise.

Take nest-building. The Old Guy, of course, was Chief High Nest-Builder and Blanket Wrestler. He would scrunch his blanket all over the living room floor in an effort to get it wadded to his exacting specifications. I never knew where he would end up — I always had to just go out of my way as much as necessary not to disturb him when I left the room.

Now it’s The Puppy’s turn. He used to be satisfied with his blanket folded neatly on the floor next to the sofa — truthfully, he used to be satisfied with curling up on the carpet, but the end of winter was pretty chilly here, so I thought he might like a little more insulation. (And, yes, I may be the only person on the planet with basenjis who don’t live on my furniture. When I moved in with my dad and brother, the dogs had to learn a whole new set of rules — The Puppy, of course, grew up as a floor dog.) After months of curling himself up neatly on the folded blanket, said Puppy one day started channeling The Old Guy. He wasn’t happy with a merely rumpled blanket. He had to get it all the way into a tight little wadded-up bundle. Which got me wondering — do dogs in their “natural state” go to such extremes? You would think that beyond a certain amount of “fluffing,” the return on energy expended would bottom out. But I don’t know. Or maybe I’ve just had some especially particular nest fluffers. Or maybe the domestication process — all that selective breeding for being nice to people and not eating them and all — sort of shorted out a few circuits and now they just don’t know when they’re “finished” with their nest. I wonder if I could get funding to do a study. Hmm.

More wonders at HMNS

What with all the blogging and tweeting about last Saturday’s WordCamp at the Houston Museum of Natural Science (HMNS), I suddenly realized that I had never written an account of my trip to Houston last September to see the Terra Cotta Warriors exhibit at HMNS. I was spending a hell of a lot of my time back then firing off job applications, and the rest of my time I spent wringing my hands and wondering how long before I’d be living on the street if I didn’t find a job. Not exactly conducive to generating the kind of energy to write a bunch of upbeat blog content. Nevertheless, I knew I would hate myself later if I passed up the chance to see that exhibit, in spite of how much it might set me back in groceries.

While it didn’t register in my mind at the time that there was any particular significance to the date, I went to Houston on a Wednesday, September 9 (yeah, 09-09-09). (Oh my, oh my, oh my. If stuff like that is supposed to mark significant changes… well, we got some rain here a few days later, after several months of drought. But my job drought continued.)

I took my brother’s camera, and then found out I couldn’t take pictures in the exhibit. I don’t know if taking pictures would be harmful to the terra cotta figures, or whether there are just different policies set up by the owners of each exhibit (I would have been allowed to take pictures of the fossils in the Archaeopteryx exhibit if I’d had the camera with me then). There was a whole little shop full of T.C. Warrior merchandise at the end of the exhibit, so that might have been the deal — don’t let people take their own photos and they’ll buy books and miniature figures, etc. However, there were two figures at the entrance to the exhibit that it was okay to photograph, so I did. Then I proceeded to go around to other parts of the museum and take some more pictures, which I have been meaning to share.

I failed to write down the scientific names for the stuff I was taking pictures of, so we’ll all have to be content with names like “really big geode,” etc. Sometimes I get caught up in being an enthusiast/tourist and forget to be anything else (like scientist, journalist/photojournalist, whatever).

WordCamp and Archaeopteryx

WordCamp was yesterday. As I mentioned elsewhere, I planned to be there, and I was. I drove down in the early morning (had to be there a little before eight to start serving kolaches and coffee) and didn’t get unduly hot on the way, in my un-air-conditioned car. I was able to listen to the keynote address by Matt Mullenweg, one of the founders of WordPress and native son of Houston (although he lives someplace else now), and it was quite entertaining. I got to talk face to face with Houston blogger Shawn Quinn. He and a few other Houstonians started following me on Twitter after I posted the first bit about WordCamp, and I started following them, too. So it was cool to meet Shawn.

The first session I went to was about WordPress 3.0. And why did I think I’d understand any of that? It was in the “Developer Track,” which is that whole other country I mentioned in the earlier post. But the speaker, Stephanie Leary, wrote a book, and if the sample chapter I downloaded as a PDF is any indication, I think I could learn a lot about that country from the book. After that I wanted to sit in on one of the “Blogger Track” sessions, but the room was overflowing with people, so I thought if I was going to have to spend an hour on my feet, I would go see the Archaeopteryx fossil that was on exhibit only for another month (and was the other reason for me to be there in the first place). So I went upstairs to get my ticket. And let me just say how nice it is to have a membership in the museum and be able to go over to the ticket window just for members, where there was no line, and then get the discount on the ticket itself. Sweet.

For those who aren’t fossil fanatics, paleontology buffs, or evolutionary biology groupies, Archaeopteryx (“r-kee-OP-ter-iks”) is one of those precious “missing links” between one major ancient form — in this case dinosaurs — and a more modern one — birds. The first one of these fossils was found in a quarry in Germany famous for its limestone – and its fossils. In fact, fossils often occur in limestone because limestone is formed in marine environments (or formerly marine environments) and objects can become entombed in marine sediments and remain there as the sediment turns to stone. Anyway, the German quarry is at Solnhofen, and in 1861, just a few years after Charles Darwin published On the Origin of Species, a single fossilized feather was discovered. Later, a complete fossil of an animal resembling a lizard but covered with feathers was found in stone of the same age — approximately 150 million years. Eventually nine more fossils were unearthed, and debates carried on for decades over whether they were true birds, true dinosaurs, or a true transitional form from one to the other. There’s not much argument that they are some of the most famous fossils around, though. The one visiting the Houston Museum of Natural Science normally lives in Wyoming, and it was sharing the exhibit with an assortment of other fossils from the same limestone quarry at Solnhofen, Germany.

A lot of the fossils were of fish, which makes sense if the limestone started out as ocean bottom sediment. There were even fossil Coelacanth (SEE-la-canth), a type of ancient fish belonging to a group called the “lobe-finned fish,” which were thought to be the transitional form between fish and amphibians. A few living Coelacanths (the scientific name of the surviving form is genus Latemeria , with two distinct species) were found in deep ocean environments off the coast of South Africa in the late 1930′s, and Indonesia as late as 1998. Hanging on since the Cretaceous Period, when they disappeared from the fossil record.

After I worked my way through the fossil fish, turtles and lizards, a few plants, and some surprising insect fossils, and some truly gorgeous brittle stars, I arrived “in the presence.” The “Arky” fossil was grouped with some other fossils I wasn’t expecting, and the planners of the exhibit had truly saved the best for last. Pterosaurs! I went to see Archaeopteryx because it’s a beautiful fossil with a unique place in the fossil record, but I was always nuts over pterosaurs — the flying dinosaurs. I have a book about them. I have a… well, let me illustrate.

 

"Swoop," with a Cretaceous friend

Yes, it’s a Beanie Baby. Yes, there were Beanie Baby dinosaurs. Yes, I had to have the pterosaur. Funny thing, too. The first  pterosaur fossils, of Pterodactylus, were not a whole lot bigger than my beanie baby. They were about the size of sand pipers, according to the labels next to the fossils. As a kid I had imagined them as monstrous huge, which maybe said more about my imagination. But I kind of like the idea of little flying dinousaurs that I could hold in my hands. Okay, more wild imaginings.

Maybe I’ve picked up a bit of computer geek gloss, but I’m still a science nerd at my core. This is still the stuff that rocks my world. I only wish I’d had my camera with me, because they were allowing people to take pictures — something I couldn’t do last fall when I went to see the Terra Cotta Warriors.

Oh, well. I went. I saw. I marveled. Then I went back to Camp.
