Chris Buddle spends a lot of his time crawling around on his hands and knees in the high arctic. He’s one of the world’s very few experts on the eight-legged creepy crawlies that send a shiver up the spine of most folks. Buddle is an arachnologist and an associate professor of forest insect ecology at McGill University. And he loves spiders. He chatted with us about how the heck he goes about finding teeny tiny animals scuttling around the northern Tundra and why spiders aren’t scary, they’re absolutely fascinating.
Why study spiders?
They’re predators almost entirely within their own food web. They have a significant impact on whatever system they’re in. Whether they run down beaches as tides go out and catch invertebrates or live in the high tundra. No matter where they are, they are always eating other things and sometimes each other. They’re always eating. They have an impact on other animals around them.
They also have very interesting applications as pest control agents. Think of how many pests they eat -- mosquitoes around our houses or crop pests -- they have an impact on pest species.
They have all kinds of uses in the biomedical field. The silk they produce has interesting properties, people use it in the wound care industry as bandages and they use biophysical properties as a model for the development of new fabrics or ropes.
The other thing is that they feed all kinds of other animals. In the high arctic a lot of birds, and when they first arrive to breed, after the snow and ice starts to melt the first thing they encounter as food is spiders.
Do we have any idea how many spiders there are in the world?
We don’t know the number in the world but I’ve done the calculation in individual habitats. It’s true that you’re almost always close to a spider. Density estimates in the arctic show there’s half a spider per meter squared. That’s 4,000 wolf spiders per hectare [about 2.5 acres]. It’s a lot. And that’s just one system. There’s a lot of spiders out there wandering around. So everyone should be an arachnologist!
