Week 5
Ah, I've finally completed averaging and inputting my pH data in a spreadsheet. Next up, population data. However, I've discovered a problem. No one had population estimates of the humpback chub until approximately 1989. Some attribute it to the fact that they're an odd sort of minnow that is undesirable for food purposes and ugly looking. Others say that it's because at one point, there was such an abundance of them that they never would have even been threatened. However, when rainbow trout (the humpback chub's main predator) was introduced in 1960, numbers dropped rapidly. The issue with that is that's around the same time the Glen Canyon Dam was completed. This means that I might have more confounding variables than anticipated. I'll keep you updated. -Marggie
