Please note, I'm not in any way making fun of your fiance.
Please do.
it's more of an internship or paid assistant-ship than a job, really. Again, there are reasons that i don't understand (damn science-talk)..but yeah, i guess they can tell what is passing through any given area at what times of year by monitoring the roadkill surveys. They can also then monitor the effect that like, county guys mowing the shoulders of the road and other small biogeographical changes have in the short term - you'd be surprised what little things like that do to a biome....the lawnmower example...it chases the toads out into the road, so you get an idea of what kinds of toads live in the area, then while the grass is short you get all the toad-hunting birds, lizards and small mammals, etc etc etc.
Although it is disgusting....it is an interesting study.
